The present invention relates to a fused heterocyclic compound of the formula (I)
wherein each symbol is as defined in the specification, an optical isomer thereof, a pharmaceutically acceptable salt thereof, a pharmaceutical composition containing a compound of the formula (I), an optical isomer thereof or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable additive, and a medicament containing a compound of the formula (I), an optical isomer thereof or a pharmaceutically acceptable salt thereof. The compound of the present invention is a useful antipsychotic agent effective not only for positive symptoms centering on hallucination and delusion characteristic of the acute stage of schizophrenia, but also negative symptoms of apathy, abulia and autism. The inventive compound is expected to make a highly safe antipsychotic agent associated with less side effects, such as extrapyramidal symptoms and endocrine disturbance, which are observed when a conventional antipsychotic agent having a D2 receptor blocking action is administered. Therefore, the inventive compound can be used as a therapeutic agent for the diseases such as schizophrenia.
本发明涉及式(I)的融合杂环化合物、其光学异构体、其药用盐、含有式(I)化合物、其光学异构体或其药用组合物的药物组合物。
其中各符号如说明书中所定义;其光学异构体;其药学上可接受的盐;含有式(I)化合物、其光学异构体或其药学上可接受的盐和药学上可接受的添加剂的药物组合物;以及含有式(I)化合物、其光学异构体或其药学上可接受的盐的药物。本发明的化合物是一种有用的抗精神病药物,不仅对精神分裂症急性期特有的以幻觉和妄想为中心的阳性症状有效,而且对冷漠、乏力和自闭等阴性症状也有效。本发明化合物有望成为一种高度安全的抗精神病药物,其副作用较小,如锥体外系症状和内分泌紊乱,这些副作用在使用具有 D2 受体阻断作用的传统抗精神病药物时会出现。因此,本发明化合物可用作精神分裂症等疾病的治疗药物。
