The synthesis and structure activity relationships of a series of sulfonamide endothelin antagonists are described. In the course of our modification studies, we discovered ET(B) selective antagonists. The most potent compound 15f displays IC50 values of 1.7 microM and 0.002 microM to ET(A) and ET(B) receptors, respectively.
