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.

1. Desmethoxyyangonin (5,6-Dehydrokavain) protects LPS or LPS/D-GalN-induced damages in cell or liver tissues mainly through de-regulating IKK/NFκB and Jak2/STAT3 signaling pathways. 2. The induction of CYP3A23 by dihydromethysticin and Desmethoxy yangonin involves transcription activation, probably through a PXR-independent or PXR-involved indirect mechanism.

Piperlonguminine, an alkaloid amide isolated from the Piper species, exhibits anti-inflammatory, antitumor, neuroprotective, anti-platelet, anti-melanogenic, antifungal, and antibacterial activities. It inhibits Akt/mTOR signaling, promotes autophagy, and mediates cancer cell death.

Dihydromethysticin ((+)-Dihydromethysticin) is a kavalactone found in Piper methysticum. It has marked activity on the induction of CYP3A23.

NSC-37445 has anti-tumor activity, such as inhibits growth of bladder tumor cells in a nude mice model , prevents the recurrence and progression of non-muscle-invasive urothelial cell carcinoma. NSC-37445 can significantly reduce the expression of CDK1-inhibitory kinases, Myt1 and Wee1, and cause cyclin B1 protein accumulation leading to CDK1 activation in T24 cells. 3. Flavokawain A (Flavokavain A) may exert anti-inflammatory responses by suppressing LPS-induced expression of pro-inflammatory mediators via blockage of NF-κB-AP-1-JNK/p38 MAPK signaling pathways in the murine macrophages.

Dihydrokavain (Marindinin), a prominent kavalactone in the kava plant, significantly contributes to the plant's anxiolytic effects, as evidenced by a study conducted on chicks.
