Discovery and optimization of a series of liver X receptor antagonists.

ABSTRACT

The present report describes our efforts to convert an existing LXR agonist into an LXR antagonist using a structure-based approach. A series of benzenesulfonamides was synthesized based on structural modification of a known LXR agonist and was determined to be potent dual liver X receptor (LXR α/ß) ligands. Herein we report the identification of compound 54 as the first reported LXR antagonist that is suitable for pharmacological in vivo evaluation in rodents.
