Nonapeptide-1 (melanostatin-5) is a peptide hormone and a selective antagonist of MC1R (Ki: 40nM). Nonapeptide-1 is a competitive α-MSH antagonist that can effectively inhibit α-MSH-induced intracellular cAMP and melanosome dispersion in melanocytes (IC50 is 2.5nM and 11nM, respectively). Nonapeptide-1 inhibits melanin synthesis and can be used to study skin pigmentation, regulation of adrenal steroidogenesis, and skin cancer.
