<p>The invention relates to the use of specific tripeptides for the treatment of neurodegenerative diseases, and to pharmaceutical compositions comprising the tripeptides. 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 one of the amino acids Phe, Tyr, Trp, Pro, which each may be optionally substituted with one ormore (C1-5) alkoxy groups, (C1-5) alkyl groups or halogen atoms, as well as Ala, Val, Leu or Ile; R2 is a residue derived from one of the amino acids Gly, Ala, Ile, Val, Ser, Thr, Leu and Pro; Y1 and Y2 independently from each other represent H or (C1-5) alkyl; R3 and R4 independently from each other represent H, OH, (C1-5) alkyl or (C1-5) alkoxy, provided that R3 and R4 are not both OH or (C1-5) alkoxy; and R5 represents H, OH, (C1-5) alkyl or (C1-5) alkoxy; or a pharmaceutically acceptable salt thereof.</p> |
