TRIPEPTIDE DERIVATIVES FOR THE TREATMENT OF NEURODEGENERATIVE DISEASES

摘要

The invention relates to the use of specific tripeptides for the treatment of neurodegenerative diseases. The tripeptide derivatives satisfy the following formula (I): wherein X represents OH, (C1-5)alkoxy, NH2, NH-C1-5-alkyl, N(C1-5 alkyl)2; R1 is a residue derived from any of the amino acids Phe, Tyr, Trp, Pro, each of which may optionally be substituted by a (C1-5) alkoxy group, a (C1-5) alkyl group or a halogen atom, and Ala, Val, Leu, or Ile; R2 is a residue which is derived from any of the amino acids Gly, Ala, Ile, Val, Ser, Thr, His, Arg, Lys, Pro, Glu, Gln, pGlu, Asp, Leu and Asn; R3 and R4 independently represent H, OH, (C1-5)alkyl, or (C1-5)alkoxy, provided that R3 and R4 are not both OH or (C1-5)alkoxy; R5 represents H, OH, (C1-5) alkyl or (C1-5)alkoxy; and wherein R0 preferably represents a cinnamoyl residue; or pharmaceutically acceptable salts thereof.
