Chitosan decorated copper nanoparticles (CS/CuNPs) catalysts were synthesized via reduction methods utilizing green protocol. The CS/CuNPs hybrid catalysts were tested for the synthesis of quinoline derivatives utilizing one-pot multicomponent reaction (MCR) under ultrasonic irradiation. The optimized CS/CuNPs catalyst that provided good conversion reaction yield and high turnover frequency (TOF) was characterized using Fourier transform infrared (FTIR), thermogravimetric analyses (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM) and X-ray photoelectron spectroscopy (XPS) techniques. Generalization of the scope of the proposed catalytic process was studied using different aldehydes. Excellent products yield and high TOF in even shorter reaction time (similar to 5 min) was attained. Recyclability performance of the catalyst over five times re-use without detectable loss in product yield was recorded. The current method is green process utilizing environmentally benign catalyst and considered to be promising sustainable protocol for the synthesis of fine chemicals.

E-cigarettes have become very popular, a trend that has been stimulated by the wide variety of available e-liquid flavours. Considering the large number of e-liquid flavours (>7000), there is an urgent need to establish a screening strategy to prioritize the flavouring substances of highest concern for human health. In the present study, a prioritization strategy combining analytical screening, in silico tools and literature data was developed to identify potentially genotoxic e-liquid flavourings. Based on the analysis of 129 e-liquids collected on the Belgian market, 60 flavourings with positive in silico predictions for genotoxicity were identified. By using literature data, genotoxicity was excluded for 33 of them whereas for 5, i.e. estragole, safrole, 2-furylmethylketon, 2,5-dimethyl-4-hydroxyl-3(2H)-furanone and transhexanal, there was a clear concern for in vivo genotoxicity. A selection of 4 out of the remaining 22 flavourings was tested in two in vitro genotoxicity assays. Three out of the four tested flavourings induced gene mutations and chromosome damage in vitro, whereas equivocal results were obtained for the fourth compound. Thus, although there is a legislative framework which excludes the use of CMR compounds in e-liquids, flavourings of genotoxic concern are present and might pose a health risk for e-cigarette users.

Bridged biaryl atropisomers are important units in bioactive molecules. A synthesis of lactone-bridged biaryl atropisomers was realized by a Cu-catalyzed asymmetric ring-opening/acyoxylation of cyclic diaryliodoniums, followed by a palladium-catalyzed diastereoselective cyclization. It was found that a catalytic amount of Cu(OTf)(2) served as an additive to promote the palladium-catalyzed Heck cyclization.

The present investigation aims to synthesize and explore the influence of pyridine and pyran derivatives on the API X-65 steel corrosion in a 6 M H2SO4 solution. The compound was examined at different concentrations to optimized the best concentration for the corrosion inhibition effect, weight loss measurements, potentiodynamic polarization measurement (PDP), electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM) and theoretical methods were used to evaluating the inhibition efficiency. The obtained adsorption data achieved the model of Langmuir isotherm. The pyridine derivatives showed higher inhibition than pyran derivatives. The PDP tests proposed that pyridine and pyran derivatives are mixed-type inhibitors. The EIS parameters demonstrate that the double-layer capacitance (C-dl) decreases with the increase of inhibitor concentration, which implies a reduces dielectric constant. It was observed from experimental data that the inhibition efficiency reached 92.7%, 89.1, 94.7, and 85.2% for concentration 2.66 x 10(-3)M of I, II, III and IV, respectively indicating the inhibition order is III > I > II > IV. The parameters derived from the theoretical quantum chemical calculations were found adequately correlated with the obtained experimental results.

One of the fundamental and highly valuable transformations in organic chemistry is the nucleophilic substitution of alcohols. Traditionally, these reactions require strategies that employ stoichiometric hazardous reagents and are associated with difficulty in purification of the by-products. To overcome these challenges, here, we report a simple route toward the diverse conversion of alcohols via an S(N)2 pathway, in which blue light-promoted iodination is used to form alkyl iodide intermediates from simple unreactive alcohols. The scope of the process tolerates a range of nucleophiles to construct C-N, C-O, C-S, and C-C bonds. Furthermore, we also demonstrate that this method can be used for the preparation and late-stage functionalization of pharmaceuticals, as highlighted by the syntheses of thiocarlide, butoxycaine, and pramoxine.

