Chemical Information
FooDB NameQuercetin
DescriptionQuercetin, also known as sophoretin or xanthaurine, belongs to the class of organic compounds known as flavonols. Flavonols are compounds that contain a flavone (2-phenyl-1-benzopyran-4-one) backbone carrying a hydroxyl group at the 3-position. Quercetin is an antioxidant, like many other phenolic heterocyclic compounds. Quercetin is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Quercetin is a widely distributed flavonoid found in many plants and fruits including red grapes, citrus fruit, tomatoes, broccoli, red onions, kale, various leafy green vegetables, and a number of berries, including raspberries and cranberries. In plants quercetin functions as a naturally occurring polar auxin transport inhibitor (PMID: 12237347). Quercetin has a bitter flavor and is used as an ingredient in dietary supplements, beverages, and foods. Quercetin itself (the aglycone), 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. In the human body quercetin functions as a non-specific protein kinase enzyme inhibitor (PMID: 15019969). It also acts as a phytoestrogen and has been reported to have estrogenic activities by activating both estrogen receptor alpha (ER alpha) and estrogen beta (ER beta) (PMID: 17724002). In human breast cancer cell lines, quercetin has been found to act as an agonist of the G protein-coupled estrogen receptor (GPER) (PMID: 15090535). Despite these many known interactions with human proteins, quercetin has not been confirmed scientifically as a specific therapeutic for any condition nor been approved by any regulatory agency. In particular, the U.S. Food and Drug Administration has not approved any health claims for quercetin. Nevertheless, there is a clear 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 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).

    ornithine-decarboxylase inhibitor23924 A compound or agent that combines with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction.DUKE
    pesticide25944 Strictly, a substance intended to kill pests. In common usage, any substance used for controlling, preventing, or destroying animal, microbiological or plant pests.DUKE
    prostaglandin-E2 inhibitor35222 A substance that diminishes the rate of a chemical reaction.DUKE
    phospholipase inhibitor23924 A compound or agent that combines with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction.DUKE

    TNF-alpha inhibitor35222 A substance that diminishes the rate of a chemical reaction.DUKE
    topoisomerase-II inhibitor50750 A topoisomerase inhibitor that inhibits DNA topoisomerase (ATP-hydrolysing), EC 5.99.1.3 (topoisomerase II), which catalyses ATP-dependent breakage of both strands of DNA, passage of the unbroken strands through the breaks, and rejoining of the broken strands.DUKE
    topoisomerase-I inhibitor50276 A topoisomerase inhibitor that inhibits the bacterial enzymes of the DNA topoisomerases, Type I class (EC 5.99.1.2) that catalyze ATP-independent breakage of one of the two strands of DNA, passage of the unbroken strand through the break, and rejoining of the broken strand. These bacterial enzymes reduce the topological stress in the DNA structure by relaxing negatively, but not positively, supercoiled DNA.DUKE
    tumorigenic50903 A role played by a chemical compound which is known to induce a process of carcinogenesis by corrupting normal cellular pathways, leading to the acquistion of tumoral capabilities.DUKE
    tyrosinase inhibitor59997 Any EC 1.14.18.* (oxidoreductase acting on paired donors, miscellaneous compound as one donor, incorporating 1 atom of oxygen) inhibitor that interferes with the action of tyrosinase (monophenol monooxygenase), EC 1.14.18.1, an enzyme that catalyses the oxidation of phenols (such as tyrosine) and is widespread in plants and animals.DUKE
    tyrosine-kinase inhibitor23924 A compound or agent that combines with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction.DUKE
    vasodilator35620 A drug used to cause dilation of the blood vessels.DUKE
    VEGF inhibitor35222 A substance that diminishes the rate of a chemical reaction.DUKE
    xanthine oxidase inhibitor35634 An EC 1.17.3.* (oxidoreductase acting on CH or CH2 with oxygen as acceptor) inhibitor that interferes with the action of xanthine oxidase (EC 1.17.3.2).DUKE
    protein kinase inhibitor37699 An EC 2.7.* (P-containing group transferase) inhibitor that interferes with the action of protein kinases.CHEBI
