Compounds which modify serotoninergic transmission, diagnostic and therapeutic applications

Abstract

Compounds having the following peptide sequence: X Leu Y, wherein X is H or Ala or Leu-Ser-Ala, Y is OH or peptide sequence having from 1 to 10 amino acids, with the terminal carboxy end being amidified by a NH2 group, or esterified by a substituted or non-substituted hydrocarbyloxy, with the proviso that X and Y are not simultaneously H and OH, respectively, The invention also concerns the corresponding compounds wherein the peptide binding group —CO—NH— is replaced by a binding group resisting protease enzymatic degradation, or wherein the peptide backbone comprises one or more intercalated groups making the peptide binding resistant to enzymatic degradation. Also described are compounds comprising a grouping whose spatial structure is substantially identical to that of a peptide of the sequence X-Leu-Y wherein X and Y have the above-mentioned definition.
