The results showed that HL as a bidentate ligand coordinated with transition metal ions to form four-coordination complexes. The antibacterial activity was studied by using the filter scraps diffusion method, and the results indicated that the ligand and the complexes had a low bacteriostatic activity against S. Aureu, P. Aeruginosa and E. Coli. The low in vitro antitumor activity of the title complexes was also observed by using MTT method against KB, A2780, Bel7402 and HELF.展开更多
