Description
About PT-141
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide and an agonist at melanocortin receptors MC3R and MC4R, which are expressed primarily in the central nervous system. It is a metabolite of Melanotan II and has a molecular formula of C50H68N14O10 with a molecular weight of 1025.2 g/mol.
PT-141 is used in preclinical and in vitro research investigating melanocortin receptor pharmacology and central nervous system signalling. Studies have characterised its binding affinity and selectivity at MC3R and MC4R, and it has been used as a research tool in models examining receptor-mediated neurological pathways.
