Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to methods of treating cancer with a combination of compounds that modulate protein kinase enzymatic activities and the resultant modulation of cellular activities (such as proliferation, differentiation, programmed cell death, migration, chemoinvasion and metabolism). In particular, this invention relates to a compound that inhibits mitogen activated protein kinase (MEK) used in combination with a compound that inhibits phosphatidylinositol 3-kinase (PI3K) signaling pathways.

2. State of the Art

Improvements in the specificity of agents used to treat cancer is of considerable interest because of the therapeutic benefits which would be realized if the side effects associated with the administration of these agents could be reduced. Traditionally, dramatic improvements in the treatment of cancer are associated with identification of therapeutic agents acting through novel mechanisms.

Protein kinases are enzymes that catalyze the phosphorylation of proteins, in particular, hydroxy groups on tyrosine, serine and threonine residues of proteins. The consequences of this seemingly simple activity are staggering; cell differentiation and proliferation; i.e., virtually all aspects of cell life in one-way or another depend on protein kinase activity. Furthermore, abnormal protein kinase activity has been related to a host of disorders, ranging from relatively non-life threatening diseases such as psoriasis to extremely virulent diseases such as glioblastoma (brain cancer).

Protein kinases can be categorized as receptor type or non-receptor type. Receptor-type tyrosine kinases have an extracellular, a transmembrane, and an intracellular portion, while non-receptor type tyrosine kinases are wholly intracellular. They are comprised of a large number of transmembrane receptors with diverse biological activity. In fact, about 20 different subfamilies of receptor-type tyrosine kinases have been identified. One tyrosine kinase subfamily, designated the HER subfamily, is comprised of EGFR (HER1), HER2, HER3, and HER4. Ligands of this subfamily of receptors identified so far include epithelial growth factor, TGF-alpha, amphiregulin, HB-EGF, betacellulin and heregulin. Another subfamily of these receptor-type tyrosine kinases is the insulin subfamily, which includes INS-R, IGF-IR, and IR-R. The PDGF subfamily includes the PDGF-alpha and beta receptors, CSFIR, c-kit and FLK-II. In addition, there is the FLK family, which is comprised of the kinase insert domain receptor (KDR), fetal liver kinase-1 (FLK-1), fetal liver kinase-4 (FLK-4) and the fms-like tyrosine kinase-1 (flt-1). The PDGF and FLK families are usually considered together due to the similarities of the two groups. For a detailed discussion of the receptor-type tyrosine kinases, see Plowman et al., DN&P 7(6): 334-339, 1994, which is hereby incorporated by reference.

The non-receptor type of tyrosine kinases is also comprised of numerous subfamilies, including Src, Frk, Btk, Csk, Abl, Zap70, Fes/Fps, Fak, Jak, Ack, and LIMK. Each of these subfamilies is further sub-divided into varying receptors. For example, the Src subfamily is one of the largest and includes Src, Yes, Fyn, Lyn, Lck, Blk, Hck, Fgr, and Yrk. The Src subfamily of enzymes has been linked to oncogenesis. For a more detailed discussion of the non-receptor type of tyrosine kinases, see Bolen, Oncogene, 8:2025-2031 (1993), which is hereby incorporated by reference.

Since protein kinases and their ligands play critical roles in various cellular activities, deregulation of protein kinase enzymatic activity can lead to altered cellular properties, such as uncontrolled cell growth associated with cancer. In addition to oncological indications, altered kinase signaling is implicated in numerous other pathological diseases. These include, but are not limited to: immunological disorders, cardiovascular diseases, inflammatory diseases, and degenerative diseases. Therefore, both receptor and non-receptor protein kinases are attractive targets for small molecule drug discovery.

One particularly attractive target for small-molecule modulation, with respect to antiangiogenic and antiproliferative activity is MEK. The MEK-ERK signal transduction cascade is a conserved pathway which regulates cell growth, proliferation, differentiation, and apoptosis in response to growth factors, cytokines, and hormones. This pathway operates downstream of Ras which is often upregulated or mutated in human tumors. It has been demonstrated that MEK is a critical effector of Ras function. A large portion of human cancers, including 80% pancreatic, 50% colorectal, and 40% lung cancers, harbor activating Ras mutations. It has been shown that inhibition of the ERK pathway, and in particular inhibition of MEK kinase activity, results in anti-metastatic and anti-angiogenic effects largely due to a reduction of cell-cell contact and motility as well as downregulation of vascular endothelial growth factor (VEGF) expression. Furthermore, expression of dominant negative MEK, or ERK reduced the transforming ability of mutant Ras as seen in cell culture and in primary and metastatic growth of human tumor xenografts in vivo. Therefore, the MEK-ERK signal transduction pathway is an appropriate pathway to target for therapeutic intervention.

Accordingly, the identification of small-molecule compounds that specifically inhibit, regulate and/or modulate the signal transduction of kinases, particularly MEK, is desirable as a means to treat or prevent disease states associated with cancer and is an object of this invention.

Phosphatidylinositol 3-kinase (PI3Kα), a dual specificity protein kinase, is composed of an 85 kDa regulatory subunit and a 110 kDa catalytic subunit. The protein encoded by this gene represents the catalytic subunit, which uses ATP to phosphorylate PtdIns, PtdIns4P and PtdIns(4,5)P2. PI3Kα has been implicated in the control of cytoskeletal reorganization, apoptosis, vesicular trafficking, proliferation and differentiation processes. Increased copy number and expression of PIK3CA is associated with a number of malignancies such as ovarian cancer, cervical cancer, breast cancer, colorectal cancer, and glioblastomas, among others. The tumor suppressor PTEN inhibits cell growth through multiple mechanisms. PTEN can dephosphorylate PIP3, the major product of PIK3CA. PIP3, in turn, is required for translocation of protein kinase B (AKT1, PKB) to the cell membrane, where it is phosphorylated and activated by upstream kinases. The effect of PTEN on cell death is mediated through the PIK3CA/AKT1 pathway.

Thus, an object of this invention is the identification of small-molecule compounds that specifically inhibit, regulate and/or modulate the signal transduction of kinases, particularly phosphatidylinositol 3-kinase, in order to treat, prevent, and/or inhibit diseases and conditions associated with cancers.

Combination therapy has been commonly utilized to overcome drug resistance. Clinical trials of dasatinib or nilotinib (AMN-107) in combination with the current standard CML therapy, ie., imatinib (Gleevec®), are ongoing (ClinicalTrials.gov) Dasatinib in combination with Gleevec® has shown improved efficacy against various Abl mutants except for T3151 in preclinical studies (O'Hare T, Walters D K, Stoffregen E P, et al., “Combined Abl inhibitor therapy for minimizing drug resistance in chronic mycloid leukemia: Src/Abl inhibitors are compatible with imatinib”, Clin Cancer Res. 11, 6987-6993 (2005)). Recently, specific mutations in B-RAF have been shown to confer reduced sensitivity to treatment of cells and tumors with compounds that inhibit MEK (Solit et al. Nature online, pgs 1-5 Nov. 6, 2005). Combination therapys treating multiple kinases pathways should eliminate this reduced sensitivity.

The foregoing merely summarizes certain embodiments of the invention and is not intended to be limiting in nature. These embodiments and other embodiments and embodiments are described more fully below. The patent and scientific literature referred to herein establishes knowledge that is available to those with skill in the art. The issued patents, applications, and references that are cited herein are hereby incorporated by reference to the same extent as if each was specifically and individually indicated to be incorporated by reference. In the case of inconsistencies, the present disclosure will prevail.

DETAILED DESCRIPTION OF THE INVENTION

The following applies to all three sections.

“Yield” for each of the reactions described herein is expressed as a percentage of the theoretical yield.

Some of the compounds of the invention may have imino, amino, oxo or hydroxy substituents off aromatic heterocyclyl systems. For purposes of this disclosure, it is understood that such imino, amino, oxo or hydroxy substituents may exist in their corresponding tautomeric form, i.e., amino, imino, hydroxy or oxo, respectively.

Compounds of the invention are named according to systematic application of the nomenclature rules agreed upon by the International Union of Pure and Applied Chemistry (IUPAC), International Union of Biochemistry and Molecular Biology (IUBMB), and the Chemical Abstracts Service (CAS).

The compounds of the invention, or their pharmaceutically acceptable salts, may have asymmetric carbon atoms, oxidized sulfur atoms or quaternized nitrogen atoms in their structure.

The compounds of the invention and their pharmaceutically acceptable salts may exist as single stereoisomers, racemates, and as mixtures of enantiomers and diastereomers. The compounds may also exist as geometric isomers. All such single stereoisomers, racemates and mixtures thereof, and geometric isomers are intended to be within the scope of this invention.

It is assumed that when considering generic descriptions of compounds of the invention for the purpose of constructing a compound, such construction results in the creation of a stable structure. That is, one of ordinary skill in the art would recognize that there can theoretically be some constructs which would not normally be considered as stable compounds (that is, sterically practical and/or synthetically feasible, supra).

When a particular group with its bonding structure is denoted as being bonded to two partners; that is, a divalent group, for example, —OCH2—, then it is understood that either of the two partners may be bound to the particular group at one end, and the other partner is necessarily bound to the other end of the particular group, unless stated explicitly otherwise. Stated another way, divalent groups are not to be construed as limited to the depicted orientation, for example “—OCH2—” is meant to mean not only “—OCH2—” as drawn, but also “—CH2O—.

In addition to the preferred embodiments recited hereinabove, also preferred are embodiments comprising combinations of preferred embodiments.

Methods for the preparation and/or separation and isolation of single stereoisomers from racemic mixtures or non-racemic mixtures of stereoisomers are well known in the art. For example, optically active (R)- and (S)-isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. Enantiomers (R- and S-isomers) may be resolved by methods known to one of ordinary skill in the art, for example by: formation of diastereoisomeric salts or complexes which may be separated, for example, by crystallization; via formation of diastereoisomeric derivatives which may be separated, for example, by crystallization, selective reaction of one enantiomer with an enantiomer-specific reagent, for example enzymatic oxidation or reduction, followed by separation of the modified and urunodified enantiomers; or gas-liquid or liquid chromatography in a chiral environment, for example on a chiral support, such as silica with a bound chiral ligand or in the presence of a chiral solvent. It will be appreciated that where a desired enantiomer is converted into another chemical entity by one of the separation procedures described above, a further step may be required to liberate the desired enantiomeric form. Alternatively, a specific enantiomer may be synthesized by asymmetric synthesis using optically active reagents, substrates, catalysts or solvents or by converting on enantiomer to the other by asymmetric transformation. For a mixture of enantiomers, enriched in a particular enantiomer, the major component enantiomer may be further enriched (with concomitant loss in yield) by recrystallization.

“Patient” for the purposes of the present invention includes humans and other animals, particularly mammals, and other organisms. Thus the methods are applicable to both human therapy and veterinary applications. In a preferred embodiment the patient is a mammal, and in a most preferred embodiment the patient is human.

