What is PT-141?
PT-141, also known as bremelanotide, is a synthetic cyclic heptapeptide analog of α-melanocyte-stimulating hormone (α-MSH) that exerts its activity primarily through melanocortin receptors MC3R and MC4R, which are expressed in the central nervous system. The mechanism of action involves activation of hypothalamic neurons implicated in sexual response pathways, distinguishing PT-141 from peripheral vasodilators or hormone-based agents. In male clinical subjects, subcutaneous administration of PT-141 demonstrated a dose-dependent increase in erectile responses. The pharmacokinetic profile revealed that maximum plasma concentrations were achieved within approximately 1 hour post-dose, with a half-life ranging from 1.9 to 2.7 hours. The pharmacodynamic effect was observable at doses as low as 1.0 mg, with enhanced response durations at higher doses, confirming central melanocortin receptor-mediated activity. In female preclinical models, PT-141 selectively facilitated sexual solicitation behavior through MC3R/MC4R activation, further supporting its classification as a centrally acting melanocortin receptor agonist.
