ang-1-7 receptor

AVE 0991 competes for high-affinity binding of [125I]-Ang-(1-7) to bovine aortic endothelial cell membranes, with IC50 of 21±35 nM. AVE 0991 sodium salt is a nonpeptide and orally active Ang-(1-7) receptor Mas agonist.

Alamandine can be formed from angiotensin A by action of ACE-2 or directly from angiotensin-(1-7) by decarboxylation of its aspartate residue. The angiotensin A analog produces effects resembling those of Ang II (1-7). However, it acts independently of the two known vasodilators receptors of the RAS (Mas and angiotensin II type 2). To produce its effects, alamandine binds to the Mas-related receptor, MrgD. A novel orally active formulation of alamandine produced a long-term antihypertensive effect in spontaneously hypertensive rats and cardioprotective effects. These novel findings will be helpful for developing a new understanding of the RAS, a key regulator of blood pressure and fluid balance. The heptapeptide could serve as a model peptide, e.g. in the development and evaluation of analytical methods.

Angiotensin (1-7) (ASP-ARG-VAL-TYR-ILE-HIS-PRO) is a synthetic heptapeptide identical to endogenous angiotensin-(1-7) , inhibits purified canine ACE activity (IC50=0.65 μM) with vasodilator and antiproliferative activities.

AVE 0991, a nonpeptide analog of angiotensin-(1-7) [Ang-(1-7)], is an orally active Mas agonist with inhibitory effects on [125I]-Ang-(1-7) binding to bovine aortic endothelial cell membranes, and inhibits astrocyte-mediated neuroinflammation in Alzheimer's disease by enhancing autophagy.