“Kinase-dependent diseases or conditions” refer to pathologic conditions that depend on the activity of one or more protein kinases. Kinases either directly or indirectly participate in the signal transduction pathways of a variety of cellular activities including proliferation, adhesion, migration, differentiation and invasion. Diseases associated with kinase activities include tumor growth, the pathologic neovascularization that supports solid tumor growth, and associated with other diseases where excessive local vascularization is involved such as ocular diseases (diabetic retinopathy, age-related macular degeneration, and the like) and inflammation (psoriasis, rheumatoid arthritis, and the like).

While not wishing to be bound to theory, phosphatases can also play a role in “kinase-dependent diseases or conditions” as cognates of kinases; that is, kinases phosphorylate and phosphatases dephosphorylate, for example protein substrates. Therefore compounds of the invention, while modulating kinase activity as described herein, may also modulate, either directly or indirectly, phosphatase activity. This additional modulation, if present, may be synergistic (or not) to activity of compounds of the invention toward a related or otherwise interdependent kinase or kinase family. In any case, as stated previously, the compounds of the invention are useful for treating diseases characterized in part by abnormal levels of cell proliferation (i.e. tumor growth), programmed cell death (apoptosis), cell migration and invasion and angiogenesis associated with tumor growth.

“Therapeutically effective amount” is an amount of a compound of the invention, that when administered to a patient, ameliorates a symptom of the disease. The amount of a compound of the invention which constitutes a “therapeutically effective amount” will vary depending on the compound, the disease state and its severity, the age of the patient to be treated, and the like. The therapeutically effective amount can be determined routinely by one of ordinary skill in the art having regard to their knowledge and to this disclosure.

Thus, the term “cancerous cell” as provided herein, includes a cell afflicted by any one of the above-identified conditions.

“Pharmaceutically acceptable acid addition salt” refers to those salts that retain the biological effectiveness of the free bases and that are not biologically or otherwise undesirable, formed with inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like, as well as organic acids such as acetic acid, trifluoroacetic acid, propionic acid, glycolic acid, pyruvic acid, oxalic acid, maleic acid, malonic acid, succinic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, salicylic acid and the like.

Exemplary salts are the ammonium, potassium, sodium, calcium, and magnesium salts. Salts derived from pharmaceutically acceptable organic non-toxic bases include, but are not limited to, salts of primary, secondary, and tertiary amines, substituted amines including naturally occurring substituted amines, cyclic amines and basic ion exchange resins, such as isopropylamine, trimethylamine, diethylamine, triethylarnine, tripropylamine, ethanolamine, 2-dimethylaminoethanol, 2-diethylaminoethanol, dicyclohexylamine, lysine, arginine, histidine, caffeine, procaine, hydrabamine, choline, betaine, ethylenediamine, glucosamine, methylglucamine, theobromine, purines, piperazine, piperidine, N-ethylpiperidine, polyamine resins, and the like. Exemplary organic bases are isopropylamine, diethylamine, ethanolamine, trimethylanine, dicyclohexylamine, choline, and caffeine. (See, for example, S. M. Berge, et al., “Pharmaceutical Salts,” J. Pharm. Sci., 1977;66:1-19 which is incorporated herein by reference.).

“Metabolite” refers to the break-down or end product of a compound or its salt produced by metabolism or biotransformation in the animal or human body; for example, biotransformation to a more polar molecule such as by oxidation, reduction, or hydrolysis, or to a conjugate (see Goodman and Gilman, “The Pharmacological Basis of Therapeutics” 8th Ed., Pergamon Press, Gilman et al. (eds), 1990 for a discussion of biotransformation). As used herein, the metabolite of a compound of the invention or its salt may be the biologically active form of the compound in the body. In one example, a prodrug may be used such that the biologically active form, a metabolite, is released in vivo. In another example, a biologically active metabolite is discovered serendipitously, that is, no prodrug design per se was undertaken. An assay for activity of a metabolite of a compound of the present invention is known to one of skill in the art in light of the present disclosure.

In addition, the compounds of the present invention can exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like. In general, the solvated forms are considered equivalent to the unsolvated forms for the purposes of the present invention.

In addition, it is intended that the present invention cover compounds made either using standard organic synthetic techniques, including combinatorial chemistry or by biological methods, such as bacterial digestion, metabolism, enzymatic conversion, and the like.

“Treating” or “treatment” as used herein covers the treatment of a disease-state in a human, which disease-state is characterized by abnormal cellular proliferation, and invasion and includes at least one of: (i) preventing the disease-state from occurring in a human, in particular, when such human is predisposed to the disease-state but has not yet been diagnosed as having it; (ii) inhibiting the disease-state, i.e., arresting its development; and (iii) relieving the disease-state, i.e., causing regression of the disease-state. As is known in the art, adjustments for systemic versus localized delivery, age, body weight, general health, sex, diet, time of administration, drug interaction and the severity of the condition may be necessary, and will be ascertainable with routine experimentation by one of ordinary skill in the art.

One of ordinary skill in the art would understand that certain crystallized, protein-ligand complexes, in particular IRK, IGF1R, c-Met, c-Kit, KDR, flt-3, or flt-4-ligand complexes, and their corresponding x-ray structure coordinates can be used to reveal new structural information useful for understanding the biological activity of kinases as described herein. As well, the key structural features of the aforementioned proteins, particularly, the shape of the ligand binding site, are useful in methods for designing or identifying selective modulators of kinases and in solving the structures of other proteins with similar features. Such protein-ligand complexes, having compounds of the invention as their ligand component, are an embodiment of the invention.

As well, one of ordinary skill in the art would appreciate that such suitable x-ray quality crystals can be used as part of a method of identifying a candidate agent capable of binding to and modulating the activity of kinases. Such methods may be characterized by the following embodiments: a) introducing into a suitable computer program, information defining a ligand binding domain of a kinase in a conformation (e.g. as defined by x-ray structure coordinates obtained from suitable x-ray quality crystals as described above) wherein the computer program creates a model of the three dimensional structures of the ligand binding domain, b) introducing a model of the three dimensional structure of a candidate agent in the computer program, c) superimposing the model of the candidate agent on the model of the ligand binding domain, and d) assessing whether the candidate agent model fits spatially into the ligand binding domain. Embodiments a-d are not necessarily carried out in the aforementioned order. Such methods may further entail: performing rational drug design with the model of the three-dimensional structure, and selecting a potential candidate agent in conjunction with computer modeling.

Additionally, one skilled in the art would appreciate that such methods may further entail: employing a candidate agent, so-determined to fit spatially into the ligand binding domain, in a biological activity assay for kinase modulation, and determining whether said candidate agent modulates kinase activity in the assay. Such methods may also include administering the candidate agent, determined to modulate kinase activity, to a mammal suffering from a condition treatable by kinase modulation, such as those described above.

Also, one skilled in the art would appreciate that compounds of the invention can be used in a method of evaluating the ability of a test agent to associate with a molecule or molecular complex comprising a ligand binding domain of a kinase. Such a method may be characterized by the following embodiments: a) creating a computer model of a kinase binding pocket using structure coordinates obtained from suitable x-ray quality crystals of the kinase, b) employing computational algorithms to perform a fitting operation between the test agent and the computer model of the binding pocket, and c) analyzing the results of the fitting operation to quantify the association between the test agent and the computer model of the binding pocket.

In the case of capsules, tablets, and pills, the dosage forms may also comprise buffering agents.

Solid dosage forms as described above can be prepared with coatings and shells, such as enteric coatings and others well known in the art. They may contain pacifying agents, and can also be of such composition that they release the active compound or compounds in a certain part of the intestinal tract in a delayed manner. Examples of embedded compositions that can be used are polymeric substances and waxes. The active compounds can also be in microencapsulated form, if appropriate, with one or more of the above-mentioned excipients.

Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs. Such dosage forms are prepared, for example, by dissolving, dispersing, etc., a compound(s) of the invention, or a pharmaceutically acceptable salt thereof, and optional pharmaceutical adjuvants in a carrier, such as, for example, water, saline, aqueous dextrose, glycerol, ethanol and the like; solubilizing agents and emulsifiers, as for example, ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propyleneglycol, 1,3-butyleneglycol, dimethylformamide; oils, in particular, cottonseed oil, groundnut oil, corn germ oil, olive oil, castor oil and sesame oil, glycerol, tetrahydrofurfuryl alcohol, polyethyleneglycols and fatty acid esters of sorbitan; or mixtures of these substances, and the like, to thereby form a solution or suspension.

Suspensions, in addition to the active compounds, may contain suspending agents, as for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, or mixtures of these substances, and the like.

Compositions for rectal administrations are, for example, suppositories that can be prepared by mixing the compounds of the present invention with for example suitable non-irritating excipients or carriers such as cocoa butter, polyethyleneglycol or a suppository wax, which are solid at ordinary temperatures but liquid at body temperature and therefore, melt while in a suitable body cavity and release the active component therein.

Dosage forms for topical administration of a compound of this invention include ointments, powders, sprays, and inhalants. The active component is admixed under sterile conditions with a physiologically acceptable carrier and any preservatives, buffers, or propellants as may be required. Ophthalmic Formulations, eye ointments, powders, and solutions are also contemplated as being within the scope of this invention.

Generally, depending on the intended mode of administration, the pharmaceutically acceptable compositions will contain about 1% to about 99% by weight of a compound(s) of the invention, or a pharmaceutically acceptable salt thereof, and 99% to 1% by weight of a suitable pharmaceutical excipient. In one example, the composition will be between about 5% and about 75% by weight of a compound(s) of the invention, or a pharmaceutically acceptable salt thereof, with the rest being suitable pharmaceutical excipients.

Actual methods of preparing such dosage forms are known, or will be apparent, to those skilled in this art; for example, see Remington's Pharmaceutical Sciences, 18th Ed., (Mack Publishing Company, Easton, Pa., 1990). The composition to be administered will, in any event, contain a therapeutically effective amount of a compound of the invention, or a pharmaceutically acceptable salt thereof, for treatment of a disease-state in accordance with the teachings of this invention.

The compounds of the invention, or their pharmaceutically acceptable salts, are administered in a therapeutically effective amount which will vary depending upon a variety of factors including the activity of the specific compound employed, the metabolic stability and length of action of the compound, the age, body weight, general health, sex, diet, mode and time of administration, rate of excretion, drug combination, the severity of the particular disease-states, and the host undergoing therapy. The compounds of the present invention can be administered to a patient at dosage levels in the range of about 0.1 to about 1,000 mg per day. For a normal human adult having a body weight of about 70 kilograms, a dosage in the range of about 0.01 to about 100 mg per kilogram of body weight per day is an example. The specific dosage used, however, can vary. For example, the dosage can depend on a number of factors including the requirements of the patient, the severity of the condition being treated, and the pharmacological activity of the compound being used. The determination of optimum dosages for a particular patient is well known to one of ordinary skill in the art.

General Synthetic Section

The compounds of the invention, or their pharmaceutically acceptable salts, may have asymmetric carbon atoms or quaternized nitrogen atoms in their structure.

