Compound: PT-141 (Bremelanotide)
Concentration: 10mg per vial
Format: Lyophilized White Powder (Strictly for In-Vitro Laboratory Use)
Sequence: Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH
Chemical Classification: Melanocortin Receptor Agonist
Chemical Profile: PT-141 is a synthetic cyclic heptapeptide derived from the alpha-melanocyte-stimulating hormone (alpha-MSH) framework. Structurally, it incorporates an N-acetylated norleucine and D-phenylalanine to enhance receptor selectivity and metabolic stability. Unlike its parent compound (Melanotan II), PT-141 has been optimized to selectively bind to central melanocortin receptors (MC3R and MC4R) while minimizing affinity for the MC1R receptors associated with melanogenesis (pigmentation). The cyclic structure confers resistance to enzymatic degradation, resulting in a predictable pharmacokinetic profile in research environments.
