The invention provides compounds with antagonism against excitatory amino acid receptors, in particular, AMPA receptor having 6-substituted heteroquinolinecarboxylic acid derivatives and addition salts thereof as effective ingredients, and processes for the preparation of both. These compounds relate to 6-substituted heteroquinolinecarboxylic acid derivatives represented by a general formula (1)
(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, R denotes a nitro group, trifluoromethyl group or halogen atom, and R1 denotes a hydroxyl group or lower alkoxy group), and addition salts thereof.
本发明提供了一种具有对兴奋性氨基酸受体的拮抗作用的化合物,特别是具有6-取代杂喹啉羧酸衍生物和其加成盐作为有效成分的AMPA受体,以及它们的制备方法。这些化合物涉及到由通式(1)表示的6-取代杂喹啉羧酸衍生物(其中,A表示单键或亚甲基(CH2),Y表示氮原子或═CH—,V表示单键或亚甲基(CH2),T表示羟基、氨基、低烷氧基羰基基团、羧基、醛基或类似物,R表示硝基基团、三氟甲基基团或卤素原子,R1表示羟基或低烷氧基基团),以及它们的加成盐。
