Synthesis, Structure, and Chemical Nuclease Activity of DNA with [Cu(dpq)(L-Met)Cl] center dot H2O

A new mononuclear copper complex [Cu(dpq)(L-Met)Cl] . H2O has been designed and synthesized using the phenanthroline derivative dipyridoquinoxaline (dpq). This complex has been characterized by element analysis and X-ray single crystal diffraction. The crystal structure of the complex belongs to a monoclinic system with space group C2/c. Binding of the complex to DNA has been investigated by absorption spectroscopy, fluorescence spectroscopy, and agarose gel electrophoresis. Spectrophotometric studies have showed that the mode of binding is intercalation with a binding constant K-b of 1.25 x 10(3) L mol(-1). Additionally, the complex could quench an ethidium bromide-DNA complex. The apparent binding constant value for the complex is 1.89 x 10 (5) L mol(-1), which is slightly lower than the classical binding constant of 10(7) L mol(-1). In addition, the quenching mechanism of the complex has been not static or dynamic. Agarose gel electrophoresis has shown that the complex cleaved circular pBR322 plasmid DNA to both nicked and linear forms; at higher concentrations and longer reaction times, the cutting results have been improved. The cleavage mechanism between the complex and plasmid DNA may involve singlet oxygen and hydroxyl radical as reactive oxygen species.

The first coordination polymers with an [O](2)[N]P(S)-Hg segment: a combined experimental, theoretical and database study

The study of one-dimensional coordination polymers {Hg2Cl4L1}(n) (1), {HgBr2L1}(n) (2) and {Hg2Cl4L2}(n) (3) (L-1 = (S)P(OC2H5)(2)NHC6H4NHP(S)(OC2H5)(2) and L-2 = (S)P(OC2H5)(2)NC4H8NP(S)(OC2H5)(2)) is the first such structural study of Hg(ii) coordination polymers with (O)(2)(N)PS-based ligands. The mercury atoms adopt a distorted trigonal pyramidal environment, Hg(Cl)(3)(S) for 1 and 3 and Hg(Br)(2)(S)(2) for 2, and the difference observed in the stoichiometry of mercury halide to the thiophosphoramide ligand in 1 and 3 with respect to the one in 2 is a result of the formation of the Hg2Cl2 ring, however, the molar ratio 2:1 of HgX2 (X = Cl and Br) to ligand was used for the preparation of all three complexes. The strengths of mercury-sulfur and mercury-halide covalent bonds are evaluated by theoretical calculations (QTAIM and NBO) which show their principally electrostatic nature with a partial covalent contribution. The energies of interactions building supramolecular assemblies and intramolecular interactions, i.e. NHCl, NHBr, CHCl, CHBr, CHO, CHS and CH pi, are theoretically evaluated. The characteristic structural features arising from the aromatic/aliphatic linkers in the ligands and chloride/bromide attached to mercury are investigated by Hirshfeld surface analysis and fingerprint plots.

Apoptotic effect of the anphen sodium antioxidant in combination with H2O2 on Lewis carcinoma cells

It was shown by immunoblotting that the introduction of an antitumor antioxidant, sodium 2-carboxy-2-(N-acetylamino)-3-(3,5-di-tert-butyl-4-hydrophenyl)propanoate (anphen sodium), into a suspension of Lewis carcinoma cells induces a sharp decrease in the contents of the monomer and homodimer of the anti-apoptotic Bcl-2 protein. According to fluorescence analysis, the number of apoptotic cells sharply increased 1 h after exposure to anphen sodium; preliminary addition of 5 mu mol L-1 of hydrogen peroxide increased the cell membrane permeability of anphen sodium and the number of apoptotic cells. The onset of apoptosis detected using fluorophores is comparable in time with the start of the decline of the Bcl-2 level. It was assumed that the mechanism of action of anphen sodium may include the interaction of the agent with the hydrophobic (BH3) domain of Bcl-2 family proteins.

Synthesis of Spherical Nanostructured gamma-Al2O3 Particles using Cetyltrimethylammonium Bromide (CTAB) Reverse Micelle Templating

We demonstrated the synthesis of spherical nanostructured gamma-Al2O3 using reverse micelle templating to enhance the surface area and reactant accessibility. Three different surfactants were used in this study: benzalkonium chloride (BZK), sodium dodecyl sulfate (SDS) and cetyltrimethylammonium bromide (CTAB). We obtained spherical nanostructured particles only using CTAB that form a reverse micelle emulsion. The particles have wide size distribution with an average size of 2.54 mu m. The spherical particles consist of nanoplate crystallites with size 20-40 nm randomly arranged forming intercrystallite spaces. The crystalline phase of as-synthesized and calcined particles was boehmite and gamma-Al2O3, respectively as determined by XRD analysis. Here, the preserved particle morphology during boehmite to gamma-Al2O3 transformation opens a facile route to synthesize gamma-Al2O3 particles with complex morphology. The specific surface area of synthesized particles is 201 m(2)/g, which is around five times higher than the conventional gamma-Al2O3 (Aldrich 544833). Spherical nanostructured gamma-Al2O3 provides wide potential applications in catalysis due to its high density closed packed structure, large surface area, and high accessibility.

