产品描述:
A-192621 is a potent, nonpeptide, orally active and selective endothelin B (ETB) receptor antagonist with an IC50 of 4.5 nM and a Ki of 8.8 nM. The selectivity of A-192621 is 636-fold higher than ETA (IC50 of 4280 nM and Ki of 5600 nM). A-192621 promotes apoptosis in PASMCs. A-192621 alos causes elevation of arterial blood pressure and an elevation in the plasma ET-1 level[1][2][3].
A-192621 (1-100 μM; 48 hours; PASMCs) treatment markedly reduces the cell viability of PASMCs in a dose-dependent manner[2].A-192621 (1-100 μM; 48 hours; PASMCs) treatment significantly increases the caspase-3/7 activity and cleaved caspase-3 expression in PASMCs. A-192621 induces apoptosis in a dose-dependent manner and increases the cells' susceptibility to apoptosis by Doxorubicin treatment[2]. Cell Viability Assay[2] Cell Line: Pulmonary arterial smooth muscle cells (PASMCs) with Doxorubicin
A-192621 (30-100 mg/kg; oral administration; daily; for 3 days; male Sprague-Dawley rats) treatment inhibits both dilatory and pressor responses induced by S6c mediated by ETB with an ED50 value of 30 mg/kg, and failed to inhibit the ET-1-induced pressor response mediated by ETA. A-192621 alone causes elevation of arterial blood pressure and an elevation in the plasma ET-1 level in the conscious normotensive rat[3]. Animal Model: Male Sprague-Dawley rats (250-350 g)[3]
