Melanotan II acetate is an agonist of melanocortin receptor 1 (MC1R), MC3R, MC4R, and MC5R. It has been shown to improve recovery of sciatic nerve function after mechanical injury and increase cisplatin-induced decreases in sensory nerve conduction velocity. Melanotan II acetate increases oxygen consumption and protein levels of uncoupling protein 1 (UCP1) in brown adipose tissue homogenates and decreases food intake, body weight, and serum levels of leptin, glucose, insulin, and cholesterol.
