PT-141: Central Nervous System Mechanism and Melanocortin Signaling

Molecular rendering of a melanocortin peptide agonist docking into a 7-transmembrane GPCR on a neuronal cell membrane.

PT-141 (bremelanotide) is a synthetic melanocortin receptor agonist that acts within the central nervous system. By activating hypothalamic MC3R and MC4R p
