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.

Catalytic activity of Pd dithiolate complexes with large-bite-angle diphosphines in Heck coupling reactions

Palladium(II) complexes of aryl dithiolates and wide-bite-angle diphosphines Xantphos and dppf have been developed as efficient catalysts in Suzuki and Suzuki carbonylation reactions. The catalytic activity of these highly stable, discrete and charged complexes was investigated in Heck coupling reactions of styrene and a variety of aryl bromides. Under optimized reaction conditions these palladium complexes showed excellent activity with high turnover number (6 x 10(6)) and high turnover frequency (4 x 10(5) h(-1)). The effect of bite angle of diphosphines on the catalytic activity of the complexes [Pd-2((PP)-P-boolean AND)(2)(SC12H8S)](2)(OTf)(4) followed the trend (PP)-P-boolean AND = Xantphos > dppf > dppe as the order of their bite angles. The catalyst could be reused, and after three cycles the formation of significant amount of Pd nanoparticles was noticed, which were characterized using powder X-ray diffraction, energy-dispersive X-ray analysis and transmission electron microscopy. The high catalytic activity has been attributed to the Pd nanoparticles.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 685-87-0. Category: bromides-buliding-blocks.

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.

Effect of molybdenum content on the morphology and electronic characteristics of Pd-MoOx nanomaterials and activity evaluation for ethylene glycol electro-oxidation

In this work, Pd-MoOx nanomaterials were developed changing the Mo/Pd precursor ratio and tested for ethylene glycol electro-oxidation reaction (EGOR) in alkaline medium. Mo atomic % compositions of 0, 15, 35, 45 and 75 at. % were evaluated. The increase of Mo at. % resulted in morphology changes due to the directing effect of hexadecyltrimethylammonium bromide (CTAB) on molybdenum passing from hemispheres to nanobelts + hemispheres (15 at. % Mo denoted as Pd85Mo15), then only nanobelts (35 at. % Mo, Pd65Mo35), and nanosheets (45 at. % Mo, Pd55Mo45), and hemispheres were newly obtained at the higher Mo concentration (75 at. % Mo, Pd25Mo75). The activity evaluation of EGOR at 60 degrees C indicated that Pd25Mo75 supported on Vulcan carbon (Pd25Mo75/C) displayed the highest current density (63.80 mA cm(-2)), and according with X-ray photoelectron spectroscopy (XPS) the highest activity of Pd25Mo75/C can be related to the abundance of Mo5+ species, which have oxygen vacancies with a single positive charge. Additionally, the analysis of O 1s core-level corroborated the abundance of oxygen with high number of defects sites. Thereby, it was found that Pd loading can be decreased without comprising the activity by increasing oxygen vacancies of MoOx as co-catalyst.

Measurement and Modeling of Solubility of Galactose in Aqueous Ionic Liquids, 1-Butyl-3-Methyl Imidazolium Bromide, 1-Hexyl-3-Methyl Imidazolium Bromide and 1-Butyl-3-Methylimidazolium Chloride at T = (298.15 And 308.15) K

Background: Saccharides are considered as abundant, cheap and renewable starting materials for chemicals and fuels. Recently, ionic liquids have been used as green solvents for saccharides. The solubility values of galactose in aqueous ionic liquid solutions are not available. Thus, the main objective of this research was to determine the solubility of galactose in aqueous solutions containing ionic liquids, 1-butyl-3-methyl imidazoliwn bromide, [BMIm]Br, 1-butyl-3-methylimidazolium chloride [BMIm]Cl and 1-hexyl-3-methyl imidazolium bromide, [HMIm]Br at different mole fractions of ionic liquids at T = (298.15 and 308.15) K. Methods: In this study, the gravimetric method was used to measure the solubility of galactose in aqueous ionic liquids solutions. Results: The solubility values of galactose in water and aqueous ionic liquid solutions were correlated with the activity coefficient models of Wilson, NRTL, modified NRTL, NRF-NRTL, and UNIQUAC. Conclusion: It was concluded that with increasing the mole fraction of ionic liquids, the solubility values of galactose decrease and in fact all of these ionic liquids show saltingout effect on aqueous galactose solutions and this behavior is stronger in ionic liquid 1-butyl-3-methylimidazolium chloride.

Die Reaktion zwischen Iodid- und Iodat-Ionen – ein lange wahrendes kinetisches ProblemThe reaction between iodide and iodate ions – a long lasting kinetic problem

The bromid-bromate-reaction in acidic aqueous solutions was a widely introduced reaction in high school and undergraduate level chemistry. Because of the supposed cancerogenous properties of potasium bromide experiments are not allowed with this substance in high schools. In this article the reaction between iodide and iodate in the presence of acids was investigated. Under certain conditions we obtained a pentamoleculare law of reaction rate.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 108-85-0, in my other articles.

