Research Mechanism Summary

Melanotan-1 (afamelanotide) is a 13-amino-acid synthetic analogue of α-MSH incorporating two stabilizing substitutions: norleucine at position 4 and D-phenylalanine at position 7. These modifications confer approximately 1,000-fold greater potency at the melanocortin-1 receptor (MC1R) versus native α-MSH and extend its plasma half-life. MC1R activation initiates cAMP-dependent signaling in melanocytes, upregulating microphthalmia-associated transcription factor (MITF) and downstream eumelanin biosynthesis enzymes including tyrosinase—producing UV-protective melanin without requiring UV exposure in vitro (https://biolongevitylabs.com/product/melanotan-1-10mg/). In three Phase II/III clinical trials in erythropoietic protoporphyria (EPP) patients, afamelanotide-treated subjects tolerated approximately 64 hours of sunlight exposure vs. approximately 40 hours in placebo groups. Anti-inflammatory and antifibrotic effects through downregulation of TGF-β1, COX-2, and α-SMA are also under active preclinical investigation in liver fibrosis models (https://www.corepeptides.com/peptides/melanotan-1-10mg/).
