Bremelanotide - cyclic heptapeptide MC3R/MC4R agonist for central melanocortin pathway research. Deamidated analog of MT-2.
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide analog of alpha-MSH and a structural variant of Melanotan II, differing by a free C-terminal carboxylic acid group instead of the C-terminal amide. PT-141 acts as an agonist at MC3R and MC4R in the central nervous system, making it an important tool for studying melanocortin receptor subtypes and CNS pathway localization.
