Biphenylsulfonamide Endothelin Receptor Antagonists. Part 3: Structure–Activity Relationship of 4′-Heterocyclic Biphenylsulfonamides
摘要:
A number of 4'-heterocyclic biphenylsulfonamide derivatives, formally derived from BMS-193884 (1) by replacing the oxazole ring with other heterocyclic rings, are potent and selective endothelin A (ETA) receptor antagonists. Among the analogues examined, the pyrimidine derivative 18 is the most potent (K-i = 0.9 nM) and selective for the ETA receptor, approximately equivalent to 1. (C) 2002 Bristol-Myers Squibb Company.
