生物活性

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
