This article presents a detailed comprehensive investigation of the ortho fluoro- and chloro- substituted benzoic acids both, as isolated molecules and in the crystalline phase. Quantum chemical calculations performed within the density functional theory (DFT) formalism are used to investigate the potential energy landscapes of the molecules, taking into special consideration the effects of the interactions between the carboxylic group and the ortho halogen substituents, as well as the nature of these later on the structure and properties of the investigated systems. The structures of the relevant conformers of the molecules are discussed in comparative terms, and used to rationalize experimental data obtained for the compounds in the gas phase and isolated in low-temperature inert matrices. The UV-induced photofragmentation reactions of two of the compounds isolated in cryogenic inert matrices were studied as illustrative cases. The structures of the crystals reported previously in the literature are revisited and discussed also in a comparative basis. Particular emphasis is given to the analysis of the intermolecular interactions in the different crystals, using Hirshfeld surface analysis, the CE-B3LYP energy decomposition model and the HOMA index, and to their correlation with thermodynamic data.

We describe a new catalytic strategy to transcend the energetic limitations of visible light by electrochemically priming a photocatalyst prior to excitation. This new catalytic system is able to productively engage aryl chlorides with reduction potentials hundreds of millivolts beyond the potential of Na-0 in productive radical coupling reactions. The aryl radicals produced via this strategy can be leveraged for both carbon-carbon and carbon-heteroatom bond-forming reactions. Through direct comparison, we illustrate the reactivity and selectivity advantages of this approach relative to electrolysis and photoredox catalysis.

Background:Licensed therapies for nonalcoholic fatty liver disease (NAFLD) do not yet exist, but clinical trials are testing treatment options. Inclusion criteria often require liver biopsy showing fibrosis (F2/3) or cirrhosis (F4) and nonalcoholic steatohepatitis (NASH). However, histological criteria pose a serious obstacle for recruitment. Aims:Characterize the relevance of liver biopsies in the selection of patients with NAFLD. Methods:Patients between 2013 and 2018 with the ICD-10 code K76.0 were analyzed. Fibrosis was defined by the NASH clinical research network (CRN) fibrosis staging system, NASH by a NAFLD activity score (NAS) >= 4. Predictive factors were determined by logistic regression. Results:Liver biopsy was performed in 87/638 (13.6%) patients (49% female, age 52.5 +/- 14.0, BMI 30.4 +/- 5.9 kg/m(2)). Fibrosis stage F0/F1/F2/F3/F4 was observed inN = 7/47/7/17/9, an NAS >= 4 inN = 27. Fibrosis stage F2/F3 and F4 along with NAS >= 4 was found in 1.7% and 0.5% of cases. Liver stiffness measurement, LSM (OR 2.3 per doubling of value; CI 1.3-4.4,p = .005) and FIB-4 (OR 2.3 per doubling of value; CI 1.2-4.4,p = .012) were significant predictors for fibrosis >= F2. Predictive factors for NASH were not identified. Conclusion:The biopsy rate in NAFLD patients is low and fibrosis >= F2 along with NAS >= 4 only present in a few cases. Transient elastography and FIB-4 are useful to select patients at risk for fibrosis for liver biopsy.

Binary azeotropes, which contain two chemical constituents, are very common in industry. Understanding azeotropic properties is crucial for effectively separating binary azeotropes. Experimental and theoretical approaches such as ab initio have been used to estimate mixture properties but they are costly and time-consuming. The quantitative structure-property relationship (QSPR) model is a viable alternative approach. The most challenging problem in the QSPR study of mixtures is the computation of numerical descriptors to characterize a mixture. In this study, a series of twenty-two formulas were proposed to derive mixture descriptors from the molecular descriptors of the individual pure compounds. The derived mixture descriptors were employed to establish QSPR models to predict the boiling point of binary azeotropic mixtures. The QSPR model developed was found to be the best with R-train(ing)2 and R-test(2) of 0.92 and 0.90 on the basis of a novel proposed formula, in which some coefficients related to the potential energy contribution were used. Mean absolute errors (MAEs) associated with training and test sets were computed as 9.90 and 10.61, respectively. Twelve out of the twenty-two mixture descriptors resulted in the QSPR models with reasonable statistical qualities and, therefore, were taken into account in the production of an ensemble model via a simple averaging strategy. This caused to improve statistical quality of the final QSPR model. (C) 2019 Published by Elsevier B.V.

