Description: Potent AT1 inverse agonist; antihypertensive
Chemical Name: 2-Ethoxy-1-[[2'-(4,5-dihydro-5-oxo-1,2,4-oxadiazol-3-yl)biphenyl-4-yl]methyl]benzimidazole-7-carboxylic acid
Purity: ≥98% (HPLC)
Biological Activity
Potent angiotensin II type 1 (AT1) receptor inverse agonist (IC50 = 2.6 nM at the human AT1 receptor). Inhibits angiotensin II-induced IP1 accumulation in COS-7 cells; decreases maximal contraction of rabbit aortic strips in a concentration-dependent manner (pD'2 = 9.9). Antihypertensive; prevents vascular cell proliferation and expression of PAI-1.
Compound Libraries
Azilsartan is also offered as part of the Tocriscreen FDA-Approved Drugs. Find out more about compound libraries available from Tocris.
