A-779 is a peptide antagonist of the Mas receptor, also known as the angiotensin (1-7) (Ang (1-7)) receptor (IC50 = 0.3 nM in a radioligand binding assay).1 It does not compete with angiotensin 1 (AT1) and AT2 receptor agonists for binding in adrenocortical membranes when used at a concentration of 1 µM and exhibits an IC50 value greater than 10 µM in adrenomedullary membranes.2 In vitro, A-779 inhibits Ang (1-7)-induced release of arachidonic acid from CHO cells transfected with Mas.1 A-779 (0.01 mg/kg) prevents the antidiuretic effects of Ang (1-7) in water-loaded rats. It also inhibits the Ang (1-7)-induced decrease in mean arterial pressure (MAP) when administered by microinjection into the nucleus of the solitary tract with no effect on basal MAP. A-779 increases urine flow rate and sodium excretion in male, but not female, rats when AT1 and AT2 receptors are blocked by the selective antagonists losartan and PD 123319 , respectively.3
