Abstract

In an effort to detect potential inhibitors of cdc25 phosphatase, nineteen flavonoids belonging to the quercetin and kaempferol series have been evaluated, using a colorimetric assay of recombinant human cdc25A tyrosine phosphatase as a cell cycle-specific target. Compounds bearing two benzyl or methyl groups in positions 7 and 4′ and acetyl on the hydroxy groups of the sugar moiety showed the maximal activity.
