摘要:
The synthesis and structure activity relationships of a series of sulfonamide endothelin antagonists are described. In the course of our modification studies, we discovered ETB selective antagonists. The most potent compound 15f displays IC50 values of 1.7 mu M and 0.002 mu M to ETA and ETB receptors, respectively. (C) 2000 Elsevier Science Ltd. All rights reserved.
