    ABSTRACT: Four new cationic Pd(II) and Pt(II) 5,5-diethylbarbiturate (barb) complexes, [M(barb)(bpma)]X•H2O [M = PdII, X = Cl (1); M = PtII, X = NO3− (2)] and [M(barb)(terpy)]NO3•0.5H2O [M = PdII (3); M = PtII (4)], where bpma = bis(2-pyridylmethyl)amine and terpy = terpyridine, were synthesized and characterized by elemental analysis, IR, UV−vis, NMR, ESI-MS and X-ray crystallography. The DNA binding properties of the cationic complexes were investigated by spectroscopic titrations, displacement experiments, viscosity, DNA melting and electrophoresis measurements. The results revealed that the complexes effectively bind to FS-DNA (fish sperm DNA) via intercalative/minor groove binding modes with intrinsic binding constants (Kb) in the range of 0.50 × 104–1.67 × 105 M−1. Absorption, emission and synchronous fluorescence measurements showed strong association of the complexes with protein (BSA) through a static mechanism. The mode of interaction of complexes towards DNA and protein was also supported by molecular docking. Complexes 1 and 3 showed significant nuclear uptake in HT-29 cells. In addition, 1 and 3 showed higher inhibition than cisplatin on the growth of MCF-7 and HT-29 cells and induced apoptosis on these cells much more effectively than the rest of the complexes as evidenced by pyknotic nuclear morphology. The levels of caspase-cleaved cytokeratin 18 (M30 antigen) in HT-29 cells treated with 1 and 3 increased in a dose-dependent manner, suggesting apoptosis. Moreover, qRT-PCR experiments showed that 1 and 3 caused significant increases in the expression of TNFRSF10B in HT-29 cells, indicating the initiation of apoptosis via cell surface death receptors.

    ABSTRACT: A series of new 3d metal complexes with 5-chloro-quinolin-8-ol (ClQ), [Mn(ClQ)2] (1), [Fe(ClQ)3] (2), [Co(ClQ)2(H2O)2] (3), [Ni(ClQ)2(H2O)2] (4), [Cu(ClQ)2] (5), [Zn(ClQ)2(H2O)2] (6), [Mn(ClQ)3]·DMF (7) and [Co(ClQ)3]·DMF·(EtOH)0.35 (8) (DMF = N,N-dimethylformamide), has been synthesized and characterized by elemental analysis, IR spectroscopy and TG-DTA thermal analysis. X-ray structure analysis of 7 and 8 revealed that these molecular complexes contain three chelate ClQ molecules coordinated to the central atoms in a deformed octahedral geometry and free space between the complex units is filled by solvated DMF and ethanol molecules. Antimicrobial activity of 1 – 6 was tested by determining the minimum inhibitory concentration and minimum microbicidal concentration against 12 strains of bacteria and 5 strains of fungi. The intensity of antimicrobial action varies depending on the group of microorganism and can be sorted: 1 > ClQ > 6 > 3/4 > 2 > 5. Complexes 1 – 6 exhibit high cytotoxic activity against MDA-MB, HCT-116 and A549 cancer cell lines. Among them, complex 2 is significantly more cytotoxic against MDA-MB cells than cisplatin at all tested concentrations and is not cytotoxic against control mesenchymal stem cells indicating that this complex seems to be a good candidate for future pharmacological evaluation. Interaction of 1 – 6 with DNA was investigated using UV-VIS spectroscopy, fluorescence spectroscopy and agarose gel electrophoresis. The binding studies indicate that 1 – 6 can interact with CT-DNA through intercalation, complex 2 has the highest binding affinity. Moreover, complexes 1 – 6 inhibit the catalytic activity of topoisomerase I.

