Synthesis and biological evaluation of 3-arylcoumarin derivatives as potential anti-diabetic agents

A variety of substituted 3-arylcoumarin derivatives were synthesised through microwave radiation heating. The method has characteristics of environmental friendliness, economy, simple separation, and purification process, less by-products and high reaction yield. Those 3-arylcoumarin derivatives were screened for antioxidant, α-glucosidase inhibitory and advanced glycation end-products (AGEs) formation inhibitory. Most compounds exhibited significant antioxidant and AGEs formation inhibitory activities. Anti-diabetic activity studies showed that compounds 11 and 17 were equipotent to the standard drug glibenclamide in vivo. According to the experimental results, the target compound 35 can be used as a lead compound for the development of new anti-diabetic drugs. The whole experiment showed that anti-diabetic activity is prevalent in 3-arylcoumarins, which added a new natural skeleton to the development of anti-diabetic active drugs.

Method for preparing 2,5-dimethylphenylacetic acid from 2,5-dimethylhalobenzene as raw material

The invention relates to the field of organic synthesis, in particular to a method for preparing 2,5-dimethylphenylacetic acid by taking 2,5-dimethylhalobenzene as a raw material, which comprises thefollowing steps of: reacting 2,5-dimethylhalobenzene with magnesium to generate Grignard reagent 2,5-dimethylphenyl magnesium halide; 2,5-dimethylphenylmagnesium halide reacts with ethylene oxide to generate 2,5-dimethylphenylethanol; 2,5-dimethylphenylethanol is oxidized to 2,5-dimethylphenylacetic acid by NaClO and NaClO2 under TEMPO or 4-OH TEMPO catalyst. The invention has the advantages thatthe use of expensive noble metal catalysts and highly toxic cyanidation reagents is avoided in the synthesis process of 2,5-dimethylphenylacetic acid, the reagents used are environment-friendly, the cost is reduced, the process is simplified, the yield is higher, the defects of the prior art are overcome, and the method is suitable for large-scale industrial production.
