(Sar1)-Angiotensin II
(Sar1)-Angiotensin II, an analogue of Angiotensin II, is a specific agonist of angiotensin AT1 receptor. (Sar1)-Angiotensin II binds to brain membrane-rich particles, with a Kd of 2.7 nM. (Sar1)-Angiotensin II can stimulate protein synthesis and cell growth in embryonic chick myocytes[3].
