Metal-Free Triazine-Incorporated Organosilica Framework Catalyst for the Cycloaddition of CO2 to Epoxide under Solvent-Free Conditions

The silicon-based materials with enriched superficial Si-OH groups are candidates in the field of the cycloaddition of CO2 to epoxide to cyclic carbonate; meanwhile, the triazine ring with a nitrogenrich structure has shown a high adsorption affinity toward CO2 to polarize CO2 On this basis, a metal-free triazine-incorporated organosilica framework (SiTIOF) containing triazine rings, -NH, and Si-OH was prepared by substitution reaction and then a hydrothermal method. The prepared SiTIOF exhibited an outstanding catalytic activity for the cycloaddition of CO2 to epoxide with the cocatalyst tetrabutylammonium bromide (Bu4NBr) due to the triazine unit and multiple hydrogen bond donors (-NH, -OH). Besides, the SiTIOF catalyst could be reused six times and has good versatility to various epoxides with CO2 cycloaddition. Moreover, the possible reaction mechanism with a hydrogen bond donor (HBD) and halide anion synergistic catalysis was proposed.

Iodosulfuron-Methyl-Based Herbicidal Ionic Liquids Comprising Alkyl Betainate Cation as Novel Active Ingredients with Reduced Environmental Impact and Excellent Efficacy

A new family of bio-based herbicidal ionic liquids (HILs) has been synthesized starting from the renewable resource glycine betaine (a derivative of natural amino acids). After esterification, the obtained alkyl betainate bromides containing straight alkyl chains varying from ethyl to octadecyl were combined with a herbicidal anion from the sulfonylurea group (iodosulfuron-methyl). The melting points of the iodosulfuron-methyl-based salts were in a range from 51 to 99 degrees C, which allows their classification as ionic liquids (ILs). In addition, the new HILs exhibited good affinity for polar and semipolar organic solvents, such as DMSO, methanol, acetonitrile, acetone, and chloroform, while the presence of bulky organic cations reduced their solubility in water. The synthesized products turned out to be stable during storage at 25 degrees C for over 6 months; however, at 75 degrees C they underwent fast, progressive degradation and released volatile byproducts. The values of the logarithm of the octanol-water partition coefficient of ILs with alkyls longer than hexyl occurred in the safe zone (between 0 and 3); hence, the risk of their migration into groundwater after application or the possibility of their bioaccumulation in the environment is lower in comparison with the currently available commercial form (iodosulfuron-methyl sodium salt). Greenhouse studies confirmed a very high herbicidal efficacy for the obtained salts toward tested plants of oilseed rape, indicating that they may become an attractive replacement for the currently available sulfonylurea-based formulations.

Structure based designing of benzimidazole/benzoxazole derivatives as anti-leishmanial agents

Folates are essential biomolecules required to carry out many crucial processes in leishmania parasite. Dihydrofolate reductase-thymidylate synthase (DHFR-TS) and pteridine reductase 1 (PTR1) involved in folate biosynthesis in leishmania have been established as suitable targets for development of chemotherapy against leishmaniasis. In the present study, various computational tools such as homology modelling, pharmacophore modelling, docking, molecular dynamics and molecular mechanics have been employed to design dual DHFR-TS and PTR1 inhibitors. Two designed molecules, i.e. 2-(4-((4-nitrobenzyl)oxy)phenyl)-1H-benzo[d]imidazole and 2-(4-((2,4-dichlorobenzyl)oxy)phenyl)-1H-benzo[d]oxazolemolecules were synthesized. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay was performed to evaluate in vitro activity of molecules against promastigote form of Leishmania donovani using Miltefosine as standard. 2-(4-((4-nitrobenzyl)oxy)phenyl)-1H-benzo[d]imidazole and 2-(4-((2,4-dichlorobenzyl)oxy)phenyl)-1H-benzo[d]oxazolemolecules were found to be moderately active with showed IC50 = 68 +/- 2.8 mu M and 57 +/- 4.2 mu M, respectively.

Experimental and process simulation of hydrate-based CO2 capture from biogas

This study experimentally investigated the effects of operation conditions for the CO2 capture from biogas by clathrate hydrate formation. The experiments were tested at 3.0 MPa and 278 K in the present of 5.0 wt % tetran-butylammonium bromide (TBAB). In addition, the dissociation enthalpies of CH4/CO2 hydrates in TBAB solution was calculated for energy consumption. The hydrate process simulation with Aspen Plus was carried out at the same experimental conditions to simulate the actual hydrate-based CO2 capture (HBCC), and the energy consumption of this process was analyzed. Experimental results show that the CH4 fraction in the residual gas phase increased with the decrease of gas liquid volume ratio (R-v). R-v decreased from 35.93 to 3.61 while the concentration of CH4 in residual gas increased from 80.5 mol % to 92.76 mol %. The CH4 concentration in residual gas phase was enriched from 67.00 mol% to 97.00 mol% by two stages of HBCC. Process simulation results showed that the energy cost was 1.17 kWh/kg (CH4). According to the handing capacity of the feed gas, the energy cost was 0.390 kWh/kg (biogas), which was lower than that by chemical absorption method. After adjusting the process parameters and increasing exhaust gas energy recovery, the energy consumption was reduced to 0.357 kWh/kg (biogas). The energy consumption could be decreased to 0.204-0.223 kWh/kg (biogas) by using static hydration enhancement technology.

