Novel quinazolinone derivatives as 5-HT7 receptor ligands

5-HT7 receptor antagonists generated antidepressant-like effects in animal model and the involvement of the 5-HT7 receptor in other pathophysiological mechanisms such as thermoregulation, learning and memory, and sleep has been highl

Fused heterocyclic compounds and pharmaceutical applications thereof

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 D2receptor blocking action is administered. Therefore, the inventive compound can be used as a therapeutic agent for the diseases such as schizophrenia.
