Application

3-Hydroxy-2-quinoxalinecarboxylic acid was used to study the sorption of ionizable organic compounds to an estuarine sediment. It was used in the preparation of Zinc(II)-quinoxaline complexes which was characterized by X-ray crystallography and fluorescence spectroscopy.

Biochem/physiol Actions

3-Hydroxy-2-quinoxalinecarboxylic acid is an antagonist of excitatory amino acids and possesses anticonvulsant properties. It inhibits the 22Na+ efflux produced in 22Na+-preloaded brain slices by N-methyl-D-aspartate and kainate.

The mid-IR and Raman spectra of 3-hydroxy-2-quinoxalinecarboxylic acid (3HQC) were recorded. These spectra were interpreted with the help of B3LYP/6-311++G(d,p) calculations and potential energy distribution (PED) analysis. As a result of the calculations, seven tautomers were determined among many stable

Various aromatic acids have been investigated as putative ligands of excitatory amino acid receptors. 3-Hydroxy-2-quinoxalinecarboxylic acid (HQC), at 1 mM, was found to antagonize the 22Na+ efflux produced in 22Na+-preloaded brain slices by N-methyl-D-aspartate and kainate. The response to glutamate

Three compounds reportedly blocking the N-methyl-D-aspartate (NMDA) receptor, namely 2-amino-5-phosphonovalerate, gamma-D-glutamylglycine and 3-hydroxy-2-quinoxalinecarboxylic acid, were injected subdurally onto the cortex of freely moving rats. All 3 compounds effectively suppressed behavioral and electrographic seizure activity induced by strychnine, morphine and picrotoxin

Zinc(ii)-quinoxaline complexes, [Zn(hqxc)(2)(py)(2)] and [Zn(hqxc)(2)(DMSO)(2)] (hqxc = 3-hydroxy-2-quinoxalinecarboxylate, py = pyridine, DMSO = dimethyl sulfoxide), were prepared and characterized by X-ray crystallography and fluorescence spectroscopy. In both complexes, the zinc ion is six-coordinated by two equatorial bidentate hqxc ligands with
