Flavokawain B

Flavokawain B (Flavokavain B) is an orally active chalcone. Flavokawain B results in activation of caspase-9, -3 and -8, cleavage of PARP. Flavokawain B down-regulates Bcl-2 with concomitant increase in Bax level. Flavokawain B inhibits NF-κB, PI3K/Akt and MAPK signaling pathway. Flavokawain B exhibits Apoptotic effects. Flavokawain B inhibits MMP-9 and promotes ROS generation. Flavokawain B inhibits multiple tumors and inflammation[1][2][3][4][5][6][7][8][9][10][11][12][13].
