This invention provides a compound of the formula (I):
or a pharmaceutically acceptable salt thereof, wherein
R1 represents a hydrogen atom or a halogen atom;
R2 represents a methyl group or an ethyl group;
R3 represents a branched alkyl group having from 3 to 6 carbon atoms or an alkyl group having from 3 to 6 carbon atoms substituted by an alkoxy group having from 1 to 6 carbon atoms;
with the proviso that when the terminal carbon atom of said alkyl group of R3 is substituted by said alkoxy group, said alkyl group is a branched alkyl group.
These compounds have 5-HT4 receptor binding activity, and thus are useful for the treatment of gastroesophageal reflux disease, non-ulcer dyspepsia, functional dyspepsia, irritable bowel syndrome or the like in mammalian, especially humans. This invention also provides a pharmaceutical composition comprising the above compound.
本发明提供了式(I)的化合物或其药学上可接受的盐,其中R1代表氢原子或卤素原子;R2代表甲基基团或乙基基团;R3代表分支烷基基团,其具有3至6个碳原子,或者是具有3至6个碳原子的烷基基团,其被1至6个碳原子的烷氧基取代;但是当R3的烷基基团的末端碳原子被所述的烷氧基取代时,该烷基基团是分支烷基基团。这些化合物具有5-HT4受体结合活性,因此对于哺乳动物,特别是人类的治疗胃食管反流病、非溃疡性消化不良、功能性消化不良、肠易激综合征或类似疾病非常有用。本发明还提供了包含上述化合物的药物组合物。
