MT-2 — Cyclic Melanocortin Receptor Agonist

MT-2 (Melanotan II) is a synthetic cyclic lactam analog of α-melanocyte-stimulating hormone (α-MSH). Structural modifications — including cyclization via a lactam bridge, D-amino acid substitution, and truncation to seven residues — yield a peptide with dramatically enhanced metabolic stability, higher receptor-binding affinity, and broader melanocortin subtype engagement than the native linear hormone.

Mechanism of Action

MT-2 acts as a non-selective agonist across melanocortin receptor subtypes MC1R through MC5R. At MC1R in epidermal melanocytes, it activates the cAMP/PKA/MITF axis to drive eumelanin synthesis via tyrosinase upregulation. MC3R and MC4R engagement in the hypothalamus modulates appetite, energy balance, and central melanocortin signaling — the basis of a large research literature on central melanocortin signaling. The cyclic architecture makes MT-2 resistant to the enzymatic degradation that rapidly inactivates linear α-MSH.
