CAS#: 210891-04-6

Description: Edonentan, also known as BMS-207940, is a highly potent and orally active ET(A) selective antagonist. Edonentan is an extremely potent (ET(A) K(i) = 10 pM) and selective (80,000-fold for ET(A) vs ET(B)) antagonist. It is also 150-fold more potent and >6-fold more selective than BMS-193884. The bioavailability of Edonentan was 100% in rats and the systemic clearance and volume of distribution are higher than that of BMS-193884. In rats, intravenous Edonentan blocks big ET pressor responses with 30-fold greater potency than 1. After oral dosing at 3 micromol/kg, Edonentan displays enhanced duration relative to BMS-193884.
