The present invention provides new fused imidazole compounds of the formula:
wherein A is a lower alkylene radical, R' is a hydrogen or halogen atom or a lower alkyl or lower alkoxy radical, R2 is a hydrogen atom or a lower alkyl, cyclo(lower)alkyl, pyridyl, ar(lower)alkyl, which may be substituted by halogen, or aryl radical, which may be substituted by lower alkyl, lower alkoxy, hydroxy or halogen, R3 is an N-containing unsaturated heterocyclic radical, which may be substituted by lower alkyl or amino, and Y is =C- or =N-, and the pharmaceutically-acceptable salts thereof; and processes for the preparation thereof, as well as pharmaceutical compositions comprising them.
These new compounds and the salts thereof are useful as anti-ulcer agents.
本发明提供了式如下的新的融合咪唑化合物:
其中A是低级亚烷基,R'是氢原子或卤素原子或低级烷基或低级烷氧基,R2是氢原子或可被卤素取代的低级烷基、环(低)烷基、吡啶基、芳(低)烷基或芳基、可被低级烷基、低级烷氧基、羟基或卤素取代的芳基,R3 是可被低级烷基或氨基取代的含 N 的不饱和杂环基,Y 是 =C- 或 =N-,以及它们的药学上可接受的盐;及其制备工艺,以及包含它们的药物组合物。
这些新化合物及其盐类可用作抗溃疡剂。
