Odor: characteristic Use: Flavokawain B, the hepatotoxic constituent from kava root, induces GSH-sensitive oxidative stress through modulation of IKK/NF-?B and MAPK signaling pathways.
Flavokawain B acts through ROS generation and GADD153 up-regulation to regulate the expression of Bcl-2 family members, thereby inducing mitochondrial dysfunction and apoptosis in HCT116 cells.
A potent anti-inflammatory. Flavokawain B significantly inhibited production of NO and PGE2 in LPS-induced RAW 264.7 cells.
Robust mechanisms for Flavokawain B induction of apoptosis preferentially for hormone-refractory prostate cancer and the potential usefulness of FKB for prevention and treatment of hormone-refractory prostate cancer in an adjuvant setting. |
