The mechanism of carboxylative cyclization of propargylamine by N-heterocyclic carbene complexes of Au(I)

The complex [Au(IPr)(2-oxazolidinone)] (1 = IKa) was prepared from reaction of [Au(IPr)Cl] (2), K2CO3, and propargyl amine (PPA). Kinetic studies have been performed for acid cleavage of 1 to yield the oxazolidinone product and an [Au(IPr)(X)] adduct. The fastest rates of cleavage were found to occur for the hydrogen chloride salt of PPA (PPA-HCl) and for the CO2 adduct of PPA, PPA-CO2 = the carbamic acid (CA). This transformation was studied as a function of [CA], pressure of CO2 as well as temperature. Detailed computational studies support the formation of a key intermediate and are also in agreement with a rapid carbonylation/decarbonylation reaction. The computed reactions mechanisms for addition of PPAHCl and CA are also presented as well as the crystal structure of 1. (C) 2020 Elsevier B.V. All rights reserved.

Molecular insight into flow resistance of choline chloride/urea confined in ionic model nanoslits

Choline chloride/urea (1:2) is the most widely used deep eutectic solvent, which has attracted much attention due to its excellent advantages of low cost, environment friendly and easy synthesis. In this work, nanofriction-based molecular dynamics simulations were performed to investigate the effect of interfacial hydrophilicity on the flow resistance of Choline chloride/urea (1:2) confined in ionic model nanoslits. Simulation results showed that the flow resistance of the choline chloride/urea system increases with the increasing interfacial hydrophilicity. Urea molecules form a preferential adsorption layer on the wall. As the interfacial hydrophilicity increases, the number of urea molecules in the interfacial adsorption layer increased, whereas the stability decreased. Unique confined spatial distributions of urea molecules greatly contribute to ionic association between choline cations and chloride anions. Furthermore, with the increase of interfacial hydrophilicity, orientation distributions of urea molecules in the adsorption layer are more orderly, then causing a decrease in the average hydrogen bond number (N-HB) of urea molecules. Moreover, the more the N-HB of urea molecules, the better is the stability in the interfacial adsorption layer, which in turn results in less flow resistance. (C) 2020 Elsevier B.V.

Ethyl acetate fraction from Nymphaea hybrida Peck modulates inflammatory responses in LPS-stimulated RAW 264.7 cells and acute inflammation murine models

Ethnopharmacological relevance: Nymphaea hybrida Peck is used as a traditional medicinal herb for treating pain and inflammatory diseases, and known for its ornamental value and as a hot drink. However, the effects of N. hybrida polar fractions on lipopolysaccharide (LPS)-induced in vitro inflammation model and acute inflammation murine models have yet to be evaluated. Aim of the study: The aim of this study was to elucidate the anti-inflammatory effects of N. hybrida ethanol extract (NHE) and its polar fractions: petroleum ether (PE), methylene chloride (MC), ethyl acetate (EA), methanol (ME), and water (WA). The underlying molecular mechanisms of active fraction in LPS-stimulated RAW 264.7 murine macrophages were further investigated. Material and methods: Fractions with potential anti-inflammatory effects were screened using direct nitric oxide (NO) radical scavenging and cyclooxygenase (COX)-2 inhibition assays in vitro. The anti-inflammatory properties of potential fraction were evaluated in LPS-stimulated RAW264.7 cells, xylene-induced ear edema, carrageenaninduced paw edema and xylene-induced Evans blue exudation of acute inflammation murine models. The regulation of nuclear factor-kappa B (NF-kappa B) and mitogen-activated protein kinase (MAPK) signaling pathways were investigated using western blotting and immunofluorescence. Results: Compared to other polar fractions, NHE-EA displayed higher phenol and flavonoid content, and exerted greater activity in direct NO radical scavenging and COX-2 inhibition assay in vitro. NHE-EA markedly decreased the levels of inflammatory mediators, NO and prostaglandin E-2 (PGE(2)), by suppressing the over-expression of inducible nitric oxide synthase (iNOS) and COX-2 in LPS-stimulated RAW264.7 cells. The NHE-EA fraction dose dependently alleviated over-elevation of LPS-associated intracellular calcium and decreased the abnormal secretion of pro-inflammatory cytokines, tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), IL-6, and interferon-gamma (IFN-gamma). The combination with NHE-EA effectively attenuated the activation and nuclear trans location of NF-kappa B p65, and the phosphorylation of extracellular signal-regulated kinases (ERK), c-Jun N-terminal kinases (JNK), and p38 kinases of MAPK pathways. NHE-EA could significantly ameliorate the degree of swelling of the mice ear and paw, the skin exudation of Evans blue and the excessive secretion of inflammatory cytokines. Conclusion: Our results demonstrated that NHE-EA was the most active polar fraction of N. hybrida extracts. It inhibited the LPS-associated inflammatory response by blocking the activation of NF-kappa B and MAPKs pathways in RAW264.7 cells. It also effectively alleviated the inflammatory response of acute inflammation. These results

Biomimetic superhydrophobic membrane with multi-scale porous microstructure for waterproof and breathable application

