Melanotan 1 Peptide Research Summary
n
Melanotan I (afamelanotide, NDP-alpha-MSH) is a synthetic linear analog of alpha-melanocyte stimulating hormone containing norleucine substitution at position 4 and D-phenylalanine substitution at position 7. It demonstrates preferential selectivity for the MC1R melanocortin receptor compared to the non-selective profile of Melanotan II.
n
Mechanism of Action Research
n
MT-I acts primarily through the MC1R receptor expressed on melanocytes. Receptor activation triggers adenylyl cyclase signaling, elevating intracellular cAMP, which activates protein kinase A (PKA) and the MITF pathway, leading to upregulation of tyrosinase and other enzymes involved in melanin biosynthesis in cell culture models.
n
All findings are from preclinical research. No therapeutic claims are made.
