title: Beta-homo-amino acid scan of angiotensin IV.
abstract: Angiotensin IV, a metabolite of angiotensin II, inhibits the enzyme insulin regulated aminopeptidase or IRAP and also, although with lower potency, aminopeptidase-N (AP-N). When both beta (2)-homo amino acid- and beta (3)-homo amino acid substitutions were used, allowed the identification of H-( R)beta (2)hVal-Tyr-Ile-His-Pro-beta (3)hPhe-OH as a potent and stable Ang IV analog with high selectivity for IRAP versus AP-N and the AT1 receptor.
