Angiotensin A is an angiotensin II type 1 (AT1) and AT2 receptor agonist and active metabolite of the peptide hormone angiotensin II .1 It is formed from angiotensin II via decarboxylation of the N-terminal aspartate residue. Angiotensin A binds to AT1 and AT2 receptors in HEK293 cells expressing the rat receptors (IC50s = 0.29 and 0.12 nM, respectively, in radioligand binding assays) and induces calcium mobilization in vascular smooth muscle cells (VSMCs; EC50 = 100 nM). It increases the perfusion pressure in isolated perfused rat kidney (EC50 = 443 nM), an effect that can be reversed by the AT1 antagonist EXP-3174 . The ratio of angiotensin A to angiotensin II (Ang A/Ang II) in the plasma is increased in patients with end-stage renal failure and serum levels of angiotensin A are decreased in patients with pulmonary arterial hypertension.1,2
