Abstract
Five newly synthesized copper(II) 5-fluorouracil (5-FU) complexes of polypyridyl co-ligands with good solubility in water, namely [CuCl(5-FU)(bpy)(DMSO)] (1), [Cu(5-FU)(phen)2](5-FU)·4H2O (2), [Cu(5-FU)(dpya)2](NO3)·2.5H2O (3), [Cu(5-FU)(NO3)(bpyma)]·H2O (4) and [CuCl(5-FU)(terpy)] (5) (bpy = 2,2'-bipyridine, phen = 1,10-phenanthroline, dpya = 2,2'-dipyridylamine, bpyma = bis(2-pyridylmethyl)amine and terpy = 2,2';6',2''-terpyridine), were characterized by elemental analysis and a number of spectrometric methods. The structures of complexes 1-5 were determined by X-ray crystallography and the copper(II) ions were five coordinate. Cytotoxic activity of the complexes in four human cancer cell lines, A549 (lung carcinoma), MDA-MB-231 (breast carcinoma), HCT116 (colon carcinoma) and DU145 (prostate carcinoma), and a normal cell line, BEAS-2B (human lung epithelial), was determined by SRB assay and compared with that of 5-FU and cisplatin. The complexation of 5-FU together with polypyridyl ligands resulted in a significant increase in the cytotoxicity of the complexes, with complex 2 exhibiting the highest anticancer potency against all the cell lines, with HCT116 being the most sensitive. The mode of action of cell death for 2 was investigated using morphological imaging and cytometric analyses, including the capacity for induction of apoptosis, generation of reactive oxygen species, mitochondrial dysfunction and DNA damage.

Abstract
A series of novel Zn(II) complexes of 5-fluorouracilate (5-FU), namely [Zn(5-FU)2(bpy)] (1), [Zn(5-FU)2(phen)] (2), [Zn(5-FU)2(dpya)]·H2O (3), [Zn(5-FU)2(bpyma)]·2H2O (4) and [Zn(5-FU)2(terpy)]·H2O (5), were synthesized and structurally characterized by spectroscopic methods and X-ray crystallography. 5-FU was coordinated to Zn(II) via the deprotonated N3 site and also presented the N1 and N3 linkage isomerism in 4 and 5 due to its tautomerism. The antiproliferative activity of the complexes was studied against lung (A549), breast (MDA-MB-231), colon (HCT116) and prostate (DU145) cancer cell lines. Complexes 1, 4 and 5 except 2 and 3 showed potent growth inhibitory activity towards selected cancer cells. Remarkably, 4 was highly cytotoxic towards A549 and MDA-MB-231 cell lines, being more active than the clinical drugs cisplatin and 5-FU. In addition, 4 was not toxic to normal lung cells (BEAS-2B). The complex exhibited a significantly high affinity towards DNA as assessed by gel electrophoresis and DNA docking. The mechanistic studies of 4 in A549 cells indicated that the complex induced apoptotic cell death as evidenced via caspase 3/7 activity, Bcl2 inactivation, annexin V and DAPI/PI staining. 4 further elevated the levels of reactive oxygen species (ROS), depolarized mitochondria and enhanced the expression of γ-H2AX, thus contributing to its remarkable anticancer activity.

