Conjugates of alphamsh with a fatty acid, preparation method therefor, and use thereof as a drug

摘要

A peptide conjugate comprising a peptide sequence that includes at least one sequence of four alpha MSH-derived amino acids optionally in a natural form, said sequence being chemically or physically conjugated with acids selected from either dicarboxylic acids of general formula (I): HOOC-R1-COOH, wherein R1 is a straight or branched alkylene radical having at least 3 and preferably 3-10 carbon atoms, and being optionally substituted, in particular by one or more amino or hydroxy groups; or alpha -monounsaturated fatty acids with a cis or preferably trans configuration, of general formula (II): R2-CH=CH-COOH, wherein R2 is a straight or branched alkyl radical having at least 6 and preferably 6-10 carbon atoms, and being substituted by an amino, hydroxy or oxo group.
