NEW POLYTERPENE TYPE COMPOUNDS, COMPOSITIONS CONTAINING

THEM AND TOPICAL USES THEREOF

TECHNICAL FIELD

The present invention relates to novel compounds of terpenic type, in particular of geranylgeranyl type (including four terpene patterns, also known as isoprene), compositions comprising them and topical uses thereof.

The present invention concerns the chemical, dermo-medical or cosmetical industries for the hygiene and personal care of the skin and apendages (such as hair, eyelashes, eyebrows, nails, hairs) of mammals, animals or humans.

BACKGROUND ART

Geranylgeranyl pattern is coupled to many cellular proteins, regulating their activity as well as addressing them in different cellular compartments. The transfer on the proteins is performed by a geranylgeranyltransferase which ensures the coupling with the energy released during the rupture of the phosphate bond of isoprene skeleton-P04:

Generally, isoprenes have affinities with the protein helical transmembrane parts and promote by their presence the protein-protein interactions by improving their mobility within the membranes. These protein accompanying properties make the geranylgeranyl isoprene in particular a pivot molecule of the cellular function both at the level of the membrane receptors and the level of the functionality of intracellular proteins and of their addressing. It is a sort of physiological facilitator.

Compounds comprising a pattern of geranylgeranyl type have already been proposed and in cosmetics such as:

- Geranylgeraniol in anti-aging, active promoter of collagen synthesis (JP2008189607) and having the following formula:

This compound is also described in combination with retinol also for anti-aging properties (US5756109).

- Geranyl geranyl acetone called teprenone known for its whitening (EP0561305), anti-aging (EP1879538) and humectant (JP7309710) properties and having the following formula: The article "Cyclisation of high terpenoids acids and their esters in superacid" in the Journal "Izvestiya Zkademii Nauk, Seriya Khimicheskaya", (1995), (12), 2507-13, discloses the terpenoid compound:

Thereafter in the description called the GGPM (formula V).

The article "Effect of synthetic acyclic polyisoprenoids on the cold-restraint stress induced gastric ulcer in rats" in the Japanese Journal of Pharmacology (1983), 33(3), 549-56, discloses the terpenoid compound

Thereafter in the description called the GGPE (formula IV).

The present invention aims to propose alternative compounds for cosmetic and pharmacy industries still in demand for new ingredients, including ingredients that may be active on several targets in order to offer a range of complementary activities.

SUMMARY OF THE INVENTION

To this end, the present invention proposes polyterpenic compounds corresponding to formula I below:

with n = 0 to 5, m = 0 to 5, Ri, R2 and R3, independently of each other, selected from H, an alkyl chain of 1 to 6 carbon atoms, an alcohol, alkoxy, amine and substituted amine group, and R4 selected from an alkyl, aryl, aralkyl, acyl, sugar or alkoxy chain of 1 to 6 carbon atoms,

and corresponding ami -acid or peptides derivatives corresponding to the following formula VI

(Xaa)p entity being either an amino-acid (with p=l), or any peptide having p amino-acids with p between 1 and 10.

More particularly, the subject matter of the present invention is directed to compounds of formula I and to compounds of formula VI,

with the exclusion in formula I of the compounds corresponding to n=3, m=0, Ri=H and R4=methyl or ethyl (corresponding to the GGPM and the GGPE). Preferably n=3 in formulas I and VI so as to form a geranyl geranyl group.

The present invention also encompasses the chemical analogues of these compounds.

As further detailed in the description, results of in vitro tests have been obtained with the compounds of the invention that open a strong potential for applications in cosmetics, nutraceutics or pharmaceutics in particular dermatology. "Oleodensifying" properties, an alternative to the

"lipofilling", giving volume through the stimulation of adipogenesis and thus allowing compensating subcutaneous volume deficits, depigmenting, anti-oxidant and firming properties were in particular highlighted.

According to other preferred particular features:

m = 0 or 1 ; and/or

R4 is an alkyl group of 1 to 6 carbon atoms, in particular preferably ethyl or methyl group; and/or

Ri, R2 and R3 are, independently from each others, either a methyl or a hydrogen atom, R2 being preferably a methyl.

The invention encompasses in particular the following compounds:

- The Geranyl Geranyl Ethyl Hexanoate having the following developed formula II and called thereafter in

With n = 3, m = 0, Ri = methyl and R4 = ethyl.

The Geranyl Geranyl Ethyl Octadienoate of the following developed formula III and called

With n = 3, m = 1, Ri = H, R2 = methyl, R3 = H and R4 = ethyl.

