Resveratrol
Resveratrol is a stilbenol that is stilbene in which the phenyl groups are substituted at positions 3, 5, and 4 by hydroxy groups. It has a role as a phytoalexin, an antioxidant, a glioma-associated oncogene inhibitor and a geroprotector. It is a stilbenol, a polyphenol and a member of resorcinols. Resveratrol (3,5,4-trihydroxystilbene) is a polyphenolic phytoalexin. It is a stilbenoid, a derivate of stilbene, and is produced in plants with the help of the enzyme stilbene synthase. It exists as cis-(Z) and trans-(E) isomers. The trans- form can undergo isomerisation to the cis- form when heated or exposed to ultraviolet irradiation. In a 2004 issue of Science, Dr. Sinclair of Harvard University said resveratrol is not an easy molecule to protect from oxidation. It has been claimed that it is readily degraded by exposure to light, heat, and oxygen. However, studies find that Trans-resveratrol undergoes negligible oxidation in normal atmosphere at room temperature. Resveratrol is a plant polyphenol found in high concentrations in red grapes that has been proposed as a treatment for hyperlipidemia and to prevent fatty liver, diabetes, atherosclerosis and aging. Resveratrol use has not been associated with serum enzyme elevations or with clinically apparent liver injury. Resveratrol is a natural product found in Vitis rotundifolia, Vitis amurensis, and other organisms with data available. Resveratrol is a phytoalexin derived from grapes and other food products with antioxidant and potential chemopreventive activities. Resveratrol induces phase II drug-metabolizing enzymes (anti-initiation activity); mediates anti-inflammatory effects and inhibits cyclooxygenase and hydroperoxidase functions (anti-promotion activity); and induces promyelocytic leukemia cell differentiation (anti-progression activity), thereby exhibiting activities in three major steps of carcinogenesis. This agent may inhibit TNF-induced activation of NF-kappaB in a dose- and time-dependent manner. (NCI05) Resveratrol is a metabolite found in or produced by Saccharomyces cerevisiae. A stilbene and non-flavonoid polyphenol produced by various plants including grapes and blueberries. It has anti-oxidant, anti-inflammatory, cardioprotective, anti-mutagenic, and anti-carcinogenic properties. It also inhibits platelet aggregation and the activity of several DNA HELICASES in vitro. Resveratrol is a polyphenolic phytoalexin. It is also classified as a stilbenoid, a derivate of stilbene, and is produced in plants with the help of the enzyme stilbene synthase. The levels of resveratrol found in food vary greatly. Red wine contains between 0.2 and 5.8 mg/L depending on the grape variety, while white wine has much less. The reason for this difference is that red wine is fermented with grape skins, allowing the wine to absorb the resveratrol, whereas white wine is fermented after the skin has been removed. Resveratrol is also sold as a nutritional supplement. A number of beneficial health effects, such as anti-cancer, antiviral, neuroprotective, anti-aging, anti-inflammatory, and life-prolonging effects have been reported for resveratrol. The fact that resveratrol is found in the skin of red grapes and as a constituent of red wine may explain the "French paradox". This paradox is based on the observation that the incidence of coronary heart disease is relatively low in southern France despite high dietary intake of saturated fats. Resveratrol is thought to achieve these cardioprotective effects by a number of different routes: (1) inhibition of vascular cell adhesion molecule expression; (2) inhibition of vascular smooth muscle cell proliferation; (3) stimulation of endothelial nitric oxide synthase (eNOS) activity; (4) inhibition of platelet aggregation; and (5) inhibition of LDL peroxidation (PMID: 17875315, 14676260, 9678525). Resveratrol is a biomarker for the consumption of grapes and raisins. A stilbenol that is stilbene in which the phenyl groups are substituted at positions 3, 5, and 4 by hydroxy groups.

