Quercetin is a flavonoid with anticancer activity. It inhibits mitochondrial ATPase, phosphodiesterase, PI3-kinase activity (IC50 = 3.8 μM) and slightly PIP kinase activity. It has antiproliferative effects on cancer cell lines; reduces cancer cell growth via type II estrogen receptors and has been reported to arrest human leukemic T cells in late G1phase of the cell cycle.
It induces apoptosis in K562, Molt-4, Raji, A549 and MCAS tumor cell lines.
