Used as a potent and selective antagonist for the angiotensin II receptor subtype 1 (AT1), this compound plays a key role in cardiovascular research. It helps in studying mechanisms related to blood pressure regulation and hypertension. Due to its high affinity for AT1 receptors, it is utilized in pharmacological assays to block angiotensin II-induced vasoconstriction, enabling analysis of receptor function and signaling pathways. Its structure allows for good membrane permeability, making it suitable for in vitro and in vivo studies. Researchers also use it as a reference compound when developing new antihypertensive agents or evaluating the efficacy of receptor blockers.