Glucose-Derived N-Doped Graphitic Carbon: Facile One-Pot Graphitic Structure-Controlled Chemical Synthesis with Comprehensive Insight into the Controlling Mechanisms

Modification of graphitic structure chemistry and physics affords the N-doped graphitic carbonaceous materials (NGCMs) superior and novel functional properties, which is essential for substantial development of applications based on such materials. The present research provides novel simple structure-controlled chemical synthesis of NGCM. NGCM is grown from cyclic polymerization of glucose molecules upon hydrothermal treatment, employing Cetyltrimethylammonium bromide (CTAB) and ammonia as structure-directing agents. Hydrothermal temperature and CTAB dose were manipulated and the produced graphitic structure has been explored in terms of oxidation state, N-doping, surface functionalization with CTAB and morphology. NGC derivatives of various structural features are obtained. Products range from oxidized graphitic carbon of mixed micro-sized sphere/sheet morphology to highly-reduced graphene-like nanosheets; the C/O atomic ratio increases from 8.2-12.4 and sheet thickness downs from 30 mu m- similar to 1 nm. Also, N-doping configurations and graphitic surface functionalization by CTAB are greatly influenced. CTAB plays the key role in setting the graphitic structure characteristics. Additionally, ammonia has a modest effect. Understanding of the controlling mechanisms is focused. The effective and ease control of graphitic structure via this facile, economic and ecofriendly synthesis approach, can benefit the design of NGCM with tuned functional properties for specific applications in technological industries.

Cytoproliferative and Anti-Oxidant Effects Induced by Tannic Acid in Human Embryonic Kidney (Hek-293) Cells

Tannic acid (TA) portrays a myriad of beneficial properties and has forthwith achieved incessant significance for its cytoprotective qualities in traditional and modern-day medicine. However, TA displays an ambiguous nature demonstrating anti-oxidant and pro-oxidant traits, beckoning further research. Although vast literature on the anti-proliferative effects of TA on cancer cell lines exist, the effects on normal cells remain unchartered. Herein, the cytoproliferative and anti-oxidant effects induced by TA in human embryonic kidney (Hek-293) cells were investigated. Data obtained from the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay demonstrated that TA increased the cell viability and cellular proliferation rate at higher concentrations. Hoechst assay, examining proliferation marker Ki67 supported these findings. DNA fragmentation and oxidative stress-inducers were specifically noted at IC25 and IC50 treatments via biochemical assays. This alluded to TA’s pro-oxidant characteristics. However, the countervailing anti-oxidant defence mechanisms as the endogenous anti-oxidants and phase2 detoxification enzymes were significantly upregulated. Luminometry fortified the anti-oxidant capacity of TA, whereby executioner caspase-3/7 were not activated subservient to the activation of initiator caspases-8 and -9. Thus, proving that TA has anti-apoptotic traits, inter alia. Therefore, TA proved to harbour anti-oxidant, anti-apoptotic, and proliferative effects in Hek-293 cells with its partial cytotoxic responses being outweighed by its cytoprotective mechanisms.

A Cyan Emitting CsPbBr3 Perovskite Quantum Dot Glass with Bi Doping

CsPbBr3:xBi(3+) quantum dot glass was prepared by using traditional melting-quenching and heat treatment processes. The effects of Bi doing on the sinter of the precursor of glass and the crystalline of the perovskite quantum dot were discussed detailly. By doping Bi2O3 into the borosilicate glass matrix, the melting temperature was reduced to 900 degrees C. The tunable emission of CsPbBr3 quantum dots from 523 to 493 nm was achieved with suitable Bi2O3 doping. Due to the protection of the inorganic glass matrix, the prepared CsPbBr3 quantum dots still exhibit excellent thermal stability after multiple thermal cycles and thermal shocks. This provides a good solution to the problem of poor thermal stability of perovskite quantum dots.

Exploring the DNA binding efficacy of Cobalt(II) and Copper(II) complexes of hydroxamic acids and explicating their anti-cancer propensity

Calf-thymus DNA (ct-DNA) binding efficacy of Bis(N-p-tolylbenzohydroxamato)Cobalt(II), [N-p-TBHACo(II)] and Bis(N-p-naphthylbenzohydroxamato)Copper(II), [N-p-NBHA-Cu(II)] have been studied by multi-spectroscopic approaches coupled with viscosity measurements and molecular docking. The binding constants of the complexes towards ct-DNA evaluated are 1.68 +/- 0.03 x 10(5) M-1 and 1.52 +/- 0.07 x 10(5) M-1 for N-p-TBHA-Co(II) and N-p-NBHA-Cu(II), respectively. Stern-Volmer quenching constants were also evaluated from fluorescence measurement. The mode of binding was further disclosed by ethidium bromide and Hoechst 33258 displacement, confirmed by fluorescence measurement, which reveals a groove mode of binding. The three-dimensional fluorescence spectroscopy was also applied to know the interaction between complexes and ct-DNA. The relative viscosity increases with increase in the concentration of the N-p-TBHA-Co(II) and N-p-NBHA-Cu(II) while adding to ct-DNA was also uncovered, but lesser than the ct-DNA alone suggesting groove binding mode. DRS-FTIR analysis, cyclic voltammetry and circular dichroism studies further confirmed a strong interaction between complexes and ct-DNA. The docked posture of ct-DNA with N-p-TBHA-Co(II) and N-p-NBHA-Cu(II) uncover the strong binding interactions which revealed minor groove binding. The in-vitro cytotoxicity studies was carried out by MIT assay for both the complexes against MCF-7 breast cancer cell line. (C) 2019 Elsevier B.V. All rights reserved.
