BioAssay: AID 569837

Antagonist activity at human RXRalpha LBD by cell based luciferase reporter gene assay

Estrogen-related receptor alpha (ERRalpha) is an orphan nuclear receptor that has been functionally implicated in the regulation of energy homeostasis. Herein is described the development of diaryl ether based thiazolidenediones, which function as selective ligands against this receptor. Series optimization provided several potent analogues that inhibit the recruitment of a coactivator peptide more ..

Title: Identification of diaryl ether-based ligands for estrogen-related receptor alpha as potential antidiabetic agents.

Abstract: Estrogen-related receptor alpha (ERRalpha) is an orphan nuclear receptor that has been functionally implicated in the regulation of energy homeostasis. Herein is described the development of diaryl ether based thiazolidenediones, which function as selective ligands against this receptor. Series optimization provided several potent analogues that inhibit the recruitment of a coactivator peptide fragment in in vitro biochemical assays (IC(50) < 150 nM) and cellular two-hybrid reporter assays against the ligand binding domain (IC(50) = 1-5 muM). A cocrystal structure of the ligand-binding domain of ERRalpha with lead compound 29 revealed the presence of a covalent interaction between the protein and ligand, which has been shown to be reversible. In diet-induced murine models of obesity and in an overt diabetic rat model, oral administration of 29 normalized insulin and circulating triglyceride levels, improved insulin sensitivity, and was body weight neutral. This provides the first demonstration of functional activities of an ERRalpha ligand in metabolic animal models.
