  This invention provides compounds which are represented by a general formula [I] 1 [in which X stands for hydrogen or halogen; B stands for halogen, cyano or optionally fluorine-substituted lower alkyl; D stands for a 3-10 membered aliphatic nitrogen-containing heterocyclic group; R 3 , R 4 and R 5 may be same or different, and each stands for hydrogen, lower alkyl optionally having substituent group(s) and the like; and a is 0 or 1]. These compounds exhibit high affinity to nociceptin receptors and whereby inhibit actions of nociceptin, and are useful as an analgesic, antiobestic, agent for ameliorating brain function, treating agents for Alzheimer's disease and dementia, and therapeutic agents for schizophrenia, neurodegenerative diseases, depression, diabetes insipidus, polyuria, hypotension and the like.

  这项发明提供了一些化合物，它们由一般式[I]1表示，其中X代表氢或卤素；B代表卤素、氰基或者可选的含氟低碳基；D代表一个3-10个成员的脂肪氮杂环基团；R3、R4和R5可能相同也可能不同，每个代表氢、可选的取代基的低碳基等；a为0或1。这些化合物表现出高亲和力对于痛觉受体，并抑制痛觉素的作用，因此可用作镇痛剂、抗肥胖剂、改善脑功能的药物、治疗阿尔茨海默病和痴呆症的药物、以及治疗精神分裂症、神经退行性疾病、抑郁症、尿崩症、多尿症、低血压等的治疗剂。
