Significance of N-moieties in regulating the electrochemical properties of nano-porous graphene: Toward highly capacitive energy storage devices

The effects of N doping concentration and dopant moieties on the electrochemical properties of nanoporous graphene and their dependence on annealing temperature are investigated. Four types of N moieties – amide, amine, graphitic-N, and oxidized-N – are obtained, which transformed into pyridinic-N and pyrrolic-N upon annealing. The diffusion coefficient (0′) of the ions in the electrode is the maximum at 400 degrees C because of a high level of N doping, whereas the second highest D’ value is obtained at 700 degrees C owing to a high level of reduction and N doping. The highest specific capacitance is obtained for the sample annealed at 400 degrees C. (C) 2018 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.

Effects of deuteration on solid-state NMR spectra of single peptide crystals and oriented protein samples

Extensive deuteration can be used to simplify NMR spectra by diluting and minimizing the effects of the abundant H-1 nuclei. In solution-state NMR and magic angle spinning solid-state NMR of proteins, perdeuteration has been widely applied and its effects are well understood. Oriented sample solidstate NMR of proteins, however, is at a much earlier stage of development. In spite of the promise of the approach, the effects of sample deuteration are largely unknown. Here we map out the effects of perdeuteration on solid-state NMR spectra of aligned samples by closely examining differences in results obtained on fully protiated and perdeuterated samples, where all of the carbon sites have either H-1 or H-2 bonded to them, respectively. The H-2 and N-15 labeled samples are back-exchanged in (H2O)-H-1 solution so that the amide N-15 sites have a bonded H-1. Line-widths in the N-15 chemical shift, H-1 chemical shift, and H-1-N-15 dipolar coupling frequency dimensions were compared for peptide single crystals as well as membrane proteins aligned along with the phospholipids in bilayers with their normals perpendicular to the direction of the magnetic field. Remarkably, line-width differences were not found between fully protiated and perdeuterated samples. However, in the absence of effective H-1-H-1 homonuclear decoupling, the line-widths in the H-1-N-15 heteronuclear dipolar coupling frequency dimension were greatly narrowed in the perdeuterated samples. In proton-driven spin diffusion (PDSD) experiments, no effects of perdeuteration were observed. In contrast, in mismatched Hartmann-Hahn experiments, perdeuteration enhances cross-peak intensities by allowing more efficient spin-exchange with less polarization transfer back to the carbon-bound H-1. Here we show that in oriented sample solid-state NMR, the effects of perdeuteration can be exploited in experiments where H-1-H-1 homonuclear decoupling cannot be applied. These data also provide evidence for the possible contribution of direct N-15-N-15 dilute-spin mixing mechanism in proton-driven spin diffusion experiments. (C) 2019 Published by Elsevier Inc.

Optimization of Hexavalent Chromium Biosorption by Shewanella putrefaciens Using the Box-Behnken Design

Cr(VI) is a ubiquitous pollutant that poses a serious threat to human health. Recently, the use of microorganisms to adsorb heavy metals has attracted research attention. However, there are few studies on the biosorption of Cr(VI) by Shewanella putrefaciens, which is a metal-reducing bacterium. In this paper, single-factor experiments were designed to investigate the effect of hexavalent chromium by Shewanella putrefaciens, and response surface methodology (RSM) based on the Box-Behnken design (BBD) was performed to study the Cr(VI) biosorption behavior of Shewanella putrefaciens. The coefficient of determination (R-2 = 0.811 for Cr(VI)) and probability value (P < 0.05) demonstrated significance for the obtained regression model. The results showed that the model was suitable for experimental data, and the maximum Cr(VI) removal efficiency by Shewanella putrefaciens was 85.68% under the optimum conditions of a contact time of 16.57 h, pH value of 8, and biomass dosage of 0.42 g/L, which were verified by additional experiments. ANOVA and 3D response graph analysis showed that the variables with significant influences were pH and temperature. In addition, scanning electron microscopy (SEM) results demonstrated that after biosorption of Cr(VI) by Shewanella putrefaciens, granular complexes attached to rough cell surfaces were observed. Furthermore, Fourier transform infrared spectroscopy (FT-IR) analysis showed that the distribution of Cr(VI) on the cell surface was related to the carboxyl, ether, amide, hydroxyl, and phosphoric acid groups of Shewanella putrefaciens. This study is useful to explore the process and mechanism of heavy metal adsorption by Shewanella putrefaciens and provide new ideas for the microbial remediation of metal pollution in water.

