Biochem Physiol Actions: A plant flavonoid that has been found to inhibit cell proliferation by arresting the cell cycle at the G2/M phase. Inhibition of growth through cell cycle arrest and induction of apoptosis appear to be related to induction of p53. Inhibits PMA-mediated tumor promotion by inhibiting protein kinase C and the resulting suppression of oncogene expression. It has also been reported to inhibit topoisomerase I-catalyzed DNA re-ligation and enhance gap junctional intercellular communication.
