Research Data

What Is Melanotan I?

Melanotan I (afamelanotide) is a synthetic linear analog of alpha-melanocyte stimulating hormone (alpha-MSH). It activates MC1R receptors on melanocytes to stimulate eumelanin production, increasing skin pigmentation independent of UV radiation. It received EU approval (as Scenesse) for erythropoietic protoporphyria, providing clinical validation for MC1R-driven photoprotection.

Research Context

MC1R receptor activation and eumelanin synthesis in melanocytes
Photoprotection mechanism: melanin as UV radiation absorber
Comparison with Melanotan II for receptor selectivity (linear vs cyclic)
Erythropoietic protoporphyria research (EU-approved indication basis)
Melanogenesis pathway research in pigmentation biology