In the present work, a new type of bio-based benzoxazines were prepared by using aniline, N, N-dimethyl amino propyl amine (DMAPA) and caprolactam modified DMAPA with eugenol. The benzoxazines resulted were characterized for their molecular structure by Fourier transform infrared and nuclear magnetic resonance spectroscopy. The polymerization process of benzoxazines and their thermal behavior were studied by differential scanning calorimetry and thermogravimetric analysis, respectively. Moreover, the effect of chemical blending of the synthesized benzoxazines with conventional benzoxazines [bisphenol A benzoxazine (BPAb) and bisphenol F benzoxazine (BPFb)] and bismaleimide was studied to bring down the polymerization temperature by creating supplementary potential sites for polymerization. Furthermore, to reduce the polymerization temperature, the benzoxazines synthesized in the present study were partially incorporated with 10 wt % of catalysts (4-hydroxy phenylmaleimide, 4-amino phenol, and 4-hydroxy acetophenone). The graphene reinforced polybenzoxazine composites were also prepared by incorporating varying weight percentages (1, 3, 5, 7, and 10 wt %) of graphene oxide to obtain hybrid nanocomposites. From the results obtained, it was observed that the polymerization temperature (T-p) was significantly reduced (more than 31 degrees C) in both the cases of blends of conventional BPAb and BPFb. It was also observed that the values of the dielectric constant of graphene reinforced hybrid composites are significantly enhanced. (c) 2018 Wiley Periodicals, Inc. J. Appl. Polym.

The quality of the Dniester River Basin has been seriously impacted by the chemicals released by agriculture, industry, and wastewater discharges. To assess its current chemical pollution status, a transboundary monitoring campaign was conducted in May 2019. Thirteen surface water, 13 sediment, and three biota samples were collected and analyzed using generic sample preparation methods for the determination of organic substances by liquid chromatography high-resolution mass spectrometry (LC-HRMS) and metals by inductively coupled plasma mass spectrometry (ICP-MS). Wide-scope target and suspect screening resulted in detection of Water Framework Directive (WFD) priority substances and emerging contaminants, whereas the raw data were stored in NORMAN Digital Sample Freezing Platform (DSFP) for future retrospective screening. Furthermore, risk assessment was performed to prioritize detected substances and propose a draft list of river basin-specific pollutants. All studied metals (As, Hg, Zn, Cu, Cr, Cd, Pb, Ni) were detected in the surface water and sediments. In total, 139 organic contaminants belonging to various chemical classes (pesticides, pharmaceuticals, drugs of abuse, stimulants, sweeteners, industrial chemicals, and their transformation products) were detected. The highest cumulative concentration of contaminants was observed in surface water from the Byk River, a tributary of the Dniester (Moldova). Concentrations of WFD priority substances diuron and mercury and EU Watch List neonicotinoid compounds imidacloprid and thiamethoxam exceeded their environmental quality standards (EQS), whereas concentrations of 23 emerging substances exceeded their predicted no-effect concentration (PNEC) at minimum one site. Emerging contaminants telmisartan, metolachlor, terbuthylazine, and 4-acetamidoantipyrine were prioritized as potential river basin-specific pollutants. Graphical abstract

Microtubules are highly dynamic polymers composed of alpha- and beta-tubulin proteins that have been shown to be potential therapeutic targets for the development of anticancer drugs. Currently, a wide variety of chemically diverse agents that bind to beta-tubulin have been reported. Nocodazole (NZ) and colchicine (COL) are well-known tubulin-depolymerizing agents that have close binding sites in the beta-tubulin. In this study, we designed and synthesized a set of nine 2,4-diaminoquinazoline derivatives that could occupy both NZ and COL binding sites. The synthesized compounds were evaluated for their antiproliferative activities against five cancer cell lines (PC-3, HCT-15, MCF-7, MDA-MB-231, and SK-LU-1), a noncancerous one (COS-7), and peripheral blood mononuclear cells (PBMC). The effect of compounds4 eand4 ion tubulin organization and polymerization was analyzed on the SK-LU-1 cell line by indirect immunofluorescence, western blotting, and tubulin polymerization assays. Our results demonstrated that both compounds exert their antiproliferative activity by inhibiting tubulin polymerization. Finally, a possible binding pose of4 iin the NZ/COL binding site was determined by using molecular docking and molecular dynamics (MD) approaches. To our knowledge, this is the first report of non-N-substituted 2,4-diaminoquinazoline derivatives with the ability to inhibit tubulin polymerization.
