Review on Functions of Dietary Agents and Plants in Cancer Prevention and Treatment

Over 60% of the current anticancer drugs have their origin from natural sources. Natural products, dietary flavonoids and other polyphenols have an important role as chemo-preventive agents. These substances are compounds with different chemical entities and many of these are present in plants with medicinal value and in various fruits and vegetables commonly consumed by humans. The essential role played by natural products and dietary agents in the discovery and development of effective anticancer agents and the importance of multidisciplinary collaboration in the generation and optimization of novel molecular leads from natural product sources will be reviewed.