delta7-Avenasterol
delta7-Avenasterol, also known as 7-dehydroavenasterol or 24Z-ethylidenelathosterol, belongs to the class of organic compounds known as stigmastanes and derivatives. These are sterol lipids with a structure based on the stigmastane skeleton, which consists of a cholestane moiety bearing an ethyl group at the carbon atom C24. Thus, delta7-avenasterol is considered to be a sterol lipid molecule. delta7-Avenasterol has been detected, but not quantified in, several different foods, such as garden onions, fenugreeks, vaccinium (blueberry, cranberry, huckleberry), grapefruit/pummelo hybrids, and pulses. This could make delta7-avenasterol a potential biomarker for the consumption of these foods. delta7-Avenasterol is an intermediate in the biosynthesis of steroids. It is the fourth to last step in the synthesis of stigmasterol and is converted from 24-ethylidenelophenol. It is then converted into 5-dehydroavenasterol via the enzyme lathosterol oxidase (EC 1.14.21.6). Avenasterol, also known as (24z)-5alpha-stigmasta-7,24(28)-dien-3beta-ol or 7-dehydroavenasterol, belongs to stigmastanes and derivatives class of compounds. Those are sterol lipids with a structure based on the stigmastane skeleton, which consists of a cholestane moiety bearing an ethyl group at the carbon atom C24. Thus, avenasterol is considered to be a sterol lipid molecule. Avenasterol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Avenasterol can be found in a number of food items such as rice, black chokeberry, dandelion, and common mushroom, which makes avenasterol a potential biomarker for the consumption of these food products.

CA 4P
Fosbretabulin Disodium is the disodium salt of a water-soluble phosphate derivative of a natural stilbenoid phenol derived from the African bush willow (Combretum caffrum) with potential vascular disrupting and antineoplastic activities. Upon administration, the prodrug fosbretabulin is dephosphorylated to its active metabolite, the microtubule-depolymerizing agent combretastatin A4, which binds to tubulin dimers and prevents microtubule polymerization, resulting in mitotic arrest and apoptosis in endothelial cells. In addition, this agent disrupts the engagement of the endothelial cell-specific junctional molecule vascular endothelial-cadherin (VE-cadherin) and so the activity of the VE-cadherin/beta-catenin/Akt signaling pathway, which may result in the inhibition of endothelial cell migration and capillary tube formation. As a result of fosbretabulins dual mechanism of action, the tumor vasculature collapses, resulting in reduced tumor blood flow and ischemic necrosis of tumor tissue. Fosbretabulin disodium (CA 4DP) is a tubulin destabilizing agent. Fosbretabulin disodium is the Combretastatin A4 proagent that selectively targets endothelial cells, induces regression of nascent tumour neovessels, reduces tumour blood flow and causes central tumour necrosis[1][3].

(E)-3,5,4-Trimethoxystilbene
(E)-3,5,4-Trimethoxystilbene is a natural product found in Dalea versicolor, Streptomyces avermitilis, and other organisms with data available. Trans-Trimethoxyresveratrol is a derivative of Resveratrol (RSV),and it may be a more potent anti-inflammatory, antiangiogenic and vascular-disrupting agent when compared with resveratrol. In vitro: The in vitro study of resveratrol and trans-Trimethoxyresveratrol showed rather weak cytotoxic effects on three cancer cell lines (HepG2, MCF-7, and MDA-MB-231), which contradicted a previous study reporting that resveratrol inhibited MCF-7 cells with an IC50 of about 10 μM. This discrepancy might be explained by the fact that the measurements were made 24 h after drug treatment, whereas the measurements of the previous study were taken 6 days after. The fact that the cytotoxic effect of trans-Trimethoxyresveratrol was lower than that of resveratrol is surprising, because in many studies, trans-Trimethoxyresveratrol is the most active analogue of resveratrol , although resveratrol shows much stronger antioxidant effects than that of trans-Trimethoxyresveratrol.[1] In vivo: Zebrafish embryos offer great advantage over their adults as well as other in vivo models because of the external development and optical transparency during their first few days, making them invaluable in the inspection of developmental processes. These unique advantages can even be made more useful when specific cell types are labeled with fluorescent probes. Zebrafish embryo in vivo, suggests that trans-Trimethoxyresveratrol has both more potent antiangiogenic activity and more importantly, stronger specific cytotoxic effects on endothelial cells than does resveratrol.[1] Trans-Trimethoxyresveratrol is a derivative of Resveratrol (RSV),and it may be a more potent anti-inflammatory, antiangiogenic and vascular-disrupting agent when compared with resveratrol.

Oxypalmatine
8-Oxypalmatine is a natural product found in Berberis actinacantha, Limaciopsis loangensis, and other organisms with data available. Oxypalmatine is isolated from Phellodendron amurense[1].
Triacetylresveratrol
Triacetylresveratrol, an acetylated analog of Resveratrol. Triacetylresveratrol decreases the phosphorylation of STAT3 and NF-κB in a dose- and time- dependent manner in PANC-1 and BxPC-3 cells. Anticancer effects[1]. Triacetylresveratrol, an acetylated analog of Resveratrol.
