flavokawain b

1. Flavokawain B (Flavokavain B) has potent anti-inflammatory activity, can significantly inhibit production of NO and PGE2 in LPS-induced RAW 264.7 cells. 2. Flavokawain B, the hepatotoxic constituent from kava root, induces GSH-sensitive oxidative stress through modulation of IKK/NF-κB and MAPK signaling pathways. 3. Flavokawain B induces apoptosis, has the potential usefulness of FKB for prevention and treatment of hormone-refractory prostate cancer in an adjuvant setting. 4. 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.

Flavokawain 1i, a derivative of chalcones flavokawain A, flavokawain B, and flavokawain C, exhibits anticancer and antiviral properties. At a concentration of 30 µM, it suppresses the growth of gefitinib-resistant H1975 non-small cell lung cancer (NSCLC) cells by 36% and modulates the protein expression by reducing the levels of heat shock protein 90 (Hsp90) client proteins, including EGFR, c-Met, HER2, Akt, and cyclin-dependent kinase 4 (Cdk4), while increasing the levels of Hsp70, indicative of Hsp90 inhibition. Additionally, intramuscular injection of flavokawain 1i lowers viral loads in pigs afflicted with porcine reproductive and respiratory syndrome virus (PRRSV).
