Melanotan II

MT-II · Melano Glow · Cyclic alpha-MSH analogue

A modified version of a natural hormone that signals pigment-producing cells. It acts on several melanocortin receptors rather than just one.

MECHANISM OF ACTION

Melanotan II is a modified version of a natural hormone (alpha-MSH) that your skin normally uses to produce melanin (the pigment that makes skin darker). By directly activating the melanin-production switch, it triggers tanning without sunlight. But it doesn't stop there, it also activates other receptors (the same family of switches) that are found in the brain. One of these controls sexual arousal and appetite. This is the same receptor that the related molecule Bremelanotide (PT-141) acts on - PT-141 was developed out of Melanotan II research. Because it activates multiple receptor types non-selectively, it also comes with a stronger side effect profile (nausea, flushing, spontaneous erections) compared to more targeted compounds.

RESEARCH APPLICATIONS

  • Melanogenesis pathway research
  • MC1R/MC3R/MC4R receptor selectivity studies
  • Comparative melanocortin pharmacology

RESEARCH HIGHLIGHTS

Non-selective receptor activity

1996

Research characterises it as acting across several melanocortin receptor subtypes, which is the reason more selective analogues were later developed from it. Research observations only.
