Description

1. Technical field The present invention belongs to the technical field of medicine, and specifically relates to imidazopyridine derivatives containing dioxacyclopyridines, pharmaceutically acceptable salts and isomers thereof, methods for preparing these compounds, and pharmaceutical compositions containing these compounds. And the application of these compounds in the preparation of medicines for treating and / or preventing peptic ulcer. 2. Background technology Peptic ulcers are caused by ulceration of the gastrointestinal mucosa. These ulcers expose the bottom layer of the lining of the digestive tract to the acidic secretions of the stomach and pepsin. Cell autolysis occurs when there is an imbalance between the intestinal control). It is generally believed that peptic ulcer is caused by this autolysis. Peptic ulcer is one of the common frequently-occurring diseases, and the incidence of ulcer disease accounts for about 10% to 12% of the total population. The initia...
