An object of the present invention is to provide a novel and excellent agent for treating or preventing dementia, schizophrenia and the like, based on the 5-HT
5A
receptor modulating action. It was confirmed that a compound characterized by a structure that a tricyclic hetero ring having a pyrrole ring at the center and guanidine are bonded via a carbonyl group has a potent 5-HT
5A
receptor modulating action and an excellent pharmacological action based thereon, and thus, it was found that the compound can be an excellent agent for treating or preventing dementia, schizophrenia, bipolar disorder, or attention deficit hyperactivity disorder, particularly for memory-related functional disorders such as cognitive impairments including dementia and schizophrenia, thereby completing the present invention.
本发明的目的是提供一种基于5-HT5A受体调节作用的新型优良的治疗或预防痴呆症、精神分裂症等药剂。经证实,一种以三环杂环在中心具有吡咯环,并通过羰基结合了胍的结构特征化合物具有强效的5-HT5A受体调节作用和基于此的优良药理作用,因此,发现该化合物可以成为治疗或预防痴呆症、精神分裂症、躁郁症或注意力缺陷多动障碍等的优良药剂,特别是对于认知障碍包括痴呆症和精神分裂症等的记忆相关功能障碍,从而完成了本发明。
