[Problem] Provided is a compound having a positive allosteric modulating activity (PAM activity) on an α7 nicotinic acetylcholine receptor (α7 nACh receptor).
[Means for Solution] The present inventors have studied on a PAM activity on an α7 nACh receptor, and they have found that a tetrahydrooxepinopyridine compound has a PAM activity on an α7 nACh receptor, thereby completing the present invention. The tetrahydrooxepinopyridine compound of the present invention has a PAM activity on an α7 nACh receptor and can be expected as an agent for preventing or treating dementia, cognitive impairment, schizophrenia, Alzheimer's disease, CIAS, negative symptoms of schizophrenia, inflammatory diseases, or pain.
提供的是一种对α7尼古丁乙酰胆碱受体(α7 nACh受体)具有正向别构调节活性(PAM活性)的化合物。解决方法是,本发明者研究了α7 nACh受体上的PAM活性,并发现一种四氢氧杂环吡啶化合物在α7 nACh受体上具有PAM活性,从而完成了本发明。本发明的四氢氧杂环吡啶化合物在α7 nACh受体上具有PAM活性,并可望作为预防或治疗痴呆、认知障碍、精神分裂症、阿尔茨海默病、CIAS、精神分裂症的消极症状、炎症性疾病或疼痛的药剂。