Abstract
New Zn(ii), Cd(ii) and Hg(ii) complexes of saccharinate (sac) and 2,6-bis(2-benzimidazolyl)pyridine (bzimpy), [Zn(bzimpy)2](sac)2·2H2O (Zn), [Cd(sac)2(bzimpy)] (Cd) and [Hg(sac)2(bzimpy)] (Hg), were prepared and fully characterized by spectroscopic methods and X-ray crystallography. In vitro anticancer screening in A549 (lung), MCF-7 (breast) and HT29 (colon) cell lines showed that Zn was highly cytotoxic against A549 and MCF-7 cells with IC50 values of 1.74 ± 0.06 and 3.15 ± 0.10 μM, respectively, and Hg demonstrated potent cytotoxic activity in MCF-7 cells (8.61 ± 0.98 μM), while Cd and bzimpy exhibited moderate growth inhibitory activities in all of the cell lines. In addition, they showed significantly lower toxicity towards normal human breast epithelial MCF10A cells. Moreover, the complexes exhibited significantly high nuclease activity towards plasmid DNA and their interactions with DNA were assessed by gel electrophoresis and DNA docking. Zn and Hg induced G0/G1 cell arrest and apoptotic cell death detected via typical DNA condensation/fragmentation, annexin V staining and caspase 3/7 activity in A549 and MCF-7 cells. These complexes further caused depolarization of mitochondria and oxidative damage of genomic DNA following excessive production of reactive oxygen species (ROS).

Abstract
New neutral [M(sac)2(diphos)] and cationic [M(diphos)2](sac)2 complexes, where M = PdII or PtII, sac = saccharinate, and diphos = 1,1-bis(diphenylphosphino)methane (dppm) or 1,2-bis(diphenylphosphino)ethane (dppe), were synthesized and structurally characterized. The anticancer activity of the complexes was investigated against MCF-7 (breast), A549 (lung), HCT116 (colon), DU145 (prostate) cancer and BEAS-2B (normal bronchial epithelial) cells. Neutral Pt-dppm (2) and Pd-dppe complexes (5) did not show any biological activity. The cationic Pd-dppe (7) complex displayed antiproliferative activity, while the rest of the complexes exhibited potent cytotoxicity compared with cisplatin. The active Pd(ii)/Pt(ii) complexes were then included in further studies including interaction with DNA/HSA, nuclease activity, cellular uptake and lipophilicity. The potent complexes induced the apoptotic cell death as probed through annexin V positivity and caspase activation. Mechanistic studies on HCT116 cells showed that the complexes cause cell cycle arrest at the DNA synthesis (S) phase and excessive generation of reactive oxygen species (ROS), damaging to both mitochondria and DNA.

Abstract
A new imineoxime compound {(1E,2E)-(2-hydroxy-ethylimino)-naphthalene-2yl-ethanal oxime (heineoH)} and its palladium(II) and platinum(II) complexes ([M(heineo)2]) have been synthesized and characterized by IR, NMR, UV-vis, elemental analysis, mass spectra and X-ray single crystal diffraction. [Pt(heineo)2] was obtained as a single crystal, while [Pd(heineo)2] was synthesized as a polycrystalline powder. The X-ray diffraction analysis of the [Pt(heineo)2] indicated that the platinum(II) ion is coordinated by two heineo ligands in a distorted square-planar geometry. DFT (B3LYP/6-311++G(d,p) and LANL2DZ) calculations on the ligand and its complexes were carried out to correlate the geometry and vibrational and electronic properties. Additionally, heineoH is fluorescent in EtOH at room temperature, but the fluorescence is quenched in the case of the metal complexes.

Abstract
A new palladium(II) complex, [Pd(ppeieo)(inap)]·DMSO (ppeieo=(1E,2E)-phenyl-[(1-phenylethyl)imino]-ethanal oxime and inap=isonitrosoacetophenone) has been synthesized and characterized by elemental analysis, UV-vis, IR, NMR. X-ray diffraction analysis of the DMSO solvate of the complex shows that the palladium(II) ion is coordinated in a distorted square-planar geometry by ppeieo and inap, which is formed during the hydrolysis of ppeieo. DFT (B3LYP/LANL2DZ) calculations on the complex have been carried out to correlate geometry and spectroscopic properties such as electronic, vibrational and NMR chemical shifts. The complete vibrational frequency assignments were made and the calculation results were applied to simulate infrared spectra of the title compound which shows good agreement with observed spectra. The calculated HOMO and LUMO energies show that several transitions including the π→π(*) and charge transfer occur within the molecule. The chemical shifts reasonably correspond to the calculated spectra.
