SLU-PP-332: Exercise Mimetic Drug for Endurance and Fat Loss

Introduction: Developing SLU-PP-332 as an Exercise Mimetic
SLU-PP-332 is being called an "exercise in a pill"—and early research shows it might deliver. In mice, it boosts endurance, burns fat, and increases cellular energy—all without extra movement.
SLU-PP-332 is a synthetic molecule, also referred to as a "pan-agonist," that binds to and activates estrogen-related receptors (ERRs). These receptors—specifically ERRα (alpha), ERRβ (beta), and ERRγ (gamma)—effectively preserve the balance of energy in our cells. To maintain constant energy supply in the body, they control basic metabolic pathways like how lipids are burned, how glucose is used, and how mitochondria are generated.
Because these tissues have such high energy demands, you find the highest ERR expression in the brain, heart, and muscles. Activating these receptors with SLU-PP-332 increases mitochondrial activity and metabolic efficiency, enabling cells to function more like they do during exercise.
