title: Metal-based biologically active agents: Synthesis, characterization, antibacterial and antileukemia activity evaluation of Cu(II), V(IV) and Ni(II) complexes with antipyrine-derived compounds.
abstract: The paper presents the synthesis of complex combinations of Cu(II), V(IV) and Ni(II) with Schiff bases obtained through the condensation of 4-amino-1,5-dimethyl-2-phenyl-1H-3-pyrazol-3(2H)-one (antipyrine) with 2-hydroxybenzaldehyde, 4-hydroxy-5-methoxyisophthalaldehyde and 4,5-dihydroxyisophalaldehyde respectively. The characterization of newly formed complexes was done by (1)H NMR, (13)C NMR, UV-VIS, IR, EPR spectroscopies and molar electric conductibility studies. The effect of these complexes on proliferation of human leukemia cells (HL-60) and their antibacterial activity against Staphylococcus aureus var. Oxford 6538, Escherichia coli ATCC 10536 and Candida albicans ATCC 10231strains were studied and compared with those of free ligands.
