DNA-Binding and Cytotoxicity of Copper(I) Complexes Containing Functionalized Dipyridylphenazine Ligands.

ABSTRACT: A set of copper(I) coordination compounds with general formula [CuBr(PPh₃)(dppz-R)] (dppz-R = dipyrido[3,2-a:2',3'-c]phenazine (Cu-1), 11-nitrodipyrido[3,2-a:2',3'-c]phenazine (Cu-2), 11-cyanodipyrido[3,2-a:2',3'-c]phenazine (Cu-3), dipyrido[3,2-a:2',3'-c]phenazine-11-phenone (Cu-4), 11,12-dimethyldipyrido[3,2-a:2',3'-c]phenazine (Cu-5)) have been prepared and characterized by elemental analysis, ¹H-NMR and ³¹P-NMR spectroscopies as well as mass spectrometry. The structure of Cu-1 was confirmed by X-ray crystallography. The effect of incorporating different functional groups on the dppz ligand on the binding into CT-DNA was evaluated by absorption spectroscopy, fluorescence quenching of EtBr-DNA adducts, and viscosi