It is assumed that when considering generic descriptions of compounds of the invention for the purpose of constructing a compound, such construction results in the creation of a stable structure. That is, one of ordinary skill in the art would recognize that theoretically some constructs which would not normally be considered as stable compounds (that is, sterically practical and/or synthetically feasible, supra).

The compounds of the invention and their pharmaceutically acceptable salts may exist as single stereoisomers, racemates, and as mixtures of enantiomers and diastereomers. The compounds may also exist as geometric isomers. All such single stereoisomers, racemates and mixtures thereof, and geometric isomers are intended to be within the scope of this invention.

Methods for the preparation and/or separation and isolation of single stereoisomers from racemic mixtures or non-racemic mixtures of stereoisomers are well known in the art. For example, optically active (R)- and (S)-isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. Enantiomers (R- and S-isomers) may be resolved by methods known to one of ordinary skill in the art, for example by: formation of diastereoisomeric salts or complexes which may be separated, for example, by crystallization; via formation of diastereoisomeric derivatives which may be separated, for example, by crystallization, selective reaction of one enantiomer with an enantiomer-specific reagent, for example enzymatic oxidation or reduction, followed by separation of the modified and unmodified enantiomers; or gas-liquid or liquid chromatography in a chiral environment, for example on a chiral support, such as silica with a bound chiral ligand or in the presence of a chiral solvent. It will be appreciated that where a desired enantiomer is converted into another chemical entity by one of the separation procedures described above, a further step may be required to liberate the desired enantiomeric form. Alternatively, specific enantiomer may be synthesized by asymmetric synthesis using optically active reagents, substrates, catalysts or solvents or by converting on enantiomer to the other by asymmetric transformation. For a mixture of enantiomers, enriched in a particular enantiomer, the major component enantiomer may be further enriched (with concomitant loss in yield) by recrystallization.

In addition, the compounds of the present invention can exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like. In general, the solvated forms are considered equivalent to the unsolvated forms for the purposes of the present invention.

In addition, it is intended that the present invention cover compounds made either using standard organic synthetic techniques, including combinatorial chemistry or by biological methods, such as bacterial digestion, metabolism, enzymatic conversion, and the like.

Section I Definitions

As used in this section, the following words and phrases are generally intended to have the meanings as set forth below, except to the extent that the context in which they are used indicates otherwise or they are expressly defined to mean something different.

The symbol “—” means a single bond, “═” means a double bond, “≡” means a triple bond, and means a single bond and optionally a double bond. When chemical structures are depicted or described, unless explicitly stated otherwise, all carbons are assumed to have hydrogen substitution to conform to a valence of four. Sometimes a particular atom in a structure is described in textual Formula as having a hydrogen or hydrogens as substitution (expressly defined hydrogen), for example, —CH2CH2—. It is understood by one of ordinary skill in the art that the aforementioned descriptive techniques are common in the chemical arts to provide brevity and simplicity to description of otherwise complex structures.

“Alkyl” or “lower alkyl” means a (C1-C20) linear, branched, or cyclic hydrocarbon group and combinations thereof, inclusively. For example, “C8 alkyl” refers to an n-octyl, iso-octyl, cyclohexylethyl, isobutenyl, and but-2-ynyl groups and the like. Examples of lower alkyl groups include methyl, ethyl, propyl, isopropyl, butyl, s-butyl, t-butyl, isobutyl, pentyl, hexyl and the like. Exemplary alkyl groups are those of C20 or below.

In this application, alkyl includes alkanyl, alkenyl, alkynyl, and cycloalkyl residues (and combinations thereof); it is intended to include cyclohexylmethyl, vinyl, allyl, isoprenyl, and the like. Thus when an alkyl residue having a specific number of carbons is named, all geometric isomers having that number of carbons are intended to be encompassed; thus, for example, either “butyl” or “C4 alkyl” is meant to include n-butyl, sec-butyl, isobutyl, t-butyl, isobutenyl and but-2-ynyl groups; and for example, “propyl” or “C3 alkyl” each include n-propyl, propenyl, and isopropyl.

It should additionally be noted that saturated carbons of such fused groups (i.e. saturated ring structures) can contain two substitution groups.

“Fused-polycyclic” or “fused ring system” means a polycyclic ring system that contains bridged or fused rings; that is, where two rings have more than one shared atom in their ring structures. In this application, fused-polycyclics and fused ring systems are not necessarily all aromatic ring systems. Typically, but not necessarily, fused-polycyclics share a vicinal set of atoms, for example naphthalene or 1,2,3,4-tetrahydro-naphthalene. A spiro ring system is not a fused-polycyclic by this definition, but fused polycyclic ring systems of the invention may themselves have spiro rings attached thereto via a single ring atom of the fused-polycyclic.

“Halogen” or “halo” means fluoro, chloro, bromo or iodo.

“Haloalkyl” and “haloaryl” mean an alkyl and an aryl group, respectively, that are substituted with one or more halogens, preferably one to five halo atoms. Thus, “dihaloaryl,” “dihaloalkyl,” and “trihaloaryl” etc. refer to aryl and alkyl substituted with a plurality of halogens, but not necessarily a plurality of the same halogen; thus 4-chloro-3-fluorophenyl is within the scope of dihaloaryl.

“Heteroatom” refers to O, S, N, or P.

“Heterocyclyl” means a stable three- to fifteen-membered ring substituent that consists of carbon atoms and from one to five heteroatoms selected from the group consisting of nitrogen, phosphorus, oxygen and sulfur. For purposes of this invention, the heterocyclyl substituent may be a monocyclic, bicyclic or tricyclic ring system, which may include fused or bridged ring systems as well as spirocyclic systems. The terms “heterocycloalkyl” and “heteroaryl” are groups that are encompassed by the broader term “heterocyclyl.” The nitrogen, phosphorus, carbon and sulfur atoms in the heterocyclyl group may be optionally oxidized to various oxidation states. In a specific example, the group —S(O)0-2—, refers to —S— (sulfide), —S(O)— (sulfoxide), and —SO2— (sulfone). For convenience, nitrogens, particularly but not exclusively, those defined as annular aromatic nitrogens, are meant to include their corresponding N-oxide form, although not explicitly defined as such in a particular example. Thus, for a compound of the invention having, for example, a pyridyl ring; the corresponding pyridyl-N-oxide is meant to be included as another compound of the invention. In addition, annular nitrogen atoms may be optionally quaternized; and the ring substituent may be partially or fully saturated or aromatic. Examples of heterocyclyl groups include, but are not limited to, azetidinyl, acridinyl, benzodioxolyl, benzodioxanyl, benzofuranyl, carbazoyl, cinnolinyl, dioxolanyl, indolizinyl, naphthyridinyl, perhydroazepinyl, phenazinyl, phenothiazinyl, phenoxazinyl, phthalazinyl, pteridinyl, purinyl, quinazolinyl, quinoxalinyl, quinolinyl, isoquinolinyl, tetrazoyl, tetrahydroisoquinolyl, piperidinyl, piperazinyl, 2-oxopiperazinyl, 2-oxopiperidinyl, 2-oxopyrrolidinyl, 2-oxoazepinyl, azepinyl, pyrrolyl, 4-piperidonyl, pyrrolidinyl, pyrazolyl, pyrazolidinyl, imidazolyl, imidazolinyl, imidazolidinyl, dihydropyridinyl, tetrahydropyridinyl, pyridinyl, pyrazinyl, pyrimidinyl, pyridazinyl, oxazolyl, oxazolinyl, oxazolidinyl, triazolyl, isoxazolyl, isoxazolidinyl, morpholinyl, thiazolyl, thiazolinyl, thiazolidinyl, isothiazolyl, quinuclidinyl, isothiazolidinyl, indolyl, isoindolyl, indolinyl, isoindolinyl, octahydroindolyl, octahydroisoindolyl, quinolyl, isoquinolyl, decahydroisoquinolyl, benzimidazolyl, thiadiazolyl, benzopyranyl, benzothiazolyl, benzoxazolyl, furyl, tetrahydrofuiryl, tetrahydropyranyl, thienyl, benzothienyl, thiamorpholinyl, thiamorpholinyl sulfoxide, thiamorpholinyl sulfone, dioxaphospholanyl, and oxadiazolyl.

Additionally, for simplicity, the number of annular atoms (including heteroatoms) in a heterocycle may be denoted as “Cx-Cy” (as in “Cx-Cy-heterocyclyl” and “Cx-Cy-heteroaryl” (and the like)), where x and y are integers. So, for example, C5-C14-heterocyclyl refers to a 5 to 14 membered ring system having at least one heteroatom and not a ring system containing 5 to 14 annular carbon atoms.

“Optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. One of ordinary skill in the art would understand that with respect to any molecule described as containing one or more optional substituents, only sterically practical and/or synthetically feasible compounds are meant to be included. “Optionally substituted” refers to all subsequent modifiers in a term. So, for example, in the term “optionally substituted arylC1-8 alkyl,” both the “C1-8 alkyl” portion and the “aryl” portion of the molecule may or may not be substituted.

For example, as depicted below, a ring atom of a saturated bridged ring system (rings B and B′), but not a bridgehead atom, can be a shared atom between the saturated bridged ring system and a spirocyclyl (ring A) attached thereto. A spirocyclyl can be carbocyclic or heteroalicyclic.

Section II Definitions

As used in the present specification, the following words and phrases are generally intended to have the meanings as set forth below, except to the extent that the context in which they are used indicates otherwise or they are expressly defined to mean something different.

The symbol “—” means a single bond, “═” means a double bond, “≡” means a triple bond, means a single or double bond. The symbol to a group on a double-bond as occupying either position on the terminus of a double bond to which the symbol is attached; that is, the geometry, E- or Z-, of the double bond is ambiguous. When a group is depicted removed from its parent formula, the symbol will be used at the end of the bond which was theoretically cleaved in order to separate the group from its parent structural formula.

When chemical structures are depicted or described, unless explicitly stated otherwise, all carbons are assumed to have hydrogen substitution to conform to a valence of four. For example, in the structure on the left-hand side of the schematic below there are nine hydrogens implied. The nine hydrogens are depicted in the right-hand structure. Sometimes a particular atom in a structure is described in textual formula as having a hydrogen or hydrogens as substitution (expressly defined hydrogen), for example, —CH2CH2—. It is understood by one of ordinary skill in the art that the aforementioned descriptive techniques are common in the chemical arts to provide brevity and simplicity to description of otherwise complex structures.

If a group “R” is depicted as “floating” on a ring system, as for example in the formula:

then, unless otherwise defined, a substituent “R” may reside on any atom of the ring system, assuming replacement of a depicted, implied, or expressly defined hydrogen from one of the ring atoms, so long as a stable structure is formed.

If a group “R” is depicted as floating on a fused ring system, as for example in the formulae:

then, unless otherwise defined, a substituent “R” may reside on any atom of the fused ring system, assuming replacement of a depicted hydrogen (for example the —NH— in the formula above), implied hydrogen (for example as in the formula above, where the hydrogens are not shown but understood to be present), or expressly defined hydrogen (for example where in the formula above, “X” equals ═CH—) from one of the ring atoms, so long as a stable structure is formed. In the example depicted, the “R” group may reside on either the 5-membered or the 6-membered ring of the fused ring system. In the formula depicted above, when y is 2 for example, then the two “R's” may reside on any two atoms of the ring system, again assuming each replaces a depicted, implied, or expressly defined hydrogen on the ring.

