摘要

6-Substituted-7- heteroquinoxaline carboxylic acid derivatives represented by general formula (1) and addition salts thereof, exhibiting antagonism against excitatory amino acid receptors, particularly AMPA receptor; and processes for the preparation of both (1) wherein A is a single bond or methylene (CH2); Y is nitrogen or =CH-; V is a single bond or methylene (CH2); T is hydroxyl, amino, lower alkoxycarbonyl, carboxyl, formyl, or the like; Q is halogeno, lower alkyl, or lower alkoxy; and R<1> is hydroxyl, lower alkoxy, or the like.