Template-Assisted Enzymatic Synthesis of Oligopeptides from a Polylactide Chain

Peptides are often attached to polymer materials, as bioactive components, for the control of interactions between the material and its surrounding proteins and cells. However, synthesizing peptides and attaching them to polymers can be challenging and laborious. Herein, we describe the grafting of oligopeptides to an aliphatic polyester, using a one-step chemo-enzymatic synthesis with papain as the biocatalySt. To enable enzyme-mediated functionalization of the polyester, ethyl hept-6-enoylalaninate (grafter) was synthesized and attached to polylactide chains using thiol-ene click reactions. The oligopeptides were grafted onto the polylactide chains using two different synthetic routes: the grafting from strategy, in which the grafter was attached to the polyester prior to oligopeptide synthesis, or the grafting to strategy, in which oligopeptides were synthesized on the grafter first, then attached to the polymer chain. The final products were analyzed and their structures were confirmed using nuclear magnetic resonance (NMR). The peptide attachment was evaluated using size exclusion chromatography (SEC), contact angle measurement and energy-dispersive X-ray spectroscopy scanning electron microscopy (EDS-SEM). Furthermore, the mechanistic aspects of the synthesis of the oligopeptides on the grafter were studied using molecular dynamics (MD) simulations. The simulation revealed that hydrogen bonding (between the P1 amide nitrogen of the grafter backbone and the carbonyl oxygen of D158 in the papain) maintain the grafter in a productive conformation to stabilize the transition state of nitrogen inversion, a key step of the biocatalytic mechanism. Apart from being biologically relevant, both experimental and computational results suggest that the designed grafter is a good template for initiating chemo-enzymatic synthesis. The results also showed that the grafting to strategy was more successful compared to the grafting from strategy. Overall, a successful synthesis of predefined peptide functionalized polylactide was prepared, where the oligopeptides were grafted in an easy, time efficient, and environmentally friendly way.

Regiocontrolled Halogen Dance of Bromothiophenes and Bromofurans

The LDA (lithium diisopropylamide)-promoted regiocontrolled halogen dance of alpha-bromothiophenes and alpha-bromofurans is described. Bromothiophenes bearing a diethyl acetal moiety undergo selective deprotonation at the beta-position adjacent to the bromo group. In contrast, oxazoline, ester, and amide groups act as directing groups in the initial lithiation step to generate a carbanion at the beta-position neighboring the directing group to exclusively give the other regioisomer. These results can be applied to the regiocontrolled halogen dance of bromofuran derivatives.

Raman spectral imaging of (CHN)-C-13-H-2-N-15-labeled a-synuclein amyloid fibrils in cells

Parkinson’s disease is characterized by the intracellular accumulation of alpha-synuclein (alpha-syn) amyloid fibrils, which are insoluble, beta-sheet-rich protein aggregates. Raman spectroscopy is a powerful technique that reports on intrinsic molecular vibrations such as the coupled vibrational modes of the polypeptide backbone, yielding secondary structural information. However, in order to apply this method in cells, spectroscopically unique frequencies are necessary to resolve proteins of interest from the cellular proteome. Here, we report the use of (CHN)-C-13-H-2-N-15-labeled alpha-syn to study the localization of preformed fibrils fed to cells. Isotopic labeling shifts the amide-I (C-13=O) band away from endogenous C-12=O vibrations, permitting secondary structural analysis of internalized alpha-syn fibrils. Similarly, C-13-H-2 stretches move to lower energies in the cellular quiet region, where there is negligible biological spectral interference. This combination of well-resolved, distinct vibrations allows Raman spectral imaging of a-syn fibrils across a cell, which provides conformational information with spatial context.

Design, synthesis, anti-cancer evaluation and binding mode studies of benzimidazole/benzoxazole linked beta-carboline derivatives

A new series of benzimidazole/benzoxazole linked beta-carbolines (9a-j) were rationally designed and synthesized by combining two different anti-cancer fragments. The new hybrid beta-carbolines are subjected to anti-cancer screening against four different human cancer cell lines such as MCF-7 (breast), A549 (lung), Colo-205 (colon) and A2780 (ovarian) by using standard MIT assay. These hybrid beta-carbolines exhibited significant and high fold anti-cancer activity against MCF-7 cell lines than reference standard. They are also proved to be effective against A549 and Colo-205 cell lines. Further, compound 9b, 9c from benzimidazole and 9i from benzoxazole series have exhibited maximum anti-cancer activity among these hybrid beta-carbolines. Later, all of the hybrid beta-carbolines were subjected to molecular interaction analysis against a few selected kinase targets such as cdc-like kinase (CLK-1 to CLK-4), epidermal growth factor reductase (EGFR) kinase, protein (ATR) kinase along with APC-Asef interface. The violin plot of binding energies of 9a-9j have suggested them as good kinase binders. Result interpretation suggested hybrid beta-carbolines as promising CLK binders. The anti-cancer data of new hybrid beta-carbolines against MCF-7 cell lines are in agreement with parent beta-carboline skeleton. (C) 2020 Elsevier B.V. All rights reserved.

Transition metal-free direct dehydrogenative arylation of activated C(sp(3))-H bonds: synthetic ambit and DFT reactivity predictions

A transition metal-free dehydrogenative method for the direct mono-arylation of a wide range of activated C(sp(3))-H bonds has been developed. This operationally simple and environmentally friendly aerobic arylation uses tert-BuOK as the base and nitroarenes as electrophiles to prepare up to gram quantities of structurally diverse sets (>60 examples) of alpha-arylated esters, amides, nitriles, sulfones and triaryl methanes. DFT calculations provided a predictive model, which states that substrates containing a C(sp(3))-H bond with a sufficiently low pK(a) value should readily undergo arylation. The DFT prediction was confirmed through experimental testing of nearly a dozen substrates containing activated C(sp(3))-H bonds. This arylation method was also used in a one-pot protocol to synthesize over twenty compounds containing all-carbon quaternary centers.
