Melanotan 1 (MT-1) is a synthetic peptide that shares similarities with the natural alpha-melanocyte-stimulating hormone (alpha-MSH). Initially developed as a sunless tanning agent, MT-1 has shown a range of effects beyond skin pigmentation, including sexual arousal, appetite regulation, and metabolic changes. This article delves into the various research findings on MT-1, exploring its potential applications in medicine and its mechanisms of action.

Melanotan 1 and Skin Pigmentation

  • Similarity to Alpha-MSH: MT-1 is closely related to alpha-MSH, differing by only one amino acid.
  • Receptor Binding: Both MT-1 and alpha-MSH bind to melanocortin receptors, particularly MC1, which is responsible for skin and hair pigmentation.
  • Tanning Effects: Clinical trials have shown that MT-1 increases the likelihood of tanning and reduces the risk of sunburn.

Beyond Skin Pigmentation: Additional Effects

  • Sexual Arousal: MT-1 has been found to increase sexual arousal.
  • Appetite and Metabolism: The peptide also affects appetite and basic metabolic rates.


  • Vitiligo Treatment: MT-1, in combination with UVB light therapy, has shown promise in treating vitiligo.
  • Actinic Keratosis: Research is underway to explore MT-1's potential in treating precancerous skin lesions.
  • High Blood Pressure: In hypertensive mice, MT-1 has shown protective effects against high blood pressure.

Neuroprotective Effects

  • Alzheimer's Disease: Studies in mice suggest that MT-1 could protect against cognitive decline and Alzheimer's disease.
  • Multiple Sclerosis: MT-1 has been found to prevent myelin loss in neurons, offering potential benefits in treating multiple sclerosis.

Mechanisms of Action

  • MC4 Receptor: MT-1's effects on T cells and inflammation are mediated through the MC4 receptor.
  • MC5 Receptor: The peptide also acts on the MC5 receptor, affecting fat storage and oxidation.


Melanotan 1 is a multifaceted peptide with a range of potential therapeutic applications. While initially developed for skin tanning, its effects on various physiological pathways make it a subject of ongoing research.
