Three square-planar complexes of Ni(II) with condensation derivative of 2-(diphenylphosphino)benzaldehyde and 4-phenylsemicarbazide and monodentate pseudohalides have been synthesized and characterized on the basis of the results of X-ray. NMR and IR spectroscopy and elemental analysis. Investigated complexes exhibited moderate antibacterial and cytotoxic activity. The most pronounced cytotoxic activity (in the range of cisplatin) to HeLa cell line was observed for ligand and all the complexes. Azido complex and ligand induced concentration dependent cell cycle arrest in the S phase, as well as decrease of percentage of cells in G1 phase, without significant increase of apoptotic fraction of cells. The interaction of the azido complex and ligand with CT-DNA results in changes in UV-Vis spectra typical for non-covalent bonding. The observed intrinsic binding constant of azido complex CT-DNA and ligand-CT-DNA were 3.22 x 10(5) M-1 and 2.79 x 10(5) M-1. The results of DNA cleavage experim...ents showed that azido complex nicked supercoiled plasmid DNA.
