AB  - Complexes 1-4, [Ru(L)(bpy)(2)]PF6, where bpy=2,2-bipyridine; HL=3-methylpyridine-2-carboxylic acid (HL1), 6-methylpyridine-2-carboxylic acid (HL2), 5-bromopyridine-2-carboxylic acid (HL3) and 6-bromopyridine-2-carboxylic acid (HL4), were synthesized and characterized. The electrochemical character of the complexes was investigated by cyclic voltammetry revealing two reversible reduction waves in the negative range of potentials, most likely due to a reduction of the bipyridine moiety. Cytotoxicity studies by MTT assay for 72h of drug action revealed that 2-4 exhibited moderate activity in cervical human tumor cells (HeLa). Complex 2 exhibited low activity in colon cancer LS-174 cells (180 +/- 10), while all complexes were devoid of activity in lung cancer A549 and non-tumor MRC-5 cells, up to 200M. Combinational studies of the most active complex 2, with pharmacological modulators of cell redox status, L-buthionine-sulfoximine (L-BSO) or N-acetyl-L-cysteine (NAC), showed that when L-BSO potentiated, 2 induced a sub-G1 peak of the cell cycle in the HeLa cell line. UV-vis and cyclic voltammetry were performed in order to investigate the binding mode of 2 to DNA and suggested intercalation for the complex-DNA interaction. [GRAPHICS]

AB  - A new Ru(II) bipyridyl complex with O-4-hydrogenpyridine-2,4-dicarboxylate was synthesized and characterized by IR, NMR and mass spectrometry, X-ray diffraction analysis and elemental analysis. The electrochemical characteristics of the complex were investigated by cyclic voltammetry, revealing Ru(II)/Ru(III) electron transfer in the positive range of potentials. On the opposite potential side, multiple partially reversible peaks were dominant, representing subsequent reductions of the bulky bipyridyl moiety. The cytotoxic activity of the complex was tested in two human cancer cell lines: A549 (lung cancer) and K562 (leukemia) as well as non-tumor MRC-5 cells, by MTT assays. The IC50 values were GT 300 and 177.63+/-2.28 mu M for the A549 and K562 cells, respectively.