When a group “R” is depicted as existing on a ring system containing saturated carbons, as for example in the formula:

where, in this example, “y” can be more than one, assuming each replaces a currently depicted, implied, or expressly defined hydrogen on the ring; then, unless otherwise defined, where the resulting structure is stable, two “R's” may reside on the same carbon. A simple example is when R is a methyl group; there can exist a geminal dimethyl on a carbon of the depicted ring (an “annular” carbon). In another example, two R's on the same carbon, including that carbon, may form a ring, thus creating a spirocyclic ring (a “spirocyclyl” group) structure with the depicted ring as for example in the formula:

“Alkyl” is intended to include linear or branched hydrocarbon structures and combinations thereof, inclusively. For example, “C8 alkyl” may refer to an n-octyl, iso-ctyl, and the like. Lower alkyl refers to alkyl groups of from one to six carbon atoms. Examples of lower alkyl groups include methyl, ethyl, propyl, isopropyl, butyl, s-butyl, t-utyl, isobutyl, pentyl, and the like. Higher alkyl refers to alkyl groups containing more that eight carbon atoms. A “C0” alkyl (as in “C0-C6-alkyl”) is a covalent bond. Exemplary alkyl groups are those of C20 or below. In this application, alkyl refers to alkanyl, alkenyl, and alkynyl residues (and combinations thereof); it is intended to include vinyl, allyl, isoprenyl, and the like. Thus when an alkyl residue having a specific number of carbons is named, all geometric isomers having that number of carbons are intended to be encompassed; thus, for example, either “butyl” or “C4 alkyl” is meant to include n-butyl, sec-butyl, isobutyl, t-butyl, isobutenyl and but-2-ynyl groups; and for example, “propyl” or “C3 alkyl” each include n-propyl, propenyl, and isopropyl.

“Cycloalkyl” means a cyclic hydrocarbon groups of from three to thirteen carbon atoms. Examples of cycloalkyl groups include c-propyl, c-butyl, c-pentyl, norbornyl, adamantyl and the like.

“Alkoxy” or “alkoxyl” refers to the group —O-alkyl, for example including from one to eight carbon atoms of a straight, branched, cyclic configuration, unsaturated chains, and combinations thereof attached to the parent structure through an oxygen atom. Examples include methoxy, ethoxy, propoxy, isopropoxy, cyclopropyloxy, cyclohexyloxy and the like. Lower-alkoxy refers to groups containing one to six carbons.

“Optionally substituted alkoxy” refers to the group —OR where R is optionally substituted alkyl, as defined herein. One exemplary substituted alkoxy group is “polyalkoxy” or —O-optionally substituted alkylene-optionally substituted alkoxy, and includes groups such as —OCH2CH2OCH3, and glycol ethers such as polyethyleneglycol and —O(CH2CH2O)xCH3, where x is an integer of between about two and about twenty, in another example, between about two and about ten, and in a further example between about two and about five. Another exemplary substituted alkoxy group is hydroxyalkoxy or —OCH2(CH2)yOH, where y is for example an integer of between about one and about ten, in another example y is an integer of between about one and about four.

“Acyl” refers to groups of from one to ten carbon atoms of a straight, branched, cyclic configuration, saturated, unsaturated and aromatic and combinations thereof, attached to the parent structure through a carbonyl functionality. One or more carbons in the acyl residue may be replaced by nitrogen, oxygen or sulfur as long as the point of attachment to the parent remains at the carbonyl. Examples include acetyl, benzoyl, propionyl, isobutyryl, t-butoxycarbonyl, benzyloxycarbonyl and the like. Lower-acyl refers to groups containing one to six carbons.

“Acyloxy” means an —OR group where R is acyl as defined herein.

“Acylamino” means an —NHR group where R is acyl as defined herein.

“Amino” refers to the group —NH2. “Substituted amino,” refers to the group —N(H)R or —(R)R where each R is independently selected from the group: optionally substituted alkyl, optionally substituted alkoxy, optionally substituted aryl, optionally substituted heterocyclyl, acyl, carboxy, alkoxycarbonyl, sulfanyl, sulfinyl and sulfonyl, for example, diethylamino, methylsulfonylamino, and furanyl-oxy-sulfonamino.

“Aryl” refers to aromatic six- to fourteen-membered carbocyclic ring, for example, benzene, naphthalene, indane, tetralin, fluorene and the like, univalent substituents. As univalent substituents, the aforementioned ring examples are named, phenyl, naphthyl, indanyl, tetralinyl, and fluorenyl.

“Arylalkyl” refers to a residue in which an aryl moiety is attached to a parent structure via one of an alkylene, alkylidene, or alkylidyne group. Examples include benzyl, phenethyl, phenylvinyl, phenylallyl and the like. Both the aryl and the corresponding alkylene, alkylidene, or alkylidyne group portion of an arylalkyl group may be optionally substituted. “Lower arylalkyl” refers to an arylalkyl where the “alkyl” portion of the group has one to six carbons; this can also be referred to as C1-6 arylalkyl.

In some examples, as appreciated by one of ordinary skill in the art, two adjacent groups on an aromatic system may be fused together to form a ring structure. The fused ring structure may contain heteroatoms and may be optionally substituted with one or more groups. It should additionally be noted that saturated carbons of such fused groups (i.e. saturated ring structures) can contain two substitution groups.

“Halogen” or “halo” refers to fluorine, chlorine, bromine or iodine.

“Haloalkyl” and “haloaryl” refer generically to alkyl and aryl groups that are substituted with one or more halogens, respectively. Thus, “dihaloaryl,” “dihaloalkyl,” “trihaloaryl” etc. refer to aryl and alkyl substituted with a plurality of halogens, but not necessarily a plurality of the same halogen; thus 4-chloro-3-fluorophenyl is within the scope of dihaloaryl. Haloalkyl includes, for instance, mono- to per-haloC1-C6 alkyl.

“Heteroatom” refers to O, S, N, or P.

“Heterocyclyl” refers to a stable three- to fifteen-membered ring substituent that consists of carbon atoms and from one to five heteroatoms selected from the group consisting of nitrogen, phosphorus, oxygen and sulfur. For purposes of this invention, the heterocyclyl substituent may be a monocyclic, bicyclic or tricyclic ring system, which may include fused or bridged ring systems as well as spirocyclic systems; and the nitrogen, phosphorus, carbon or sulfur atoms in the heterocyclyl group may be optionally oxidized to various oxidation states. In a specific example, the group —S(O)0-2—, refers to —S— (sulfide), —S(O)— (sulfoxide), and —SO2— (sulfone). For convenience, nitrogens, particularly but not exclusively, those defined as annular aromatic nitrogens, are meant to include their corresponding N-oxide form, although not explicitly defined as such in a particular example. Thus, for a compound of the invention having, for example, a pyridyl ring; the corresponding pyridyl-N-oxide is meant to be included as another compound of the invention. In addition, annular nitrogen atoms may be optionally quaternized; and the ring substituent may be partially or fully saturated or aromatic. Examples of heterocyclyl groups include, but are not limited to, azetidinyl, acridinyl, benzodioxolyl, benzodioxanyl, benzofuranyl, carbazoyl, cinnolinyl, dioxolanyl, indolizinyl, naphthyridinyl, perhydroazepinyl, phenazinyl, phenothiazinyl, phenoxazinyl, phthalazinyl, pteridinyl, purinyl, quinazolinyl, quinoxalinyl, quinolinyl, isoquinolinyl, tetrazoyl, tetrahydroisoquinolyl, piperidinyl, piperazinyl, 2-oxopiperazinyl, 2-oxopiperidinyl, 2-oxopyrrolidinyl, 2-oxoazepinyl, azepinyl, pyrrolyl, 4-piperidonyl, pyrrolidinyl, pyrazolyl, pyrazolidinyl, imidazolyl, imidazolinyl, imidazolidinyl, dihydropyridinyl, tetrahydropyridinyl, pyridinyl, pyrazinyl, pyrimidinyl, pyridazinyl, oxazolyl, oxazolinyl, oxazolidinyl, triazolyl, isoxazolyl, isoxazolidinyl, morpholinyl, thiazolyl, thiazolinyl, thiazolidinyl, isothiazolyl, quinuclidinyl, isothiazolidinyl, indolyl, isoindolyl, indolinyl, isoindolinyl, octahydroindolyl, octahydroisoindolyl, quinolyl, isoquinolyl, decahydroisoquinolyl, benzimidazolyl, thiadiazolyl, benzopyranyl, benzothiazolyl, benzoxazolyl, furyl, tetrahydrofuryl, tetrahydropyranyl, thienyl, benzothienyl, thiamorpholinyl, thiamorpholinyl sulfoxide, thiamorpholinyl sulfone, dioxaphospholanyl, and oxadiazolyl.

“Heteroalicyclic” refers specifically to a non-aromatic heterocyclyl group. A heteroalicyclic may contain unsaturation, but is not aromatic.

“Heteroalicyclicalkyl” refers specifically to an alkyl group substituted with one or two non-aromatic heterocyclyl group. The heteroalicyclic ring portion of this group may contain unsaturation, but is not aromatic.

“Heteroaryl” refers specifically to an aromatic heterocyclyl group.

“Heterocyclylalkyl” refers to a residue in which a heterocyclyl is attached to a parent structure via one of an alkylene, alkylidene, or alkylidyne group. Examples include (4-methylpiperazin-1-yl) methyl, (morpholin-4-yl) methyl, (pyridine-4-yl) methyl, 2-(oxazolin-2-yl) ethyl, 4-(4-methylpiperazin-1-yl)-2-butenyl, and the like. Both the heterocyclyl and the corresponding alkylene, alkylidene, or alkylidyne portion of a heterocyclylalkyl group may be optionally substituted. “Lower heterocyclylalkyl” refers to a heterocyclylalkyl where the “alkyl” portion of the group has one to six carbons. “Heteroalicyclylalkyl” refers specifically to a heterocyclylalkyl where the heterocyclyl portion of the group is non-aromatic; and “heteroarylalkyl” refers specifically to a heterocyclylalkyl where the heterocyclyl portion of the group is aromatic Such terms may be described in more than one way, for example, “lower heterocyclylalkyl” and “heterocyclyl C1-6alkyl” are equivalent terms. Additionally, for simplicity, the number of annular atoms (including heteroatoms) in a heterocycle may be denoted as “Cx-Cy” (as in “Cx-Cy-heterocyclyl” and “Cx-Cy-heteroaryl” (and the like)), where x and y are integers. So, for example, C5-C14-heterocyclyl refers to a 5 to 14 membered ring system having at least one heteroatom and not a ring system containing 5 to 14 annular carbon atoms.

