Coumarin-based, switchable fluorescent substrates for enzymatic bacterial detection [PDF]

Talanta, 2018
Enzymatically-switchable fluorescent substrates, such as the commercially available 4-methyl umbelliferones (4-MU) are used as standard indicators of enzymatic activity for the detection of various microorganisms and pathogens.

Umbelliferon: a review of its pharmacology, toxicity and pharmacokinetics

Inflammopharmacology, 2023
Coumarin, a plant secondary metabolite, has various pharmacological activities, including antioxidant stress and anti-inflammatory effects. Umbelliferone, a common coumarin compound found in almost all higher plants, has been extensively studied for its pharmacological effects in different disease models and doses with complex action mechanisms.

Uptake and modification of umbelliferone by various seedlings

Phytochemistry, 2019
Inspired by the recently discovered phenomenon of "horizontal natural product transfer" we investigated the putative uptake of phenolic specialized metabolites. Umbelliferone was chosen for this case study, since this coumarin as well as its derivatives can easily be determined by HPLC analyses. Barley (Hordeum vulgare L.), radish (Raphanus sativus L.),

A blue chemiluminescence in the reaction of umbelliferone with hypochlorite

Journal of Bioluminescence and Chemiluminescence, 1995
AbstractA strongly fluorescing 7‐hydroxycoumarin (umbelliferone, U) oxidized in dilute (10 μmol/L‐0, 1 mol/L) aqueous solution with CIO− or CIO− + H2O2 (but not with H2O2 alone) produces a strong chemiluminescence (CL). Light emission kinetics depends on the pH of solution (4.0–10.5) and the reaction has a low activation energy Ea = 31 ± 2 kJ/mol (285 ...

Antimicrobial properties of umbelliferone derivatives

Phytochemistry, 1971
Abstract The inhibitory effects of umbelliferone and a number of its alkyl and acyl derivatives on the growth of a variety of bacteria, yeasts and molds have been examined. Herniarin and similar alkyl ethers are more effective antimicrobial agents than umbelliferone.
