Synthesis, biological evaluation, and molecular docking studies of N,1,3-triphenyl-1H-pyrazole-4-carboxamide derivatives as anticancer agents

A series of N,1,3-triphenyl-1H-pyrazole-4-carboxamide derivatives have been designed, synthesized and evaluated for their potential antiproliferation activity and Aurora-A kinase inhibitory activity. Among all the compounds, compound 10e possessed the most potent biological activity against HCT116 and MCF-7 cell lines with IC50 values of 0.39 ± 0.06 μM and 0.46 ± 0.04 μM, respectively, which were comparable to the positive control. Compound 10e also exhibited significant Aurora-A kinase inhibitory activity (IC50 = 0.16 ± 0.03 μM). Docking simulation was performed to position compound 10e into the active site of Aurora-A kinase, in order to get the probable binding model for further study. The results of Western-blot assay demonstrated that compound 10e possessed good Aurora-A kinase inhibitory activity against HCT116. Based on the preliminary results, it is deduced that compound 10e with potent Aurora-A kinase inhibitory activity may be a potential anticancer agent.
