Problems solved by technology

[0009] Fortunately, after a lot of experiments, the inventor introduced hydrogen sulfide releasing groups into the structure of some compounds, and synthesized a series of compounds with brand new structures. The experimental results show that these compounds may have significant anti-inflammatory and anti-inflammatory properties. / or anti-tumor effect, or no obvious gastrointestinal damage, or both; in addition, new selective non-steroidal anti-inflammatory drugs such as celecoxib have less gastrointestinal damage , but fatal cardiovascular events

The compound is a compound with a general formula YLXYII or the salt of the compound, comprises the portion related with hydrogen sulfide and is often combined with compounds in covalence mode or forms the salt. Pharmacological results show that the compound has remarkable anti-inflammatory effect and tumor resistance without remarkable damage to gastrointestinal tract, so that the compound can be used for preparing and treating various diseases such as inflammation, cardiovascular diseases, and diseases related with tumor. In addition, the preparation method for preparing the compound is further provided.

Description

technical field [0001] The present invention relates to the field of medicine, in particular to several hydrogen sulfide donor compounds and pharmaceutically acceptable salts thereof, their preparation methods, pharmaceutical compositions containing these compounds and their medical uses, especially in the preparation of anti-inflammatory, anti- Applications in tumor and anti-cardiovascular disease drugs. Background technique [0002] There are complex and diverse signaling pathways in organisms and cells. Among them, gas signal molecules have attracted widespread attention in the scientific community due to their unique characteristics such as continuous production, rapid transmission, and rapid diffusion. The discovery of gas signal molecules has enabled biomedical research. Entered a new page. The first two gas signal molecules discovered were nitric oxide (NO) and carbon monoxide (CO). The former has been found to have a wide range of biological effects such as dilati...
