Iron-catalysed hydroboration of imines and nitriles has been developed under low catalyst loading (1 mol%) in the presence of HBpin. A wide scope of substrate was found to smoothly undergo hydroboration, including electron releasing/withdrawing and halogen substitution patterns and cyclic substrates which all afforded the corresponding amines in good to excellent yields. Dihydroboration of nitriles was achieved conveniently under solvent free and additive free conditions. Promisingly, this catalytic system is also capable of the hydroboration of challenging ketimine substrates. Preliminary kinetic analysis of imine hydroboration reveals a first-order dependence on catalyst concentration. Both HBpin and 4-fluorophenyl-N-phenylmethanimine (1b) appear to exhibit saturation kinetics with first order dependence up to 0.5 mmol HBpin and 0.75 mmol imine, respectively. Temperature-dependent rate experiments for imine hydroboration have also been explored. Activation parameters for the hydroboration of (PhC)-Ph-F = NPh (1b) were determined from the Eyring and Arrhenius plots with Delta S-not equal, Delta H-not equal, and E-a values of -28.69 (+/- 0.3) e.u., 12.95 (+/- 0.04) kcal mol(-1), and 15.22 (+/- 0.09) kcal mol(-1), respectively.

The Name is 1-Phenylurea. Through research, I have a further understanding and discovery of 64-10-8.

Background Accurate reflux episode identification is crucial for pH-impedance interpretation. Individual reflux episode characteristics associated with inter-reviewer concordance are incompletely understood. Methods Ambulatory pH-impedance studies from 19 GERD patients (median age 52 years, 78.9% F) were analyzed by 5 reviewers. Metadata from pH-impedance studies were exported to a dedicated software tool designed to compare episode-by-episode identification between reviewers within a +/- 7.5 s window. Patient position, acidic vs. nonacidic episodes, acid clearance time (ACT), bolus clearance time (BCT), and proximal extent of reflux episodes were compared between episodes identified by all reviewers against those identified by automated analysis, and one to four reviewers, respectively. Results Automated analysis identified 1644 episodes (median 78 episodes per patient, IQR 64-108), of which 84.9% were identified by >= 3 reviewers and 57.1% by all reviewers; 339 unique episodes were added by at least 1 reviewer. Characteristics defining 5 reviewer concordance included acid reflux episodes (88.9%), upright episodes (88.4%), high proximal extent (median 17 cm, IQR 15-17 cm), and longer acid clearance times (67.0 s, IQR 29.0-146.0 s) (P < 0.001 compared to 1-4 reviewer concordance for each). In contrast, 1 reviewer-identified episodes were 69.8% acidic, 76.9% upright, and limited to the distal esophagus. Using 5-reviewer concordance, designation of GERD evidence changed from automated analysis in 16%-19% of patients. Conclusions Acidic episodes with high proximal extent in the upright position and longer acid clearance times on pH-impedance studies have the highest concordance for identification by expert reviewers. Reflux episode identification may be influenced by reviewer opinion despite availability of established criteria. Name: 1-Phenylurea.

I found the field of Environmental Sciences & Ecology very interesting. Saw the article Improvement of pesticide removal in contaminated media using aqueous extracts from contaminated biopurification systems published in 2019.0.

Despite certain limitations, bioaugmentation enhances the efficiency of bioremediation systems. In this study, three aqueous extracts (APE, ACE and APE) from aged residual biomixtures in three biopurification systems (BPSs) exposed to pesticides at a pilot scale were found to improve pesticide removal. The addition of ACEs and AVEs to solutions containing the model compound diuron increased removal rates 6- and 17-fold, respectively, as compared to APEs. These extracts also increased the removal of the metabolite 3,4-dichloroaniline, while AVEs, in particular, were found to remove all pesticides within 9 days. Three metabolites less hazardous than 3,4-dichloroaniline were identified by SPME/GC/MS. AVEs, which also enhance linuron removal in liquid media, were found to increase diuron removal 6-fold in BPSs. We observed an increase in the relative abundance of taxa, such as Chloroflexi, Acidobacteria, Gemmatimonadetes, Firmicutes, Deinococcus-Thermus and especially Proteobacteria (10%), in AV biomixtures, as well as an enrichment of gamma-proteobacteria and the actinobacterial genus Dokdonella in AVEs with respect to initial noncontaminated IV biomixture. We demonstrate that extracts containing a pollutant-acclimatized microbiome could be used as part of a bioaugmentation strategy to improve the functioning of on-farm BPSs and contaminated systems.

A series of novel 2,4-disubstituted quinazolines were synthesized and evaluated for their anti-tumor activity against five human cancer cells (MDA-MB-231, MCF-7, PC-3, HGC-27 and MGC-803) using MIT assay. Among them, compound 9n showed the most potent cytotoxicity against breast cancer cells. Compound 9n also significantly inhibited the colony formation and migration of MDA-MB-231 and MCF-7 cells. Meanwhile, compound 9n induced cell cycle arrest at G1 phase and cell apoptosis, as well as increased accumulation of intracellular ROS. Furthermore, compound 9n exerted anti-tumor effects in vitro via decreasing the expression of anti-apoptotic protein Bcl-2 and increasing the pro-apoptotic protein Bax and p53. Mechanistically, compound 9n markedly decreased p-EGFR and p-PI3K expression, which revealed that compound 9n targeted breast cancer cells via interfering with EGFR-PI3K signaling pathway. Molecular docking suggested that compound 9n could indeed bind into the active pocket of EGFR. All the findings suggest that compound 9n might be a valuable lead compound for anti-tumor agents targeting breast cancer cells. (C) 2019 Elsevier Masson SAS. All rights reserved.

