Discovery and development of an endothelin A receptor-selective antagonist PD 156707.

Abstract

PD 156707 is a highly potent, selective antagonist of the ETA receptor that has demonstrated efficacy in a number of different disease models. The next few years will be exciting in the field of ET research as several compounds progress through clinical development. It is our hope that the efficacy that data demonstrated to date with PD 156707 will some day be translated into real hope for the patients who are waiting beyond the confines of our research laboratories.
