<p>The invention provides compounds with antagonism against excitatory amino acid receptors, in particular, AMPA receptor having 6-substituted-7-heteroquinoxalinecarboxylic acid derivatives and addition salts thereof as effective ingredients, and processes for the preparation of both. These compounds relate to 6-substituted-7-heteroquinoxalinecarboxylic acid derivatives represented by a general formula (1) <CHEM> (wherein A denotes a single bond or methylene (CH2), Y denotes a nitrogen atom or =CH-, V denotes a single bond or methylene (CH2), T denotes a hydroxyl group, amino group, lower alkoxycarbonyl group, carboxyl group, aldehyde group or the like, Q denotes a halogen atom, lower alkyl group or lower alkoxy group, and R<1> denotes a hydroxyl group, lower alkoxy group or the like), and addition salts thereof.</p> |
