The design and preparation of porous catalysts with multiple catalytically active sites for synergistically catalytic conversion of CO2 still remains a challenge. Herein, cobalt porphyrin as a Lewis acidic active site was introduced in imidazolium-functionalized cationic covalent triazine frameworks (denoted as Co-PCCTFs) via copolymerization of cobalt 5,10,15,20-tetrakis(4-cyanophenyl)porphyrin (Co-TPPCN) and 1,3-bis(4-cyanophenyl) imidazolium chloride ([BCIM]Cl). The obtained bifunctional Co-PCCTFs with positively charged imidazolium groups have high BET surface areas and show sufficient CO2 adsorption uptakes. The nucleophilic halide anions of the imidazolium parts and the cobalt porphyrin Lewis acid sites were positioned in close proximity so that the Co-PCCTFs could synergistically activate substrates and intermediates. Compared with ICTF-400 free of Co2+ that was obtained from [BCIM]Cl, Co-PCCTF5 exhibited enhanced activity for the cycloaddition of CO2 to epoxides to produce cyclic carbonates without a cocatalyst under mild conditions. Moreover, Co-PCCTF5 is sufficiently stable so that it could be reused more than 5 times without loss of catalytic activity. This work provides a new approach for the design and preparation of efficient multifunctional catalysts with multiple sites for synergistic catalysis.

Contamination of foods with Listeria monocytogenes is a frequent occurrence that results in expensive recalls and on occasion, deadly outbreaks of foodborne listeriosis. Biofilm production is thought to play a key role in the persistence of these bacteria in food processing facilities. To date, research on L. monocytogenes biofilms has predominantly involved pure cultures grown under conditions that do not represent actual food processing environments. In nature, multiple microbial species comprise biofilm communities that develop under constantly changing conditions. This study investigated changes in the characteristics of biofilms harbouring L. monocytogenes (Lm) when in the presence of two different commensal bacteria, Lactobacillus plantarum (Lp) and Pseudomonas fluorescens (Pf), commonly isolated from ready-to-eat (RTE) meat products. Using CDC biofilm reactors, four different strain combinations (Lm monoculture; Lm + Lp; Lm + Pf; and Lm + Lp + Pf) were grown on stainless steel (SS) and high-density-polyethylene (PE-HD) coupons following a dynamic 12-day regimen of simulated meat processing conditions (SMPC) that exposed cells to periods of nutrient cycling and starvation. Viable numbers of L. monocytogenes 568 (Lm568) in pure culture biofilms at the end of the regimen were 5.8 and 6.4 log(10) CFU/cm(2) on SS and PE-HD, respectively. In dual cultures with P. fluorescens (ATCC 13525), Lm568 biofilm cell numbers rose by 1.0 and 1.8 log on SS and PE-HD, respectively. Enhanced L. monocytogenes numbers were also observed in the triplex biofilms with Lb. plantarum and P. fluorescens (ATCC 1024) (1.4 and 0.5 log for SS and PE-HD, respectively), whereas the same trend was not observed when L. monocytogenes was paired with Lb. plantarum. Imaging biofilms by scanning electron microscopy (SEM) revealed important architectural changes to the biofilms related to the specific strain combinations. Integration of L. monocytogenes cells into P. fluorescens biofilms significantly (P < 0.05) increased the survival of the pathogen to benzalkonium chloride. These results demonstrate the important role other commensal bacteria play in aiding the survival of foodborne pathogens; hence these factors must be considered when evaluating the effectiveness of biofilm mitigation strategies. 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 85-54-1.