    ABSTRACT: Organometallic complexes have the potential to behave as catalytic drugs. We investigate here Rh(III) complexes of general formula [(Cpx)Rh(N,N′)(Cl)], where N,N′ is ethylenediamine (en), 2,2′-bipyridine (bpy), phenanthroline (phen) or N-(2-aminoethyl)-4-(trifluoromethyl)benzenesulfonamide (TfEn), and Cpx is pentamethylcyclopentadienyl (Cp*), 1-phenyl-2,3,4,5-tetramethylcyclopentadienyl (CpxPh) or 1-biphenyl-2,3,4,5-tetramethyl cyclopentadienyl (CpxPhPh). These complexes can reduce NAD+ to NADH using formate as an hydride source under biologically-relevant conditions. The catalytic activity decreased in the order of N,N-chelated ligand bpy>phen > en with Cp* as the η5-donor. The en complexes (1–3) became more active with extension to the CpX ring, whereas the activity of the phen (7–9) and bpy (4–6) compounds decreased. Cp*Rh(bpy)Cl]+ (4) showed the highest catalytic activity, with a TOF of 37.4±2h−1. Fast hydrolysis of the chlorido complexes 1–10 was observed by 1H NMR (< 10min at 310K). The pKa* values for the aqua adducts were determined to be ca. 8–10. Complexes 1–9 also catalysed the reduction of pyruvate to lactate using formate as the hydride donor. The efficiency of the transfer hydrogenation reactions was highly dependent on the nature of the chelating ligand and the Cpx ring. Competition reactions between NAD+ and pyruvate for reduction by formate catalysed by 4 showed a preference for reduction of NAD+. The antiproliferative activity of complex 3 towards A2780 human ovarian cancer cells increased by up to 50% when administered in combination with non-toxic doses of formate, suggesting that transfer hydrogenation can induce reductive stress in cancer cells.

    ABSTRACT: [Ru(η6-p-cym)Cl{dpa(CH2)4COOEt}][PF6] (cym = cymene; dpa = 2,2’-dipyridylamine; complex 2) was prepared and characterized by elemental analysis, IR and multinuclear NMR spectroscopy, as well as ESI-MS and X-ray structural analysis. The structural analog without a side chain [Ru(η6-p-cym)Cl(dpa)][PF6] (1) as well as 2 were investigated in vitro against 518A2, SW480, 8505C, A253 and MCF-7 cell lines. Complex 1 is active against all investigated tumor cell lines while the activity of compound 2 is limited only to caspase 3 deficient MCF-7 breast cancer cells, however, both are less active than cisplatin. As CD4+ Th cells are necessary to trigger all the immune effector mechanisms required to eliminate tumor cells, besides testing the in vitro antitumor activity of 1 and 2, the effect of ruthenium(II) complexes on the cells of the adaptive immune system have also been evaluated. Importantly, complex 1 applied in concentrations which were effective against tumor cells did not affect immune cell viability, nor did exert a general immunosuppressive effect on cytokine production. Thus, beneficial characteristics of 2 might contribute to the overall therapeutic properties of the complex.

    ABSTRACT: Electrogenerated chemiluminescence, ECL, reactions between tris(2,2'-bipyridine)ruthenium(II), [Ru(bpy)3](2+), and PAMAM GX.0 (X=1 and 2) dendrimers in an aqueous medium were carried out at pH10 (fully deprotonated dendrimer surface). ECL was detected in the presence of GX.0 dendrimers without addition of any known coreactant. Atomic force microscopy, AFM, measurements for GX.0 dendrimers in the presence of the [Ru(bpy)3](2+) complex were also done. AFM images showed the existence of aggregates (pillars) of globular shape, as well as interdendrimer networks forming fibers in the x-y direction for dendrimer aqueous solutions. ECL and AFM results in cooperation suggest that the coreactant effect of the end amine groups is improved by both the dendritic branched shells and the globular z-type aggregates. The ECL efficiency trends as a function of [GX.0] (whole range) can be interpreted taking into account the coreactant effect modulated by the presence of the z and x-y type aggregates. Importantly, ECL efficiency values can be taken as a measure of the change induced on the dendrimer aggregation in aqueous solutions when their concentrations rise. Redox potentials of the [Ru(bpy)3](3+/2+) couple in the presence of the G1.0 and G2.0 dendrimers were also determined. Copyright © 2015 Elsevier Inc. All rights reserved.