Detection of Trace-Level Nitroaromatic Explosives by 1-Pyreneiodide-Ligated Luminescent Gold Nanostructures and Their Forensic Applications

By attaching thel-pyreneiodide ancillary ligand to the surface of polyvinylpyrrolidone-stabilized gold (Au:PVP) cluster or the cetyltrimethyl ammonium bromide-stabilized gold (Au:CTAB) nanorod, a new class of luminescent mixed ligand-stabilized gold nanostructures is synthesized. This postsynthetic surface modification method followed by us is a comparatively easier and hassle-free technique to acquire surface-active luminescent ‘functional nanomaterials. Careful analyses of transmission electron microscopy images revealed that the sizes of these Au-clusters or Au-nanorods remain unchanged without any noticeable aggregation in the medium. Owing to the formation of an excimer within the neighboring pyrenes mounted on the surface of core nanostructures (i.e., Au:PVP nanocluster and Au:CTAB nanorod), the resulting pyrenegrafted nanocomposites exhibit strong emission characteristics. The strong excimer emission is significantly quenched in the presence of electron-deficient chemical inputs, and this phenomenon can be used for analytical purposes. Using these luminescent Au-nanomaterials, we demonstrate a selective detection and sensing of trace-level nitroaromatic explosives (e.g., trinitrotoluene, trinitrophenol (TNP), dinitrotoluene, 4-nitrotoluene, etc.). It was observed that the Py-Au:PVP nanocluster is equally effective for explosive detection in both solution and solid phases with the limit of detection up to 10 nanomolar. A high Stern-Volmer constant of up to 3.88 X 10(6) M-1 was seen in the case of TNP in anhydrous methanol at 298 K. The deactivation pathway operating within the Py-Au:PVP nanocluster and the analytes is thought to be a result of a predominating static quenching process, where a nonfluorescent D-A supramolecular adduct is formed in the medium. Py-Au:PVP has also been successfully used to develop latent fingerprints from nonporous surfaces under an exposure of 365 nm UV light. The results suggest that these new composite materials could behave as potential functional nanomaterials, which might be a promising alternative for on-the-spot detection of explosive traces as well as for easy visualization of latent fingerprints.

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.

Structure-cytotoxicity relationship profile of 13 synthetic cathinones in differentiated human SH-SY5Y neuronal cells

Synthetic cathinones also known as beta-keto amphetamines are a new group of recreational designer drugs. We aimed to evaluate the cytotoxic potential of thirteen cathinones lacking the methylenedioxy ring and establish a putative structure-toxicity profile using differentiated SH-SY5Y cells, as well as to compare their toxicity to that of amphetamine (AMPH) and methamphetamine (METH). Cytotoxicity assays [mitochondrial 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) reduction and lysosomal neutral red (NR) uptake] performed after a 24-h or a 48-h exposure revealed for all tested drugs a concentration-dependent toxicity. The rank order regarding the concentration that promoted 50 % of toxicity, at 24 h exposure, by the MTT assay was: 3,4-dimethylmethcathinone (3,4-DMMC) > METH > mephedrone = alpha-pyrrolidinopentiophenone > AMPH approximate to methedrone > pentedrone > buphedrone approximate to flephedrone > alpha-pyrrolidinobutiophenone > methcathinone N-ethylcathinone > alpha-pyrrolidinopropiophenone > N,N-dimethylcathinone approximate to amfepramone. Apoptotic cell death signs were seen for all studied cathinones. 3,4-DMMC, methcathinone and pentedrone triggered autophagy activation, as well as increased reactive oxygen species production, and N-acetyl-L-cysteine (NAC) totally prevented that rise. Importantly, NAC was also able to prevent the cytotoxicity promoted by 6 tested drugs, ruling for an involvement of oxidative stress in the toxic events observed. The increased lipophilic chain on the alpha carbon, the presence and the high steric volume occupied by the substituents on the aromatic ring, and the substitution of the pyrrolidine ring by its secondary amine analogue have proved to be key points for the cytotoxicity profile of these cathinones. The structure-toxicity relationship established herein may enlighten future human relevant mechanistic studies, and future clinical approaches on intoxications.

