Apigenin (520-36-5) is a plant flavonoid with antioxidant properties. It has been reported to have myriad effects on biochemical pathways including kinase inhibition (CK2, PKC, ERK)1-3, CYP2CP inhibition4, inhibition of cellular proliferation via G2/M cell cycle arrest3,5, reduction of HIF-1 and VEGF expression6, and inhibition of nitric oxide and PGE2 synthesis7.
