PT-141 (bremelanotide) is a synthetic cyclic heptapeptide and a metabolite (the deaminated, C-terminal free-acid analogue) of melanotan II. In research it is characterised as a melanocortin-receptor agonist with activity at MC1R, MC3R and MC4R, used as a tool to probe central and peripheral melanocortin signalling.
