摘要:
The present invention relates to peptide derivatives of the general formula:R--X--Y--Statyl.sub.1 --Ala--Statyl.sub.2 --R' (1),in which:Statyl.sub.1 and Statyl.sub.2 represent the radical derived from the aminoacid statine,R denotes a hydrogen atom or an acylating group attached to the terminal amino group of the aminoacid X--,X and Y, which are identical or different, denote aminoacids of the L or D configuration if a center of asymmetry exists in the molecule, and optionally protected in their side chain, with the proviso that X and Y cannot simultaneously denote valine, andR' denotes OH, O-lower alkyl, NH.sub.2 or a group NH-R.sub.1, in which R.sub.1 represents a lower alkyl or lower aralkyl group.It also relates to a process for the preparation of the products of the formula (1) and to the medicaments containing a product of the formula (1) as the active principle.
