4-Nitrobenzene-1,2-diol （4-Nitrocatechol） is a benzene derivative that is biologically active as an inhibitor of various enzymes.

2,6-Dibromophenol (2,6-Dibromo-phenol) is extracted from the skin and muscle of flatfish.

Anticanceragent 180 (compound 4) is a secondary metabolite found in fungal strains, extracted through physical interaction with streptomycetes. It possesses potential antitumor activity and can inhibit the migration of MDA-MB-231 breast cancer cells.

Pneumocandin A3 is a lipopeptide antibiotic with potent antifungal activity against Candida species, exhibiting inhibitory effects on 1,3-beta-D-glucan synthesis in vitro, with an IC50 range of 0.07-0.5 μg/mL.

6-Shogaol, an active constituent of ginger, is a potent inhibitor of MDA-MB-231 cell invasion, and the molecular mechanism involves at least in part the down-regulation of MMP-9 transcription by targeting the NF-κB activation cascade, thus has potential for clinical use as antimetastatic treatments.

Punicalin exerts anti-inflammatory, antioxidative, and anti-hepatotoxic activities, it shows inhibitory activity on HIV-1 reverse transcriptase in a dose-dependent manner, with an IC50 of 0.11 microg/ml (0.14 microM).

10-Shogaol, as an antioxidant for human skin cell growth and a migration enhancer with potential to be a novel wound repair agent.8- and 10-Shogaol have similar metabolic profiles to -shogaol and exhibit similar toxicity toward human colon cancer cells.

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.

Hericene A (Hericium erinaceus A) is a natural product that inhibits viability of HCT116 cells and can be used in biochemical experiments and drug synthesis.

Orcinol glucoside(Sakakin) shows potent antioxidative and anxiolytic activities without sedative effects, it can improve depressive behaviour in chronic unpredictable mild stress (CUMS) rats by downregulating HPA axis hyperactivity and increasing BDNF expression and ERK1/2 phosphorylation in the hippocampus.

Punicalagin has antifungal , antiviral, anti-atherosclerotic, hepatoprotective , anti-obesity., antiproliferative, anti-apoptotic, anti-inflammatory, and antioxidant effects. It can suppress the phosphorylation of MAPK including p38, c-JNK, and ERK, it also has potently inhibiting the activity of fatty acid synthase with half-inhibitory concentration values (IC 50 ) of 4.50μM.

Gastrodin has anti-inflammatory activity, can significantly attenuate levels of neurotoxic proinflammatory mediators and proinflammatory cytokines by inhibition of the NF-κB signaling pathway and phosphorylation of MAPKs in LPS-stimulated microglial cells, suggests that gastrodin has a potential as an anti-inflammatory drug candidate in neurodegenerative diseases.

Chebulic acid has effects against the progression of AGE-induced endothelial cell dysfunction, may constitute a promising intervention agent against diabetic vascular complications; it at both doses (25 and 50 mg/kg) improves biochemical alterations caused by renal ischemia in diabetic rats. Chebulic acid significantly reduced the tert-butyl hydroperoxide (t-BHP)-induced cell cytotoxicity, intracellular reactive oxygen species level, and the ratio of GSSH, oxidized form of glutathione (GSH) to the over total GSH (GSH + GSSG) (4.42%) as compared to that with t-BHP alone (8.33%).

Demethoxycurcumin (DMC) is one of the main active compounds of curcuminoids found in turmeric powder, which is used as a spice in Asian cooking and traditional medicine, has anti-inflammation and anti-cancer activities, the mechanism of DMC-mediated anti-invasive activity involves modulation of the expression of invasion-associated proteins, possibly by targeting NF-κB in MDA-MB-231 cells.

Corilagin has antitumour, anti-inflammatory, antioxidant, antifibrotics, antiviral, antibacterial, hepatoprotective, antiatherogenic, and antihypertensive activities. Corilagin reduces the cytotoxicity induced by EV71 or CA16 on Vero cells with and IC50 value of 5.6 and 32.33 μg/mL, respectively; it shows the potential to protect against HSV-1-induced encephalitis, and the beneficial effects may be mediated by inhibiting TLR2 signaling pathways. Corilagin attenuates bleomycin-induced epithelial injury and fibrosis via inactivation of oxidative stress, proinflammatory cytokine release and NF-κB and TGF-β1 signaling; it suppresses the activity of beta-lactamase to some extent.

Agarotetrol is a chromone derivative isolated from Agarwood.

Kavain has anticonvulsive properties, attenuating vascular smooth muscle contraction through interactions with voltage-dependent Na+ and Ca2+ channels. Kawain is advanced glycation endproduct inhibitors, can increase the mean life span of Caenorhabditis elegans exposed to high glucose.