Interactions in the mixed micelles of monomeric and gemini surfactants: Influence of some co-solvents as a function of temperature

Mixed micellar behavior of a series of m-2-m cationic gemini surfactants (where m= 10, 12 and 14) with monomeric surfactants (dodecyltrimethylammonium bromide, tetradecyltrimethylammonium bromide and cetyltrimethylammonium bromide) has been studied in aqueous and in aqueous n-propanol, n-butanol, tertiary butanol, propylene glycol and glycerol solutions using conductivity, surface tension, viscosity and dynamic light scattering techniques at 298.15, 308.15 and 318.15 K, respectively. In mixtures of 10-2-10 with monomeric surfactants, the synergistic interactions increase with the chain length of monomeric surfactants whereas the mixtures with 12-2-12 and 14-2-14 exhibit the opposite trends. However, the synergistic interactions decrease with the increase in temperature of all the mixtures. The thermodynamic and surface parameters have been evaluated and the influence of the variations in hydrophobic chain length of the surfactants and the type of the co-solvent on these parameters has been discussed. The hydrodynamic diameter increases with the chain length of the surfactants. (C) 2015 The Authors. Published by Elsevier B.V. on behalf of King Saud University.

Circ_0010729 regulates hypoxia-induced cardiomyocyte injuries by activating TRAF5 via sponging miR-27a-3p

Ischemic cardiomyopathy is a severe cardiovascular disease with high mortality. Circular RNAs (circRNAs) are widely regulated in diverse human diseases, including Ischemic cardiomyopathy. This study aimed to investigate a novel functional mechanism of circRNA circ_0010729 in hypoxia-induced cardiomyocyte injuries. Human cardiomyocytes (AC16) were exposed to hypoxia to mimic ischemic cardiomyopathy in vitro. Cell viability, apoptosis/necrosis and glycolysis progress, were determined using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay, flow cytometry assay and glycolysis stress test, respectively. Cell apoptosis was also assessed by the activity of cleaved caspase-3/7. The levels of glycolysis-related proteins and tumor necrosis factor receptor-associated factor 5 (TRAF5) were examined by western blot. The expression of circ_0010729 and miR-27a-3p was measured by real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR). The prediction about the targeted relationship was verified by dual-luciferase reporter assay, RNA immunoprecipitation (RIP) assay and RNA pull-down assay. As a result, hypoxia treatment inhibited cell viability, induced cell apoptosis and blocked glycolysis, however, these injuries were alleviated by circ_0010729 knockdown. MiR-27a-3p was targeted by circ_0010729, and miR-27a-3p inhibition reversed the role of circ_0010729 knockdown, leading to the deterioration of cell injuries. Further, TRAF5 was a target of miR-27a-3p, and circ_0010729 upregulated the expression of TRAF5 by sponging miR-27a-3p. MiR-27a-3p restoration enhanced cell viability, depleted cell apoptosis and promoted glycolysis of hypoxia-induced AC16 cells, while these effects were abolished by TRAF5 overexpression. In conclusion, circ_0010729 knockdown alleviated hypoxia-induced AC16 cell injuries by mediating the miR-27a-3p/TRAF5 axis.

MicroRNA-130b inhibits cerebral ischemia/reperfusion induced cell apoptosis via regulation of IRF1

OBJECTIVE: Cerebral ischemia/reperfusion (CIR) frequently causes serious disabilities and correlates with certain neurological processes. Some studies have shown that microRNAs (miRNAs) exert a neuroprotective effect by modulating the inflammatory process in CIR. However, the biofunction and the mechanism of miR-130b in CIR need to be fully elucidated. MATERIALS AND METHODS: An oxygen-glucose deprivation/reperfusion (OGD/R) model was constructed using SH-SYSY cell line to analyze the function of miR-130b in CIR. Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was used to examine the expression levels of miR-130b and IRF1. Western blot was performed to detect the protein levels of IRF1, Bax, and Bcl-2. Cell viability was determined using MTT (3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assays. Dual-Luciferase reporter assay was conducted to confirm the target gene of miR-130b. RESULTS: In this study, we found that miR-130b level was prominently decreased after treatment with OGD/R. Through gain and loss assays, we concluded that miR-130b restoration promoted cell proliferation and inhibited cell apoptosis in OGD/R-treated cells. Moreover, we also identified IRF1 as an important target of miR-130b. Additionally, IRF1 knockdown remarkably abrogated the protection mediated by miR-130b against the injuries in OGD/R-treated cells. CONCLUSIONS: Taken together, our results suggested that miR-130b facilitated cell viability and suppressed cell apoptosis of CIR via negatively regulating of IRF1.
