Study of Umbelliferone Hydroxylation to Esculetin Catalyzed by Polyphenol Oxidase

open access: yesBiological and Pharmaceutical Bulletin, 2013
We characterize umbelliferone, a derivative of 2,4-dihydroxycoumaric acid, as a substrate of polyphenol oxidase. This enzyme hydroxylates umbelliferone to esculetin, its o-diphenol, and then oxidizes it to o-quinone. The findings show that umbelliferone, an intermediate in one of the coumarin biosynthesis pathways, may be transformed into its o ...
