描述 | The ETB receptor is expressed on vascular endothelial cells where it induces endothelial-dependent vasodilatation through NO production and clearance of circulating ET-1[1]. IRL 2500, a potent endothelin receptor antagonist, inhibits the binding of [125I]-endothelin-1 (ET-1) to human ETB (IC50 1.3 ± 0.2 nM) and ETA (IC50 94 ± 3 nM) receptors expressed in transfected Chinese hamster ovary (CHO) cells. In in vitro studies, IRL 2500 inhibited the sarafotoxin S6c (STX6c)-mediated contraction of the dog saphenous vein (pKb 7.77) and the STX6c-induced relaxation of the preconstricted rabbit mesenteric artery (pKb 6.92). In the anesthetized rat, IRL 2500 (10 mg/kg, i.v.) inhibited the initial transient decrease in mean arterial pressure (MAP) induced by the ETB-selective agonist IRL 1620 (0.5 nmol/kg, i.v.). IRL 2500 also attenuated the IRL 1620-mediated increase in renal vascular resistance (RVR) in the anesthetized rat[2]. |
