The oxidation of a series of alkylaromatic compounds with H2O2 catalyzed by an imine-based non-heme iron complex prepared in situ by reaction of 2-picolylaldehyde, 2-picolylamine, and Fe(OTf)(2) in a 2 : 2 : 1 ratio leads to a marked chemoselectivity for aromatic ring hydroxylation over side-chain oxidation. This selectivity is herein investigated in detail. Side-chain/ring oxygenated product ratio was found to increase upon decreasing the bond dissociation energy (BDE) of the benzylic C-H bond in line with expectation. Evidence for competitive reactions leading either to aromatic hydroxylation via electrophilic aromatic substitution or side-chain oxidation via benzylic hydrogen atom abstraction, promoted by a metal-based oxidant, has been provided by kinetic isotope effect analysis.

Under the acyclic diene metathesis (ADMET) reaction condition, the C3-vinyl groups of cinchona alkaloids readily react with each other to form a C-C bond. A novel type of cinchona alkaloid polymers was synthesized from dimeric cinchona squaramides using the Hoveyda-Grubbs’ second-generation catalysts (HG(2)) by means of ADMET reaction. The chiral polymers, containing cinchona squaramide moieties in their main chains, were subsequently employed as catalysts for the enantioselective Michael reaction to give the corresponding chiral adducts in high yields with excellent enantioselectivity and diastereoselectivity. Both enantiomers from the asymmetric Michael reaction were distinctively prepared while using the polymeric catalysts, possessing pseudoenantiomeric structures. The catalysts were readily recovered from the reaction mixture and recycled several times due to the insolubility of the cinchona-based squaramide polymers.

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.

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.

Sulfate radical (SO4 center dot(-)) and hydroxyl radical (center dot OH) generated from persulfate or peroxymonosulfate in AOPs have been widely used in contaminant degradation. Anthracene (ANT) can be decomposed by SO4 center dot(-) and center dot OH. The processes of ANT decomposition were investigated using theoretical calculations in this paper. The initiation reactions of ANT, anthrone, anthraquinone (ATQ) and 1-hydroxylanthraquinone (1-hATQ) by two radicals are studied. The highest free energy barriers of initiation reactions are 22.30 kcal mol(-1) in ATQ + SO4 center dot(-) reaction and 6.84 kcal mol(-1) in ATQ + center dot OH reaction. Comparing the rate constants of initiation reaction through the two radicals at 273-373 K, it can be concluded that SO4 center dot(-) and center dot OH both play important roles on the initiation of ANT and anthrone at lower pH. For ATQ and 1-hATQ, center dot OH is more important than SO4 center dot(-) in the initiation process, which indicates that the indirect influence of SO4 center dot(-) are more significant in the degradation processes of ATQ and 1-hATQ. This study provides theoretical confirmations for the mechanisms of reactions of ANT with SO4 center dot(-) and center dot OH, and evaluates the importance of SO4 center dot(-) and center dot OH according to the reaction rates. The work can give more insight into the degradation of PAHs by radicals.

BACKGROUND Ara h 1 is a major food allergen in peanuts. Recently, many studies have revealed that the Maillard reaction (MR) affects the allergenicity of food proteins. RESULTS To investigate the influence of the MR on the allergenicity of Ara h 1, R-Ara h 1 was processed with glucose in dry heating conditions for different periods. The extent of the MR was assessed by four methods. The changes in secondary and tertiary structures were characterized through spectroscopy assays. Advanced glycation end products (AGE) structures were identified by protein sample dry heating for 60 min, indicating the formation of AGE-Ara h 1. Simulated gastric fluid (SGF) digestion analysis showed that AGE-Ara h 1 has higher resistance to peptic digestion than R-Ara h 1. The BALB/c mouse model was also utilized to explore the effect of the MR on the allergenicity of Ara h 1, and the results showed that the Th2-type cytokines, antibodies, and histamine content increased, and there was a greater degree of degranulation of rat basophilic leukemia (RBL) cells in the AGE-Ara h 1 group compared with the R-Ara h 1 group. CONCLUSION During the process of dry heating, proteins participated in the MR with changes in secondary and tertiary structures. The condition applying a temperature of 100 degrees C for 60 min caused the formation of AGE-Ara h 1. Simulated gastric fluid digestion analysis showed that AGE-Ara h 1 had a greater resistance to peptic digestion than R-Ara h 1. The BALB/c mouse model showed that AGE-Ara h 1 had more allergenicity, indicating that the MR could enhance the allergenicity of Ara h 1. (c) 2020 Society of Chemical Industry

An efficient intramolecular radical cyclization reaction via photoredox catalysis was developed for the synthesis of dibenzocycloketone derivatives using methylene blue as a photosensitizer. This strategy could be widely used to synthesize large heterocycles due to the unique reactivity of phosphoranyl radicals formed by a polar/SET crossover between an aromatic carboxylic acid and a phosphine radical cation. Attractive features of this process include generation of an acyl radical by an inexpensive and metal-free photocatalyst, which effectively undergoes a cyclization process.

