the angiotensin ii receptor type 1

TRV120027 TFA is a β-arrestin-1-biased agonist of the angiotensin II receptor type 1 (AT1R) and engages ß-arrestins while blocking G-protein signaling.

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.

TRV055 is a Gq-biased ligand of the angiotensin II receptor type 1 (AT1R). TRV055 is efficacious in stimulating cellular Gq-mediated signaling. TRV055 can be used to develop the Gq-biased AT1R agonists.

TRV056 is a Gq-biased agonist of the angiotensin II type 1 receptor (AT1R), demonstrating efficacy in stimulating Gq-mediated cellular signaling. It can serve as a foundation for the development of Gq-biased AT1R agonists.

Angiotensin II human TFA is a potent vasoconstrictor in the renin-angiotensin system that regulates blood pressure through interactions with AT1R and AT2R receptors. It activates sympathetic nerve activity, promotes aldosterone synthesis and renal function, induces proliferation of vascular smooth muscle cells, and enhances type I and III collagen production in fibroblasts, leading to vascular and myocardial thickening and fibrosis. It also triggers apoptosis and promotes capillary formation, making it suitable for establishing models of cardiac hypertrophy, hypertension, and abdominal aortic aneurysm.

TRV055 hydrochloride, a Gq-biased ligand and G-protein-biased agonist of the angiotensin II receptor type 1 (AT1R), effectively stimulates cellular Gq-mediated signaling [1].

(Sar1,Ile4,8)-Angiotensin II is a functionally selective agonist for the angiotensin II type 1 receptor (AT1R), enhancing insulin-stimulated signaling of the insulin receptor (IR) and glycogen synthesis, and boosting the insulin-induced phosphorylation of Akt and GSK3α β [1].

TRV120027 is a β-arrestin-1-biased agonist of the angiotensin II receptor type 1. TRV120027 inhibits angiotensin II-mediated vasoconstriction and increases cardiomyocyte contractility.

TRV-120027 acetate is a β-arrestin-1-biased agonist of the angiotensin II receptor type 1 (AT1 receptor) and engages -arrestins while blocking G-protein signaling.
