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 (Ki=0.9 nM) and selective for the ETA receptor, approximately equivalent to 1.

Compounds of the formula STR1 inhibit the activity of endothelin. The symbols are defined as follows: R 1, R 2, R 3 and R 4 are each directly bonded to a ring carbon and are each independently(a) hydrogen;(b) alkyl, alkenyl, alkynyl, alkoxy,
