    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.

    摘要: The novel derivatives of pepstatin have the general formula (I) below in which X, Y and Z, are identical or different, and each represent an amino-acid selected from arginine, glutamic acid, aspartic acid, lysine, histidine and valine, the carboxyl function of the terminal amino-acid being esterifiable. The indices a, b and c are each equal to zero or 1, the sum a+b+c being equal to 1, 2 or 3. The invention also includes the water soluble salts and their preparation, and the compositions containing them. ##STR1## These novel products are particularly useful in the diagnosis and treatment of arterial hypertension due to the action of renine.
