摘要:
The invention relates to a peptide of formula W-DPhe-Arg- Z (I) and to a conjugate thereof of a formula A-W-DPhe-Arg-Z (II), wherein A is a radical corresponding to a monocarboxylic acid of general formula HOOC-R (III), wherein R is an linear or branched possibly substituted by a hydroxy group aliphatic C1-C24 radical which can comprise one or several unsaturations, preferably from 1 to 6 unsaturations, a lipoic acid or the reduced form thereof, a dihydrolipoic acid, N-lipoyl-lysine or a phenylbutyric acid, W is His, Ala-His, Ala-Ala-His, Nle-Ala-His, DTrp-Ala-His, Nle-Trp-His, Lys, Ala-Lys, Nle-Ala-Lys, Orn, Ala-Orn, Nle-Ala-Orn, Ala, Nle-Ala-Ala, Arg, Ala-Arg, Nle-Ala-Arg, Nle-Ala-DTrp or a bond in case of compounds of formula (II), Z is NH2, OH and OR, wherein R is a linear or branched aliphatic C1-C24 radical, TrpNH2, NapNH2, TpiNH2, TicNH2, AlaNH2i TrpOH, NapOH, TpiOH, TicOH, AlaOH, PheNH2, or PheOH, exempting a peptidic conjugate for which A is a radical corresponding to an acetic acid, W is Nle-Ala-His and Z is TrpNH2 in the form of enantiomers or diastereoisomer and the mixtures thereof including racemic mixtures. The use of the inventive compounds for cosmetically fighting against canities is also disclosed.
摘要:
The subject matter of the present invention concerns a novel family of peptide conjugates of formula (I): A-X1-X2-Pro-Ala-X-B in which: - A is a hydrogen atom, a C6 to C20 acyl group or a cholesterol residue; - X1 is a covalent bond, an alanine or a proline; - X2 is an arginine, a lysine or an alanine; - X is a lysine, an alanine or a phenylalanine; and - B is a hydroxyl or an amine; or one of the salts thereof, which are preferentially pharmaceutically, dermatologically or cosmetically acceptable, and also the processes for the synthesis thereof, and the uses thereof for reducing hair loss and stimulating hair growth.
