Method for synthesizing 2-aryl benzopyrone flavonoid derivatives

The invention relates to a method for synthesizing 2-aryl benzopyrone flavonoid derivatives, and relates to a method for synthesizing a compound, the method for synthesizing 2-aryl benzopyrone flavonoid derivatives is suitable for the synthesis of 2-aryl benzopyrone flavonoid derivatives containing different substituents. The method aims to solve the technical problems of low yield, long reactionperiod, and complicated post-treatment and high operation difficulty of the existing synthesis method of the ketone flavonoid derivative. The method comprises the following steps of: 1, preparing beta-propanedione compounds; 2, preparing flavonoid compound 2-aryl benzopyranones. The method completes esterification and rearrangement in one step, which is simple and practical, reduces intermediate links of reaction, saves separation and purification of intermediate products, improves utilization rate of raw materials, reduces reaction temperature, shortens reaction time under microwave radiation, reduces solvent consumption, the post-treatment is relatively simple, the yield is relatively high and no by-products exist, and can also react in the presence of a small amount of water, the reaction is easy to operate, and the method is suitable for industrial production. The method belongs to the technical field of compound synthesis.

Synthesis of novel 4,6-diaryl-2-aminopyrimidines as potential antiplasmodial agents

A novel series of 4,6-diaryl-2-aminopyrimidines 8a-o has been synthesized and evaluated for in vitro antiplasmodial activity against Plasmodium falciparum. Out of the 15 compounds synthesized and tested, 6 compounds have shown IC50 values in the range of 1.61-9.53 μg/mL. These compounds are several times more potent than chloroquine and quinine, the two standard drugs used for the purpose of comparison.

Assessment of antiplatelet activity of 2-aminopyrimidines

A series of 4,6-diaryl-2-aminopyrimidines was developed as antiplatelet agents and their potency was evaluated by in vitro assay. Compound 14k was found to be two times more potent than aspirin. These encouraging results could be helpful for the development of new antiplatelet compounds.

Synthesis and preliminary biological evaluation of chrysin derivatives as potential anticancer drugs

A series of chrysin derivatives were prepared from 2-hydroxyacetophenone, 2,4-dihydroxyacetophenone, 2,4,6-trihydroxy- acetophenone, using modified Baker-Venkataraman transformation. Their anticancer activities in vitro were evaluated by the standard MTT method. The results of biological test showed that some of chrysin derivatives showed stronger anticancer activity than 5-fluorouracil.
