Demethyleneberberine, which is composed of a potential antioxidant structure, could penetrate the membrane of mitochondria and accumulate in mitochondria either in vitro or in vivo.Demethyleneberberine suppresses CYP2E1, hypoxia inducible factor α, and inducible nitric oxide synthase, which contributes to oxidative stress and restored sirtuin 1 AMP-activated protein kinase peroxisome proliferator-activated receptor-γ coactivator-1α pathway-associated fatty acid oxidation in chronic ethanol-fed mice.

Technical grade is a natural from Magnolia sieboldii

23-epi-26-Deoxyactein (27-Deoxyactein) has anti-inflammatory activity, it inhibits nitric oxide production by reducing iNOS expression without affecting activity of the enzyme. It also has anti-cancer activity, it can inhibit growth of the MCF7 human breast cancer cells and induce cell cycle arrest at G1.

Tubuloside A ( 8.6 microM) can inhibit D-galactosamine-induced death of hepatocytes. Tubuloside A has NO radical-scavenging activity, which possibly contributes to its anti-inflammatory effects.Tubuloside A shows stronger free radical scavenging activitie

α-Humulene (Alpha-caryophyllene) is extracted from S.officinalis essential oil.α-Humulene can inhibit tumor cell growth.α-Humulene also shows anti-inflammatory effects, probably by interfering with TNFalpha production and COX-2 and iNOS expression.

Eupatolide is isolated from the flowers of Inula japonica with anti-inflammatory activity. Eupatolide can be used in studies about TRAIL resistance in breast cancer cells.

1. Negletein (7-O-Methylbaicalein) has anti-inflammatory and immunomodulatory activities via inhibition of TNF-α, iNOS and IL-1β. 2. Negletein as a neuroprotectant enhances the action of nerve growth factor and induces neurite outgrowth in PC12 cells. 3. Negletein shows a comparable redox-active potential, and it (50 μM, 4 h) can activate Nrf2. 4. Negletein shows significant antimicrobial activity. 5. Negletein has anti-hypoxia activity, it can significantly prolong the survival time of hypoxic mice.6. Negletein has anti- Alzheimer's disease activity, it inhibits the iron-dependent formation of ROS and also blocks the iron-induced oligomerization of amyloid beta 42 in vitro. 7. Negletein (IC50: 3.89 + - 0.39 microM) exhibits potent inhibitory activity against nuclear factor of activated T cells (NFAT) transcription factor.

1. Ruscogenin has anti-inflammatory activity, suppressed zymosan A-evoked peritoneal total leukocyte migration in mice in a dose-dependent manner, 2. Ruscogenin inhibited adhesion of leukocytes to a human umbilical vein endothelial cell line (ECV34) injured by tumor necrosis factor-alpha (TNF-alpha) in a concentration-dependent manner. 3. Ruscogenin significantly attenuate LPS-induced acute lung injury via inhibiting expressions of TF and iNOS and NF-kappa B p65 activation.

AVE-9488 is a novel endothelial NO synthase (eNOS) enhancer that upregulates eNOS expression, induces NO production, and may ameliorate portal hypertension.
