Selective ERRα inverse agonist (IC50 = ~400 nM). Displays no antagonist activity at ERRγ or ERα at concentrations below 10 μM. Interferes with PPARγ coactivator-1α (PGC-1α)/ERRα-dependent signaling: inhibits PGC-1α induction of ERRα and MAO-B gene expression and downregulates the constitutive transcriptional activity of ERRα in numerous cell lines. Purity 99%. MW (observed): 596.42
