PT-141, also known as Bremelanotide, is a synthetic melanocortin peptide derived from the α-MSH (alpha-melanocyte–stimulating hormone) sequence. In research settings, PT-141 functions as an MC4R and MC1R receptor agonist, activating central melanocortin pathways involved in neural signaling, autonomic function, and behavioral modulation.
