Luteolin

4H-1-Benzopyran-4-one, 2-(3,4-dihydroxyphenyl)-5,7-dihydroxy-

C15H10O6 (286.047736)


Luteolin is a naturally occurring flavonoid. (PMID:17168665). The flavonoids are polyphenolic compounds found as integral components of the human diet. They are universally present as constituents of flowering plants, particularly of food plants. The flavonoids are phenyl substituted chromones (benzopyran derivatives) consisting of a 15-carbon basic skeleton (C6-C3-C6), composed of a chroman (C6-C3) nucleus (the benzo ring A and the heterocyclic ring C), also shared by the tocopherols, with a phenyl (the aromatic ring B) substitution usually at the 2-position. Different substitutions can typically occur in the rings, A and B. Several plants and spices containing flavonoid derivatives have found application as disease preventive and therapeutic agents in traditional medicine in Asia for thousands of years. The selection of a particular food plant, plant tissue or herb for its potential health benefits appears to mirror its flavonoid composition. The much lower risk of colon, prostate and breast cancers in Asians, who consume more vegetables, fruits and tea than populations in the Western hemisphere do, raises the question of whether flavonoid components mediate the protective effects of diets rich in these foodstuffs by acting as natural chemopreventive and anticancer agents. An impressive body of information exists on the antitumoral action of plant flavonoids. In vitro work has concentrated on the direct and indirect actions of flavonoids on tumor cells, and has found a variety of anticancer effects such as cell growth and kinase activity inhibition, apoptosis induction, suppression of the secretion of matrix metalloproteinases and of tumor invasive behavior. Furthermore, some studies have reported the impairment of in vivo angiogenesis by dietary flavonoids. Experimental animal studies indicate that certain dietary flavonoids possess antitumoral activity. The hydroxylation pattern of the B ring of the flavones and flavonols, such as luteolin seems to critically influence their activities, especially the inhibition of protein kinase activity and antiproliferation. The different mechanisms underlying the potential anticancer action of plant flavonoids await further elucidation. Certain dietary flavonols and flavones targeting cell surface signal transduction enzymes, such as protein tyrosine and focal adhesion kinases, and the processes of angiogenesis appear to be promising candidates as anticancer agents. Further in vivo studies of these bioactive constituents is deemed necessary in order to develop flavonoid-based anticancer strategies. In view of the increasing interest in the association between dietary flavonoids and cancer initiation and progression, this important field is likely to witness expanded effort and to attract and stimulate further vigorous investigations (PMID:16097445). Luteolin is a tetrahydroxyflavone in which the four hydroxy groups are located at positions 3, 4, 5 and 7. It is thought to play an important role in the human body as an antioxidant, a free radical scavenger, an anti-inflammatory agent and an immune system modulator as well as being active against several cancers. It has a role as an EC 2.3.1.85 (fatty acid synthase) inhibitor, an antineoplastic agent, a vascular endothelial growth factor receptor antagonist, a plant metabolite, a nephroprotective agent, an angiogenesis inhibitor, a c-Jun N-terminal kinase inhibitor, an anti-inflammatory agent, an apoptosis inducer, a radical scavenger and an immunomodulator. It is a 3-hydroxyflavonoid and a tetrahydroxyflavone. It is a conjugate acid of a luteolin-7-olate. Luteolin is a natural product found in Verbascum lychnitis, Carex fraseriana, and other organisms with data available. Luteolin is a naturally-occurring flavonoid, with potential anti-oxidant, anti-inflammatory, apoptosis-inducing and chemopreventive activities.

Genistein

Genistein, Pharmaceutical Secondary Standard; Certified Reference Material

C15H10O5 (270.052821)


