Embodiment 1

[0168] Embodiment 1: Preparation of (E)-2-(4-sulfonamidophenyl)-3-(3-methoxy-4-acetoxyphenyl)acrylic acid

[0169]

[0170] In a four-neck flask, add 0.25g (0.0013mol) of acetylvanillin to 10mL of acetonitrile solvent, add 0.4mL of triethylamine, stir to dissolve, then add 0.22g (0.001mol) of p-sulfonamide phenylacetic acid, and stir to react After 1 hour, DBU was added, the reaction was stirred for another 1 hour, and the reaction was stopped. About 10 mL of 1N hydrochloric acid was added, extracted with ethyl acetate, and the layers were separated. The ethyl acetate solution was washed with saturated brine, dried, and concentrated to obtain a yellow solid. Weight 0.06g. Thin layer, Rf is 0.3.

Abstract

The invention discloses a p-hydroxy phenyl acrylic acid derivative, which has a chemical structure expressed by general formula (I). The invention also discloses application of the p-hydroxy phenyl acrylic acid derivative to preparing COX-2 selective inhibitor medicament, and a pharmaceutical composition for treating and preventing pain, inflammation, rheumatoid arthritis, osteoarthritis or dysmenorrheal diseases, or antiviral and antibacterial pharmaceutical composition for treating and preventing virus and bacterial infection, or pharmaceutical composition for treating and preventing atherosclerosis, thrombosis, apoplexy or ischemia cerebrovascular diseases, wherein the pharmaceutical composition contains the p-hydroxy phenyl acrylic acid derivative or medicinal salt thereof with curative effective dose.

Description

technical field [0001] The present invention relates to a p-hydroxyphenylacrylic acid derivative and its application, in particular to a compound of general formula (I), a pharmacologically acceptable salt and hydrate, a preparation method thereof, and a composition containing one or more of these compounds , and the application of the compound in the preparation of COX-2 selective inhibitor drugs. Background technique [0002] Nonsteroidal 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, but gastrointestinal complications are long-term The most common side effect of taking NSAIDs drugs, the newly developed cyclooxygenase (COX2) inhibitor can significantly reduce the occurrence of gastrointestinal complications while treating inflammation and pain. [0003] Vioxx, a widely used cyclooxygenase inhibitor, ...
