Its reactions with Pt(II) and Ru(II) afforded three metal complexes: cis-[PtCl2(L)] (1), cis-[PtCl2(L)(DMSO)] (2), and cis-[RuCl2(L)(DMSO)(2)]center dot 1.5H(2)O (3), the crystal structures of L, 2 and 3 were determined by single-crystal X-ray diffraction methods. These complexes were fully characterized by elemental analysis, IR spectrophotometry, H-1 and C-13 NMR spectroscopies, and ES mass spectrometry. The in vitro cytotoxicity of L and complexes 1-3 against 11 human tumour cell lines was assayed. The metal-based compounds exhibit enhanced cytotoxicity vs. free L, suggesting that these compounds display synergy in the combination of metal ions and liriodenine. The binding properties of L and its complexes 1-3 to ct-DNA were investigated through UV-vis, fluorescence, CD spectra, viscosity and agarose gels electrophoretic measurements.}, keywords = {AFFINITY, ALKALOIDS, CISPLATIN, CYTOTOXIC ACTIVITY, DRUGS, FLUORESCENCE, IN-VITRO, PLATINUM(II) COMPLEXES, RUTHENIUM(II) COMPLEXES, TOPOISOMERASE-II}, isbn = {1477-9226}, url = {://000261807400006}, author = {Chen, Z.
