    Abstract:
    A series of [1,2,4]triazolo[4,3-b][1,2,4,5]tetrazine derivatives have been synthesized and evaluated for their antitumor activities. These compounds exhibited potent antiproliferative activities against MCF-7, Bewo and HL-60 cells and c-Met kinase inhibitory activities. Three compounds were highly effective against MCF-7, Bewo and HL-60 cells with IC50 values in 1.09-2.24μM. Molecular docking was further performed to study the inhibitor-c-Met kinase interactions, and the results show that compound 4j was potently bound to the c-Met kinase with three hydrogen bonds. The further research on acute toxicity and in vivo antitumor activity of compound 4j to ICR (Institute of Cancer Research) mice were carried out, and found 4j with a certain toxicity but good efficacy in vivo. Based on the preliminary results, it is deduced that compound 4j with potent c-Met kinase inhibitory activity may be a potential anticancer agent.
