A simple umbelliferone based fluorescent probe for the detection of nitroreductase [PDF]
, 2018 A simple nitrobenzyl-umbelliferone (NCOU1) was synthesised containing a nitroreductase (NTR) trigger moiety. The presence of NTR, resulted in the fragmentation of the parent molecule and release of the highly emissive fluorophore umbelliferone via an NTR-

Study of Umbelliferone Hydroxylation to Esculetin Catalyzed by Polyphenol Oxidase
Biological 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 ...
