[Problems] To provide a pharmaceutical, in particular a compound which can be used as a therapeutic agent for irritable bowel syndrome (IBS).
[Means for Solving Problems] It was found that a tetrahydroisoquinolin-1-one derivative having an amide group at the 4-position or a pharmaceutically acceptable salt thereof has an excellent bombesin 2 (BB2) receptor antagonistic action. It is also found that the tetrahydroisoquinolin-1-one derivative is highly effective on bowel movement disorders. From the above, the tetrahydroisoquinolin-1-one derivative of the present invention is useful as a therapeutic agent for diseases associated with a BB2 receptor, in particular IBS.
[问题] 提供一种药物,特别是一种可用作治疗肠易激综合征(IBS)的治疗剂。
[解决问题的方法] 发现一种在4位具有酰胺基团或其药学上可接受的盐的四氢异喹啉-1-酮衍生物具有优异的肽释放因子2(BB2)受体拮抗作用。还发现四氢异喹啉-1-酮衍生物对肠道运动障碍非常有效。由此可见,本发明的四氢异喹啉-1-酮衍生物对与BB2受体相关的疾病,特别是IBS,具有治疗剂的用途。
