Institutional GradePT-141 (Bremelanotide) | Research Use Only Synthetic Cyclic Heptapeptide | ≥98% Purity | Lyophilized Powder CAS: 189691-06-3 Sequence: Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH, featuring a lactam bridge between the aspartic acid and lysine residues Molecular Formula: C₅₀H₆₈N₁₄O₁₀ Molecular Weight: 1025.2 g/mol Also known as: Bremelanotide, Vyleesi (FDA-approved brand), MTP-II metabolite For Research Use Only. Not intended for human or veterinary use. PT-141 is a synthetic analogue of α-melanocyte-stimulating hormone (α-MSH) used in laboratory research to study melanocortin receptor pathways. It is a cyclic heptapeptide cyclized via a lactam bridge between Asp and Lys residues. This cyclic structure confers significantly greater metabolic stability compared to linear α-MSH analogs. Bremelanotide acts as a non-selective agonist of the melanocortin receptors, primarily MC3R and MC4R, present in the central nervous system. These receptor subtypes are most highly expressed in the hypothalamus and limbic system.
