Abstract
Four Pd(II) complexes, (dpk)PdCl2 (complex-1), and (dpk)Pd(OAc)2 (complex-2) have been prepared using di(2-pyridyl) ketone as the chelate ligand (dpk). The (dpk·EtOH)PdCl2 (complex-3) and (dpk·EtOH)Pd(OAc)2 (complex-4) were synthesized by selectively introducing complex-1 and complex-2 to an EtOH in situ nucleophilic addition reaction on the O=C of the dpk ligand, respectively. All complexes were characterized using CHN-EA, UV-vis, FT-IR, FAB-MS, EDX, TGA, and NMR physicochemical tools. The XRD-crystallography technique was employed to ascertain the structure of complex-3. The analysis revealed a monoclinic/P21/c crystal system characterized by a square planar structure oriented in the cis direction around the Pd center. Several C-H···Cl and O-H···O H-bonds constructing 2D-S12 and S7 synthons were confirmed via XRD/HSA interactions. The influence of EtOH addition to the O=C group of dpk in (dpk)PdCl2 was documented by using UV-vis/FT-IR spectra and TGA analysis. As catalysts, all complexes have demonstrated a notable catalytic function in the Heck reaction, resulting in a high yield under gentle conditions using iodobenzene and methyl acrylate as model reactions. Moreover, the complex-1 and complex-3 docking activity was evaluated against 1BNA-DNA.

Abstract
This work deals with two new molecule-based materials, namely NiII-complexes of general formulae [Ni(L1)2] (Ni1) and [Ni(L2)2] (Ni2), where L1 = trans-cinnamaldehyde-N(4)-methyl thiosemicarbazone and L2 = trans-cinnamaldehyde-N(4)-ethyl thiosemicarbazone, as potential antitumor agents. Both compounds were characterized by elemental analysis, molar conductivity and spectroscopic techniques (FTIR and NMR). Their molecular structures were obtained by single-crystal X-ray diffraction analysis. Each one crystallizes in a monoclinic space group P 21/c, also the asymmetric unit comprises of one NiII ion located on an inversion centre and one anionic ligand, which acts as a κ2N,S-donor affording a five-membered metallaring. The compounds were screened against two selected tumour cell lines (MCF-7 and A549) and non-tumour fibroblasts cell line (MRC-5) via MTT assays. In both tumour cells, all compounds exhibited higher cytotoxicity than the control drug (cisplatin). The IC50 values ranges of 3.70 - 41.37 μM and 1.06 - 14.91 μM were found for MCF-7 and A549, respectively. Importantly, all of them were less toxicity than cisplatin in MRC-5 with SI values ranged at 11.80 - 86.60. The red blood cell (RBC) assay revealed Ni2 as non-toxic due to its reduced haemolytic effect (0--9% at 1--10 μM). The DNA binding was investigated through a combination of spectrophotometric absorption and emission titrations, electrophoresis, and circular dichroism experiments. As a result, these metal complexes were not able to strongly binding to DNA (Kb values ~104 mol L--1) but suggesting groove-binding interactions. The scavenging ability of them towards 2,2-diphenyl-1-picrylhydrazyl (DPPH) free-radical was also evaluated in this work, but no important antioxidant behaviour was detected. Further, the interaction of Ni1 and Ni2 to human serum albumin (HSA) was explored by quenching of tryptophan emission, warfarin competitive assay, and molecular docking protocols. The HSA binding analyses indicated good affinity of both complexes to Sudlow site I (Kb values ⁓103 mol L-1).

Abstract
Bridge splitting reactions between [Pd(C2,N-dmba)(μ-X)]2 (dmba = N,N-dimethylbenzylamine; X = Cl, I, N3, NCO) and 2,6-lutidine (lut) in the 1:2 molar ratio at room temperature afforded cyclopalladated compounds of general formulae [Pd(C2,N-dmba)(X)(lut)] {X = Cl- (1), I-(2), NNN-(3), NCO-(4)}, which were characterized by elemental analyses and infrared (IR), 1H NMR spectroscopy. The molecular structures of all synthesized palladacycles have been solved by single-crystal X-ray crystallography. The cytotoxicity of the cyclopalladated compounds has been evaluated against a panel of murine {mammary carcinoma (4T1) and melanoma (B16F10-Nex2)} and human {melanoma (A2058, SK-MEL-110 and SK-MEL-5) tumor cell lines. All complexes were about 10 to 100-fold more active than cisplatin, depending on the tested tumor cell line. For comparison purposes, the cytotoxic effects of 1-4 towards human lung fibroblasts (MRC-5) have also been tested. The late apoptosis-inducing properties of 1-4 compounds in SK-MEL-5 cells were verified 24 h incubation using annexin V-Fluorescein isothiocyanate (FITC)/propidium iodide (PI). The binding properties of the model compound 1 on human serum albumin (HSA) and calf thymus DNA (ct-DNA) have been studied using circular dichroism and fluorescence spectroscopy. Docking simulations have been carried out to gain more information about the interaction of the palladacycle and HSA. The ability of compounds 1-4 to inhibit the activity of cathepsin B and L has also been investigated in this work.
