Scientific Background
Melanotan I (afamelanotide) is a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH), a 14-amino-acid linear peptide that acts as a potent agonist at melanocortin receptors — particularly MC1R (melanocortin-1 receptor). Afamelanotide is the most clinically advanced melanocortin peptide and received EMA approval in 2014 under the brand name Scenesse for erythropoietic protoporphyria (EPP).
Unlike Melanotan II, Melanotan I is a linear peptide without the cyclic structure and does not significantly activate MC3R or MC4R, making it more selective for MC1R-mediated melanogenesis with minimal sexual side effects. MC1R activation by Melanotan I stimulates eumelanin (brown/black pigment) production in melanocytes through the cAMP/CREB signaling pathway, producing photoprotective tanning without requiring UV exposure — though UV exposure substantially accelerates the tanning response.
Beyond pigmentation, MC1R has roles in anti-inflammatory signaling, photoprotection from UV-induced DNA damage, and regulation of melanocyte proliferation. Research continues to explore Melanotan I's applications in photodermatology, vitiligo, and skin protection from solar radiation.

Regulatory Note: Melanotan I (afamelanotide) is the only melanocortin peptide with formal EMA approval (Scenesse, CLINUVEL Pharmaceuticals), licensed for erythropoietic protoporphyria. Research use of this compound draws on a substantial clinical evidence base distinguishing it from most investigational peptides. Unlike Melanotan II, it does not significantly activate MC4R and therefore lacks the sexual arousal and appetite-suppressive effects associated with MC4R agonism.
