In the structure of the title compound, C10H6O4, there is a single intramolecular hydrogen bond. In addition, there are a number of significant intermolecular C-H...O attractive interactions. These interactions account in part for the rather high density for an ordinary
A series of coumarin-3-acyl derivatives have been synthesized and investigated for the ability to inhibit selectively monoamine oxidases. The coumarin-3-carboxylic acids, 2a-e, proved to be reversible and selective inhibitors of the MAO-B isoform, displaying pIC(50) values of particular interest: 2a
The radiation-induced reactions of a water-soluble coumarin derivative, coumarin-3-carboxyl acid (C3CA), have been investigated in aqueous solutions by pulse radiolysis with a 35 MeV electron beam, final product analysis following (60)Co γ-irradiations and deterministic model simulations. Pulse radiolysis revealed that
The process of heat-induced generation of hydroxyl radicals in seawater was studied using coumarin-3-carboxylic acid as a fluorescent detector of .OH. The rate constants of .OH thermoproduction were determined in the temperature range of 40 to 60 degrees C. The

The spectral evolution of three photoactive proteins has been investigated by measuring the fluorescence with good temporal and wavelength resolution and a high signal-to-noise ratio. Upon excitation at 400 nm wild-type (wt) PYP both at neutral pH and in the
