What is SLU-PP-332?
SLU-PP-332 is a triple ERR agonist — the first small molecule to activate all three estrogen-related receptor isoforms with similar potency. ERRs are nuclear receptors that regulate oxidative metabolism, mitochondrial function, and fiber-type composition in skeletal and cardiac muscle. The compound is investigated as an 'exercise pill' candidate — a pharmacological mimic of the cellular adaptations driven by endurance training.
