Description
PT-141 (Bremelanotide) Peptide Overview
PT-141, also known as bremelanotide, is a synthetic cyclic peptide and melanocortin-receptor agonist derived from the peptide Melanotan II. Unlike pigment-focused analogs, PT-141 is studied in research for its action on central nervous-system melanocortin pathways.
Melanocortin Receptor Activation
PT-141 activates melanocortin receptors, primarily MC4R and MC1R. Its research interest centers on MC4R signaling in the central nervous system rather than peripheral pigmentation.
Central Arousal Pathway Research
The most studied aspect of PT-141 is its effect on hypothalamic melanocortin pathways involved in arousal and sexual-response signaling, investigated in neurobehavioral research models.
Distinct Mechanism
Because PT-141 acts through central neural pathways rather than the vascular system, it represents a distinct mechanism of interest in melanocortin research.
