Over eleven hundred publications reporting anticancer activities of polyphenols have appeared in the peerreviewed literature. In addition, a search of the PubMed database using “polyphenols ” cancer “ review” as keywords produced over 320 hits for review articles (July 2009). Polyphenol anticancer activities include, among others, anti-oxidative, pro-apoptotic, DNA damaging, anti-angiogenic, and immunostimulatory effects. Targeting specific protein kinases to combat cancer represents a major focus of oncology research within the so-called targeted therapy approach. An exhaustive search of the PubMed database (July 2009) using “polyphenols - cancer - kinases” as keywords resulted in more than 130 hits, half of them having been published within the past five years. Furthermore, the PubMed database contains 25 reviews on the subject of anti-kinase activity of some specific polyphenols, including mainly curcumin and the green tea polyphenol (-)-epigallocatechin 3-gallate (EGCG). However, no attempt has been made yet to review this area of research in a comprehensive, general manner. The current review therefore aims to highlight those anticancer polyphenols that target specific kinases in various types of cancer. The present review also provides an in-depth analysis of polyphenol structure- activity relationships in relation to their anticancer activities and specific kinase targeting. Lastly, a number of polyphenols are identified as potential antitumor agents that could be used to combat biologically aggressive cancers, including metastasizing cancers, through the targeting of specific kinases., Natural, Polyphenols, that, Display, Anticancer, Properties, through, Inhibition, of, Kinase, Activity
