Chemical Information
FooDB NameFisetin
Description3,7,3',4'-tetrahydroxyflavone, also known as 5-desoxyquercetin or fisetinidin, is a member of the class of 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. Thus, 3,7,3',4'-tetrahydroxyflavone is considered to be a flavonoid lipid molecule. 3,7,3',4'-tetrahydroxyflavone is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 3,7,3',4'-tetrahydroxyflavone is a bitter tasting compound found in soy bean, which makes 3,7,3',4'-tetrahydroxyflavone a potential biomarker for the consumption of this food product.

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
