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. The compounds are 6-substituted-7-heteroquinoxalinecarboxylic acid derivatives represented by the formula (1)
where 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 R1 denotes a hydroxyl group, lower alkoxy group or the like, and addition salts thereof.
该发明提供了具有对兴奋性氨基酸受体拮抗作用的化合物,特别是具有6-取代-7-杂喹啉羧酸衍生物及其盐作为有效成分的AMPA受体,以及两者的制备方法。这些化合物是由式(1)表示的6-取代-7-杂喹啉羧酸衍生物,其中A表示一个单键或亚甲基(CH2),Y表示一个氮原子或═CH—,V表示一个单键或亚甲基(CH2),T表示一个羟基、氨基、较低的烷氧羰基、羧基、醛基或类似物,Q表示一个卤原子、较低的烷基或较低的烷氧基,R1表示一个羟基、较低的烷氧基或类似物,以及它们的盐。
