Abstract

A series of 1,3,4-thiadiazole derivatives containing 1,4-benzodioxan (2a-2s) have been synthesized to screen for FAK inhibitory activity. Compound 2p showed the most potent biological activity against HEPG2 cancer cell line (EC(50)=10.28 μg/mL for HEPG2 and EC(50)=10.79 μM for FAK), which was comparable to the positive control. Docking simulation was performed to position compound 2p into the FAK structure active site to determine the probable binding model. The results of antiproliferative and Western-blot assay demonstrated that compound 2p possessed good antiproliferative activity against HEPG2 cancer cell line. Therefore, compound 2p with potent FAK inhibitory activity may be a potential anticancer agent against HEPG2 cancer cell.
