About this compound
PT-141 (Bremelanotide) is a cyclic heptapeptide with preferential affinity for MC3R and MC4R over MC1R. Unlike Melanotan-2, it shows minimal pigmentation pathway activity and primarily engages CNS melanocortin circuitry. Activates cAMP signaling in hypothalamic cell models. MC3R/MC4R vs MC1R selectivity studies, hypothalamic melanocortin pathway research, CNS receptor binding assays, and comparative pharmacology panels alongside Melanotan-2.