Preferred heterocyclyls and heteroaryls include, but are not limited to, acridinyl, azocinyl, benzimidazolyl, benzofuranyl, benzothiophenyl, benzoxazolyl, benzthiazolyl, benztriazolyl, pyridotriazolyl, benzisoxazolyl, benzisothiazolyl, benzimidazolinyl, carbazolyl, 4aH-carbazolyl, carbolinyl, chromanyl, chromenyl, cinnolinyl, decahydroquinolinyl, 2H,6H-1,5,2-dithiazinyl, dihydrofuro[2,3-b]tetrahydrofuran, furanyl, furazanyl, imidazolidinyl, imidazolinyl, imidazolyl, 1H-indazolyl, indolenyl, indolinyl, indolizinyl, indolyl, 3H-indolyl, isobenzofuranyl, isochromanyl, isoindazolyl, isoindolinyl, isoindolyl, isoquinolinyl, isothiazolyl, isoxazolyl, methylenedioxyphenyl, morpholinyl, naphthyridinyl, octahydroisoquinolinyl, oxadiazolyl, 1,2,3-oxadiazolyl, 1,2,4-oxadiazolyl, 1,2,5-oxadiazolyl, 1,3,4-oxadiazolyl, oxazolidinyl, oxazolyl, oxazolidinyl, pyrimidinyl, phenanthridinyl, phenanthrolinyl, phenazinyl, phenothiazinyl, phenoxathiinyl, phenoxazinyl, phthalazinyl, piperazinyl, piperidinyl, piperidonyl, 4-piperidonyl, piperonyl, pteridinyl, purinyl, pyranyl, pyrazinyl, pyrazolidinyl, pyrazolinyl, pyrazolyl, pyridazinyl, pyridooxazole, pyridoimidazole, pyridothiazole, pyridinyl, pyridyl, pyrimidinyl, pyrrolidinyl, pyrrolinyl, 2H-pyrrolyl, pyrrolyl, quinazolinyl, quinolinyl, 4H-quinolizinyl, quinoxalinyl, quinuclidinyl, tetrahydrofiranyl, tetrahydroisoquinolinyl, tetrahydroquinolinyl, tetrazolyl, 6H-1,2,5-thiadiazinyl, 1,2,3-thiadiazolyl, 1,2,4-thiadiazolyl, 1,2,5-thiadiazolyl, 1,3,4-thiadiazolyl, thianthrenyl, thiazolyl, thienyl, thienothiazolyl, thienooxazolyl, thienoimidazolyl, thiophenyl, triazinyl, 1,2,3-triazolyl, 1,2,4-triazolyl, 1,3,4-triazolyl, and xanthenyl.

“Heterocyclyl-aryl-” means an aryl group substituted with at least one, specifically 1 or 2 heterocyclyl, as defined herein. “Optionally substituted heterocyclyl-aryl-” means that either or both the aryl and the heterocyclyl can be substituted as defined in “substituted.”

“Optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. One of ordinary skill in the art would understand that with respect to any molecule described as containing one or more optional substituents, only sterically practical and/or synthetically feasible compounds are meant to be included. “Optionally substituted” refers to all subsequent modifiers in a term. So, for example, in the term “optionally substituted arylC1-8 alkyl,” optional substitution may occur on both the “C1-8 alkyl” portion and the “aryl” portion of the molecule may or may not be substituted. A list of exemplary optional substitutions is presented below in the definition of “substituted.”

“Saturated bridged ring system” refers to a bicyclic or polycyclic ring system that is not aromatic. Such a system may contain isolated or conjugated unsaturation, but not aromatic or heteroaromatic rings in its core structure (but may have aromatic substitution thereon). For example, hexahydro-furo[3,2-b]furan, 2,3,3a,4,7,7a-hexahydro-1H-indene, 7-aza-bicyclo[2.2.1]heptane, and 1,2,3,4,4a,5,8,8a-octahydro-naphthalene are all included in the class “saturated bridged ring system.

“Spirocyclyl” or “spirocyclic ring” refers to a ring originating from a particular annular carbon of another ring. For example, as depicted below, a ring atom of a saturated bridged ring system (rings B and B′), but not a bridgehead atom, can be a shared atom between the saturated bridged ring system and a spirocyclyl (ring A) attached thereto. A spirocyclyl can be carbocyclic or heteroalicyclic.

“Substituted” alkyl, cycloalkyl, aryl, and heterocyclyl (including heteroalicyclic and heteroaryl), refer respectively to alkyl, aryl, and heterocyclyl, where one or more (for example up to about five, in another example, up to about three) hydrogen atoms are replaced by a substituent. The substituent(s) on alkyl, aryl, heteroaryl, and heterocyclyl (including when any of these groups are part of another group, such as the alkyl portion of alkoxy, or the aryl portion of aryloxy) include, for instance, one or more groups selected from alkylenedioxy (for example methylenedioxy), aryloxy (for example, phenoxy), carboxy, acyloxy, acylamino, benzyloxycarbonylamino, acyl, carbamyl, oxo, hydroxy, halo, nitro, cyano, 'O—C1-C6 alkyl, haloalkyl, C1-C6 alkyl, cycloalkyl, —C(O)O—C1-C6 alkyl, —O—C1-C6 alkyl-aryl, —C1-C6 alkyl-aryl, —O—C1-C6 alkyl-O—C1-C6 alkyl, —N(Ra)(Rb), (Ra)(Rb)N—C1-C6 alkyl-, —O—C1-C6 alkyl-N(Ra)(Rb), —O—C1-C6 alkyl-heterocyclyl, C0-C6 alkyl-heterocyclyl, C0-C6 alkyl-aryl, C0-C6 alkyl-heteroaryl, —C(O)N(Ra)—C1-C6-alkyl-N(Ra)(Rb), sulfanyl, sulfinyl, sulfonyl, aryl, heteroaryl, heterocyclyl, arylalkyl-, heteroarylalkyl-, and heterocyclylalkyl, where Ra and Rb are independently hydrogen or alkyl, or Ra and Rb together with the nitrogen to which they are attached form a heterocyclyl group. Examples of heterocyclyl groups formed by Ra and Rb include morpholinyl and piperazinyl. Each substituent of a substituted group is optionally substituted, but these optional substituents themselves are not further substituted. Thus, an optionally substituted moiety is one that may or may not have one or more substituents, and each of the substituents may or may not have one or more substituents. But, the substituents of the substituents may not be substituted.

“Sulfanyl” refers to the groups: —S-(optionally substituted alkyl), —S-(optionally substituted aryl), and —S-(optionally substituted heterocyclyl).

“Sulfinyl” refers to the groups: —S(O)—H, —S(O)-(optionally substituted alkyl), —S(O)-optionally substituted aryl), and —S(O)-(optionally substituted heterocyclyl).

“Sulfonyl” refers to the groups: —S(O2)—H, —S(O2)-(optionally substituted alkyl), —S(O2)-optionally substituted aryl), —S(O2)-(optionally substituted heterocyclyl), —S(O2)-(optionally substituted alkoxy), —S(O2)-optionally substituted aryloxy), and —S(O2)-(optionally substituted heterocyclyloxy).

In Vitro Enzymatic Assay Description for Sections II and III:

PI3Kalpha Luciferase-Coupled Chemiluminescence Assay Protocol

PI3Kalpha activity is measured as the percent of ATP consumed following the kinase reaction using luciferase-luciferin-coupled chemiluminescence. Reactions were conducted in 384-well white, medium binding microtiter plates (Greiner). Kinase reactions were initiated by combining test compounds, ATP, substrate (PIP2), and kinase in a 20 μL volume. The standard assay concentrations for enzyme, ATP, and substrate are 1.1 nm, 1 μM, and 7.5 μM, respectively. The reaction mixture was incubated at ambient temperature for 2 h. Following the kinase reaction, a 10 μL aliquot of luciferase-luciferin mix (Promega Kinase-Glo) was added and the chemiluminescence signal measured using a Victor2 plate reader (Perkin Elmer). Total ATP consumption was limited to 40-60% and IC50 values of control compounds correlate well with literature references. In this assay, preferred compounds of the invention exhibit an IC50 of less than 50 micromolar. More preferred compounds of the invention exhibit an IC50 of less than I micromolar. Even more preferred compounds of the invention exhibit an IC50 of less than 500 nanomolar. Still more preferred compounds of the invention exhibit an IC50 of less than 250 nanomolar.

Cell Assay Descriptions:

Phospho AKT Assay

PC3 cells were seeded on 6-well plates at 150,000 cells/well. Cells were cultured for 3 days, then treated with compounds in serum-free medium for 3 hr. EGF (100 ng/ml) was added for the last 10 min. Cells were lysed in TENN buffer. Phospho T308 Akt and total Akt were quantified by ELISA performed according to the Biosource assay protocol. The readings of phospho Akt were normalized to total Akt readings.

Phospho S6 Assay

PC3 cells were seeded on 96-well plates at 8,000 cells/well. For each experiment, cells were seeded and treated in duplicated plates: one plate for phospho S6 CellELISA, and one plate for total S6 CellELISA. Cells were cultured on the plates for 3 days, then treated with compounds in serum-free medium for 3 hr in triplicate. Cells were fixed with 4% formaldehyde, quenched with 0.6% H2O2, blocked with 5% BSA, incubated with either phospho S6 antibody or total S6 antibody overnight, incubated with goat-anti-rabbit-IgG-HRP for 1 hr, and developed in chemiluminescent substrate.

PIP3 Assay

MCF-7 cells grown in 10-cm dishes were starved for 3 hours in DMEM, and then treated with compounds for 20 minutes. In the last 2 minutes of the incubation with the compounds, EGF (100 ng/ml) was added to stimulate the production of PIP3. The medium was aspirated and the cells were scraped with 10% trichloroacetic acid. The lipids were extracted from the pellet after the cell lysates were centrifuged. PIP3 in the cellular lipid extraction was quantified with the AlpbaScreen assay in which Grp1-PH is used as the PIP3 specific probe. The amount of cellular PIP3 was calculated from the standard curve of diC8 PI (3,4,5) P3.

Another embodiment of the invention is directed to suitable x-ray quality crystals, and one of ordinary skill in the art would appreciate that they can be used as part of a method of identifying a candidate agent capable of binding to and modulating the activity of kinases. Such methods may be characterized by the following embodiments: a) introducing into a suitable computer program, information defining a ligand binding domain of a kinase in a conformation (e.g. as defined by x-ray structure coordinates obtained from suitable x-ray quality crystals as described above) wherein the computer program creates a model of the three dimensional structures of the ligand binding domain, b) introducing a model of the three dimensional structure of a candidate agent in the computer program, c) superimposing the model of the candidate agent on the model of the ligand binding domain, and d) assessing whether the candidate agent model fits spatially into the ligand binding domain. Embodiments a-d are not necessarily carried out in the aforementioned order. Such methods may further entail: performing rational drug design with the model of the three-dimensional structure, and selecting a potential candidate agent in conjunction with computer modeling.

