Melanotan 2 // The Melanocortin Dossier: One Peptide, Five Receptors
Why MT-2 remains a core tool for studying melanocortin-pathway biology.
EuroVials Research Desk // Editorial · Skin & Longevity
Melanotan 2 is a synthetic analogue of α-MSH, built in academic research to be a more stable probe of the melanocortin system. Its non-selectivity across receptor subtypes is exactly what makes it a broad research tool.
The Molecule From the Melanocortin Program
MT-2 came out of academic work (University of Arizona) on the melanocortin system, engineered from the natural α-MSH hormone for greater receptor-binding stability. It's a probe first, a product second — which is why the literature treats it as a way to study a pathway, not a single endpoint.
“Non-selective across MC1R–MC5R — a feature, not a flaw, for pathway research.”
What Makes Melanotan 2 Notable?
MT-2 is a cyclic heptapeptide engineered for greater stability than the linear α-MSH it derives from. The cyclisation is what buys it resistance to rapid breakdown, making it usable in longer study designs where native α-MSH would degrade.
Mechanism Breakdown
| Receptor | Research context | Engaged |
|---|---|---|
| MC1R | Pigmentation-pathway / melanocyte studies | ✓ |
| MC3R / MC4R | Energy-balance & appetite-signaling research | ✓ |
| MC5R | Exocrine / peripheral pathway studies | ✓ |
