Abstract

Potent small molecule antagonists of the urotensin receptor are described. These inhibitors were derived via systematically deconstructing a literature inhibitor to understand the basic pharmacophore and key molecular features required to inhibit the protein receptor. The series of benzylamine and benzylsulfone antagonists herein reported display a combination of nanomolar molecular and cellular potency as well as acceptable in vitro permeability and metabolic stability.
