PT-141

PT-141, also known as Bremelanotide, is a synthetic peptide derived from Melanotan 2. This cyclic heptapeptide acts as a melanocortin receptor agonist with particular affinity for MC3R and MC4R. Researchers study PT-141 for its effects on sexual behavior, arousal mechanisms, and melanocortin signaling in laboratory settings.

Scientific research on PT-141 examines its effects on melanocortin receptor activation in the central nervous system. Studies focus on its influence on MC3R and MC4R receptors in hypothalamic regions, effects on sexual arousal pathways, dopaminergic signaling, and behavioral responses. Researchers investigate its mechanisms involving central melanocortin system activation and neural circuits related to motivation and arousal in experimental models.