Farnesyl type compounds (n=2) are also examples within the scope of the present invention.

The manufacturing process can advantageously be based on a Wittig reaction with teprenone and the adequate triphenylphosphine Wittig reagent as starting reagents, as can be seen in the reaction scheme given below, illustrate the GGOE:

Formula III - GGOE Other manufacture processes are of course possible.

Advantageously, as mentioned above, the invention compounds can be coupled to a (Xaa)p entity which is either an amino-acid (with p=l), or any peptide having p amino-acids with p between 2 and 10 in order to obtain compounds of the following developed formula, according to the following reaction scheme:

with p comprised between 1 and 10.

The compounds of the invention thus constitute an alternative to conventional lipid chains linked to peptides, as a palmitoyl or elaidoyl chain, whose function is to improve the bioavailability of peptide and its ability to penetrate the skin, and to form a synergy with the coupled peptide activity.

The invention covers peptides consisting of encoded amino acids, natural or unnatural, derivatives and analogs, pure or in mixtures (encoded amino acids: Alanine A Ala, Arginine R Arg, Asparagine N Asn, Aspartate or aspartic acid D Asp, Cysteine C Cys, Glutamate or glutamic acid E Glu, Glutamine Q Gin, Glycine G Gly, Histidine H His, I He Isoleucine, Leucine L Leu, Lysine K Lys, Methionine M Met, Phenylalanine F Phe, Proline P Pro, Serine S Ser, Threonine T Thr, Tryptophan W Trp, Tyrosine Y Tyr, Valine V Val). Are cited for example, without limitation, the amino acids K, T, C, M, MO (methionine whose sulfur is oxidized), M02 (methionine whose sulfur is dioxidized), the dipeptides KT, KC, KP, VW, KK or TT, the tripeptides GHK, GKH, KPK, KMOK, KM02K or KAvaK, the tetrapeptides GQPR, the pentapeptides KTTKS, the hexapeptides GKTTKS, etc.

n = 3, Ri = H, m = 0 and R4 = ethyl, corresponding to the coupling of the GGPE with an amino-acid or a peptide.

n = 3, Ri = H, m = 0 and R4 = methyl, corresponding to the coupling of the GGPM with an amino-acid or a peptide.

ln-vitro test results given in the following detailed description show that the compounds of the invention are more particularly useful for preventing or treating the cutaneous signs of aging, in particular through anti-radical and anti-oxydant actions, protection against UV radiations, improvement of the mechanical properties of skin (elasticity, firmness, compressibility), lightening of the skin and treatment of melanin spots (all indication in relation with the decrease of melanogenesis), and for gaining a "lipofilling" effect (restoring/giving volume by stimulating the expansion of adipose tissue). The present invention also proposes a topical composition, characterized in that it comprises, in a physiologically acceptable medium, as active ingredient, an effective amount of one or more compounds to formula I:

with n = 0 to 5, m = 0 to 5, Ri, R2 and R3, independently of each other, selected from H, an alkyl chain of 1 to 6 carbon atoms, an alcohol, alkoxy, amine and substituted amine group, and R4 selected from an alkyl, aryl, aralkyl, acyl, sugar or alkoxy chain of 1 to 6 carbon atoms,

and corresponding ami -acid or peptides derivatives corresponding to the following formula VI:

(Xaa)p entity being either an amino-acid (with p=l) or any peptide having p amino-acids with p between 1 and 10.

Preferably n=3 in formulas I and VI so as to form a geranyl geranyl group.

Such composition can be used in the cosmetical field to improve the overall appearance/condition of the skin and in dermo-pharmaceutical field to for preventing or treating disorders and diseases of the skin and appendages.

According to other preferred particular features:

m = 0 or 1; and/or

R4 is an alkyl group of 1 to 6 carbon atoms, in particular preferably ethyl or methyl group; and/or

Ri, R2 and R3 are, independently from each others, either a methyl or a hydrogen atom, R2 being preferably a methyl.

Examples

1/ Formulation of an active ingredient according to the invention

The compounds of the invention can be dissolved in a hydrophobic matrix (e.g. based on triglycerides) at a concentration typically of 2% w/w (=with regard to the total weight of the composition), corresponding to 20 000 ppm, in order to form an active ingredient that can be used in the manufacture of cosmetic products (as disclosed in below galenic examples of point 3 /).

21 In vitro TESTS

The compounds of the invention demonstrate various activity cosmetics, affecting several domains of the skin physiology.