A new aromatic diamine, 10,10-bis[4-(4-aminophenoxy)phenyl]-9(10H)-anthrone (BAPA) has been synthesized from anthrone via three-step procedure. Direct phosphorylation polycondensation of BAPA with various aromatic dicarboxylic acids produced a series of cardo poly(ether amide)s with inherent viscosities of 0.97-1.29 dL g(-1). All the polymers were readily soluble in polar solvents such as N-methyl-2-pyrrolidone, N, N-dimethylacetamide (DMAc), and pyridine at room temperature, and afforded transparent, strong, and flexible films upon casting from DMAc solvent. The resulting poly(ether amide)s had glass transition temperatures of 254-316 degrees C, 10% weight loss temperatures of 495-524 degrees C, and char yields of 55-70% at 800 degrees C in nitrogen. These polymers were amorphous and their films exhibited tensile strengths of 81.6-104.7 MPa, tensile moduli of 1.8-2.4 GPa, and elongations at break of 8-15%.

Lymphomas (cancers of the lymphatic system) account for 12% of malignant diseases worldwide. Burkitt’s lymphoma (BL) is a rare form of non-Hodgkin’s lymphoma in which the cancer starts in the immune B-cells. We report the synthesis and preliminary studies on the antiproliferative activity of a library of 9,10-dihydro-9,10-ethanoanthracene based compounds structurally related to the antidepressant drug maprotiline against BL cell lines MUTU-1 and DG-75. Structural modifications were achieved by Diels-Alder reaction of the core 9-(2-nitrovinyl)anthracene with number of dienophiles including maleic anhydride, maleimides, acrylonitrile and benzyne. The antiproliferative activity of these compounds was evaluated in BL cell lines EBV- MUTU-1 and EBV+ DG-75 (chemoresistant). The most potent compounds 13j, 15, 16a, 16b, 16c, 16d and 19a displayed IC50 values in the range 0.17-0.38 mu M against the BL cell line EBV- MUTU-1 and IC50 values in the range 0.45-0.78 mu M against the chemoresistant BL cell line EBV+ DG-75. Compounds 15, 16b and 16c demonstrated potent ROS dependent apoptotic effects on the BL cell lines which were superior to the control drug taxol and showed minimal cytotoxicity to peripheral blood mononuclear cells (PBMCs). The results suggest that this class of compounds merits further investigation as antiproliferative agents for BL.

Organic pollutants associated with diesel exhaust particles (DEP), such as polycyclic aromatic hydrocarbons (PAHs) and their derivatives, may negatively impact human health. However, a comprehensive overview of their effects on endocrine nuclear receptor activities is still missing. Here, we evaluated the effects of extracts and chromatographic fractions (fractionated according to increasing polarity) of two standard reference materials derived from distinct types of diesel engines (SRM 2975, SRM 1650b), on activation of androgen receptor (AR), estrogen receptor alpha (ER alpha), peroxisome proliferator-activated receptor gamma (PPAR gamma), glucocorticoid receptor (GR) and thyroid receptor alpha (TR alpha), using human cell-based reporter gene assays. Neither DEP standard modulated AR or GR activities. Crude extracts and fractions of SRM 1650b and SRM 2975 suppressed ER alpha-mediated activity in the ER-CALUX (TM) assay; however, this effect could be partly linked to their cytotoxicity in this cell line. We observed that only SRM 2975 extract and its fractions were partial PPAR gamma inducers, while SRM 1650b extract was not active towards this receptor. Importantly, we found that both extracts and polar fractions of SRM activated TR alpha and significantly potentiated the activity of endogenous TR alpha ligand, triiodothyronine. Based on a detailed chemical analysis of both extracts and their polar fractions, we identified several oxygenated PAH derivatives, that were present at relatively high levels in the analyzed DEP standards, including 3-nitrobenzanthrone (3-NBA), anthracene-9,10-dione, phenanthrene-9,10-dione. 9H-fluoren-9-one or benzo[a] anthracene-7,12-dione, to activate TR alpha activity. Nevertheless, these compounds provided only a minor contribution to the overall TR alpha activity identified in polar fractions. This suggests that yet unidentified polar polyaromatic compounds associated with DEP may, apart from their known impact on the aryl hydrocarbon receptor or steroid signaling, deregulate activities of additional nuclear receptors, in particular of TR alpha. This illustrates the need to better characterize endocrine disrupting activities of DEP. (C) 2019 Elsevier B.V. All rights reserved.
