About Melanotan II
Melanotan II is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH), with the structure Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2. The cyclic ring, formed by a lactam bridge, makes it far more resistant to enzymatic breakdown than native α-MSH.
Canada Research Labs supplies Melanotan II as 10mg of lyophilized powder in a 3 mL glass vial, packed and shipped from Ontario.
See our Melanotan II research overview.
Research background
Melanotan II was developed at the University of Arizona in the late 1980s and early 1990s as part of research into stable α-MSH analogs. It is a non-selective agonist of the melanocortin receptors, binding MC1R, MC3R, MC4R and MC5R.
Because it activates several melanocortin receptor subtypes, Melanotan II is used as a reference compound in laboratory studies of melanocortin receptor pharmacology, including MC1R signaling in melanocyte cell cultures. Its close structural relative PT-141 differs only at the C-terminus and is studied for its activity at a narrower set of receptors.
