This invention provides a compound of formula (I): wherein R1 represents an alkyl group having from 1 to 4 carbon atoms or a halogen atom, R2 represents an alkyl group having from 1 to 4 carbon atoms, R3 represents a hydrogen atom or a hydroxy group, and A represents an oxygen atom or a group of the formula —C(R4)(R5)— (in which R4 represents a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms and R5 represents a hydroxy group or an alkoxy group having from 1 to 4 carbon atoms) or a pharmaceutically acceptable salts thereof. These compounds have 5-HT4 receptor agonistic 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.
本发明提供了化合物(I)的结构式,其中R1代表具有1至4个碳原子的烷基或卤素原子,R2代表具有1至4个碳原子的烷基,R3代表氢原子或羟基,A代表氧原子或公式-C(R4)(R5)-的基团(其中R4代表氢原子或具有1至4个碳原子的烷基,R5代表羟基或具有1至4个碳原子的烷氧基),或其药学上可接受的盐。这些化合物具有5-HT4受体激动活性,因此对于哺乳动物,特别是人类的胃食管反流病、非溃疡性消化不良、功能性消化不良、肠易激综合征等治疗非常有用。
