PT-141

For Research Use Only | Not for Human or Veterinary Use

Description:
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide melanocortin receptor agonist derived from the metabolite of Melanotan II. In preclinical laboratory research, PT-141 is investigated for its selective activity at melanocortin receptors MC3R and MC4R, distinguishing it from broader melanocortin agonists. The peptide’s cyclic lactam structure and C-terminal free acid (rather than amide) differentiate it structurally from its parent compound Melanotan II. PT-141 serves as a key pharmacological tool for studying melanocortin receptor-mediated central nervous system pathways, particularly those involved in sexual function, arousal signaling, and hypothalamic neuroendocrine regulation.
