Investigating anti-cancer properties of plant flavonoids and their derivatives

Currently, we are investigating the capacity and molecular mechanisms of specific flavonoids in the prevention of carcinogen-induced DNA damage in vitro and tumorigenesis using experimental animal models of certain cancers. Our research team is also interested in understanding the interaction between food bioactives and gut microbiome in relation to cancer prevention. Research in progress to develop cancer-preventive synbiotic functional food products. Furthermore, we synthesize and assess flavonoid derivatives for selective cytotoxicity on cancer cells for potential therapeutic applications to treat certain cancers.
