生物活性:
Darusentan (Lu-135252) is a selective endothelin receptor A (ET-A) receptor antagonist, which binds with a Ki of 1.4 nM to the ET-A receptor and a Ki of 184 nM to ET-B receptor, respectively with a 100-fold selectivity for ETA rather than ETB receptors. Darusentan competes for radiolabeled endothelin binding in rat aortic vascular smooth muscle cells (RAVSMs) membranes with single-site kinetics, exhibiting a Ki of 13 nM.
体内研究:
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.Animal Model:Twenty-four (eight per group) male Sprague Dawley rats weighing 175±200 g
Dosage:30 mg/kg
Administration:Administered orally in rat food for weeks 3 and 4
Result:Reversed aortic alterations produced by infusion of Norepinephrine (2.5 μg/kg).
体外研究:
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.
