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.

Piperlongumine (Piplartine) is a natural alkaloid from Piper longum L. It selectively kills cancer cells and strengthens the level of reactive oxygen species (ROS).

Methysticin is a kavalactone isolated from the kava roots. Methylsticin (Methysticin) exhibit osteoclast formation inhibitory activity. It inhibits activation of NF-χB in lung adenocarcinoma tissue, activates Nrf2 in neurons and astroglia, decreases peak amplitude of voltage-gated Na+ channels in hippocampal neurons, and suppresses growth of Fusarium, Trichoderma, and Colletotrichum.

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.

N-Nornuciferine hydrochloride(4846-19-9 free base) (N-Nornuciferine hydrochloride) is an aporphine alkaloid in lotus leaf, significantly inhibits CYP2D6 (IC50: 3.76 μM, Ki: 2.34 μM).

Piperlotine A is an alkaloid that can be extracted from Piperonyssinus rolfsii and has antiplatelet aggregation activity.Piperlotine A showed inhibition of Mycobacterium tuberculosis in an in vitro assay with a MIC value of 50 ug/mL.Piperlotine A is an alkaloid that can be extracted from Piperonyssinus rolfsii and has antiplatelet aggregation activity.

Yangonin (Y100550) is a novel CB receptor ligand, it exhibits affinity for the human recombinant CB receptor. Yangonin (Y100550) could be a valuable candidate for the intervention of NF-κB-dependent pathological conditions such as inflammation.

Piperine (Bioperine) , a alkaloid, has been used in trials studying the treatment of multiple myeloma and deglutition disorders.

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

Decanedioic acid (Sebacinsaure) is a saturated, straight-chain naturally occurring dicarboxylic acid.

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.

Tetrahydropiperine (Cosmoperine) is a natural product derived from piperine, can be used to treat convulsion, epilepsy, relieve pain, and control insects.

5,7-DIMETHOXYFLAVONE possessed remarkable leishmanicidal potential.

piperitone is a natural compound from Piper nigrum L

Valeramide is an amide compound isolated from the roots of Ottonia anisum Spreng.

3-(3,4,5-Trimethoxyphenyl)propanoic acid, a constituent of Piper retrofractum and Piper longum, is found in herbs and spices.

4-Allylcatechol (Hydroxychavicol) has antioxidant activity, it has protective activity against the photosensitization-induced damage to lipids and proteins of rat liver mitochondria, which attributes to its free radical and singlet oxygen scavenging properties.

Methyl (E)-4-hydroxycinnamatee is found in several plants such as onion or Morinda citrifolia. It induces apoptosis in combination with Carnosic Acid and kills acute myeloid leukemia cells. It has antioxidant and antibacterial activity.

p-Hydroxy-5,6-dehydrokawain (4'-Hydroxydehydrokawain) is isolated from Kawain.

1-Cinnamoylpyrrolidine, a natural product prepared from Piper caninum, can be used as a DNA strand breaking agent, inducing the relaxation of the plasmid pBR322 DNA superhelix in the presence of Cu2+. 1-Cinnamoylpyrrolidine inhibits PAF-induced platelet aggregation with an IC50 value of 37.3 μM. value was 37.3 μM.
