Abstract: The invention relates to a dipeptide conjugate having general formula I, AA2-AA1-NH2, wherein A represent the radical corresponding to a monocarboxylic acid with general formula II, HOOC—R, in which: R represents a linear or branched aliphatic radical at C1-C24, which is optionally substituted by a hydroxyl group and which can comprise one or more unsaturations, preferably between 1 and 6 unsaturations, and/or which can comprise a phenyl group or lipoic acid or the reduced form thereof, dihydrolipoic acid or N-lipoyllysine; and AA1 and AA2 represent identical or different amino acids which are selected from the group containing Ala, Asn, Cys, Gln, Gly, Ile, Leu, Met, Phe, Pro, Ser, Thr, Trp, Tyr, Val, Asp, Glu, Arg, His, Lys, Orn, Dap, Dab, the corresponding homo-amino acids and the corresponding beta-amino acids in the form of enantiomers or diastereoisomers and mixtures thereof, including racemic mixtures.

Abstract: The invention relates to a tripeptide conjugate having general formula I, A-AA1-AA2-AA3-NH2, wherein A represents the radical corresponding to a monocarboxylic acid with general formula II, HOOC—R, in which: R represents a linear or branched aliphatic radical at C1-C24, which is optionally substituted by a hydroxyl group and which can comprise one or more unsaturations, preferably between 1 and 6 unsaturations, lipoic acid or the reduced form thereof, dihydrolipoic acid, N-lipoyllysine, or phenylbutyric acid; and AA1, AA2 and AA3, which may be identical or different, represent independently of each other an amino acid selected from His, Phe, Ala, Arg, Lys, Orn, Trp, Nap, Tpi and Tic, on the condition that at least one of AA1, AA2 or AA3 represent Phe, preferably Dphe in the form of enantiomers or diastereoisomers and mixtures thereof, including racemic mixtures.
