查询词典 zinc

Benzaldehyde nitrogen mustard isonicotinoyl hydrazone was synthesized according to literature method. The copper , cobalt , nickel , chromium , iron , zinc and cadmium complexes of it were prepared and characterized by elemental analysis, IR, UV-vis, NMR and EPR spectra. The cytotoxicity effect of the complexes was examined on SMMC-7721 cell line. Results show that the complexes have definite antitumor activity and the synergic effect between chromium and the ligand.
