Description

This peptide is also known as bradykinin-potentiating peptide 9a; it exhibits vasodilatory and antihypertensive activity. This peptide inhibits angiotensin-converting enzyme (ACE) in vivo, decreasing blood pressure. This peptide also inhibits hydrolysis of bradykinin and inactivation of leutinizing hormone-releasing hormone (LHRH).
