Synthesis of 2-hydroxychalcone derivatives and anti-tumor activity screening

Objective To design a synthetic route for 2,4-dihydroxychalcone derivatives, and to evaluate their in vitro anti-tumor activities. Methods The substance 2,4-dihydroxyacetophenone was used as staring material. After a series of reactions in four steps, 5-piperidyl-4-ethoxy-2-hydroxy-hydroxy-chalcone derivatives were obained.MTT assay was conducted to detect the prohibitive effects of the target compounds on cancer cell lines, including human gastric carcinoma cell line SGC-7901,colon cancer cell line SW-480,lymphocytic leukemia cell line L1210,and human breast cancer cell line MCF-7.Results Thirteen new compounds were prepared and their structures were confirmed by H-NMR. The in vitro screening showed that these compounds displayed promising anti-tumor activities. Conclusion The synthetic route is easy to operate. The chemical reactions are mild and environmentally friendly. The prepared compounds display promising anti-tumor activities and are worh further studying.
