title: [Selective anticonvulsive action of N-substituted imidazole-4,5-dicarboxylic acids against quinolinic acid].
abstract: Selective antagonists of quinolinic acid (2,3-pyridine dicarboxylic acid, QUIN)--an endogenous convulsant tryptophan metabolite, administered intracerebroventricular to mice, were identified during comparison with the following intracerebroventricular convulsants: l-kynurenine, aspartic, glutamic, N-methyl-DL-aspartic and kainic acids. It is suggested that the antagonism arises due to a common fragment of the structure which consists of two carboxylic groups at two nearest carbon atoms of the ring and of one nitrogen atom in the alpha-position. The selective action of the compounds found against QUIN supports the suggestion that QUIN produces seizures via N-methyl-D-aspartate binding sites.
