PT-141
PT-141 (Bremelanotide) is a cyclic heptapeptide and metabolite of Melanotan II that acts as a non-selective melanocortin receptor agonist, with notable affinity for the MC3R and MC4R subtypes. Unlike peripherally acting vasoactive compounds, it works centrally through the nervous system, which makes it a distinctive tool for neuroendocrine and central-arousal pathway research.
