    PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide analogue of α-melanocyte stimulating hormone. It acts as a non-selective agonist at melanocortin receptors with highest affinity for MC3R and MC4R. Research has focused on its effects on central-nervous-system signaling pathways associated with sexual-arousal behavior in preclinical models.

    PT-141 is studied in melanocortin-receptor pharmacology, CNS signaling research, and as a research tool for investigating MC3R/MC4R-mediated pathways.
