Description
PT-141 (bremelanotide) is a cyclic heptapeptide derived from Melanotan II, engineered for greater selectivity at the MC4R melanocortin receptor subtype over MC1R. Research on PT-141 has focused on central nervous system MC4R activation in the hypothalamus, a pathway implicated in the regulation of sexual arousal independent of the vascular mechanisms targeted by traditional PDE5-inhibitor research compounds. Clinical-stage research on the parent program characterized its receptor binding affinity and dose-response relationship, distinguishing it pharmacologically from its non-selective precursor.
