The present invention relates to a compound represented by the following formula, a pharmacologically acceptable salt thereof, or a use thereof as a pharmaceutical:
wherein R1 and R2 are substituents adjacent to each other, and together with two carbon atoms to each of which they attach, form a 5- to 7-membered non-aromatic carbocyclic group or the like, which may be substituted by 1 to 4 substituents selected from (1) an oxo group, (2) a hydroxyl group, and the like; R3 represents a hydrogen atom or the like; and R6 represents a hydrogen atom or the like. This compound has a superior strength of binding to a 5-HT1A receptor and an antagonism to the receptor, and is useful as an agent for treating or preventing lower urinary tract symptoms, and particularly symptoms regarding urinary storage.
本发明涉及下式所代表的化合物、其药理学上可接受的盐,或其作为药物的用途:
其中 R1 和 R2 是彼此相邻的取代基,并与它们各自连接的两个碳原子一起构成 5 至 7 元的非芳香族碳环基团或类似基团,该基团可被 1 至 4 个选自(1)氧代基团、(2)羟基和类似基团的取代基取代;R3 代表氢原子或类似基团;R6 代表氢原子或类似基团。该化合物与 5-HT1A 受体的结合强度较高,对受体有拮抗作用,可作为治疗或预防下尿路症状,特别是储尿症状的药物。
