Problems solved by technology

However, since the 1,2,3-triazole compounds synthesized by click chemistry have no active reaction sites, they can only be used as linking groups and cannot become building blocks, so triazole compounds cannot be used as combinatorial chemical compounds. Large-scale parallel synthesis of units; in the Huisgen azide-alkyne cycloaddition reaction, Cu(I) is also needed as a catalyst, which is very easy to cause some groups such as boronic acid groups to produce similar Suzuki coupling reactions and was cut off
In addition, Cu(I) is difficult to remove, there may be a certain amount of residue in the final product, and Cu(I) itself has certain cytotoxicity, which makes the activity test of the final product very likely to produce false positive or false negative results
The above shortcomings make the use of click chemistry to synthesize triazole compounds have certain limitations in medicinal chemistry research.

Description

technical field [0001] The invention belongs to the technical field of drug synthesis, and relates to a gold triazole compound, a preparation method and application thereof. Background technique [0002] Thioredoxin reductase (TrxR) is a NADPH-dependent dimeric selenase containing FAD domain, which belongs to the family of pyridine nucleotide-disulfide oxidoreductases. Together with thioredoxin and NADPH, it constitutes the thioredoxin system. TrxR has a variety of biological activities, can regulate the redox reaction of the body, and promote the growth and reproduction of cells. Many tumor cells highly express TrxR, and TrxR has a certain correlation with drug resistance of tumor cells: TrxR can maintain the stability of redox in the internal environment, and can defend against oxidative stress and cell mutation, promote cell growth, and inhibit cell apoptosis. Once normal cells are transformed into cancer cells, TrxR stimulates cell proliferation, transformation and ant...
