Darusentan 是大动脉和小动脉内皮素信号传导和功能的有效抑制剂。

Darusentan is a potent inhibitor of endothelin signaling and function in both large and small arteries.(In Vitro):Darusentan ((S)-Darusentan) competes for radiolabeled endothelin binding in rat aortic vascular smooth muscle cells (RAVSMs) membranes with single-site kinetics, exhibiting a Ki=13 nM. In isolated endothelium-denuded rat aortic rings, Darusentan inhibits endothelin-induced vascular contractility with a pA2=8.1±0.14. Darusentan ( 0.001-1μM) inhibits ET-1-induced signaling in cultured RAVSMs.(In Vivo):Darusentan (30 mg/kg per day orally for weeks 3 and 4) reverses aortic alterations produced by infusion of Norepinephrine (2.5 μg/kg per min subcutaneously for 2 and 4 weeks) in male Sprague Dawley rats.
