ABSTRACT: A series of N-((1,3-diphenyl-1H-pyrazol-4-yl)methyl)aniline derivatives (5a-8d) have been designed and synthesized, and their biological activities were also evaluated as potential antitumor and cyclin dependent kinase 2 (CDK2) inhibitors. Among all the compounds, compound 5a displayed the most potent CDK2/cyclin E inhibitory activity in vitro, with an IC(50) of 0.98 ± 0.06 μM. Antitumor assays indicated that compound 5a owned high antiproliferative activity against MCF-7 and B16-F10 cancer cell lines with IC(50) values of 1.88 ± 0.11 and 2.12 ± 0.15 μM, respectively. Docking simulation was performed to insert compound 5a into the crystal structure of CDK2 at active site to determine the probable binding model. Based on the preliminary results, compound 5a with potent inhibitory activity in tumor growth may be a potential anticancer agent.
