Melanocortin Receptor Agonist
PT-141 (Bremelanotide) is a nonapeptide derived from Melanotan II. It acts as an agonist at the melanocortin MC3-R and MC4-R receptors within the central nervous system. Unlike vascular-targeting drugs, PT-141 acts strictly on neurological pathways to modulate sexual arousal responses in mammalian trials.
Research Applications
