Sodium copper chlorophyllin B exerts antiviral activities against Influenza virus and HIV with IC₅₀s of 50 to 100 μM for both of them. IC50 & Target: IC50: 50 to 100 μM (Influenza virus), 50 to 100 μM (HIV)^[1] In Vitro: Sodium copper chlorophyllin B exhibits influenza virus adsorption at 200 µM (P<0.05). The IC₅₀ and the 50% cytotoxic concentration (CC₅₀) of Sodium copper chlorophyllin lay from 50 to 100 µM and 200 to 400 µM, respectively. Sodium copper chlorophyllin B also inhibits HIV adsorption at 2.5 mM (P<0.05). The IC₅₀ and CC₅₀ of Sodium copper chlorophyllin lay from 50 to 100 µM and 200 to 400 µM, respectively^[1].