Behaviour of Human Oral Epithelial Cells Grown on Invisalign(R) SmartTrack(R) Material

Invisalign aligners have been widely used to correct malocclusions, but their effect on oral cells is poorly known. Previous research evaluated the impact of aligners’ eluates on various cells, but the cell behavior in direct contact with aligners is not yet studied. In the present study, we seeded oral epithelial cells (cell line Ca9-22) directly on Invisalign SmartTrack material. This material is composed of polyurethane and co-polyester and exhibit better mechanical characteristics compared to the predecessor. Cell morphology and behavior were investigated by scanning electron microscopy and an optical cell moves analyzer. The effect of aligners on cell proliferation/viability was assessed by cell-counting kit (CCK)-8 and 3,4,5-dimethylthiazol-2-yl-2,5-diphenyl tetrazolium bromide (MTT) assay and live/dead staining. The expression of inflammatory markers and proteins involved in epithelial barrier function was measured by qPCR. Cells formed cluster-like structures on aligners. The proliferation/viability of cells growing on aligners was significantly lower (p < 0.05) compared to those growing on tissue culture plastic (TCP). Live/dead staining revealed a rare occurrence of dead cells on aligners. The gene expression level of all inflammatory markers in cells grown on aligners' surfaces was significantly increased (p < 0.05) compared to cells grown on TCP after two days. Gene expression levels of the proteins involved in barrier function significantly increased (p < 0.05) on aligners' surfaces after two and seven days of culture. Aligners' material exhibits no cytotoxic effect on oral epithelial cells, but alters their behavior and the expression of proteins involved in the inflammatory response, and barrier function. The clinical relevance of these effects has still to be established. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

In-depth Investigation of Hg2Br2 Crystal Growth and Evolution

Physical vapor transport (PVT) has frequently been adopted for the synthesis of mercurous bromide (Hg2Br2) single crystals for acousto-optic modulators. However, thus far, very few in-depth studies have been conducted that elucidate the growth process of the Hg2Br2 single crystal. This paper reports an in-depth investigation regarding the crystal growth and evolution behavior of the Hg2Br2 crystal with facet growth mode. Based on the experimental and simulation results, the temperature profile conditions concerning the seed generation and seed growth could be optimized. Next, the PVT-grown Hg2Br2 crystals (divided into single crystal and quasi-single crystal regions) were characterized using various analysis techniques. The single-crystal Hg2Br2 was found to possess a more uniform strain than that of the quasi-single crystal through a comparison of the X-ray diffraction data. Meanwhile, the binding energy states and electron backscatter diffraction images of the as-synthesized Hg2Br2 crystals were similar, regardless of the crystal type. Furthermore, Raman spectroscopy and transmission electron microscopy analyses provided information on the atomic vibration mode and atomic structures of the two kinds of samples. The synergistic combination of the simulation and experimental results used to verify the growth mechanism facilitates the synthesis of high-quality Hg2Br2 crystals for potential acousto-optic tunable filter device applications.

Recent Advances and Uses of (Me4N)XCF3 (X=S, Se) in the Synthesis of Trifluoromethylthiolated and Trifluoromethylselenolated Compounds

The introduction of trifluoromethylthio (SCF3) and trifluoromethylseleno (SeCF3) substituents into organic molecules significantly improves the electron-withdrawing and lipophilic properties of their parent compounds. Therefore, a vast class of versatile reagents were employed to access the corresponding fluorine-containing compounds. Among them, tetramethylammonium salts, such as (Me4N)SCF3 and (Me4N)SeCF3, have been employed as practical and efficient non-metal reagents for developing efficient trifluoromethylthiolation and trifluoromethylselenolation in recent years. This Minireview systematically illustrates the application of (Me4N)XCF3 (X=S, Se) in the synthesis of trifluoromethylthiolated and trifluoromethylselenolated compounds, and its content is divided into two categories: transition-metal-catalyzed reactions, and transition-metal-free reactions.

Comparison of coagulative colloidal microbubbles with monomeric and polymeric inorganic coagulants for tertiary treatment of distillery wastewater

The flotation using coagulative colloidal gas aphrons (CCGAs) is of great potential in effectively removing the recalcitrant dissolved organic matter (DOM) and colorants from the bio-chemically treated cassava distillery wastewater. As bubble modifier, the monomeric and polymeric inorganic coagulants need to be studied considering their distinct influence on the surfactant/coagulant complex, the properties of colloidal aphrons as well as the process performance and mechanisms. Such studies help to create robust CCGAs with high flotation potential. In this work, the commonly-used monomeric and polymeric Al(III)- and Fe(III)-coagulants were combined with the cationic surfactant – cetyl trimethylammonium bromide (CTAB) to generate CCGAs. The CCGAs functionalized with Al(III)-coagulants (both monomeric and polymeric ones) were featured as small bubble size, strong stability and high air content. Particularly, the monomeric Al(III)-coagulant (AlCl3 in this work) resulted in low surface tension and high foamability when being mixed with CTAB in the bubble generation solution. Those CCGAs achieved high removal efficiencies of DOM and colorants at low coagulant concentrations. The molecular weight of DOM in effluent was well controlled below 1 kDa by CCGAs. For the flocs obtained from CCGA-flotation, the characteristic Raman band of DOM and colorants showed the layer-by-layer variation of Raman intensity which decreased from the outer layer to the center. In contrast with the conventional coagulation-flotation, the reduction of coagulant dosage by CCGAs was 67% (AlCl3), 25% (polyaluminum chloride), 60% (Fe-2(SO4)(3)) and 40% (polyferric sulfate). The sludge production could then be largely reduced, and meanwhile, the retention time was shortened by 9.5 min. (C) 2019 Elsevier B.V. All rights reserved.
