Brilliant Black BN

Brilliant black BN is a sulfonated azo dye with antiviral activity. It reduces the infectivity of enterovirus 71 (EV71) in rhabdomyosarcoma cells (IC50 = 10.1 µM) via inhibition of viral entry. Formulations containing brilliant black BN have commonly been used as food color additives.Formal Name: 4-(acetylamino)-5-hydroxy-6-[2-[7-sulfo-4-[2-(4-sulfophenyl)diazenyl]-1-naphthalenyl]diazenyl]-1,7-naphthalenedisulfonic acid, tetrasodium salt.