Additionally, one skilled in the art would appreciate that such methods may further entail: employing a candidate agent, so-determined to fit spatially into the ligand binding domain, in a biological activity assay for kinase modulation, and determining whether said candidate agent modulates kinase activity in the assay. Such methods may also include administering the candidate agent, determined to modulate kinase activity, to a mammal suffering from a condition treatable by kinase modulation, such as those described above.

Also, one skilled in the art would appreciate that compounds of the invention can be used in a method of evaluating the ability of a test agent to associate with a molecule or molecular complex comprising a ligand binding domain of a kinase. Such a method may be characterized by the following embodiments: a) creating a computer model of a kinase binding pocket using structure coordinates obtained from suitable x-ray quality crystals of the kinase, b) employing computational algorithms to perform a fitting operation between the test agent and the computer model of the binding pocket, and c) analyzing the results of the fitting operation to quantify the association between the test agent and the computer model of the binding pocket.

Section III Definitions

As used in the present specification, the following words and phrases are generally intended to have the meanings as set forth below, except to the extent that the context in which they are used indicates otherwise or they are expressly defined to mean something different.

The symbol “—” means a single bond, “═” means a double bond, “≡” means a triple bond, means a single or double bond. When a group is depicted removed from its parent Formula, the symbol will be used at the end of the bond which was theoretically cleaved in order to separate the group from its parent structural Formula.

When chemical structures are depicted or described, unless explicitly stated otherwise, all carbons are assumed to have hydrogen substitution to conform to a valence of four. For example, in the structure on the left-hand side of the schematic below there are nine hydrogens implied. The nine hydrogens are depicted in the right-hand structure. Sometimes a particular atom in a structure is described in textual Formula as having a hydrogen or hydrogens as substitution (expressly defined hydrogen), for example, —CH2CH2—. It is understood by one of ordinary skill in the art that the aforementioned descriptive techniques are common in the chemical arts to provide brevity and simplicity to description of otherwise complex structures.

If a group “R” is depicted as “floating” on a ring system, as for example in the Formula:

then, unless otherwise defined, a substituent “R” may reside on any atom of the ring system, assuming replacement of a depicted, implied, or expressly defined hydrogen from one of the ring atoms, so long as a stable structure is formed.

If a group “R” is depicted as floating on a fused ring system, as for example in the Formulae:

then, unless otherwise defined, a substituent “R” may reside on any atom of the fused ring system, assuming replacement of a depicted hydrogen (for example the —NH— in the Formula above), implied hydrogen (for example as in the Formula above, where the hydrogens are not shown but understood to be present), or expressly defined hydrogen (for example where in the Formula above, “X” equals ═CH—) from one of the ring atoms, so long as a stable structure is formed. In the example depicted, the “R” group may reside on either the 5-membered or the 6-membered ring of the fused ring system. In the Formula depicted above, when y is 2 for example, then the two “R's” may reside on any two atoms of the ring system, again assuming each replaces a depicted, implied, or expressly defined hydrogen on the ring.

When a group “R” is depicted as existing on a ring system containing saturated carbons, as for example in the Formula:

where, in this example, “y” can be more than one, assuming each replaces a currently depicted, implied, or expressly defined hydrogen on the ring; then, unless otherwise defined, where the resulting structure is stable, two “R's” may reside on the same carbon. A simple example is when R is a methyl group; there can exist a geminal dimethyl on a carbon of the depicted ring (an “annular” carbon). In another example, two R's on the same carbon, including that carbon, may form a ring, thus creating a spirocyclic ring (a “spirocyclyl” group) structure with the depicted ring as for example in the Formula:

“Acyl” means a —C(O)R radical where R is alkyl (i.e., one to ten carbon atoms of a straight, branched, or cyclic configuration, and is saturated or unsaturated) or R is optionally substituted aryl or optionally substituted heteroaryl. One or more carbons in the R residue may be replaced by nitrogen, oxygen or sulfur. Examples include acetyl, benzoyl, propionyl, isobutyryl, t-butoxycarbonyl, benzyloxycarbonyl, and pyridinylcarbonyl, and the like. Lower-acyl refers to groups containing one to six carbons.

“Acylarnino” means a —NRR′ group where R is acyl, as defined herein, and R′ is hydrogen or alkyl.

“Alkyl” means a (C1-C20) linear, branched, or cyclic hydrocarbon group (and combinations thereof, inclusively) and may be saturated or unsaturated. For example, “C6 alkyl” may refer to an n-hexyl, iso-hexyl, cyclobutylethyl, and the like. “Lower alkyl” means an alkyl group of from one to six carbon atoms. Examples of lower alkyl groups include methyl, ethyl, propyl, isopropyl, butyl, s-butyl, t-butyl, isobutyl, pentyl, hexyl and the like. A “C0” alkyl (as in “C0-C6-alkyl”) is a covalent bond.

In this application, alkyl includes alkanyl, alkenyl, alkynyl, and cycloalkyl residues (and combinations thereof); it is intended to include cyclohexylmethyl, vinyl, allyl, isoprenyl, and the like. Thus when an alkyl residue having a specific number of carbons is named, all geometric isomers having that number of carbons are intended to be encompassed; thus, for example, “C4 alkyl” is meant to include n-butyl, sec-butyl, isobutyl, t-butyl, cyclobutyl, isobutenyl and but-2-ynyl groups; and for example, “C3 alkyl” each include n-propyl, propenyl, and isopropyl.

“Alkanyl” means a linear saturated monovalent hydrocarbon radical of one to twenty carbon atoms or a branched saturated monovalent hydrocarbon radical of three to 20 carbon atoms, e.g., methyl, ethyl, propyl, 2-propyl, butyl (including all isomeric forms), or pentyl (including all isomeric forms), and the like. “Lower alkanyl” means alkanyl having one to six carbons atoms.

“Cycloalkyl” means a monocyclic or polycyclic hydrocarbon radical having three to thirteen carbon atoms. The cycloalkyl can be saturated or partially unsaturated, but cannot contain an aromatic ring. Cycloalkyl includes fused, bridged, and spiro ring systems. Examples of such radicals include cyclopropyl, cyclobutyl, cyclopentyl and cyclohexyl. “Cycloalkylalkyl” means alkyl group substituted with one or two cycloalkyl group(s), as defined herein. Representative examples include cyclopropylmethyl and 2-cyclobutyl-ethyl, and the like.

“Optionally substituted cycloalkyl” means a cycloalkyl radical, as defined herein, that is optionally substituted with one, two, three, or four groups independently selected from C1-C6 alkanyl, C1-C6 alkoxy, halo, haloalkyl, haloalkoxy, oxo, hydroxy, cyano, nitro, amino, mono(C1-C6)alkylamino, di(C1-C6)alkylamino, C2-C6alkenyl, C2-C6alkynyl, C1-C6 haloalkyl, C1-C6 haloalkoxy, amino(C1-C6)alkyl, mono(C1-C6)alkylamino(C1-C6)alkyl di(C1-C6)alkylamino(C1-C6)alkyl, carboxy, carboxy ester, cycloalkyl, hydroxyalkyl, —C(O)NR′R″ (where R′ is hydrogen, alkyl, hydroxy, or alkoxy and R″ is hydrogen, alkyl, aryl, or heterocyclyl), optionally substituted heterocycloalkyl, optionally substituted heteroaryl, —NR′C(O)R″ (where R′ is hydrogen or alkyl and R″ is alkyl, aryl, or heterocyclyl), and —NHS(O)2R′ (where R′ is alkyl, aryl, or hetercyclyl).

“Alkenyl” means a straight or branched hydrocarbon radical having from 2 to 20 carbon atoms and at least one double bond and includes ethenyl, propenyl, 1-but-3-enyl, 1-pent-3-enyl, 1-hex-5-enyl and the like. “Lower alkenyl” is alkenyl having 2-6 carbon atoms.

“Alkynyl” means a straight or branched hydrocarbon radical having from 2 to 20 carbon atoms and at least one triple bond and includes ethynyl, propynyl, butynyl, pentyn-2-yl and the like. “Lower alkynyl” is alkynyl having 2-6 carbon atoms.

“Alkylidyne” or “alkynylene” means a straight or branched divalent hydrocarbon having from two to ten carbon atoms, and containing at least one triple bond, for example, propylid-2-ynyl, n-butylid-1-ynyl, and the like.

“Alkoxy” or “alkoxyl” means —O-alkyl, where the alkyl group includes from one to eight carbon atoms of a straight, branched, cyclic configuration, unsaturated chains, and combinations thereof attached to the parent structure through an oxygen atom. Examples include metboxy, ethoxy, propoxy, isopropoxy, cyclopropyloxy, cyclohexyloxy and the like. Lower-alkoxy refers to groups containing one to six carbons.

“Alkylamino” means a —NHR radical where R is alkyl as defined herein, or an N-oxide derivative, or a protected derivative thereof, e.g., methylamino, ethylamino, n-, iso-propylamino, n-, iso-, tert-butylamino, or methylamino-N-oxide, and the like.

“Alkylaminoalkyl” means an alkyl group substituted with one or two alkylamino groups, as defined herein.

“Aryl” means a monovalent six- to fourteen-membered, mono- or bi-carbocyclic ring, wherein the monocyclic ring is aromatic and at least one of the rings in the bicyclic ring is aromatic. Representative examples include phenyl, naphthyl, and indanyl, and the like.

“Optionally substituted aryl” means an aryl group, as defined herein, which is optionally substituted with one, two, three, four, of five groups selected from halo, haloalkyl, haloalkoxy, hydroxy, lower alkanyl, lower alkenyl, lower alkynyl, alkoxy, carboxy, carboxy ester, amino, alkylamino, dialkylamino, optionally substituted cycloalkyl, optionally substituted heterocycloalkyi, optionally substituted heteroaryl, —C(O)NR′R″ (where R′ is hydrogen or alkyl and R″ is hydrogen, alkyl, aryl, or heterocyclyl), —NR′C(O)R″ (where R′ is hydrogen or alkyl and R″ is alkyl, aryl, or heterocyclyl), and —NHS(O)2R′ (where R′ is alkyl, aryl, or heteroaryl).

“Arylalkyl” means a residue in which an aryl moiety is attached to a parent structure via one of an alkylene, alkylidene, or alkylidyne group. Examples include benzyl, phenethyl, phenylvinyl, phenylallyl and the like. “Lower arylalkyl” refers to an arylalkyl where the “alkyl” portion of the group has one to six carbons; this can also be referred to as C1-6 arylalkyl. When a group is referred to as “C1-C6 alkyl-aryl” or “C0-C6 alkyl-aryl”, an aryl moiety is attached to a parent structure via an alkylene group. Examples include benzyl, phenethyl, and the like.

“Arylalkyloxy” means an —OR group where R is arylalkyl, as defined herein.

“Carboxy ester” means a —C(O)OR group where R is lower alkanyl, lower alkenyl, lower alkynyl, cycloalkyl, aryl or arylalkyl, each of which is defined herein. Representative examples include methoxycarbonyl, ethoxycarbonyl, and benzyloxycarbonyl, and the like.

