An unusual phenomenon occurred in new display cases at the Rijksmuseum four months after their installation in April 2013. White deposits were visible on glass windows, silicone door gaskets, black structural adhesive seals, and on works of art. The works of art most affected by these deposits were bronze sculptures, wooden and waxed objects, tempera, and oil paintings. In this study the deposits were chemically characterised using (pyrolysis-)gas chromatography-mass spectrometry ((Py-)GC-MS), mu-Raman spectroscopy (mu-Raman), ion chromatography (IC), and scanning electron microscopy combined with energy dispersive X-ray spectroscopy (SEM-EDX). Five chemically different crystalline deposits were found. They were identified as organic salts of the base 2,2,6,6-tetramethyl-4-piperidinol (TMP-ol), a secondary amine, and five different carboxylic acids. It was found that TMP-ol, which is part of the UV-light stabiliser Tinuvin-770, emitted from the structural adhesive Terostat-9220. Terostat-9220 was used in large quantities in the display cases to adhere glass windows to metal parts. The carboxylic acids derived from both construction materials used to build the cases and from conservation materials present on the exhibited works of art. The carboxylic acids involved were 2,4-dichlorobenzoic acid, formic acid, methacrylic acid, palmitic acid, and an unknown carboxylic acid, respectively emitted from peroxide-cured silicone gaskets, panels of medium-density fibreboard (MDF), UV-adhesive, beeswax containing products, and from an unknown acidic conservation product or binding medium. The identification of the crystalline deposits was supported by their syntheses in the laboratory. Since 2013, similar deposits have been observed in a number of museum collections worldwide. A treatment for preventing further growth of the deposits was developed and applied in the Rijksmuseum showcases.

Text. A general method for the synthesis of structural diversity and complexity of azepines from aldimine esters and beta ‘-acetoxy allenoates is reported. Under phosphine catalysis, a [4+3] cycloaddition for the formation of 1,3-dihydro-2H-azepine-2,2,4-tricarboxylates was achieved with broad substrate scope under mild reactions. A switchable process was given and a variety of important 2,3-dihydrochromeno[4,3-b]azepin-6(1H)-ones were selectively formed when the reaction was performed in the presence of Cs2CO3 and PPh3, which involved an intramolecular ester group migration and subsequent lactonization of 1,3-dihydro-2H-azepine-2,2,4-tricarboxylates. Besides easy handle process, high synthetic value of resulting products, it is worth to note that this work showed the novel example of 1,5-ethoxycarbonyl migration.

Cancer is a leading cause of death all over the world. HGF/MET signaling pathway is involved in many cancers and its inhibition has great potential as an effective therapeutic intervention. A series of 1H-pyrrolo [2,3-b]pyridine derivatives has recently been identified with cytotoxic activity, and most of them exhibited considerable potencies with IC50 values under 10 mu M. The present study was carried out with the specific aim to shed light upon the quantitative structure activity relationship (QSAR) to design and predict the activity of new potent inhibitors using molecular fingerprints and some 2D and 3D descriptors. The built model was statistically significant in terms of R-2 = 0.90 and R-pred(2) = 0.91 values. Fingerprint PubchemFP759 (1-chloro-2-methylbenzene) was the most effective fragment in the biological activity and just appeared in the most active compound 7j with a pIC(50) value of 8.0. A similarity search study was applied based on compounds 7c and 17e, with reported inhibitory activity against c-Met kinase, which showed that also other compounds could possess similar effects against c-Met enzyme. The most promising compound 7g-cl was subjected to docking and molecular dynamics simulation. Two hydrogen bonds between Lys1110, Met1160, and 7g-cl were stable during the equilibrium time range. The suggested modifications might be considered in future studies to design more efficient anticancer agents.

Pyrazinamide is an important first-line drug used in shortening TB therapy. In our current work, a series of novel substituted-N-(6-(4-(pyrazine-2-carbonyl)piperazine/homopiperazine-1-yl)pyridin-3-yl)benzamide derivatives were designed, synthesized, and evaluated for their anti-tubercular activity against Mycobacterium tuberculosis H37Ra. Among the tested compounds, five compounds (6a, 6e, 6h, 6j and 6k) from Series-I and one compound (7e) from Series-II exhibited significant activity against Mycobacterium tuberculosis H37Ra with 50% inhibitory concentrations (IC50) ranging from 1.35 to 2.18 mu M. To evaluate the efficacy of these compounds, we examined their IC90 values. Five of the most active compounds were found to be more active with IC(90)s ranging from 3.73 to 4.00 mu M and one compound (6e) showed an IC90 of 40.32 mu M. Moreover, single crystals were developed for 6d, 6f and 6n. In addition, most active compounds were evaluated for their cytotoxicity on HEK-293 (human embryonic kidney) cells. Our results indicate that the compounds are nontoxic to human cells. The molecular interactions of the derivatised conjugates in docking studies reveal their suitability for further development.

