Abstract

Phosphatidylinositol 3-kinase (PI3K) is one of the most attractive therapeutic targets for cervical Cancer treatment. In this study, we designed and synthesized a series of benzimidazole derivatives and evaluated their anti-cervical Cancer activity. Compound 4r exhibited strong antiproliferative activity in different cervical Cancer cell lines HeLa, SiHa and CA Ski, and relative lower cytotoxicity to normal hepatic and renal cell lines LO2 and HEK-293t (IC50 values were at 21.08 μM and 23.96 μM respectively). Its IC50 value was at 3.38 μM to the SiHa cells. Further mechanistic studies revealed that 4r induced Apoptosis, arrested cell cycle in G2/M phase, suppressed PI3K/Akt/mTOR pathway and inhibit the polymerization of tubulin. Molecular docking study suggested that 4r formed key H-bonds action with PI3Kα (PDB ID:8EXU) and tubulin (PDB ID:1SA0). Zebrafish acute toxicity experiments showed that high concentrations of 4r did not cause death or malformation of zebrafish embryos. All these results demonstrated that 4r would be a promising lead candidate for further development of novel PI3K and tubulin dual inhibitors in cervical Cancer treatment.