“Dialkylamino” means a —NRR′ radical where R and R′ are independently alkyl as defined herein, or an N-oxide derivative, or a protected derivative thereof, e.g., dimethylami no, diethylamino, N,N-methylpropylamino or N,N-methylethylamino, and the like.

“Fused-polycyclic” or “fused ring system” refers to a polycyclic ring system that contains bridged or fused rings; that is, where two rings have more than one shared atom in their ring structures. In this application, fused-polycyclics and fused ring systems are not necessarily all aromatic ring systems. Typically, but not necessarily, fused-polycyclics share a vicinal set of atoms, for example naphthalene or 1,2,3,4-tetrahydro-naphthalene. A spiro ring system is not a fused-polycyclic by this definition, but fused polycyclic ring systems of the invention may themselves have spiro rings attached thereto via a single ring atom of the fused-polycyclic. In some examples, as appreciated by one of ordinary skill in the art, two adjacent groups on an aromatic system may be fused together to form a ring structure. The fused ring structure may contain heteroatoms and may be optionally substituted with one or more groups. It should additionally be noted that saturated carbons of such fused groups (i.e. saturated ring structures) can contain two substitution groups.

“Haloaloxy” means an —OR′ group where R′ is haloalkyl as defined herein, e.g., trifluoromethoxy or 2,2,2-trifluoroethoxy, and the like.

“Halogen” or “halo” means fluoro, chloro, bromo or iodo.

“Haloalkyl” and “haloaryl” mean an alkyl and an aryl group, respectively, that are substituted with one or more halogens, preferably one to five halo atoms. Thus, “dihaloaryl,” “dihaloalkyl,” and “trihaloaryl” etc. refer to aryl and alkyl substituted with a plurality of halogens, but not necessarily a plurality of the same halogen; thus 4-chloro-3-fluorophenyl is within the scope of dihaloaryl.

“Heteroatom” refers to O, S, N, or P.

“Heterocyclyl” refers to a stable three- to fifteen-membered ring substituent that consists of carbon atoms and from one to five beteroatoms selected from the group consisting of nitrogen, phosphorus, oxygen and sulfur. For purposes of this invention, the heterocyclyl substituent may be a monocyclic, bicyclic or tricyclic ring system, which may include fused or bridged ring systems as well as spirocyclic systems. The terms “heterocycloalkyl” and “heteroaryl” are groups that are encompassed by the broader term “heterocyclyl.” The nitrogen, phosphorus, carbon or sulfur atoms in the heterocyclyl group may be optionally oxidized to various oxidation states. In a specific example, the group —S(O)0-2—, refers to —S— (sulfide), —S(O)— (sulfoxide), and —SO2— (sulfone). For convenience, nitrogens, particularly but not exclusively, those defined as annular aromatic nitrogens, are meant to include their corresponding N-oxide form, although not explicitly defined as such in a particular example. Thus, for a compound of the invention having, for example, a pyridyl ring; the corresponding pyridyl-N-oxide is meant to be included as another compound of the invention. In addition, annular nitrogen atoms may be optionally quatemized; and the ring substituent may be partially or fully saturated or aromatic. Examples of heterocyclyl groups include, but are not limited to, azetidinyl, acridinyl, benzodioxolyl, benzodioxanyl, benzofuranyl, carbazoyl, cinnolinyl, dioxolanyl, indolizinyl, naphthyridinyl, perhydroazepinyl, phenazinyl, phenothiazinyl, phenoxazinyl, phthalazinyl, pteridinyl, purinyl, quinazolinyl, quinoxalinyl, quinolinyl, isoquinolinyl, tetrazoyl, tetrahydroisoquinolyl, piperidinyl, piperazinyl, 2-oxopiperazinyl, 2-oxopiperidinyl, 2-oxopyrrolidinyl, 2-oxoazepinyl, azepinyl, pyrrolyl, 4-piperidonyl, pyrrolidinyl, pyrazolyl, pyrazolidinyl, imidazolyl, imidazolinyl, imidazolidinyl, dihydropyridinyl, tetrahydropyridinyl, pyridinyl, pyrazinyl, pyrimidinyl, pyridazinyl, oxazolyl, oxazolinyl, oxazolidinyl, triazolyl, isoxazolyl, isoxazolidinyl, morpholinyl, thiazolyl, thiazolinyl, thiazolidinyl, isothiazolyl, quinuclidinyl, isothiazolidinyl, indolyl, isoindolyl, indolinyl, isoindolinyl, octahydroindolyl, octahydroisoindolyl, quinolyl, isoquinolyl, decahydroisoquinolyl, benzimidazolyl, thiadiazolyl, benzopyranyl, benzothiazolyl, benzoxazolyl, firyl, tetrahydrofuryl, tetrahydropyranyl, thienyl, benzothienyl, thiamorpholinyl, thiamorpholinyl sulfoxide, thiamorpholinyl sulfone, dioxaphospholanyl, oxadiazolyl, tetrahydrofuranyl, tetrahydroisoquinolinyl, and tetrahydroquinolinyl.

“Heteroalicyclic” and “heterocycloalkyl” mean a non-aromatic heterocyclyl group, as defined herein. A “heteroalicyclic” or “heterocycloalkyl” may be fully saturated or may contain unsaturation, but is not aromatic. “Heteroalicyclic” or “heterocycloalkyl” may be monocyclic or bicyclic (including fused, bridged, and spiro ring systems).

“Optionally substituted heteroalicyclic” and “optionally substituted heterocycloalkyl” mean, respectively, a heteroalicyclic and heterocycloalkyl ring, each as defined herein, optionally substituted with one, two, three, four, or five groups selected from halo, haloalkyl, haloalkoxy, hydroxy, oxo, lower alkanyl, lower alkenyl, lower alkynyl, alkoxy, optionally substituted cycloalkyl, heterocycloalkyl, optionally substituted aryl, optionally substituted heteroaryl, alkylaminoalkyl, dialkylaminoalkyl, carboxy, carboxy ester, —C(O)NR′R″ (where R′ is hydrogen or alkyl and R″ is hydrogen, alkyl, aryl, or beterocyclyl), —NR′C(O)R″ (where R′ is hydrogen or alkyl and R″ is alkyl, aryl, or beterocyclyl), amino, alkylamino, dialkylamino, and —NHS(O)2R′ (where R′ is alkyl, aryl, or heteroaryl).

“Heteroaryl” means a 5- to 12-membered, monocyclic aromatic heterocyclyl (where heterocyclyl is defined herein) or bicyclic heterocyclyl ring system (where at least one of the rings in the bicyclic system is aromatic) where the monocyclic ring and at least one of the rings in the bicyclic ring system contains one, two, three, four, or five heteroatom(s) selected from nitrogen, oxygen, phosphorous, and sulfur.

Fused, bridged, and spiro moieties are also included within the scope of this definition.

“Optionally substituted heteroaryl” means a heteroaryl group, as defined herein, optionally substituted with one, two, three, four, or five groups selected from halo, haloalkyl, haloalkoxy, lower alkanyl, lower alkenyl, lower alkynyl, alkoxy, hydroxy, oxo (valency rules permitting), carboxy, carboxy ester, amino, alkylamino, dialkylamino, optionally substituted cycloalkyl, optionally substituted heterocycloalkyl, heteroaryl, optionally substituted aryl, —C(O)NR′R″ (where R′ is hydrogen or alkyl and R″ is hydrogen, alkyl, aryl, or heterocyclyl), —NR′C(O)R″ (where R′ is hydrogen or alkyl and R″ is alkyl, aryl, or heterocyclyl), and —NHS(O)2R′ (where R′ is alkyl, aryl, or heteroaryl).

“Optionally substituted heterocyclylalkyl” means an alkyl group substituted with an optionally substituted heterocyclyl group, as defined herein. Examples include (4-methylpiperazin-1-yl)methyl, (morpholin-4-yl)methyl, (pyridin-4-yl)methyl, 2-(oxazolin-2-yl)ethyl, 4-(4-methylpiperazin-1-yl)-2-butenyl, and the like. In addition, the alkyl portion of a heterocyclylalkyl group may be substituted as described in the definition for “substituted”. “Lower heterocyclylalkyl” means a heterocyclylalkyl where the “alkyl” portion of the group has one to six carbons. “Heteroalicyclylalkyl” or “lower heterocycloalkylalkyl” means a heterocyclylalkyl where the heterocyclyl portion of the group is non-aromatic; and “heteroarylalkyl” means a heterocyclylalkyl where the heterocyclyl portion of the group contains an aromatic ring. Such terms may be described in more than one way, for example, “lower heterocyclylalkyl” and “heterocyclyl C1-6alkyl” are equivalent terms. Additionally, for simplicity, the number of annular atoms (including heteroatoms) in a heterocycle may be denoted as “Cx-Cy” (as in “Cx-Cy-heterocyclyl” and “Cx-Cy-heteroaryl” (and the like)), where x and y are integers. So, for example, C5-C14-heterocyclyl refers to a 5 to 14 membered ring system having at least one heteroatom and not a ring system containing 5 to 14 annular carbon atoms.

“Hydroxyalkyl” means an alkanyl, alkenyl, or alkynyl radical, as defined herein, substituted with at least one, preferably one, two, or three, hydroxy group(s), provided that if two hydroxy groups are present they are not both on the same carbon atom. Representative examples include, but are not limited to, hydroxymethyl, 2-hydroxyethyl, 2-hydroxypropyl, 3-hydroxypropyl, 1-(hydroxymethyl)-2-methylpropyl, 2-hydroxybutyl, 3-hydroxybutyl, 4-hydroxybutyl, 2,3-dihydroxypropyl, 1-(hydroxymethyl)-2-bydroxyethyl, 2,3-dihydroxybutyl, 3,4-dihydroxybutyl and 2-(hydroxymethyl)-3-hydroxypropyl, preferably 2-hydroxyethyl, 2,3-dihydroxypropyl, or 1-(hydroxymethyl)-2-hydroxyethyl, and the like.

“Optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. One of ordinary skill in the art would understand that with respect to any molecule described as containing one or more optional substituents, only sterically practical and/or synthetically feasible compounds are meant to be included. “Optionally substituted” refers to all subsequent modifiers in a term. So, for example, in the term “optionally substituted arylC1-8 alkyl,” both the “C1-8 alkyl” portion and the “aryl” portion of the molecule may or may not be substituted. A list of exemplary optional substitutions is presented below in the definition of “substituted.”

“Saturated bridged ring system” refers to a bicyclic or polycyclic ring system that is not aromatic. Such a system may contain isolated or conjugated unsaturation, but not aromatic or heteroaromatic rings in its core structure (but may have aromatic substitution thereon). For example, hexahydro-furo[3,2-b]furan, 2,3,3a,4,7,7a-hexahydro-1H-indene, 7-aza-bicyclo[2.2.1]heptane, and 1,2,3,4,4a,5,8,8a-octahydro-naphthalene are all included in the class “saturated bridged ring system.”

“Spirocyclyl” or “spirocyclic ring” refers to a ring originating from a particular annular carbon of another ring. For example, as depicted below, a ring atom of a saturated bridged ring system (rings B and B′), but not a bridgehead atom, can be a shared atom between the saturated bridged ring system and a spirocyclyl (ring A) attached thereto. A spirocyclyl can be carbocyclic or heteroalicyclic.

