Imidazo[4,5-b] pyridine compounds, process for preparing same and pharmaceutical compositions containing same.

摘要

Imidazo[4,5-b]pyridine compounds of the general formula [I] are provided: <CHEM> where R<1> is straight-chain or branched C1-8 alkoxy (which may be substituted with cycloalkyl) or C2-4 fluoroalkyloxy, R<2> is H, methyl or methoxy, and R<3> and R<4> are each H or methyl and may be the same or different. All these compounds exhibit good inhibition of potassium ion-dependent adenosine triphosphatase and excellent storage stability, so that they are usable for the treatment of gastric and/or duodenal ulcers.
