NEW PEPTIDE AND ITS PRODUCTION

摘要

PURPOSE:To provide a new peptide having an arterial relaxation action and an angiotensin transferase-inhibiting action and useful as an antihypertensive agent, and to provide the method for producing the same. CONSTITUTION:The new peptide is represented by H-Try-Thr-Ser-Trp-Ala-OH, is produced by hydrolyzing dried bonito with thermolysin (an enzyme), and may be used as its composition as such or, if necessary, after purified on its practical use. The peptide can also be produced by a conventional peptide synthesis method.