To develop novel therapeutic agents with anticancer activities, two series of novel 2,4-bismorpholinyl-thieno [3,2-d]pyrimidine and 2-morpholinothieno[3,2-d]pyrimidinone derivatives were designed, synthesized and evaluated for their biological activities. Among them, compound A(12) showed the most potent antitumor activities against HCT116, PC-3, MCF-7, A549 and MDA-MB-231 cell lines with IC50 values of 3.24 mu M, 14.37 mu M, 7.39 mu M, 7.10 mu M, and 16.85 mu M, respectively. Further explorations in bioactivity were conducted to clarify the anticancer mechanism of compound A(12). The results showed that compound A(12) obviously inhibited the proliferation of A549 cell lines and decreased mitochondrial membrane potential, which led to the apoptosis of cancer cells and suppressed the migration of tumor cells.

Quality Control of 1-Chloro-2-methylbenzene. I found the field of Environmental Sciences & Ecology very interesting. Saw the article Emission characteristics and associated health risk assessment of volatile organic compounds from a typical coking wastewater treatment plant published in 2019.0, Reprint Addresses Wei, CH (corresponding author), South China Univ Technol, Sch Environm & Energy, Guangzhou 510006, Guangdong, Peoples R China.; Yan, B (corresponding author), South China Normal Univ, Environm Res Inst, Guangzhou 510031, Guangdong, Peoples R China..

Coking wastewater is a typical industrial wastewater and contains a number of toxic and harmful organic pollutants which threaten human health. However, emission of volatile organic compounds (VOCs) from coking wastewater treatment plants (WWTPs) is rarely studied. Here, the emission characteristics of VOCs were investigated in a full-scale coking WWTP composed of an anaerobic-oxic-oxic (A-O-1-O-2) treatment system. Furthermore, the potential health risks were assessed in this study. VOC emission rates were estimated at each unit of the coking WWTP and the influencing factors of e missions were discussed. Seventeen VOCs were identified in the air phase by gas chromatography-mass spectrometry combined with Tenax adsorption-thermal desorption method: benzene, toluene, and xylenes were predominant, and the concentration of total VOCs decreased gradually from the raw water tank (857.86 +/- 131.30 mu g m(-3)) to the effluent tank (28.56 +/- 3.96 mu g m(-3)). The total VOC emission rate from all units was 1773.42 g d(-1), corresponding to an annual emission of 0.65 tons year(-1). Since the treatment capacity of this coking WWTP was about 1500 m(3)d(-1), it was estimated that 1.18 g of VOCs are emitted during the treatment of 1 m(3) wastewater. Influencing factors of VOC emission mainly include the background concentration of VOCs in wastewater, operational parameters of the treatment processes, and physicochemical properties of VOCs. The carcinogenic risk of VOCs for workers in this coking WWTP ranged from 3.0 x 10(-5) to 7.8 x 10(-4), which exceeded an acceptable level (1.0 x 10(-6)). The non-carcinogenic risk hazard ratio of benzene exceeded 1, indicating that benzene has an obvious non-carcinogenic risk. Understanding VOCs emission characteristic and emission rates can help to identify the adverse effects of coking WWTPs on human health and provide relevant information for policy-making.

Direct conversion of cheap methylarenes to benzylic amines, which are essential structural units of important drugs, is of great significance. However, the known methodologies suffer from the requirement of noble metal catalysts, heavy metal residues or strong oxidants. Herein, the first biocompatible iron-catalyzed benzylic C (sp(3))-H amination of methylarenes with N-fluorobenzenesulfonimide is described. The reactions of methylarenes bearing electron-donating groups and electron-withdrawing groups ran smoothly under ligand and additional oxidant free conditions. Both toluene derivatives and 8-methylquinoline can be aminated by the same iron catalyst.
