Gomisin J
Catalog No: CFN90124

Gomisin J is a good substrate of cytochrome P450 3A4(CYP3A4), it has vasodilatory, anti-inflammatory, anti-diabetes, anti-oxidant, and anti-cancer effects, it also has preventive effects on angiotensin II-induced hypertension via an increased nitric oxide bioavailability. Gomisin J has potential benefits in treating nonalcoholic fatty liver disease, it can suppress lipid accumulation by regulating the expression of lipogenic and lipolytic enzymes and inflammatory molecule. Halogenated gomisin J is a potent inhibitor of the cytopathic effects of human immunodeficiency virus type 1 (HIV-1) on MT-4 human T cells (50% effective dose, 0.1 to 0.5 microM).

Gomisin N
Catalog No: CFN90125

Gomisin N has anti-oxdiant, anti-inflammatory, anti-cancer and anti-hepatitis activities; it produces beneficial sedative and hypnotic bioactivity, which may be mediated by the modification of the serotonergic and GABAergic system. Gomisin N can enhance TNF-α-induced apoptosis by suppressing of NF-κB and EGFR signaling pathways, and potentiate TRAIL-induced apoptosis through ROS-mediated up-regulation of death receptors 4 and 5.

epsilon-Viniferin
Catalog No: CFN97067

Epsilon-Viniferin is a bacteriostatic stilbenoid as it antagonized the bactericidal activity of vancomycin. Epsilon-viniferin shows a human cytochrome P450 enzymes inhition activity, it exhibits good antioxidant capacity in the DMSO/O(-)(2) polar system (IC50= 0.14 mM). Epsilon-viniferin and epsilon-viniferin pentaacetate slightly reduce cell proliferation but might protect from cell degenerescence.(-)-Trans-epsilon-viniferin is an inhibitor of noradrenaline and 5-hydroxytryptamine uptake and of monoamine oxidase activity, it may be of value as a structural template for the design and development of new antidepressant drugs.

alpha-Viniferin
Catalog No: CFN97068

Alpha-viniferin is a prostaglandin H2 synthase inhibitor, which has anti-inflammatory, anti-oxidant, anti-arthritis, and anti-tumor activities. Alpha-Viniferin inhibits AChE activity is specific, reversible and noncompetitive, in a dose-dependent manner, and the IC50 values of alpha-Viniferin were 2.0 microM. Alpha-Viniferin exhibits a dose-dependent inhibition on cyclooxygenase activity, where 50% of inhibition (IC50) was shown at a final concentration of about 7 microM, it down-regulates STAT-1-inducible inflammatory genes via inhibiting ERK-mediated STAT-1 activation in IFN-gamma-stimulated macrophages.

Vaccarin
Catalog No: CFN90131

Vaccarin exhibits extensive biological activities including vascular endothelial cell protective effects, it can significantly promote neovascularization by enhancing protein expression of p-Akt , p‑Erk, and CD31, and selectively protect vascular endothelium from dysfunction induced by H2O2.
