Abstract: 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(C1-5alkyl)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.

Abstract: The invention relates to the use of specific tripeptides for the treatment of postlesional diseases of ischemic, traumatic or toxic origin. The tripeptide derivatives satisfy 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-C5) 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.

Abstract: 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 or more (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.
