摘要： A novel peptide possessing excellent antihypertensive activity is disclosed. The peptide has the formula:Pro-Thr-His-Ile-Lys-Trp-Gly-Asp (I)and can be prepared by purifying a fluid extracted from fish tissues or by combining constituting amino acids by a peptide synthesis method. It exhibits excellent ACE inhibitory activity, low toxicity, and good stability, and is thus an extremely useful and effective antihypertensive substance.

摘要： New peptide derivatives represented by the following general formulaR.sub.1 -Pro-Hyp-R.sub.2wherein R.sub.1 is a hydrophobic radical, R.sub.2 is a hydrophilic radical, 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 peptide derivative can be used in the form of parenteral injections, tablets, capsules or powder, the typical daily dose being in the range from 1 mg to 500 mg for adults.