“Substituted” alkyl, alkylene, alkylidene, and alkylidyne refer respectively to alkyl, alkylene, alkylidene, and alkylidyne where one or more (for example up to about five, in another example, up to about three) hydrogen atoms are replaced by a substituent independently selected from halo, optionally substituted aryl, hydroxy, alkoxy, optionally substituted heterocyclyl, alkylenedioxy, amino, alkylamino, dialkylamino), amidino, aryloxy, arylalkyloxy, carboxy, carboxy ester, alkylcarbonyloxy, carbamyl, alkylaminocarbonyl, dialkylaminocarbonyl, benzyloxycarbonylamino (CBZ-amino), cyano, acyl, nitro, S(O)n1R′ (where n1 is 0, 1, or 2 and R′ is alkyl, substituted alkyl, optionally substituted aryl, optionally substituted heterocycloalkyl, or optionally substituted heteroaryl), oxo, acylamino, and sulfonamido.

“Sulfonamido” means a —NRSO2R′ or —SO2NRR″ group where R is hydrogen or lower alkyl, R′ is lower alkanyl, lower alkenyl, optionally substituted aryl, optionally substituted heterocycloalkyl, optionally substituted cycloalkyl, or optionally substituted heteroaryl, and R″ is hydrogen or R′.

Representative compounds from Section III are depicted below. The examples are merely illustrative and do not limit the scope of the invention in any way. Compounds of the invention are named according to systematic application of the nomenclature rules agreed upon by the International Union of Pure and Applied Chemistry (IUPAC), International Union of Biochemistry and Molecular Biology (IUBMB), and the Chemical Abstracts Service (CAS).

Synthetic Procedures

Fusion of the reagents at 180° C. in the presence of K2CO3 and metallic copper was known to provide these compounds in low yield (S. H. Dandegaonker and C. K. Mesta, J. Med. Chem. 1965, 8, 884). New method was utilized that brief heating of the reagents in DMF in the presence of K2CO3, commercially available 2,3-dichloroquinoxaline and substituted arysulfonamides were formed in quantitative yields (S. V. Litvinenko, V. I. Savich, D. D. Bobrovnik, Chem. Heterocycl. Compd. (Engl. Transl), 1994, 30, 340).

The displacement of the active chlorine atom in above compounds was treated with 2,5-dimethoxy-phenylamine (nucleophile) in refluxing DMF to give the desired compounds in quantitative yields (S. V. Litvinenko, V. I. Savich, D. D. Bobrovnik, Chem. Heterocycl. Compd. (Engl. Transl), 1994, 30, 340).

On the other hand, the syntheses of other quinoxaline derivatives were well documented (W. C. Lumma, R. D. Hartman, J. Med. Chem. 1981, 24, 93).

The following compounds were prepared in a manner similar to that described above: N-(3-{[2,5-bis(methyloxy)phenyl]amino}quinoxalin-2-yl)-3-nitrobenzenesulfonamide; N-(3-{[2,5-bis(methyloxy)phenyl]amino}quinoxalin-2-yl)-4-chlorobenzenesulfonamide; N-(3-chloroquinoxalin-2-yl)-3-nitrobenzenesulfonamide; and 4-chloro-N-(3-chloroquinoxalin-2-yl)benzenesulfonamide.

General Library Procedure 8

Into a small 1 dram vial was added 3-(N-(3-(2-chloro-5-methoxyphenylamino)quinoxalin-2-yl)sulfamoyl)benzoic acid (61 mg, 0.13 mmol, 1.1 equiv). The acid was dissolved in 1 mL of DMA and DIPEA (42 uL, 0.24 mMol, 2 equiv) was added then added to the solution. The amine reagent (1 mL of 0.12 M solution in DMA) was added to solution with stirring followed by HATU (64 mg, 0.17 mMol, 1.4 equiv). Reaction was stirred overnight at room temperature. Upon completion as indicated by LCMS analysis, 2 mL of methanol was added to the solution. Preparative reverse-phase HPLC was used to isolate the desired product directly from this crude reaction solution. A Waters Fractionlynx preparative reverse-phase HPLC; equipped with a Waters SunFire Prep C18, OCD 5 μM, 30×70 mm column and running a 5-100% gradient with a binary solvent system of 25 mM ammonium acetate in water/acetonitrile; was used to carry out the purification.

General Procedure 8A

The General Library Procedure outlined in Procedure 8 was used to incorporate a number of amines that contained a second amine group protected as the tert-butylcarbamate. A subsequent deprotection after HPLC purification was performed to unmask this second amine group. Into a small 1 dram vial was added 3-(N-(3-(2-chloro-5-methoxyphenylamino)quinoxalin-2-yl)sulfamoyl)benzoic acid (61 mg, 0.13 mmol, 1.1 equiv). The acid was dissolved in 1 mL of DMA and DIPEA (42 uL, 0.24 mmol, 2 equiv) was added then added to the solution. The mono-Boc-protected diamine reagent (1 mL of 0.12 M solution in DMA, 1 equiv) was added to solution with stirring followed by HATU (64 mg, 0.17 mmol, 1.4 equiv). Reaction was stirred overnight at room temperature. Upon completion as indicated by LCMS analysis, 2 mL of methanol was added to the solution. Preparative reverse-phase HPLC was used to isolate the desired product directly from this crude reaction solution. A Waters Fractionlynx preparative reverse-phase HPLC; equipped with a Waters SunFire Prep C18, OCD 5 μM, 30×70 mm column and running a 5-100% gradient with a binary solvent system of 25 mM ammonium acetate in water/acetonitrile; was used to carry out the purification. The product fractions were combined and concentrated to dryness under reduced pressure by rotary evaporation. A solution of 4 N HCl in dioxane (2 mL) was added. The solution was then stirred at room temperature until no starting material was detected. The deprotected product precipitated out of solution as an HCL salt and was collected by filtration, washed with ether and dried under vacuum.

The following compounds were prepared according to General Procedure 8A

Biological Assays

The compounds of the invention demonstrated the ability to bind to PI3K when tested in the assays described in Section II above. In another embodiment, the compounds in Section II and Section III bind to the PI3K with a binding affinity, for example, of about 50 μM or less, 20 μM or less, 10 μM or less, 5 μM or less, 2.5 μM or less or 1 μM or less. In an advantageous embodiment, the IC50 of the binding compounds is about 0.5 μM or less, about 0.3 μM or less, about 0.1 μM or less, about 0.08 μM or less, about 0.06 μM or less, about 0.05 μM or less, about 0.04 μM or less, 0.03 μM or less, in another embodiment, about 0.03 μM or less.

Biological Models

Several biological models were used to test the efficacy of a MEK compound of Formula I, Ia, Ic, Id, II, III, IV, or V in combination with a PI3K compound of Formula VI, VIa, VIb or VII or a PI3K compound of Formula VIII, VIIIa, VIIIb, or IX in inhibiting tumor cell proliferation. In brief, either A2058 or WM-266 melanoma cell lines (ATCC) were transplanted intradermally in the hindflank of athymic nude mice (Jackson Laboratories). Both cell lines contain the B-RAF V600E mutation (Solit et al., Nature 439: pages 358-362, February 2006) and the PTEN gene is deleted. The xenograft was allowed to grow and divide for 10 days. Starting on day 10, mice were treated daily with a vehicle control or with a selected compound from section I (MEK inhibitor of Formula I, Ia, Ic, Id, II, III, IV, or V) either alone or in combination with a compound from section II (PI3K inhibitor of Formulae Formula VI, VIa, VIb or VII) or a compound from section III (PI3K inhibitor of Formulae Formula VIII, VIIIa, VIIIb, or IX). The xenografts were allowed to grow for another 15 days and then the tumors were weighed.

Mice treated with the MEK inhibitor alone exhibited a 50-75% reduction in tumor growth over the 15 day treatment period. Mice carrying the A2058 xenograft and treated with a select MEK inhibitor at 10 mgs/kg showed a 60% reduction in tumor growth relative to mice treated with vehicle alone. Mice carrying the A2058 xenograft and treated with vehicle had a mean tumor weight of approximately 1100 mgs versus mice who were treated with the select MEK inhibitor who had a mean tumor weight of 450 mgs. Mice carrying the WM-266 xenograft and treated with vehicle had a mean tumor weight of 700 mgs while mice carrying the same xenograft and treated with the select MEK inhibitor had a mean tumor weight of 200 mgs. The MEK inhibitor inhibited the tumor growth of both tumors by 60-75% over the 15 day period of treatment.

Mice treated with a combination of MEK inhibitor and a selected Section II or Section III PI3K inhibitor also exhibited a reduction in tumor growth over the 15 day treatment period. Mice carrying the A2058 xenograft and treated with a select Section III PI3K inhibitor at 100 mgs/kg exhibited a 65% reduction in growth relative to animals treated with the vehicle alone (mean tumor size of 375 mgs for Section III PI3K inhibitor treated animals vs 1100 mgs for vehicle treated animals). Animals treated with a combination of a select MEK inhibitor (10 mgs/kg) and a selected Section III PI3K inhibitor (100 mgs/kg) exhibited an 80% reduction in tumor growth over the 15 day treatment period (mean tumor size of 200 mgs for the tumors treated with the combination of compounds vs 1100 mgs for the vehicle treated tumors).

Mice carrying the A2058 xenograft and treated with a select Section II PI3K inhibitor at 100 mgs/kg exhibited a 65% reduction in growth relative to animals treated with the vehicle alone (mean tumor size of 350 mgs for PI3K inhibitor treated animals vs 1100 mgs for vehicle treated animals). Animals treated with a combination of a select MEK inhibitor (10 mgs/kg) and a selected Section II PI3K inhibitor (100 mgs/kg) exhibited an 75% reduction in tumor growth over the 15 day treatment period (mean tumor size of 250 mgs for the tumors treated with the combination of compounds vs 1100 mgs for the vehicle treated tumors).

Similar results were observed in animals carrying the WM-266 xenograft and treated with the same combination of drugs. Mean tumor weights for the animals treated with the vehicle alone were 700 mgs after 15 days of treatment. Animals that had received the Section III PI3K or Section II PI3K inhibitors exhibited a 50% reduction in tumor growth (mean tumor size of 500 mgs for the tumors treated with each compound) and an 85% reduction in tumor growth for tumors treated with the combination of a select MEK and either the Section II PI3K or Section III PI3K inhibitors (mean tumor size of 100 mgs after 15 days of combination treatment).

Xenographs treated with the combination of a select MEK inhibitor and either a select Section III PI3K inhibitor or a select Section II PI3K inhibitor exhibited a greater reduction in tumor growth than tumors treated with either compound alone.

The foregoing invention has been described in some detail by way of illustration and example, for purposes of clarity and understanding. The invention has been described with reference to various specific and preferred embodiments and techniques. However, it should be understood that many variations and modifications may be made while remaining within the spirit and scope of the invention.