2/1 Activity of the invention compound on adipocyte differentiation:

Some cosmetic compounds seek to encourage the installation of the subcutaneous fat for better aesthetics and greater volume. In this regard, in vitro tests were implemented in order to observe the increase of adipocyte differentiation on cultured pre-adipocytes (with glycero 1-3 -phosphate dehydrogenase (G3PDH) as the key enzyme of this differentiation).

Effect of the compounds according to the invention on the G3PDH activity

Principle: 3T3-L1 cells were grown to sub-confluence, then induced to differentiate with the appropriate cocktail in the presence or absence of geranyl geranyl hexenoate acetate (GGHE) or geranyl geranyl octadieneoate acetate (GGOE) at different concentrations. After three days of incubation, the cocktail of differentiation is replaced by a new culture medium in the presence or absence of GGHE or GGOE. After 3 days of incubation, the cell layers were recovered and G3PDH activity is assayed, and then divided by the number of cells.

Table 1: Effect of GGHE and GGOE on G3PDH activity by cell in the adipocyte culture

Thus, the compound of the invention, here the GGOE or GGHE at 5 and 1 ΟμΜ, significantly stimulates adipocyte differentiation. According to this result, the compounds can be recommended in any cosmetic composition for promoting expansion and/or formation of subcutaneous adipose tissue and/or stimulate lipogenesis and/or adipogenesis and/or adipocyte differentiation.

2/2 Activity of the compound according to the invention on melanogenesis of human melanocytes in monolayers:

The cosmetics industry is looking for compounds with depigmenting (whitening, skin depigmenting and lightening, elimination or mitigation of freckles, age spots etc.). In vitro, it is possible to demonstrate such an effect by measuring the melanin synthesized by melanocytes cultures that had or not been in contact with the compounds to be evaluated.

Effect of the compounds according to the invention on the quantity of synthetized melanin

Principle: Human melanocytes are cultured and contacted or not with the geranylgeranyl ethyl hexenoate (GGHE) or the geranylgeranyl methyl pentenoate (GGPM), at different concentrations, for 5 days. After incubation, the melanin content is measured in the cell homogenates, then divided by the cell number.

Table 2: Effect of GGHE and GGPM on melanin synthesis with regard to cell in a melanocyte cuture

Product Concentration Melanin (% Change/Control)

GGHE lppm -10% p < 0.01

3ppm -22% p < 0.01

5ppm -30% p < 0.01 7ppm -37% p < 0.01

lOppm -47% p < 0.01

GGPM lppm -6% p < 0.01

3ppm -24% p < 0.01

5ppm -36% p < 0.01

7ppm -44% p < 0.01

lOppm -48% p < 0.01

Arbutin (positive control) 0.06% = -57%; p<0.01

A significant and dose dependant decrease of the melanin synthesis by the human melanocyte is observed in the presence of the two GGHE and GGPM compounds of the invention.

2/3 Anti-radical and anti-oxydant effects of the compounds of the invention:

Oxygen free radicals are produced during normal physiological processes such as breathing or the inflammatory response, but may cause serious cell damage involved in skin aging if produced in excessive amounts (oxidative stress), then passing over the antioxidant defense mechanisms. Therefore, in particular according to this, anti-radical compounds, and thus the invention compounds, can present an interest in the anti-aging cosmetic compositions.

Principle: The ORAC test (Oxygen-Radical Absorbance Capacity) measures the oxidative degradation of a fluorescent molecule (fluorescein). Degradation of fluorescein by peroxyl radicals generated by AAPH (2,2 '-azobis (2-amidinopropane) dichloride) induces a decrease in fluorescence that can be measured by a spectrofluorometer, during a degradation kinetic.

An antioxidant protects fluorescein against this radical degradation. The fluorescence decrease will be smaller and slower in the presence of the antioxidant than in its absence. The comparison between the two kinetic parameters enables to calculate a protection percentage against free radical degradation.

Table 3: Effect of GGHE, GGOE and GGPM on fluorescein degradation by peroxyl radicals

Positive control = Trolox 2μΜ = 47% (p<0.01); nsd = non significative data

A significant protection against peroxyl radicals in the presence of GGPE, GGHE and GGOE, each at 1 Oppm, is observed. The compounds according to the invention have in this test an antiradical activity higher to geranylgeranylacetone (GGA), known anti-aging molecule (the subject matter of a patent of the Applicant).

