Building on recent developments, we compare performance of two distinct protocols, namely SMD-mPW1PW91/6-311+G(2d,p) and CPCM-OLYP/pcSseg-2, for the computation of N-15 chemical shifts of nitrogenated aromatic compounds. The latter shows best overall performance (MAD 5.3 ppm) albeit results in chloroform favors the former. [GRAPHICS] .

Dearomatization of indole derivatives offers a straightforward approach to access diverse indolines. To date, the corresponding dearomative transformations involving electron-deficient indoles are limited. Herein, we report a one-electron strategy for dearomatization of electron-deficient indoles via a photoredox-catalyzed hydroalkylation employing commercially available glycine derivatives as the hydrofunctionalization reagents. Followed by DBU-mediated lactamization, structurally appealing lactam-fused indolines are obtained in good to excellent yields with exclusive selectivity.

The purpose of this study was to develop and validate a sensitive method for the determination of ultra trace levels of reactive bromine species (RBS) in water. To derivatized RBS, water samples were transferred into vials pre-fortified with an appropriate dose of derivative reagent 3,5-dimethyl-1H-pyrazole (DMPZ). RBS in water samples could be rapidly and stoichiometrically (1:1) derivatized to 4-bromo-3,5-dimethyl-1H-pyrazole, which was directly analyzed on an ultra performance liquid chromatography coupled with triple quadrupole tandem mass spectrometry. Parameters influencing the derivatization efficiency including reaction time, temperature, DMPZ dose, and pH were optimized to be: a molar concentration ratio of DMPZ to RBS a 100:1, pH 5-10, and reaction for 10 min at room temperature. In addition, near 100% of RBS was recovered when using water with salinity of 0-55 as the spiking matrices, suggesting that salinity had negligible effect on the derivatization efficiency. Under the optimized conditions, interday and intraday analyses showed that the recoveries of RBS ranged from 88.0% to 109.8% for samples spiked with 18.0-540 pmol L-1 of RBS, with relative standard deviations less than 3.7%. The method limit of detection and limit of quantification for RBS were 5.8 pmol L-1 and 18.0 pmol L-1, respectively. Compared with currently available methods, our method greatly improved the analytical sensitivity by lowering the limit of detection for more than 100 times. The developed method displayed high reliability and reproducibility in the analysis of ultra trace levels of RBS in seawater and other real fresh water samples.

Bis(pyrazolyl)alkanes are a prolific class of ligands for catalysis, accessible by the condensation between bis(pyrazolyl)methanones and carbonyls. In this report, we describe a nucleophile-catalyzed innovation on this condensation that avoids the transition metals, high temperatures, reagent excess, and air-sensitive reagents common among the existing protocols. Significantly, this method accommodates sterically hindered and electronically diverse pyrazoles and aldehydes, applicable for systematic ligand optimization. Furthermore, our scope includes azoles and bridging functional groups previously unreported for this reaction, promising for new heteroscorpionate catalysts. We provide the first direct evidence for an elusive reaction intermediate and characterize the most complete mechanism for this condensation.

Antibacterial properties of microencapsulated Lactobacillus plantarum cell-free supernatant (CFS) in combinations with aqueous or ethanolic propolis extract at doses of 1% against fish spoilage bacteria were investigated. Microencapsulated samples contained more than 17 compounds, of which furyl alcohol, acetic acid, maltol, and 2(5H) furanon were identified as common compounds. The effects of microencapsulated CFS from L. plantarum in combination with or without propolis extracts on the fish spoilage bacteria varied according to the bacterial species. Among the fish spoilage bacteria, the highest antimicrobial activity of samples was observed against P. damselae with >15.5 mm inhibition diameter zone. Pure and microencapsulated CFS from L. plantarum showed the lowest antimicrobial effects on P. mirabilis with a corresponding inhibition diameter zone of 8.33 and 8.00 mm. Microencapsulated CFS from L. plantarum in combination with aqueous propolis extract had 25 mg/ml of MIC and 50 mg/ml of MBC on all bacteria although the bactericidal effect of microencapsulated samples in combination with ethanolic propolis extract occurred at a level of above 50 mg/ml. The study results revealed that co-microencapsulation of CFS obtained from L. plantarum with propolis extract, especially its aqueous extract, could be potentially used as antimicrobial agents to overcome microbial growth in foods.

Errors were discovered regarding the published equation coefficients of Yao and co-workers (2017) for mathematically describing the solubility of 3,5-dimethylpyrazole in nine organic solvents using the NRTL model. Larger differences were found between our back-calculated data and those reported in the authors’ published paper. The equation parameters were re-regressed based on the reported solubility data.

CO2 capture by ionic liquids has been successfully achieved, indicating that the adsorption of CO2 plays an important role in the activation and transformation of CO2. In this work, highly efficient capture of CO2 is investigated with several novel ILs, which were prepared from bicyclic amidine (DBN) with pyrazole derivatives. Among the kinds of DBN-based ILs, it is found that the optimal absorption capacity (0.93 mol CO2/mol IL) can be achieved by [DBNH][3-MethylPyr] at 40 degrees C and atmospheric pressure. In view of analysis, the significant increase in CO2 capacity was affected by the reactivity of activated nitrogen, steric hindrance and the type of substituents. On the basis of the spectroscopic investigation and Density Functional Theory (DFT) calculation, the absorption mechanism was illustrated, it was verified that anions can react with CO2 to form carbamates. Meanwhile, charge analysis reasonably elucidated the diversity of absorption capacity in various ILs. It suggested that electric-charge distribution of activated nitrogen in pyrazole ring system can play an important role in determining the reaction of ILs with CO2. Consequently, DBN-based ILs can be excellent candidates for CO2 capture. (C) 2020 Elsevier B.V. All rights reserved.

A berberine 9-O-pyrazole alkyl derivative, a chemical compound (called B3) previously synthesized by our group, shows anti-cancer activity. However, B3 lacks targeting cytotoxicity to cancer cells, leading to obvious toxic side effects on normal cells. To solve this problem, here, we prepared a drug delivery system, namely, AS1411-GO/B3 for tumor targeting, in which nano-graphene oxide (GO) sheets were employed as the drug carrier, and the aptamer AS1411 was conjugated onto GO for tumor targeting. GO also had a photothermal effect, which helped the release of B3 from GO as well as the thermal cytotoxicity to cells. We found that the release of B3 could respond to acid conditions, indicating that the tumor intracellular environment could promote the release of B3, thus allowing it to perform chemotherapy effects. This system could also release B3 in response to photothermal heating, moreover, combined photothermal therapy and chemotherapy to improve the anticancer activity was achieved. This AS1411-GO/B3 platform with chemo-photothermal synergetic therapy provides a very promising treatment for tumors.