A series of Fe(II) complexes (1-4) and Fe(III) complexes (5-8) from Fe(II)/(III) chloride and N-(8-quinolyl)-X-salicylaldimine Schiff base ligands (Hqsal-X-2/X: X = Br, Cl) were successfully synthesized and characterized by spectroscopic (FT-IR, H-1-NMR), mass spectrometry, thermogravimetric analysis (TGA), and single crystal X-ray crystallographic techniques. The interaction of complexes 1-8 with calf thymus DNA (CT-DNA) was determined by UV-Vis and fluorescence spectroscopy. The complexes exhibited good DNA-binding activity via intercalation. The molecular docking between a selected complex and DNA was also investigated. The in vitro anticancer activity of the Schiff base ligands and their complexes were screened against the A549 human lung adenocarcinoma cell line. The complexes showed anticancer activity toward A549 cancer cells while the free ligands and iron chloride salts showed no inhibitory effects at 100 mu M. In this series, complex [Fe(qsal-Cl-2)(2)]Cl 6 showed the highest anticancer activity aginst A549 cells (IC50 = 10 mu M). This is better than two well-known anticancer agents (Etoposide and Cisplatin). Furthermore, the possible mechanism for complexes 1-8 penetrating A549 cells through intracellular ROS generation was investigated. The complexes containing dihalogen substituents 1, 2, 5, and 6 can increase ROS in A549 cells, leading to DNA or macromolecular damage and cell-death induction. [GRAPHICS] .

Probiotic potential of Enterococcus spp. is widely investigated around the globe. The biochemically and molecular characterized E. faecium strains isolated from Dahi (continental yogurt) were evaluated to tolerate simulated gastric environment, bile, sodium chloride, temperature, and pH. The safety was assessed by disc diffusion, broth microdilution, antibiotic resistance genes screening, and hemolytic ability. Enterococci survived simulated gastrointestinal conditions and depicted growth at temperature (15 to >= 42 degrees C), pH (<= 2.5 to >= 9.5), 0.3% bile salt and 3% NaCl. All strains were sensitive to ampicillin, vancomycin, kanamycin, gentamicin, streptomycin, tetracycline and ciprofloxacin and harbored vanR, vanX, qnrB2, qnrS, tetK, and tetW resistance genes. E. faecium strains inhibited the E. coli (85%) and S. Typhi (50%) whereas the 10% cell-free culture supernatant (CFCS) of E. faecium halted the growth of E. coli while 15% CFCS completely suppressed S. Typhi. The cell-free culture supernatant retained antibacterial nature after pH and proteinase K treatment, however, it lost activity after heat treatment (>= 95 degrees C). The genetic screening revealed that all isolates are capable to produce putrescine biogenic amine. Further assessment of strains for lack of infectivity, cytotoxicity in animals, adhesion to Caco-2 cells and characterization of enterocins is essential to conclude the probiotic potential of these strains.

A series of PVC films stabilized with novel antimicrobial itaconimido aryl 1,3,4-oxadiazoles (D1′-D4′), at absence or presence of various concentrations of multiwalled carbon nanotubes (MWCNTs), was prepared by a conventional solution casting method. D1′-D4′ was prepared via thermal cyclization processes by loss of water for their congruous predecessors itaconimido aryl hydrazides. Elemental analysis and various spectroscopy measurements were used to prove their structures. D1′-D4′ have great antimicrobial activities and some of them showed similar or sometimes higher impact than the reference antibiotic. From TG measurements in nitrogen, they have high thermal stabilities and their decomposition temperatures were above 275-310 degrees C in accordance with substituent groups NH2 and/or OH incorporated into their structures. They have higher thermal stabilizing efficiencies for PVC in comparison with some industrial thermal stabilizers. Inclusion of 0.1-0.5 wt% MWCNTs into PVC films, that were stabilized with D4′, enhanced the composites thermal stability. XRD, SEM as well as TEM were used for ascertaining of incorporation and well dispersion of MWCNTs into PVC matrices. Additionally, the efficacy of stabilization has been proven via a decreased rate of color alteration, mechanical properties change and chains cleavage for PVC. The high antimicrobial and thermal characteristics of these stabilizers afford them a great possibility to secure antimicrobial thermally stable PVC composites. Also, improvement of thermal and mechanical properties of PVC stabilized by D4′ after its incorporation with MWCNTs afford a great possibility to its application in different fields where their thermal resistance and high tensile strength resistance play a very important role.

