Melanotan II (MT-2)

Synthetic cyclic melanocortin peptide

Melanotan II (MT-2) is a synthetic cyclic peptide belonging to the melanocortin class. In the scientific literature it is investigated in pigmentation and melanocortin-receptor signaling research models. This page offers neutral background about the molecule as a research material and is not medical guidance and not for human or veterinary use.

Classification and structure

Classification and structure: MT-2 is a cyclic analog derived from the alpha-MSH pharmacophore, distinguished from linear analogs by its ring-constrained structure. It is studied as a non-selective agonist across several melanocortin receptor subtypes, which is of interest in receptor-selectivity research. Describing a compound as 'studied in' an area is a statement about where scientific attention has gone, not a claim that it produces any result.

Areas of research

MT-2 appears across several areas of the research literature.

• Melanocortin receptor research — Investigated in models of agonism across multiple melanocortin receptor subtypes.
• Pigmentation research — Appears in the literature on melanin biology and pigmentation models.
• Peptide chemistry — Studied as an example of cyclization in structure-activity research.

As always in this library, describing a compound as “studied in” an area is a statement about where scientific attention has gone — not a claim that it produces any result in humans or animals.