Genistein is a 7-hydroxyisoflavone with additional hydroxy groups at positions 5 and 4. It is a phytoestrogenic isoflavone with antioxidant properties. It has a role as an antineoplastic agent, a tyrosine kinase inhibitor, an EC 5.99.1.3 [DNA topoisomerase (ATP-hydrolysing)] inhibitor, a phytoestrogen, a plant metabolite, a geroprotector and a human urinary metabolite. It is a conjugate acid of a genistein(1-). An isoflavonoid derived from soy products. It inhibits protein-tyrosine kinase and topoisomerase-II (DNA topoisomerases, type II) activity and is used as an antineoplastic and antitumor agent. Experimentally, it has been shown to induce G2 phase arrest in human and murine cell lines. Additionally, genistein has antihelmintic activity. It has been determined to be the active ingredient in Felmingia vestita, which is a plant traditionally used against worms. It has shown to be effective in the treatment of common liver fluke, pork trematode and poultry cestode. Further, genistein is a phytoestrogen which has selective estrogen receptor modulator properties. It has been investigated in clinical trials as an alternative to classical hormone therapy to help prevent cardiovascular disease in postmenopausal women. Natural sources of genistein include tofu, fava beans, soybeans, kudzu, and lupin. Genistein is a natural product found in Pterocarpus indicus, Ficus septica, and other organisms with data available. Genistein is a soy-derived isoflavone and phytoestrogen with antineoplastic activity. Genistein binds to and inhibits protein-tyrosine kinase, thereby disrupting signal transduction and inducing cell differentiation. This agent also inhibits topoisomerase-II, leading to DNA fragmentation and apoptosis, and induces G2/M cell cycle arrest. Genistein exhibits antioxidant, antiangiogenic, and immunosuppressive activities. (NCI04) Genistein is one of several known isoflavones. Isoflavones compounds, such as genistein and daidzein, are found in a number of plants, but soybeans and soy products like tofu and textured vegetable protein are the primary food source. Genistein is a natural bioactive compound derived from legumes and has drawn because of its potentially beneficial effects on some human degenerative diseases. It has a weak estrogenic effect and is a well-known non-specific tyrosine kinase inhibitor at pharmacological doses. Epidemiological studies show that genistein intake is inversely associated with the risk of cardiovascular diseases. Data suggests a protective role of genistein in cardiovascular events. However, the mechanisms of the genistein action on vascular protective effects are unclear. Past extensive studies exploring its hypolipidemic effect resulted in contradictory data. Genistein also is a relatively poor antioxidant. However, genistein protects against pro-inflammatory factor-induced vascular endothelial barrier dysfunction and inhibits leukocyte-endothelium interaction, thereby modulating vascular inflammation, a major event in the pathogenesis of atherosclerosis. Genistein exerts a non-genomic action by targeting on important signaling molecules in vascular endothelial cells (ECs). Genistein rapidly activates endothelial nitric oxide synthase and production of nitric oxide in ECs. This genistein effect is novel since it is independent of its known effects, but mediated by the cyclic adenosine monophosphate/protein kinase A (cAMP/PKA) cascade. Genistein directly stimulates the plasma membrane-associated adenylate cyclases, leading to activation of the cAMP signaling pathway. In addition, genistein activates peroxisome proliferator-activated receptors, ligand-activated nuclear receptors important to normal vascular function. Furthermore, genistein reduces reactive oxygen species (ROS) by attenuating the expression of ROS-producing enzymes. These findings reveal the roles for genistein in the regulation of vascular function and provide a basis for further investigating its therapeutic potential f...

(PMID:17979711). Genistein is a biomarker for the consumption of soy beans and other soy products. Genistein is a phenolic compound belonging to the isoflavonoid group. Isoflavonoids are found mainly in soybean. Genistein and daidzein (an other isoflavonoid) represent the major phytochemicals found in this plant. Health benefits (e.g. reduced risk for certain cancers and diseases of old age) associated to soya products consumption have been observed in East Asian populations and several epidemiological studies. This association has been linked to the action of isoflavonoids. With a chemical structure similar to the hormone 17-b-estradiol, soy isoflavones are able to interact with the estrogen receptor. They also possess numerous biological activities. (PMID: 15540649). Genistein is a biomarker for the consumption of soy beans and other soy products.

Hypericin is found in alcoholic beverages. Hypericin is widespread in Hypericum species especially Hypericum perforatum (St Johns Wort) Hypericin is a red-coloured anthraquinone-derivative, which, together with hyperforin, is one of the principal active constituents of Hypericum (Saint Johns wort). Hypericin is believed to act as an antibiotic and non-specific kinase inhibitor. Hypericin may inhibit the action of the enzyme dopamine -hydroxylase, leading to increased dopamine levels, although thus possibly decreasing norepinephrine and epinephrine D002491 - Central Nervous System Agents > D011619 - Psychotropic Drugs > D000928 - Antidepressive Agents Widespread in Hypericum subspecies especies Hypericum perforatum (St Johns Wort) D007155 - Immunologic Factors > D007166 - Immunosuppressive Agents C274 - Antineoplastic Agent > C1931 - Antineoplastic Plant Product D000890 - Anti-Infective Agents > D000998 - Antiviral Agents D011838 - Radiation-Sensitizing Agents D000970 - Antineoplastic Agents C1907 - Drug, Natural Product D004791 - Enzyme Inhibitors Hypericin is a carbopolycyclic compound. It has a role as an antidepressant. It derives from a hydride of a bisanthene. Hypericin is a natural product found in Hypericum adenotrichum, Hypericum bithynicum, and other organisms with data available. Hypericin is an anthraquinone derivative that is naturally found in the yellow flower of Hypericum perforatum (St. Johns wort) with antidepressant, potential antiviral, antineoplastic and immunostimulating activities. Hypericin appears to inhibit the neuronal uptake of serotonin, norepinephrine, dopamine, gamma-amino butyric acid (GABA) and L-glutamate, which may contribute to its antidepressant effect. Hypericin may also prevent the replication of encapsulated viruses probably due to inhibition of the assembly and shedding of virus particles in infected cells. This agent also exerts potent phototoxic effects by triggering apoptotic signaling that results in formation of reactive oxygen species. Hypericin is a naturally occurring substance found in Hyperlcurn perforatum L. Hypericin is an inhibitor of PKC (protein kinase C), MAO (monoaminoxidase), dopamine-beta-hydroxylase, reverse transcriptase, telomerase and CYP (cytochrome P450). Hypericin shows antitumor, antiviral, antidepressive activities, and can induce apoptosis[1][2][3]. Hypericin is a naturally occurring substance found in Hyperlcurn perforatum L.