2/4 Keratinocyte protection against UVB by the invention compounds:

Skin is very sensitive to UV radiations. Overexposure to the sun (which includes UV A and B in its spectrum) can lead to premature aging of the skin, and even to cancer process. Thus, it is important for the cosmetics industry to find compounds able to counteract the negative effects of UV radiations. Keratinocytes in monolayer after UVB irradiation (12 to 240mJ/cm 2) develop on their surface many buds, separate themselves from the culture support and are damaged that can go up to death. A cell count at various times after UVB irradiation can be used to evaluate the cell viability of the culture. This model is widely used in cosmetics to evaluate the protective effect of various compounds against the deleterious effects of UVB stress.

Principle: Keratinocytes are cultured in 35mm Petri dish. Just at confluence, the cells are contacted or not with the GGHE and GGOE invention compounds for 24 hours. UVB irradiation (50mJ/cm 2) is performed the next day, and then the cells are or not contacted with the invention compounds. 6 days later, the cells are counted to determine cell viability.

Table 4: Quantification of the number of cells post UVB stress

The GGHE and GGOE compounds according to the invention, at concentations of 1 and 2,5ppm have a significant protective effect against the UVB stress effects.

2/5 Action on decorin, molecule of the dermis:

Decorin is a leucine-rich proteoglycan involved in the assembly of the dermis, by binding to collagen fibers and tropoelastin. The quality of this assemblage reflects the skin mechanical properties: elasticity, compressibility and firmness.

Principle: Normal human fibroblasts were brought to confluence and then placed or not in contact with the GGPE, GGOE and GGHE invention compounds, at 5ppm, for 3 days. After this incubation, decorin content was assayed by ELISA in cell homogenates, and divided by the number of cells.

Table 5: Effect of GGHE, GGOE and GGPE on the biosynthesis of decorin with regard to cell in a fibroblast culture

Control GGPE 5ppm GGHE 5ppm GGOE 5ppm

Stimulation % +62% +56% +54%

REF

Student t test p<0.01 p<0.01 p<0.01 A significant increase in the decorin synthesis by human fibroblast is observed in the presence of 5ppm of the GGHE, GGPE and GGOE compounds of the invention.

2/6 Action on nidogen 1, molecule of the dermal-epidermal junction:

Nidogen 1 is a key component of the basal membrane. It stabilizes and strengthens the basal membrane by linking laminin to collagen 4.

Principle: Normal human fibroblasts were brought to confluence and then placed or not in contact with the GGPE, GGOE and GGHE compounds of the invention at 5ppm for 3 days. After this incubation, the content Nidogen 1 is determined by ELISA in cell homogenates, and divided by the number of cells.

Table 6: Effect of GGHE, GGOE and GGPE on nidogen 1 biosynthesis by cell in a fribroblast culture

A significant increase of the nidogen 1 synthesis by human fibroblast is observed in the presence of 5ppm of each of the four compounds according to the invention (GGPM, GGPE, GGHE and GGOE).

Other activities can of course be highlighted according to other appropriated tests, in particular using in vivo tests.

2/7 Influence of the GGOE on the syndecan 1 synthesis by human keratinocytes

Syndecan 1 is a small proteoglycan transmembran protein that is strongly implicated in keratinocyte activation and cohesion. The production of syndecan 1 diminishes with age resulting in a lack of cohesion at the level of epidermis (in the supra basal layers).

Principle: Human keratinocytes are cultivated in a growth medium. After 6 days of incubation, the cells are contacted or not with the tested products (GGOE and GGA) at 3, 5 or 7 ppm for 48h. After incubation, the supernatants are taken and the syndecan 1 content is assayed by ELISA in these supernatants. The cell layers are sonicated and the cell number is evaluated by Hoechst method.

Table 7: Influence of GGOE (and compared to GGA) on syndecan 1 synthesis in human keratinocytes supernatants (n=3)

Concentration Syndecan 1 (pg / 106 cell) Change (%)

Control - 136.0 + 10.0 Reference

3ppm 141.3 ± 12.9 +4%; nsd

GGA 5ppm 155.7 + 14.4 +14%; nsd

7ppm 183.4 +/- 21.9 +35%; p< 0.05

Control - 136.4 + 19.0 Reference

3ppm 353.4 + 57.2 +159%; p<0.01

GGOE 5ppm 424.3 + 69.1 +2\ \%; p<0.01

7ppm 435.9 +/- 18.3 +220%; p< 0.01 The results show that there is a significant and dose dependent stimulation of the synthesis of syndecan 1 in human keratinocyte in the presence of GGOE (stimulation > 200% in the presence of 7ppm of GGP).

Comparatively, the GGA presents a low stimulating activity of syndecan 1 syntesis (stimulation < 50% in the presence of 7 ppm of GGA).

Therefore, GGOE can boost the synthesis of syndecan 1 in keratinocytes to reinforce the skin cohesion.
