CAS Number: 158563-45-2 Molecular formula:C61H87N15O9S Molar mass: 1206.5g/mol Medical use: Nonapeptide-1 is a biomimetic peptide that has a strong affinity for the MC1 receptor on melanocytes. As a result, it can act as an antagonist to melanocortin, competitively binding to the MC1 receptor and preventing the further activation of tyrosinase, thus inhibiting melanin production.