A series of novel N-phenylbenzamide-4-methylamine acridine derivatives were designed and synthesized based initially on the structure of amsacrine (m-AMSA). Molecular docking suggested that the representative compound 9a had affinity for binding DNA topoisomerase (Topo) II, which was comparable with that of m-AMSA, and furthermore that 9a could have preferential interactions with Topo I. After synthesis of 9a and analogues 9b-9f, these were all tested in vitro and the synthesized compounds displayed potent antiproliferative activity against three different cancer cell lines (K562, CCRF-CEM and U937). Among them, compounds 9b, 9c and 9d exhibiting the highest activity with IC50 value ranging from 0.82 to 0.91 mu M against CCRF-CEM cells. In addition, 9b and 9d also showed high antiproliferative activity against U937 cells, with IC50 values of 0.33 and 0.23 mu M, respectively. The pharmacological mechanistic studies of these compounds were evaluated by Topo I/II inhibition, western blot assay and cell apoptosis detection. In summary, 9b effectively inhibited the activity of Topo I/II and induced DNA damage in CCRF-CEM cells and, moreover, significantly induced cell apoptosis in a concentration-dependent manner. These observations provide new information and guidance for the structural optimization of more novel acridine derivatives.

Objectives: To evaluate the performance of a high-throughput research assay for HIV drug resistance testing based on whole genome next-generation sequencing (NGS) that also quantifies HIV viral Load. Methods: Plasma samples (n = 145) were obtained from HIV-positive MSM (HPTN 078). Samples were analysed using clinical assays (the ViroSeq HIV-1 Genotyping System and the Abbott RealTime HIV-1 Viral Load assay) and a research assay based on whole-genome NGS (veSEQ-HIV). Results: HIV protease and reverse transcriptase sequences (n =142) and integrase sequences (n =138) were obtained using ViroSeq. Sequences from all three regions were obtained for 100 (70.4%) of the 142 samples using veSEQ-HIV; results were obtained more frequently for samples with higher viral Loads (93.5% for 93 samples with >5000 copies/mL; 50.0% for 26 samples with 1000-5000 copies/mL; 0% for 23 samples with <1000 copies/mL). For samples with results from both methods, drug resistance mutations (DRMs) were detected in 33 samples using ViroSeq and 42 samples using veSEQ-HIV (detection threshold: 5.0%). Overall, 146 major DRMs were detected; 107 were detected by both methods, 37 were detected by veSEQ-HIV only (frequency range: 5.0%-30.6%) and two were detected by ViroSeq only. HIV viral Loads estimated by veSEQ-HIV strongly correlated with results from the Abbott RealTime Viral Load assay (R-2 = 0.85; n = 142). Conclusions: The NGS-based veSEQ-HIV method provided results for most samples with higher viral Loads, was accurate for detecting major DRMs, and detected mutations at Lower Levels compared with a method based on population sequencing. The veSEQ-HIV method also provided HIV viral Load data. Recommanded Product: 2,6-Dichlorobenzoic acid.

A divergent approach has been successfully developed for the synthesis of N-1,2,4-oxadiazole substituted sulfoximines starting from N-cyano sulfoximines. This method has a wide degree of substrate scope that includes aryl, heteroaryl, alkyl, fluoroalkyl and saturated heterocyclic compounds. Excellent functional group tolerability was also observed. Extension of this methodology to nucleosides, amino acids and dipeptides was found to be successful. A gram scale reaction was also established. The major part of this method is metal free and the utility of environmentally friendly solvents such as 2-methyl THF and ionic liquids is an added advantage.

Chloroaluminate ionic liquids (ILs) have been immensely used as homogeneous catalyst in Friedel-Crafts reaction. We have recently synthesized chloroaluminate ILs by reacting aluminium chloride with a hydrophobic neutral ligand i.e. tributylamine (TBA:AlCl3). The current study elaborates on the investigations of the composition of the ionic liquids at various stages of their formation. The ionic liquids were synthesized using various mole ratios of tributyl amine and aluminium chloride in range of 1:1 to 1:2.3, in presence of an aromatic solvent in a one pot reaction. Various characterization techniques like Mass spectrometry, Al-27 Nuclear Magnetic Resonance, P-31 Nuclear Magnetic Resonance and Fourier Transform Infrared spectroscopy were used to elucidate the formation of various moieties of the TBA:AlCl3 Ionic Liquid. This study also elaborates on the investigations of the cationic and anionic moieties and their structure-property relationship for various applications. Various Friedel-Crafts reaction of industrial importance were performed using the ionic liquid having (Al2Cl7)(-) moiety to assess its performance and compared with conventional processes. The synthesized products were characterised by sophisticated analytical techniques like H-1 NMR, C-13 NMR, FTIR, GC-MS, GC-FID, to name a few. This class of ionic liquids also have importance in various electrochemical applications like aluminium deposition and aluminium batteries. (C) 2020 Elsevier B.V. All rights reserved.
