Permissive Role

1. The angiotensin analogues Sar1-Ala8-angiotensin II (AII), Sar1-Ile8-AII, Sar1-Leu8-AII, Sar1-Thr8-AII, [Des1-Asp]-Ile8-AII and [Des1-Asp]-Sar2-Ile8-AII and converting enzyme inhibitor (SQ 80221) infused by intra-adrenal arterial infusion had no effect on aldosterone secretion in sodium-deficient sheep at doses in excess of those shown to block exogenous angiotensin II or III infusion. 2. It is suggested that the intrinsic agonist activity of the analogues may fulfil the requirements for a permissive role for angiotensin in the aldosterone response to sodium deficiency.

Angiotensin Ii Analogues

Angiotensin II (ATII), angiotensin I (ATI), and Acpc analogues of ATII, 8-Achc-ATII, 8-D-Phe-ATII, and 8-Ala-ATII, were incubated in vitro with carboxypeptidase, chymotrypsin, and leucine-aminopeptidase in order to study the influence of unnatural amino acids (Acpc, Achc, and D-Phe) and of L-Ala on the activity of peptidases.Fragments occurring during the breakdown of peptides were demonstrated by paper chromatography in an ascending system.ATII and ATI are rapidly inactivated by carboxypeptidase and chymotrypsin, while the degradation by leucine-aminopeptidase is slower.Substitution of L-Phe with Acpc, Achc, D-Phe, or L-Ala in position 8 prevents the degradation by carboxypeptidase. Chymotrypsin degrades 3-Acpc-ATII and 5-Acpc-ATII but not 4-Acpc-ATII. The action of leucine-aminopeptidase is not influenced by substituting Acpc to each one of the first five amino acids composing the molecule of angiotensin.The possible implications of these findings for the peptide-receptor interaction is discussed.