Sustainable microalgae-based technology for biotransformation of benzalkonium chloride in oil and gas produced water: A laboratory-scale study

Many countries have implemented stringent regulatory standards for discharging produced water (PW) fromthe oil and gas extraction process. Among the different chemical pollutants occurring in PW, surfactants are widely applied in the oil and gas industry to provide a barrier from metal corrosion. However, the release of these substances fromthe shale formation can pose serious hazardous impacts on the aquatic environment. In this study, a low-cost and eco-friendly microalgae laboratory-scale technology has been tested for biotransformation of benzalkonium chloride (BAC(C12) and BAC(C14)) in seawater and PW during 14-days of treatment (spiked at 5 mg/L). From the eight microalgae strains selected, Tetraselmis suecica showed the highest removal rates of about 100% and 54% in seawater and PW, respectively. Suspect screening analysis using liquid chromatography coupled to high-resolution mass spectrometry (LC-HRMS) allowed the identification of 12 isomeric intermediates generated coming from biotransformation mechanisms. Among them, the intermediate [OH-BAC(C12)] was found as the most intense compound generated from BAC(C12), while the intermediate [2OH-BAC(C14)] was found as the most intense compound generated from BAC(C14). The suggested chemical structures demonstrated a high reduction on their amphiphilic properties, and thus, their tendency to be adsorbed into sediments after water discharge. In this study, Tetraselmis suecica was classified as the most successful specie to reduce the surfactant activity of benzalkonium chloride in treated effluents. (c) 2020 The Authors.

Disulfiram-copper activates chloride currents and induces apoptosis with tyrosine kinase in prostate cancer cells

Aim: To elucidates the mechanism that disulfiram/copper complex (DSF/Cu) treatment activates chloride channels and induces apoptosis in prostate cancer cells. Methods: Cellular membrane currents were measured by membrane clamp technique; western blot to detect protein expression; flow cytometry to detect apoptosis; immunofluorescence to detect target protein co-localization, and further validated by a combination of protein-protein interaction and mock protein molecular docking techniques. Results: DSF/Cu activated chloride channels and induced apoptosis in LNCaP (a type of androgen-dependent prostate cancer cells) cells. The chloride currents activated by DSF/Cu were significantly reduced after knockdown of CLC3 with siRNA. In addition, DSF/Cu-activated chloride currents were reduced to background current levels after perfusion with genistein, a highly specific tyrosine kinase inhibitor. Conversely, DSF/Cu failed to activate chloride currents in LNCaP cells after 30 minutes of pre-incubation with genistein. When genistein was removed, and DSF/Cu was added, the activated currents were small and unstable, and gradually decreased. Immunofluorescence in LNCaP cells also showed co-localization of the CLC3 protein with tyrosine kinase 2 beta (PTK2B). Conclusion: DSF/Cu can activate chloride channels and induce apoptosis in LNCaP cells with the involvement of tyrosine kinase. These results provide new insights into the target therapy of prostate cancer.

Voltammetry measurements in lithium chloride-lithium oxide (LiCl-Li2O) salt: An evaluation of working electrode materials

Instrumentation to provide process monitoring (PM) and safeguards for the oxide reduction (OR) step in the electrochemical processing of used oxide nuclear fuel is necessary to ensure equipment is operated as declared. Cyclic voltammetry (CV) has been proposed for real-time monitoring of the operation of an OR process for safeguards purposes. In this study, 316L stainless steel (SS), tantalum (Ta), molybdenum (Mo), tungsten (W), platinum (Pt), and iridium (Ir) were evaluated as potential working electrode (WE) materials based on their chemical inertness, corrosion resistance, and sensitivity in detecting lithium oxide (Li2O) and other chloride salts in the OR electrolyte. Of the electrodes evaluated, 316L SS, Ir, and Pt all performed reasonably well in the lithium chloride-lithium oxide (LiCl-Li2O) electrolyte. SS was operated in the cathodic potential, had reasonable corrosion resistance, and is relatively inexpensive. Ir could be operated in both the cathodic and anodic potentials and was the most corrosion-resistant of the materials evaluated. Pt is limited to the anodic potential range, had reasonable corrosion resistance, and was the most sensitive to Li2O concentrations in the salt. In the development of a stand-alone safeguards instrumentation, our recommendation is a CV probe fitted with both Ir and Pt WEs. The results of this study may also be helpful for anode material selection in other electrometallurgy industries, such as molten salt electrolysis. (C) 2021 Elsevier B.V. All rights reserved.

