Low-dimensional compounds containing bioactive ligands. Part VIII: DNA interaction, antimicrobial and antitumor activities of ionic 5,7-dihalo-8-quinolinolato palladium(II) complexes with K+ and Cs+ cations

Six new Cat[PdCl2(XQ)] complexes (Cat = K+ or Cs+, XQ = biologically active halogen derivatives of quinolin-8-ol) were synthesized by cationic exchange between NH2(CH3)2+ and alkali metals cations. All prepared complexes were characterized by IR, UV-VIS, NMR, elemental and thermal analyses, and their interaction to DNA, antimicrobial and antitumor activities were evaluated.219
