Ampelopsin H has antioxidant activity, it shows that activity as radical hydroxyl scavenger an IC 50 4840.0 ug/mL.
(-)-Anonaine has some anticancer activity, it induces apoptosis through Bax- and caspase-dependent pathways in human cervical cancer (HeLa) cells, it induces DNA damage and inhibits growth and migration of human lung carcinoma h1299 cells. (-)-Anonaine may be considered a potent compound for chemotherapy against cervical cancer or a health food supplement for cancer chemoprevention. (-)-Anonaine has vasorelaxant effect.
Asarinin, a mammalian lignan precursor, has immunosuppression activity in vitro. Asarinin can decrease peripheral blood concentration of interleukin (IL)-12 and inhibit the expression of Toll-like receptor 4 (TLR4) and chemokine (C-X-C motif) receptor 3 (CXCR3), which means asarinin may have a role on TLR4 pathway and produced prolongation of allograft heart survival.
Bilobalide possesses anticonvulsant, insecticidal, and cardioprotective effects. Bilobalide exerts protective and trophic effects on neurons, the PI3K/Akt pathway may be involved in the protective effects of bilobalide; it also can protect PC12 cells from A beta 25-35-induced cytotoxicity, it dose-dependently attenuates the cytotoxic effect of A beta 25-35.
(-)-Catechin gallate is a minor constituent in green tea catechins, it inhibits the activity of COX-1 and COX-2 enzymes. Catechin gallate (IC50=53 microM) shows cytotoxicity against the colorectal adenocarcinoma cell line HCT116, it also exhibits strong anti-proliferative and anti-inflammatory activities on pancreatic ductal adenocarcinoma (PDAC) cells. Catechin 3-gallate is a good inhibitor of maltase, with IC50 values of 62 uM, it inhibits both α-glucosidases and rabbit glycogen phosphorylase (GP) in vitro and in cell culture, would contribute to the protection or improvement of type 2 diabetes.
Dihydroquercetin-rich extract (Lavitol) derived from the Dahurian larch tree, used as a food additive and as a dietary supplement ingredient.(+)-Dihydroquercetin has antioxidant activity, exhibits neuroprotective actions against the oxidative injuries induced in cortical cell cultures.
(-)-Epiafzelechin exhibits significant anti-inflammatory activity on carrageenin-induced mouse paw edema, it exhibits a dose-dependent inhibition on the COX activity with an IC50 value of 15 microM, it exhibits about 3-fold weaker inhibitory potency on the enzyme activity than indomethacin as a positive control. (-)-Epicatechin shows zero and/or the lowest activities against pancreatic lipase (IC50 > 20 microM). Epiafzelechin has antioxidant properties.
(-)-Epiafzelechin 3-O-gallate has antioxidant activity.
(-)-Epicatechin gallate can effectively stimulates osteoblast differentiation, it has antioxidative effect against lipid peroxidation when phospholipid bilayers are exposed to aqueous oxygen radicals.
(-)-Epicatechin-3-(3''-O-methyl) gallate is a natural product from Acacia catechu (L.F.) Willd.
