New peptide derivatives represented by the following general formula
wherein R, is a hydrophobic radical, R2 is a hydrophilic rodical,
Pro is prolyl and Hyp is hydroxyprolyl show more powerful Inhibitory action against platelet agglutination than conventional drugs and have potential use as anti-agglutination agent. The peptide derivative can be prepared by condensing a peptide containing a hydrophobic radical with a carboxylic acid containing a hydrophilic radical.
The invention relates also to pharmaceutical compositions containing the new peptide derivatives as active ingredients.
