Abstract
A family of cationic cycloplatinated(II) complexes [Pt(dfppy)(P^P)]Cl, dfppy = 2-(2,4-difluorophenyl)pyridine, incorporating bisphosphine ligands, P^P = bis(diphenylphosphino)methane (1, dppm), 1,2-bis(diphenylphosphino)ethane (2, dppe) and 1,2-bis(diphenylphosphino)benzene (3, dppbz), was prepared. The complexes were characterized by means of several analytical and spectroscopic methods. These complexes displayed acceptable stability in the biological environments which was confirmed by NMR, HR ESI-MS and UV-vis techniques. The antiproliferative properties of these complexes were evaluated by National Cancer Institute (NCI) at National Institutes of Health (NIH) against 60 different human tumor cell lines such as leukemia, melanoma, lung, colon, brain, ovary, breast, prostate and kidney. These complexes showed higher cytotoxicity than cisplatin against a wide variety of cancer cell lines such as K-562 (leukemia), HOP-92 (lung), HCT-116 (colon), OVCAR-8 (ovarian), PC-3 (prostate), MDA-MB-468 (breast), and melanoma cancer cell lines. Complex 3 as the most potent compound in this study furnished an excellent anti-proliferative activity compared to the cisplatin against Hela, SKOV3, and MCF-7 cancer cell lines. The main mode of the interaction of 1-3 with DNA was also determined using molecular docking studies.

Abstract
In this article, we have reported the preparation and structural characterization of a new Schiff base ligand (E)-2-(((2,6-difluorophenyl)imino)methyl)phenol (HSBL) and its derived metal(II) complexes [Cu(SBL)2] (1), [Ni(SBL)2] (2) and [Pd(SBL)2] (3). Using various analytical and spectroscopic techniques, their structural properties have been appraised. The proposed chemical structure of HSBL has been confirmed by Single crystal XRD studies. Bidentate characteristic of HSBL and its coordination with metal(II) ions through the oxygen atom of the phenolic group and nitrogen atom of the azomethine group have been evaluated from the FT-IR spectral analysis. Pd(II) complex of HSBL (complex 3) has found to be efficient in bringing about the interaction with DNA as well as BSA molecules. The in vitro antimicrobial studies have been demonstrated that complex 3 has a superior antimicrobial activity than HSBL, complexes 1 and 2. According to the values of zone of inhibition, the antimicrobial ability has been increased in the order of 3 > 1 > 2 > HSBL. A significant decrease in percent cell viability has been suggested that complex 3 has remarkable cytotoxicity (IC50 = 15.7 ± 0.6 μg/mL) on human breast cancer (MCF-7) cells. Besides, their induced apoptosis pathway of cytotoxicity has been demonstrated by fluorescence staining techniques using AO/EB staining method. We hope this article will be very helpful for future research on the development of new anticancer agents.

Abstract
Three tetranuclear (1-3) complexes and a mononuclear (4) palladium(ii) complex were synthesized from 3-acetyl-chromen-2-one Schiff base ligands [H2-3MAC-Rtsc] (where R = H [H2-3MAC-tsc]; CH3[H2-3MAC-mtsc]; C2H5[H2-3MAC-etsc] or C6H5[H2-3MAC-ptsc]) and potassium tetrachloropalladate. Their formation was confirmed by spectroscopic techniques and X-ray crystallographic analysis. Their ability to bind with DNA and albumin was analysed by using absorption and emission titrations. The MTT assay was carried out to analyze the anticancer potential of the ligands and synthesized complexes against HepG2 (human liver cancer) and HT-29 (human colon cancer) cells. In addition, the compounds were less toxic when tested against the human normal keratinocyte cells (HaCaT). Ligands and complexes displayed better cytotoxicity with lower IC50 values than the standard drug cisplatin. Further AO-EB and DAPI staining assays were carried out to detect the mode of cell death induced by the complexes i.e. apoptosis or necrosis. The complex 3 showed better cytotoxicity and was further subjected to flow cytometric analysis. The results suggested that the complex 3 induced apoptotic cell death.

Abstract
Herein, a robust docking protocol was developed by using a low-cost workflow to highlight the modulation at ATPase domain from Human Topoisomerase-IIα (TOP2A) towards four novel Pd(II)-complexes bearing N,S-donor ligands. In vitro TOP2A inhibition assay confirmed the ability of them to prevent the enzyme functions into concentration ranging at 6.25-25μM. These results exhibited more effectivity than anticancer agent etoposide (35μM) and merbarone (40-50μM). The compounds were screened via Resazurin assay against MCF-7, MDA-MB-231 (Human breast), DU-145 (Human prostate), A549 (Human lung) and Cal27 (Human tongue) tumor cell lines revealing great cytotoxic effects, primarily to MCF-7 (IC50=1.81-4.46μM). As well, 1-4 exhibited their selectivity index (SI) higher than cisplatin against HEK-293 (human kidney) normal cells, at least 11.6-fold (SI1-4=1.4-5.0; SIcis=0.12). Further, Red Blood Cell hemolytic test suggested in vitro non-toxic character for compound 4, previously evaluated as the most effective TOP2A inhibitor.

