Biological Activity
Potent endogenous vasoconstrictor peptide; derivative of angiotensin (Ang) II. Elicits pressor and renal vasoconstrictor effects in rodents via the AT1 receptor; inhibited by Candesartan (Cat. No. 4791) but not by AT2 receptor ligands in vivo. Displays a similar affinity for AT1 and AT2 receptors as angiotensin II in vitro (Ki values are 1.6 and 2.3 nM at AT1 and AT2 receptors); also increases inositol phosphate accumulation with a similar potency to Ang II (EC50 = 6.7 nM).
