Discovery and optimization of a novel class of orally active nonpeptidic endothelin-A receptor antagonists

J Med Chem. 1996 May 24;39(11):2123-8. doi: 10.1021/jm960274q.

Abstract

A novel class of endothelin-A receptor ligands was discovered by high-throughput screening. Lead structure optimization led to highly potent antagonists which can be synthesized in a short sequence. The compounds are endothelin-A-selective, are orally available, and show a long duration of action.
