AB  - Mono and dinuclear p-cymene-ruthenium(II) complexes [RuCl(L-1)(eta(6)-p-cymene)]Cl, where L-1 is propionic acid hydrazide (1) and [Ru2Cl2(L-2)(eta(6)-p-cymene)2], where H2L2 is N-1,N-2-dipropionylhydrazine (2), were prepared by a reaction of [RuCl2(eta(6)-p-cymene)](2) with the corresponding ligand precursor. Upon the reaction of [RuCl2(eta(6)-p-cymene)](2) with butyric acid hydrazide and pentanoic acid hydrazide in a 1:1 molar ratio in situ formation of tetradentate bridging ligands, N-1,N-2-dibutanoylhydrazine and N1,N2-dipentanoylhydrazine, respectively, occurred and the dinuclear complexes [Ru2Cl2(L-3)(eta(6)-p-cymene)2] (3) and [Ru2Cl2(L-4)(eta(6)-p-cymene)(2)] (4) were isolated. The compounds were characterised by elemental analysis, ESI-mass spectrometry, IR and 1D and 2D NMR spectroscopies. The structures of all complexes were established using single crystal X-ray crystallography. According to these data in both the mono- and dinuclear complexes the ruthenium atoms adopt the usual three-leg piano-stool geometry which is common for this type of complexes. Combining DFT calculations with the characterisation of the final products using X-ray diffraction, a possible reaction mechanism was discussed.

AB  - Three new ruthenium(II)-earene halido complexes of general formula [(eta(6-)p-cymene)RuX(L)] (C1-C3) were synthesised by reaction of [(eta(6)-p-cymene)RuX2](2) (X- = Cl-, Br-, I-) with 1H-benzimidazole-2-carboxylic acid (HL) in ethanol. The complexes were characterised by elemental analysis, mass spectrometry, IR, H-1 and C-13 NMR spectroscopy. The 1H-benzimidazole-2-carboxylate was found to act as a bidentate N,-Oechelating ligand. Single-crystal X-ray diffraction analysis confirmed the "piano-stool" geometry of C3. The cytotoxic activity of the ligand precursor and ruthenium complexes was tested in human cancer cell lines: cervical carcinoma (HeLa), breast carcinoma (MDA-MB-231), myelogenous leukemia (K562) as well as in one normal human fetal lung fibroblast cell line (MRC-5), by MTT assay. The results show that ruthenium(II)-arene complexes possess enhanced cytotoxicity when compared to that of HL. The latter was devoid of activity in the range of concentrations up to 300 mu M. Complex C3, carrying an iodido leaving ligand, exhibited moderate, but selective cytotoxicity toward HeLa, MDA-MB-231 and K562 cell lines, with IC50 values: 73.7, 60.9 and 53.9 mu M, respectively, being less toxic against MRC-5 cells (IC50 - 175.9 mu M). Complexes C1 and C2 showed moderate to low cytotoxicity in HeLa and K562 cells. (C) 2016 Elsevier B.V. All rights reserved.

AB  - Metal semicarbazone and thiosemicarbazone complexes have attracted much attention due to their diverse biological activities. Because of the ability of ruthenium(II)-arene species to coordinate to different classes of ligands, they are suitable for fine-tuning chemical and pharmaceutical properties. Ruthenium(II) arene-complexes containing different types of ligands: namely caprylic hydrazide (a hydrazide with a long hydrocarbon chain), isonicotinic acid hydrazide (a hydrazide with an aromatic pyridine ring), thiosemicarbazones and semicarbazones (derived from the reaction of 3- and 4-acetylpyridine with either thiosemicarbazide or caprylic hydrazide), were obtained in the reaction of [(eta(6)-p-cymene)RuCl2](2) with the corresponding ligands in a 1:2 or 1:2.2 molar ratio in methanol, ethanol or isopropanol with mild heating. The complexes were characterized by elemental analysis, mass spectrometry, IR and NMR spectroscopies. The structure of complex 1 was determined by X-ray crystallography. Antiproliferative activity of the investigated complexes, determined for three human cancer cell lines (HeLa, A549 and LS-174) revealed moderate activity without significant influence on the matrix metalloproteinases (MMP-2 and MMP-9) activity.

AB  - Two ruthenium(II) complexes of 2-acetylpyridine N ',N '-dimethylthiosemicarbazone (HL1) and phenanthrenequinone thiosemicarbazone (HL2), namely [(RuCI)-C-II(L-1)(PPh3)(2)] (1) and [(RuCl)-Cl-II(L-2) (PPh3)(2)] (2), have been synthesised and characterised by IR, UV/Vis and NMR spectroscopy, electrospray mass spectrometry, cyclic voltammetry and X-ray crystallography. In addition, the X-ray crystal structure of [(RuCl2)-Cl-III(L-2)- PPh3]center dot dmso center dot 1.25H(2)O (3 center dot dmso center dot 1.25H(2)O) is reported. The reaction of [(RuCl2)-Cl-II(dmsO)(4)] with HL1 and 1,3,5-triaza-7-phosphaadamantane (PTA) gives the highly water-soluble complex [(RuCl)-Cl-II(L-1)(HPTA)(2)]Cl-2 center dot C2H5OH center dot H2O (4 center dot C2H5OH center dot H2O) (S-25 degrees C - gt = 250 mg/mL), which has been fully characterised. Complex 4 shows strong antiproliferative effects in low micromolar concentrations in the ovarian carcinoma cell line 41M (IC50 = 0.87 mu m) and more moderate activity in the breast cancer cell line SK-BR-3 (IC50 = 39 mu m). The activity of the compound is 6.5- and 5.4-times higher at pH = 6.0 than at pH = 7.4 in the non-small cell lung cancer cell line A549 and the colon carcinoma cell line HT-29 (GI(50) = 24 and 8.0 mu m at pH = 6.0 for A549 and HT-29, respectively).

abstract = "Two ruthenium(II) complexes of 2-acetylpyridine N ',N '-dimethylthiosemicarbazone (HL1) and phenanthrenequinone thiosemicarbazone (HL2), namely [(RuCI)-C-II(L-1)(PPh3)(2)] (1) and [(RuCl)-Cl-II(L-2) (PPh3)(2)] (2), have been synthesised and characterised by IR, UV/Vis and NMR spectroscopy, electrospray mass spectrometry, cyclic voltammetry and X-ray crystallography. In addition, the X-ray crystal structure of [(RuCl2)-Cl-III(L-2)- PPh3]center dot dmso center dot 1.25H(2)O (3 center dot dmso center dot 1.25H(2)O) is reported. The reaction of [(RuCl2)-Cl-II(dmsO)(4)] with HL1 and 1,3,5-triaza-7-phosphaadamantane (PTA) gives the highly water-soluble complex [(RuCl)-Cl-II(L-1)(HPTA)(2)]Cl-2 center dot C2H5OH center dot H2O (4 center dot C2H5OH center dot H2O) (S-25 degrees C - gt = 250 mg/mL), which has been fully characterised. Complex 4 shows strong antiproliferative effects in low micromolar concentrations in the ovarian carcinoma cell line 41M (IC50 = 0.87 mu m) and more moderate activity in the breast cancer cell line SK-BR-3 (IC50 = 39 mu m). The activity of the compound is 6.5- and 5.4-times higher at pH = 6.0 than at pH = 7.4 in the non-small cell lung cancer cell line A549 and the colon carcinoma cell line HT-29 (GI(50) = 24 and 8.0 mu m at pH = 6.0 for A549 and HT-29, respectively).
