PT-141, also known as bremelanotide, is a cyclic analog of the melanocortin peptide Melanotan II, developed as a non-selective agonist at melanocortin receptors with particular activity at MC4R and MC1R. Unlike its parent compound, bremelanotide acts primarily through central melanocortin pathways rather than peripheral pigmentation pathways, making it a frequent subject in neuroendocrine and behavioral research. The lactam bridge between the Asp and Lys residues constrains the peptide into its bioactive conformation.
BENEFITS
