Abstract

The present invention relates to vinyl bridge compound containing sulfonyl radical and diphenyl radical and in the general expression as shown. The present invention also relates to its preparation process and application in preparing medicine for inhibiting epoxy synthase 2 and medicine for treating inflammation and pain of mammal.

Description

technical field [0001] The present invention relates to the vinyl bridge compound that contains sulfonyl diphenyl group, particularly relate to the compound of general formula (I) and preparation method thereof, and the composition containing one or more these compounds, and this compound is in the preparation inhibition and epoxy Drug use for synthase 2-related diseases. [0002] Background technique [0003] Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used in the treatment of rheumatic diseases, inflammatory diseases, pain, soft tissue diseases and sports injuries due to their definite anti-inflammatory and analgesic effects. Disease and tumor prevention. Gastrointestinal complications are the most common side effects of long-term use of NSAIDs. The newly developed cyclooxygenase (COX-2) inhibitor can significantly reduce the occurrence of gastrointestinal complications while treating inflammation and pain. [0004] The pharmacological effects of NSAIDs...
