NOTES
|
Luteolin analogue. Protein kinase inhibitor. Myricetin (3,3',4',5,5',7-Hexahydroxyflavone), Morin
(2',3,4',5,7-pentahydroxyflavone), Fisetin (3,3',4',7-Tetrahydroxyflavone) are naturally-occurring flavonoids. They have antioxidant properties which protect cells against oxygen radical damage. They are also reported inhibit xanthine oxidase, a free-radical generating enzyme and show and inhibit the oxidation of LDL (low density lipoprotein) by free radicals. Biochem/physiol Actions: Strongly inhibits yeast alpha-glucosidase, glyoxalase I in vitro, and bovine milk xanthine oxidase. Promotes complex formation between DNA and both topoisomerase I and II, an effect that may have implications in cancer chemotherapy. |