Synthetic and Mechanistic Implications of Chlorine Photoelimination in Nickel/Photoredox C(sp(3))-H Cross-Coupling

In recent years, the development of light-driven reactions has contributed numerous advances in synthetic organic chemistry. A particularly active research area combines photoredox catalysis with nickel catalysis to accomplish otherwise inaccessible cross-coupling reactions. In these reactions, the photoredox catalyst absorbs light to generate an electronically excited charge-transfer state that can engage in electron or energy transfer with a substrate and the nickel catalyst. Our group questioned whether photo-induced activation of the nickel catalyst itself could also contribute new approaches to cross-coupling. Over the past 5 years, we have sought to advance this hypothesis for the development of a suite of mild and site-selective C(sp(3))-H cross-coupling reactions with chloride-containing coupling partners via photoelimination of a Ni-Cl bond. On the basis of a report from the Nocera laboratory, we reasoned that photolysis of a Ni(III) aryl chloride species, generated by single-electron oxidation of a typical Ni(II) intermediate in cross-coupling, might allow for the catalytic generation of chlorine atoms. Combining this with the ability of Ni(II) to accept alkyl radicals, we hypothesized that photocatalytically generated chlorine atoms could mediate hydrogen atom transfer (HAT) with C(sp(3))-H bonds to generate a substrate-derived alkyl radical that is captured by the Ni center in cross-coupling. A photoredox catalyst was envisioned to promote the necessary single-electron oxidation and reduction of the Ni catalyst to facilitate an overall redox-neutral process. Overall, this strategy would offer a visible-light-driven mechanism for chlorine radical formation enabled by the sequential capture of two photons. As an initial demonstration, we developed a Ni/photoredox-catalyzed alpha-oxy C(sp(3))-H arylation of cyclic and acyclic ethers. This method was extended to a mild fonnylation of abundant and complex aryl chlorides through selective 2-functionalization of 1,3-dioxolane. Seeking to develop a suite of reactions that introduce carbon at all different oxidation states, we explored C(sp(3))-H cross-coupling with trimethyl orthoformate, a common laboratory solvent. We found that trimethyl orthofonnate serves as a source of methyl radical for a methylation reaction via beta-scission from a tertiary radical generated upon chlorine-mediated HAT. Since chlorine radical is capable of abstracting unactivated C(sp(3))-H bonds, our efforts have also been directed at cross-coupling with a range of feedstock chemicals, such as alkanes and toluenes, along with late-stage intermediates, using chloroformates as coupling partners. Overall, this platform enables access to valuable synthetic transformations with (hetero)aryl chlorides, which despite being the most ubiquitous and inexpensive aryl halide coupling partners, are rarely reactive in Ni/photoredox catalysis. Little is known about the photophysics and photochemistry of organometallic Ni complexes relevant to cross-coupling. We have conducted mechanistic investigations, including computational, spectroscopic, emission quenching, and stoichiometric oxidation studies, of Ni(II) aryl halide complexes common to Ni/photoredox reactions. These studies indicate that chlorine radical generation from excited Ni(III) is operative in the described C(sp(3))-H functionalization methods. More generally, the studies illustrate that the photochemistry of cross-coupling catalysts cannot be ignored in metallaphotoredox reactions. We anticipate that further mechanistic understanding should facilitate new catalyst design and lead to the development of new synthetic methods.