The multifunctional membranes with superior waterproofness and breathability have been extensively used in high-end wearable protection, desalination, and the aerospace industry. A multi-layered, biomimetic and superhydmphobic membrane is designed via a facile two-step strategy of phase-conversion and electrospraying. The homogeneous reticular porous microstructure with a stellate spherulite surface formed by introducing sodium chloride (NaCl) during the phase-conversion process provides an effective vapor-permeable channel for the membrane. Zirconium carbide (ZrC)/silica (SiO2) as two-component inorganic powders with different particle sizes can construct bio-inspired, hierarchical, and superhydrophobic layers. Simultaneously, the synergistic interactions between the components can preferably inspire the photo-to-thermal conversion properties of membranes, further accelerating the efficient transport of water vapor. The ultrathin hierarchical nanoporous composite membrane exhibits the excellent breathability of 11.9 kg m(-2) d(-1) and decent waterproofness of 60.71 kPa. An ultrahigh WCA of up to 167.3 degrees gives a stabilized superhydrophobic surface to the high moisture-permeable membrane while possessed robust reusable self-cleaning and photo-to-thermal properties. Furthermore, the superior performances with the tremendous potential for application prospects in various fields.

Establishment of Pediatric Reference Intervals for Routine Laboratory Tests in Korean Population: A Retrospective Multicenter Analysis

Background: Reference intervals defined for adults or children of other ethnicities cannot be applied in the evaluation of Korean pediatric patients. Pediatric reference intervals are difficult to establish because children are in their growing stage and their physiology changes continuously. We aimed to establish reference intervals for routine laboratory tests for Korean pediatric patients through retrospective multicenter data analysis. Methods: Preoperative laboratory test results from 1,031 pediatric patients aged 0 month-18 years who underwent minor surgeries in four university hospitals were collected. Age- and sex-specific reference intervals for routine laboratory tests were defined based on the Clinical and Laboratory Standards Institute (CLSI) EP28-A3c guidelines. Results: The pediatric reference intervals determined in this study were different from existing adult reference intervals and pediatric reference intervals for other ethnicities. Most tests required age-specific partitioning, and some of those required sex-specific partitioning for at least one age-partitioned subgroup. Erythrocyte sedimentation rate, monocyte percentage, basophil percentage, activated partial thromboplastin time, glucose, cholesterol, albumin, bilirubin, chloride, and C-reactive protein did not show any difference between age- or sex-partitioned subgroups. Conclusions: We determined Korean pediatric reference intervals for hematology, coagulation, and chemistry tests by indirect sampling based on medical record data from multiple institutions. These reference intervals would be valuable for clinical evaluations in the Korean pediatric population.

Degradation of hydroxychloroquine by electrochemical advanced oxidation processes

In this work, the degradation of hydroxychloroquine (HCQ) drug in aqueous solution by electrochemical advanced oxidation processes including electrochemical oxidation (EO) using boron doped diamond (BDD) and its combination with UV irradiation (photo-assisted electrochemical oxidation, PEO) and sonication (sono-assisted electrochemical oxidation, SEO) was investigated. EO using BDD anode achieved the complete depletion of HCQ from aqueous solutions in regardless of HCQ concentration, current density, and initial pH value. The decay of HCQ was more rapid than total organic carbon (TOC) indicating that the degradation of HCQ by EO using BDD anode involves successive steps leading to the formation of organic intermediates that end to mineralize. Furthermore, the results demonstrated the release chloride (Cl-) ions at the first stages of HCQ degradation. In addition, the organic nitrogen was converted mainly into NO3- and NH4+ and small amounts of volatile nitrogen species (NH3 and NOx). Chromatography analysis confirmed the formation of 7-chloro-4-quinolinamine (CQLA), oxamic and oxalic acids as intermediates of HCQ degradation by EO using BDD anode. The combination of EO with UV irradiation or sonication enhances the kinetics and the efficacy of HCQ oxidation. PEO requires the lowest energy consumption (EC) of 63 kWh/m(3) showing its cost-effectiveness. PEO has the potential to be an excellent alternative method for the treatment of wastewaters contaminated with HCQ drug and its derivatives.

Functionalized Core-Shell Polystyrene Sphere-Supported Alkaline Imidazolium Ionic Liquid: An Efficient and Recyclable Catalyst for Knoevenagel Condensation

A supported alkaline imidazolium ionic liquid catalyst with an ionic liquid shell and polystyrene core was synthesized. The coreshell structure was achieved by swelling polymerization of 4-vinylbenzyl chloride and divinylbenzene around polystyrene particles followed by quaternization reaction with 1-propyl-1H-imidazole and ion exchange. The results obtained from FTIR, SEM, TEM, TGA, DLS, and elemental analysis indicated that the ionic liquid shell was successfully coated on polystyrene spheres. The core-shell catalyst displayed excellent activity and solvent tolerance for Knoevenagel condensation of benzaldehyde with ethyl cyanoacetate because of its good dispersion, low mass-transfer resistance, and good swelling property. Meanwhile, it exhibited superb stability and recyclability, benefitting from the active species being anchored to the highly cross-linked polymer carrier. The catalyst was reused 10 times in water or methanol without significant change in catalytic activity, composition, and microstructure. Moreover, the catalytic performance of the prepared catalyst was weakened by the increased mass-transfer resistance with the movement of active sites from the surface to the interior of the carrier.