Quercetin

4H-1-Benzopyran-4-one,2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxy-, zirconium(2+) salt (1:1)

C15H10O7 (302.042651)


Quercetin appears as yellow needles or yellow powder. Converts to anhydrous form at 203-207 °F. Alcoholic solutions taste very bitter. (NTP, 1992) Quercetin is a pentahydroxyflavone having the five hydroxy groups placed at the 3-, 3-, 4-, 5- and 7-positions. It is one of the most abundant flavonoids in edible vegetables, fruit and wine. It has a role as an antibacterial agent, an antioxidant, a protein kinase inhibitor, an antineoplastic agent, an EC 1.10.99.2 [ribosyldihydronicotinamide dehydrogenase (quinone)] inhibitor, a plant metabolite, a phytoestrogen, a radical scavenger, a chelator, an Aurora kinase inhibitor and a geroprotector. It is a pentahydroxyflavone and a 7-hydroxyflavonol. It is a conjugate acid of a quercetin-7-olate. Quercetin is a flavonol widely distributed in plants. It is an antioxidant, like many other phenolic heterocyclic compounds. Glycosylated forms include RUTIN and quercetrin. Quercetin is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Quercetin is a flavonoid found in many foods and herbs and is a regular component of a normal diet. Extracts of quercetin have been used to treat or prevent diverse conditions including cardiovascular disease, hypercholesterolemia, rheumatic diseases, infections and cancer but have not been shown to be effective in clinical trials for any medical condition. Quercetin as a nutritional supplement is well tolerated and has not been linked to serum enzyme elevations or to episodes of clinically apparent liver injury. Quercetin is a natural product found in Lotus ucrainicus, Visnea mocanera, and other organisms with data available. Quercetin is a polyphenolic flavonoid with potential chemopreventive activity. Quercetin, ubiquitous in plant food sources and a major bioflavonoid in the human diet, may produce antiproliferative effects resulting from the modulation of either EGFR or estrogen-receptor mediated signal transduction pathways. Although the mechanism of action of action is not fully known, the following effects have been described with this agent in vitro: decreased expression of mutant p53 protein and p21-ras oncogene, induction of cell cycle arrest at the G1 phase and inhibition of heat shock protein synthesis. This compound also demonstrates synergy and reversal of the multidrug resistance phenotype, when combined with chemotherapeutic drugs, in vitro. Quercetin also produces anti-inflammatory and anti-allergy effects mediated through the inhibition of the lipoxygenase and cyclooxygenase pathways, thereby preventing the production of pro-inflammatory mediators. Quercetin is a flavonoid widely distributed in many plants and fruits including red grapes, citrus fruit, tomato, broccoli and other leafy green vegetables, and a number of berries, including raspberries and cranberries. Quercetin itself (aglycone quercetin), as opposed to quercetin glycosides, is not a normal dietary component. Quercitin glycosides are converted to phenolic acids as they pass through the gastrointestinal tract. Quercetin has neither been confirmed scientifically as a specific therapeutic for any condition nor been approved by any regulatory agency. The U.S. Food and Drug Administration has not approved any health claims for quercetin. Nevertheless, the interest in dietary flavonoids has grown after the publication of several epidemiological studies showing an inverse correlation between dietary consumption of flavonols and flavones and reduced incidence and mortality from cardiovascular disease and cancer. In recent years, a large amount of experimental and some clinical data have accumulated regarding the effects of flavonoids on the endothelium under physiological and pathological conditions. The meta-analysis of seven prospective cohort studies concluded that the individuals in the top third of dietary flavonol intake are associated with a reduced risk of mortality from coronary heart disease as compared with those in the bottom third, after adju...

The meta-analysis of seven prospective cohort studies concluded that the individuals in the top third of dietary flavonol intake are associated with a reduced risk of mortality from coronary heart disease as compared with those in the bottom third, after adjustment for known risk factors and other dietary components. A limited number of intervention studies with flavonoids and flavonoid containing foods and extracts has been performed in several pathological conditions (PMID:17015250). Quercetin is isolated from many plants, especially fruits, such as Helichrysum, Euphorbia and Karwinskia spp. Present in the Solanaceae, Rhamnaceae, Passifloraceae and many other families.

Hypericin is a carbopolycyclic compound. It has a role as an antidepressant. It derives from a hydride of a bisanthene. Hypericin is a natural product found in Hypericum adenotrichum, Hypericum bithynicum, and other organisms with data available. Hypericin is an anthraquinone derivative that is naturally found in the yellow flower of Hypericum perforatum (St. Johns wort) with antidepressant, potential antiviral, antineoplastic and immunostimulating activities. Hypericin appears to inhibit the neuronal uptake of serotonin, norepinephrine, dopamine, gamma-amino butyric acid (GABA) and L-glutamate, which may contribute to its antidepressant effect. Hypericin may also prevent the replication of encapsulated viruses probably due to inhibition of the assembly and shedding of virus particles in infected cells. This agent also exerts potent phototoxic effects by triggering apoptotic signaling that results in formation of reactive oxygen species.
