PT-141 10MG

PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide melanocortin receptor agonist derived from the Melanotan II scaffold through enzymatic modification. The peptide, with the sequence Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH, exhibits preferential agonist activity at the MC3R and MC4R melanocortin receptor subtypes, which are prominently expressed in the central nervous system and play integral roles in the regulation of neuroendocrine signaling, autonomic function, and behavioral neurocircuitry. These receptor subtypes have been the focus of intensive research in hypothalamic biology and limbic system neuroscience.
