A series of novel Schiff base compounds containing pyrazole group were synthesized with pyrazole aldehyde and benzene hydrazine or pyrazole aldehyde and phenylhydrazine hydrochloride as the starting materials. As-synthesized Schiff base compounds were characterized by means of nuclear magnetic resonance spectroscopy, infrared spectrometry, mass spectrometry and elemental analysis. Moreover the in vitro antitumor activity of compounds B2 and B4 against K562 (human leukemia cell line) was evaluated using MTT assay method. Results show that the compounds can inhibit K562 tumor cells growth and generation.
