[Problem] To provide a compound which may be used for the prevention and/or treatment of diseases in which 5-HT2B receptor and 5-HT7 receptor are concerned, particularly for the treatment of irritable bowel syndrome (IBS).
[Means for Resolution] It was found that a pyrrole derivative characterized by the possession of a guanidinocarbonyl group or amido group as a substituent group at the 3-position, or a pharmaceutically acceptable salt thereof, has a strong antagonism for both of the 5-HT2B receptor and 5-HT7 receptor. In addition, the compound of the present invention having the antagonistic activity for both of the receptors showed a good pharmacological action in comparison with the case in which an antagonist selective for either one of the receptors was used alone. Based on the above, the compound of the present invention is useful for the prevention and/or treatment of diseases in which 5-HT2B receptor and 5-HT7 receptor are concerned, particularly for the treatment of irritable bowel syndrome (IBS).
[问题] 提供一种化合物,可用于预防和/或治疗与5-HT2B受体和5-HT7受体有关的疾病,特别是治疗肠易激综合征(IBS)。
[解决方法] 发现一种
吡咯衍
生物,其在3位具有
胍基羰基基团或酰胺基团作为取代基团,或其药学上可接受的盐,具有对5-HT2B受体和5-HT7受体的强烈拮抗作用。此外,本发明的化合物具有对两种受体的拮抗活性,与仅使用选择性拮抗剂的情况相比,表现出良好的药理作用。基于以上,本发明的化合物对于预防和/或治疗与5-HT2B受体和5-HT7受体有关的疾病,特别是治疗肠易激综合征(IBS)非常有用。
