Melanotan 2 (MT2)

Melanotan 2 (MT2) is a synthetic cyclic heptapeptide (Ac-Nle-c[Asp-His-D-Phe-Arg-Trp-Lys]-NH₂) used in receptor binding and signal transduction studies. It explores MC1R–MC5R-mediated cAMP activation and GPCR desensitization mechanisms. MT-II serves as a research model for peptide–receptor pharmacology and neuroendocrine signaling dynamics. It is intended for research use only and not for human consumption.
