GW590735 is primarily used in research settings as a potent and selective agonist for the liver X receptor (LXR). It is employed to study the role of LXRs in lipid metabolism, inflammation, and immune responses. In preclinical studies, it has shown potential in modulating cholesterol homeostasis, making it a candidate for investigating therapeutic strategies for atherosclerosis and other metabolic disorders. Additionally, GW590735 is utilized to explore its effects on gene regulation and its potential anti-inflammatory properties, particularly in conditions like autoimmune diseases. Its application extends to understanding the molecular mechanisms of LXR pathways in various biological processes.
