In this current study, the effects of GA on mushroom tyrosinase, tyrosinase inhibitory activity, and melanin content were assessed in B16 melanoma cells (B16 cells). It is important to recognise that the observed association between protection by GA and protection of GSH cannot in itself establish that an increase in intracellular GSH is responsible for the protective effects of gallic acid—it could equally infer that gallic acid or delphinidin offers direct antioxidant protection resulting in protection of GSH. In addition, numerous studies have reported that antioxidants possess antiviral activities. However, gallic acid itself also appears to have antioxidant, anticarcinogenic and antiangiogenic activity in vitro. Results indicated that GA effectively down-regulated the RS generation and enhanced the GSH/GSSG ratio.
