New peptide derivatives and their application, especially in therapeutics

摘要

The invention relates to the peptide derivatives of formula X - Y - Gly - Asp - Z - W in which X represents hydrogen, an amino acid residue or a group of formula DE - where D represents a physiologically acceptable N-protective group or hydrogen, and where E represents a single bond or an amino acid residue; Y represents an L-arginyl or D-arginyl residue; Z represents an L-phenylalanyl or D-phenylalanyl residue; W represents an OH group, an NH2 group, a group O-R<1> with R<1> representing a C1 to C4 alkyl radical, a group NHR<2> with R<2> representing a C1 to C4 alkyl radical, or an amino acid residue. -
