Synthesis and antitumor evaluation of 2,3-diarylbenzofuran derivatives on HeLa cells
摘要:
2,2-Dihydroxyarylethanones, readily prepared from the commercially available aromatic ethyl ketones, were reacted with resorcinol, 3-methoxyphenol or 2-methoxyphenol in multi steps one-pot manner promoted by trifluoroacetic acid to furnish the 2,3-diarylbenzofuran derivatives in 22-95% yield. Sixteen targeted compounds were synthesized and characterized by H-1 NMR, C-13 NMR and HRMS. MIT assay indicated that most compounds possessed effectively inhibitory activities against the proliferation of HeLa cell. Among them, 4f had the highest inhibitory activities, with the IC50 being 13.40 +/- 2.04 mu mol/L. Cell cycle analysis, Annexin V-FITC/propidium iodide dual staining assay and western blotting analysis revealed that 4f inhibited the proliferation of Hela cell through apoptosis induction in a dose-dependent manner via obviously up-regulated the levels of Bak and Bim, while striking down regulated the level of Bcl-2 and BcI-xL protein.

operationally simple approach for the synthesis of novel isoxazolyl amino furo[3,2-c]quinolinone derivatives by a one-pot three-component reaction of 4-amino-3-methyl-5 styrylisoxazoles, aryl glyoxal monohydrates and 4-hydroxy-1-methyl-2-quinolinone using p-TSA as the catalyst in aqueous medium was developed. The protocol proves to be an efficient and an environmentallybenign in terms of high yields, operational
