Tripeptides having hypotensive activity, to be defined by the following general formula:
wherein:
A represents a residue of L-pyroglutamic acid, L-proline or L-proline bearing a substituent on its amino group
wherein R, is an acyl with a number of carbon atoms in straight chain not higher than 9, a benzyloxycarbonyl group or an alkyloxycarbonyl group;
B is an a-aminoacidic residue deriving from one of the natural aminoacids;
C is a residue of L-tryptophan (Trp), of L-phenylalanine (Phe) or of L-tyrosine (Tyr);
Z is a hydrogen atom or an alkyl group with a number of carbon atoms in straight chain not higher than 9.
