A synthetic small-molecule pan-agonist of estrogen-related receptors (ERRα, ERRβ, and ERRγ), with highest potency for ERRγ. In research settings, it acts as an exercise mimetic by activating metabolic pathways similar to intense aerobic training. It is investigated for its ability to promote mitochondrial biogenesis, enhance fatty acid oxidation, and improve cellular energy efficiency without altering food intake.