A new strategy is presented for enhancing the catalytic activity of cross-linked chitosan beads. More precisely, chitosan beads were cross linked with glutaraldehyde and then, vinyl functionalized. In the next step, the vinyl-functionalized beads were polymerized with the as-prepared 1-vinyl-3-butylimidazolium bromide to furnish polyionic liquid on beads. The resultant compositewas subsequently utilized as a metal-free catalyst for catalyzing some classic organic transformations, including Knoevenagel condensation reaction and syntheses of tetrahydrobenzo[b]pyrans and pyrano[2,3-d]pyrimidines in aqueous media under mild reaction conditions. It was found that the novel composite could efficiently promote all of the examined reactions to afford the corresponding products in high yields. Moreover, the catalyst exhibited high recyclability for all reactions. The comparative studies also approved that the activity of the composite was superior compared to cross-linked bead and polyionic liquid. (C) 2021 Elsevier B.V. All rights reserved.

A new series of 3-(quinazol-2-yl)-quinolines was synthesized by SNAr reaction from easily prepared 4-chloro-2-(2-chloroquinolin-3-yl)quinazolines and a range of phenols and thiophenol as nucleophiles. The AlCl3-mediated CC bond formation was also successfully exploited to introduce aryl and hereroaryl substituents on one or both heterocyclic units. These procedures afford efficient syntheses of polysubstituted 3-(quinazol-2-yl)-quinolines in few steps and high yields. Some of these polysubstituted 3-(quinazol-2-yl)-quinolines inhibit the human 20S proteasome. (C) 2020 Elsevier Ltd. All rights reserved.

Kinetics of thermostimulated luminescence (TSL) of poly(diphenylenephthalide) (PDPh) films has been studied using mathematical modelling and DFT approximation. TSL of PDPh-film was considered to be arising from irradiative deactivation of diphenylene (DP) fragment of polymer chain in excited state formed upon recombination of the spatial separated ion-radical pairs generated by photoexcitation. Two parallel monomolecular transformations leading to excited DP have been revealed: the first path is characterized by the activation parameters of the kinetic rate constant k1 which equal to Al ti 105 sec 1 and Eat ti 70 kJ mol(-1). This path may be interpreted in terms of mechanical relaxation theory by segmental polymer mobility as electron transfer (ET) from phthalide (Ph) anion-to DP cation-radical. The second channel is supposed to be consist of two consecutive ET from triarylmethyl anion-radical to phthalide neutral (A2 ti 1 sec 1, Ea2 ti 20 kJ mol(-1)), and then to DP cation-radical (A3 N 104 sec 1, E,3 N 40 kJ mol(-1)) of the polymer chain indicating y- and fl-relaxation, respectively. The revealed mechanistic steps and electron retention efficiency estimated in B97-2/6-311 + G(d,p) approximation for the most probable anion-radicals may point out the key role of domino quantum tunneling in transfer and recombination of charges in PDPh films.

For achieving a well-miscible and highly enhanced polyethylene/ultrahigh-molecular-weight polyethylene (PE/ UHMWPE) blend, which is an important blend for polyolefin materials with wide applications, tailored bonded interfacial intermolecular entanglement between the two phases was innovatively constructed via a facile reactive melt process through reaction between epoxy and carboxyl groups grafted onto polymer chains. The UHMWPE phase with obvious decreasing size and distribution was tightly embedded in a PE matrix, and the interfacial transition area increased dramatically, leading to forming a homogeneous and miscible blend. Meanwhile, the viscoelasticity and molecular entanglement density were improved remarkably, indicating an enhanced interfacial intermolecular diffusion, and a tight and robust dual network structure with covalent linkage and intermolecular entanglements was constructed in the blend. Obvious deformation with regular striation and many pulling-out UHMWPE fibrils were observed on an impact-fractured surface, and mechanical strength/toughness of the blend was remarkably enhanced. Furthermore, the wear rate and the friction coefficient were reduced significantly, and the worn surface presented smooth and flat features, confirming highly improved mechanical and tribological properties of the blend. This work provided a facile method to fabricate an enhanced PE/UHMWPE blend with application potential.

Chiral polyureas of cinchona alkaloids were synthesized via repetitive Mizoroki-Heck (MH) coupling reaction. The Pd-catalyzed polycondensation of cinchona urea dimers6and aromatic diiodide7afforded the chiral polyureas (P1-P4). The catalytic activity of the chiral polymers was subsequently investigated. The asymmetric Michael addition of ketoesters to nitroolefins was successfully catalyzed by the polymeric organocatalysts (P1-P4) to give the corresponding Michael adducts with high catalytic activities and excellent enantionselectivities (up to >99% ee). The polymeric catalysts were insoluble in commonly used organic solvents. They were easily recovered and reused several times without any loss of the catalytic activity.
