Definition | ChEBI: Myricetin is a hexahydroxyflavone that is flavone substituted by hydroxy groups at positions 3, 3', 4', 5, 5' and 7. It has been isolated from the leaves of Myrica rubra and other plants. It has a role as a cyclooxygenase 1 inhibitor, an antineoplastic agent, an antioxidant, a plant metabolite, a food component, a hypoglycemic agent and a geroprotector. It is a hexahydroxyflavone and a 7-hydroxyflavonol. It is a conjugate acid of a myricetin(1-). |
Biochem/physiol Actions | Myricetin exerts anti-oxidant effects, and anti-inflammatory effects by regulating multiple signal pathways. It also displays anti-diabetic and hepatoprotective effects. Myricetin strongly inhibits yeast 伪-glucosidase, glyoxalase I in vitro, and bovine milk xanthine oxidase. It also promotes complex formation between DNA and both topoisomerase I and II, an effect that may have implications in cancer chemotherapy. Myricetin also has various nutraceuticals values and therapeutic effects. |
