AT1 Receptor Agonist

Buloxibutid (AT2 receptor agonist C21) is an orally active, selective angiotensin II type 2 receptor (AT2R) agonist, with a K_i value of 0.4 nM for porcine AT2R. Buloxibutid exerts effects such as vasodilation, anti-inflammation, anti-fibrosis (promoting the expression of collagenase MMP-13) and tissue repair mainly by activating the NO/cGMP pathway, inhibiting the pro-proliferative MAPK signaling, and suppressing the pro-fibrotic TGF-β/Smad pathway as well as the inflammatory NF-κB pathway. Buloxibutid can be used in research related to idiopathic pulmonary fibrosis, hypertension, and systemic sclerosis.

TRV120027, a β-arrestin-1-biased agonist of the angiotensin II receptor type 1 (AT1R), engages β-arrestins while blocking G-protein signaling. TRV120027 induces acute catecholamine secretion through cation channel subfamily C3 (TRPC3) coupling, promotes the formation of a macromolecular complex composed of AT1R-β-arrestin-1-TRPC3-PLCγ at the plasma membrane. TRV120027 inhibits angiotensin II-mediated vasoconstriction and increases cardiomyocyte contractility. TRV120027 has the potential for the acute decompensated heart failure (ADHF) treatment.

TRV055 (TRV120055) is a G protein-biased agonist of angiotensin II type 1 receptors (AT1Rs). TRV120055 induces fibroblast proliferation, overexpression of collagen I and α-SMA, and stress fibre formation in human cardiac fibroblasts. TRV055 activates AT1 receptor/Gαq-mediated signaling pathways, upregulates TGF-β1 and p-ERK1/2. TRV055 induces collagen secretion in adult rat myofibroblasts at a level comparable to Ang II. TRV055 can be used to study the role of G protein-biased signaling of AT1Rs in regulating fibrotic responses^[1]

RV055 hydrochloride can be used to study the role of G protein-biased signaling of AT1Rs in regulating fibrotic responses^[1]

(Sar1,Ile4,8)-Angiotensin II is a functionally selective angiotensin II type 1 receptor (AT1R) agonist. (Sar1,Ile4,8)-Angiotensin II potentiates insulin-stimulated insulin receptor (IR) signaling and glycogen synthesis. (Sar1,Ile4,8)-Angiotensin II potentiates insulin-stimulated phosphorylation of Akt and GSK3α/β.

(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 K_d of 2.7 nM. (Sar1)-Angiotensin II can stimulate protein synthesis and cell growth in embryonic chick myocytes.

AT1R-agonist-1 is an angiotensin II type 1 receptor (AT1R) agonist with a K_i value of 1.4 nM. AT1R-agonist-1 exhibits low Gαq activity, retains β-arrestin recruitment function, and accesses the deep allosteric pocket inside AT1R via its flexible side chain. AT1R-agonist-1 possesses positive inotropic effects (enhancing cardiac contractile function) and causes almost no increase in blood pressure. AT1R-agonist-1 can be used for research on conditions such as refractory cardiogenic shock.

Buloxibutid (AT2 receptor agonist C21) hydrochloride is an orally active, selective angiotensin II type 2 receptor (AT2R) agonist, with a K_i value of 0.4 nM for porcine AT2R. Buloxibutid hydrochloride exerts vasodilatory, anti-inflammatory, antifibrotic (promoting the expression of collagenase MMP-13) and tissue repair effects mainly by activating the NO/cGMP pathway, inhibiting the pro-proliferative MAPK signaling, and suppressing the pro-fibrotic TGF-β/Smad pathway and inflammatory NF-κB pathway. Buloxibutid hydrochloride can be used in research related to idiopathic pulmonary fibrosis, hypertension, systemic sclerosis and other conditions.
