    Product Description

    Angiotensin II is a peptide hormone that regulates blood pressure and fluid balance, contributing to hypertension, atherosclerosis, left ventricular hypertrophy, myocardial infarction, and heart failure. It binds with high affinity to two distinct receptors: AT1R (angiotensin type 1 receptor) and AT2R (angiotensin type 2 receptor). AT1R activation facilitates the ‘classical’ effects, including vasoconstriction, cellular growth, and proliferation, whereas AT2R activation offsets AT1R-mediated actions, promoting vasodilatation, apoptosis, and anti-growth effects.1 PD 123319 is a selective, nonpeptide AT2R antagonist (IC50 = 5.6 nM vs. 100 nM for AT1R).1,2 It has been used to selectively examine the specific roles for AT1R and AT2R in hypertensive and other vascular research-related models.3,4
