Hot Natural Products & Bioactive Compounds

1. Damnacanthal possesses anti-cancer property, can treat or prevent hepatocellular carcinoma through its inhibitory effects on the HGF/c-Met axis.
2. Damnacanthal inhibits mast cell activation induced by different stimuli and open a new window for the use of this compound as a mast cell stabilizer.
3. P53-mediated Damnacanthal induces apoptosis through the activation of p21 and caspase-7.
4. Damnacanthal possesses anti-inflammatory property, can inhibit the NF-κB/receptor-interacting protein-2/caspase-1 signal pathway by inhibiting p56lck tyrosine kinase .
5. Damnacanthal and noni extract supplements containing it could be potentially interesting for the treatment and/or chemoprevention of hepatocellular carcinoma through its inhibitory effects on the HGF/c-Met axis.
6. Damnacanthal has antinociceptive and anti-inflammatory actions in mice.
7. Damnacanthal can act as an immunomodulatory agent which may be very useful for maintaining a healthy immune system.

Bergenin is a potent antinarcotic agent, has antiviral ,antifungal, antiarrhythmic, antitumor, antiinflammatory, potent immunomodulatory, antitussive, antiulcerogenic,anti-plasmodial, anti-hepatotoxic and wound healing activities. Bergenin has antidiabetic activity, could be classified as a new group of α-glucosidase inhibitors. Bergenin reduces the expression of NO, TNF-α, IL-1β, and IL-6 proinflammatory cytokines by inhibiting the activation of the NF-κB and MAPKs signaling pathways, and it may represent a novel treatment strategy for mastitis.

1. Neostenine shows significant antitussive activities.

Nobiletin, a citrus flavonoid isolated from citrus peels like in tangerine, which has anti-inflammatory and anti-tumor activities, it could be a potential protective agent for the prevention and treatment of restenosis after angioplasty. Nobiletin downregulated the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase 2 (COX-2), suppressed cell viability through AKT pathways.

Berbamine is a novel inhibitor of bcr/abl fusion gene with potent anti-leukemia activity and also an inhibitor of NF-κB. Berbamine may be the first ATP-competitive inhibitor of CaMKII γ, could be as a new type of molecular targeted agent through inhibition of the CaMKII γ activity for treatment of leukemia.Berbamine confers cardioprotection against I/R injury by attenuating [Ca(2+)inf(i) overloading and preventing calpain activation through the activation of the PI3K-Akt-GSK3β pathway and, subsequently, opening of the mitoK(ATP) channel.

1. Atranorin shows significant antinociceptive and antiinflammatory activity.
2. Atranorin has a relevant redox-active action, acting as a pro-oxidant or antioxidant agent depending on the radical, also, it will exert cytoprotective effects on cells under oxidative stress induced by H(2)O(2).
3. Atranorin has suppression of viability and proliferation in tumour cell lines.

Cotoin is a natural product from Garcinia virgata.

Canthin-6-one has antimicrobial, cytotoxic, antiproliferative and proapoptotic effects, possibly by interfering with the G2/M transition; it also has antiinflammatory activity by interfering with the transcription factors NF-κB and AP-1 at transcriptional level.
