PT-141

PT-141 (Bremelanotide, CAS 189691-06-3) is a synthetic cyclic heptapeptide supplied for laboratory and analytical research use only. It is a structural analogue of alpha-melanocyte-stimulating hormone (α-MSH) and a metabolite of Melanotan II.

Research background

PT-141 is characterised in the literature as a melanocortin receptor agonist with reported activity at the MC3 and MC4 receptor subtypes. Unlike Melanotan II, it is studied primarily for its central-nervous-system signalling profile rather than pigmentation pathways. Investigators typically examine it in the context of melanocortin receptor pharmacology, hypothalamic signalling and comparative agonist selectivity across the melanocortin receptor family.