Abstract
The title NiII complex, Ni(L)(LH2) (1), where LH2 is S-2-methybenzyl-β-N-(2-hydroxy-3-methoxybenzylmethylene) dithiocarbazate, was isolated from the reaction of Ni(acetate)2·4H2O and two molar equivalents of LH2. The complex was characterized by elemental analysis, spectroscopy (IR and UV) as well as by a single-crystal X-ray structure determination. The nickel(II) center is coordinated within a cis-NOS2 donor set that defines a square planar geometry. Three donor atoms, i.e., N, O, and S, are provided by a doubly deprotonated S-2-methybenzyl-β-N-(2-hydroxy-3-methoxybenzylmethylene) dithiocarbazate ligand while the fourth donor, i.e., a thione-S, comes from the neutral form of the dithiocarbazate ligand. In the LH2 ligand, an intramolecular hydroxy-O-H…N(imine) hydrogen bond is found. There is also an intra-ligand, charge assisted amine-N-H…O(phenoxide) hydrogen bond. A notable feature of the molecular packing is the formation of supramolecular chains sustained by π…π stacking interactions whereby the interacting rings are the five- and six-membered chelate and methoxybenzene rings. The chains are connected into a three-dimensional architecture by methyl-C-H…O(methoxy), methoxy-C-H…S(ester), and tolyl-C-H…π(tolyl) interactions.

Abstract
The synthesis of three new cyclometallated platinum(ii) compounds containing a para-tolyl ligand and a tridentate [C,N,N'] (cm1) or a bidentate [C,N] ligand and an additional ligand such as SEt2 (cm2) or PPh3 (cm3) is reported. The X-ray molecular structure of platinum(ii) compound cm3 is also presented. Intermolecular oxidative addition of methyl iodide or iodine upon cm1, cm2 and cm3 produced six novel cyclometallated platinum(iv) compounds. The cytotoxic activity against a panel of human adenocarcinoma cell lines (A-549 lung, MDA-MB-231 and MCF-7 breast, and HCT-116 colon), DNA interaction, topoisomerase I, IIα, and cathepsin B inhibition, and cell cycle arrest, apoptosis and ROS generation of the investigated complexes are presented. The best results for antiproliferative activity were obtained for platinum(iv) compounds cm1MeI and cm1I2 arising from oxidative addition of methyl iodide and iodine, respectively, to cm1. Cyclometallated platinum(iv) compounds cm1MeI and cm3MeI induce significant changes in the mobility of DNA and, in addition, cm1MeI, cm3MeI and cm1I2, showed considerable topoisomerase IIα inhibitory activity. Moreover, the compounds exhibiting the higher antiproliferative activity (cm1MeI and cm1I2) were found to generate ROS and to supress HCT-116 colon cancer cell growth by a mixture of cell cycle arrest and apoptosis induction. 1H NMR experiments carried out in a buffered aqueous medium (pH 7.40) indicate that compound cm1MeI is not reduced by common biologically relevant reducing agents such as ascorbic acid, glutathione or cysteine.

Abstract
The development of transition-metal-based antitumor drug candidates increases the metallopharmaceuticals study dramatically. Two trans-thiosemicarbazone-based, Schiff base palladium (Pd) (II) complexes, DMABTSPd (TSPd) and DMABPTSPd (PTSPd), were prepared and characterized as described in our previous study. Here, we investigated whether the two complexes have antitumor effect on human gastric adenocarcinoma cell lines, BGC-823 and SGC-7901, compared with normal human gastric mucosal epithelial cell line, Ges-1. The results show that the Pd complex with the bare amino group (DMABTSPd(TSPd)) can inhibit cell viabilities and induce apoptosis in human gastric carcinoma cells, rather than the Pd complex without the bare amino group (DMABPTSPd (PTSPd)). This occurs via a mitochondrial-related pathway by down-regulating the level of Bcl-2 expression and up-regulating the level of Bid expression. Meanwhile, DMABTSPd (TSPd) suppressed tumor growth via a mitochondrial-related pathway in a nude mouse tumor xenograft model derived from BGC-823 cells. These findings demonstrate that DMABTSPd (TSPd) is worthy of further structural optimization and representing a promising Pd complex for the development of a new antitumor therapeutic agent.
