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.

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.

In this paper, synthesized Fe3O4 nanoparticles applied as catalyst in photodegradation of Direct Red 23 (DR23) dye using photo-Fenton process in aqueous solution. The Fe3O4 nanoparticles were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Design of experiments (DOE) based on Taguchi approach was used. Analysis the response of each experiment was based Signal to Noise (S/N) ratio was calculated. The effective parameters for the degradation of dye were determined and optimized using Taguchi (L-9 (3(4))) orthogonal array experimental design method with four factors having three levels for each factor. The Taguchi approach showed that pH 3 (level 1), catalyst amount = 25 mg/L (level 2), H2O2 concentration = 15 ppm (level 3), and temperature = 35 degrees C (level 3) was optimum conditions for this process. The factor most influencing the process was determined using analysis of variance (ANOVA) method. The most significant factor in this process was pH. The interaction between pH x catalyst amount was the most influencing interaction. The percent (p (%)) of each factor on the degradation of dye was found to be in the following the order: pH (50.306%), catalyst amount (6.887%), H2O2 concentration (39.272%), and temperature (3.456%). The percentage contribution of factors in this process was found to be in the following the order: pH (0.332), catalyst amount (0.101), H2O2 concentration (0.291), and temperature (0.082). So first order reaction with k = 0.0472 min(-1) was observed for the photocatalytic degradation reaction.

The present study reports on the degradation of chlorinated benzoic acids (CBAs), commonly present in the environment as pollutants, by a hydrodehalogenation reaction utilizing the Raney Al-Ni alloy (50:50 wt% Al:Ni). The hydrodehalogenation reaction using the Raney Al-Ni alloy has already been proven as an efficient tool for fast and efficient degradation of halogenated persistent organic pollutants (POPs). Herein, the nano-structured Raney Al-Ni alloy was prepared by an alternative mechano-thermal approach starting from pure elements in a form of powders. The prepared alloy was characterized by X-ray diffractometry, scanning electron microscopy, particle size distribution, and active surface area analyses. The properties of the material were compared with a commercial sample of the same alloy prepared by the atomization process. The activity of the synthesized alloy was evaluated as removal efficiency and a rate of dehalogenation of three different CBAs – 2-chlorobenzoic acid, 2,6-dichlorobenzoic acid, and 2,3,6-trichlorobenzoic acid (trysben); used in the past as an herbicide. Dehalogenation of all three tested CBAs yielded benzoic acid as the only product and followed the first-order reaction kinetics. Compared to the commercially available alloy, enhanced kinetics of CBAs removal was achieved, owing to the solid-state properties of the mechano-thermally prepared alloy.

Structural modifications of nicotinamide, a form of vitamin B3, gave rise to a series of compounds (8aa-8ce) that exhibit activities as type I positive allosteric modulators (PAMs) of human alpha 7 nAChR expressed in Xenopus oocytes in two-electrode voltage clamp assay. The compound 8ai was a potent and efficacious PAM with an EC50 = 3.34 +/- 1.13 mu M and the maximum activation effect of alpha 7 current over 1474 +/- 246% in the presence of acetylcholine (100 mu M). It is highly specific to alpha 7 nAChR over other subtypes of nAChR and 5-HT3A receptors. The structure-activity relationship analysis identified a key skeleton of nicotinamide nucleus critical for biological activity. Taken together, the 8ai as a type I PAM of alpha 7 nAChR may be beneficial for improvement of cognitive deficit.

Dendrimers are of great interest due to their special structural topology and chemical versatility. Owing to their properties, dendrimers have found practical applications in catalytic processes as efficient nanoreactors. Therefore, we herein report an environmentally attractive strategy and highly efficient route for the synthesis of a wide variety of diaryl sulfides using palladium nanoparticles immobilized on a nano-silica triazine dendritic polymer (Pd-np-nSTDP) as a nanoreactor. In this manner, different diaryl or aryl heteroaryl sulfides and bis(aryl/heteroarylthio)benzene/anthracene/pyridine derivatives were preparedviaC-S cross-coupling reactions of aryl halides with diaryl/diheteroaryl disulfides under thermal conditions and microwave irradiation. The catalyst could be easily recovered and reused several times without any significant loss of its activity.

In this study, we introduced 1, 2, 4-triazole groups into panaxadiol (PD) to obtain 18 panaxadiol triazole derivatives. Five cancer cells and one normal cell were evaluated for cytotoxicity by MTT assay. The results showed that most of the derivatives could inhibit cancer cell proliferation, and the anti-proliferative activity of compound A1 was the most significant. For HepG-2 cells, the IC50 value was 4.21 +/- 0.54 mu M, which was nearly 15 times higher than the activity of PD. Further studies showed that compound A1 could induce apoptosis in HepG-2 cells, and could enhance the expression of Cl-caspase-3, Cl-caspase-9 and Cl-PARP. Moreover, Western blot analysis showed that after treating HepG-2 cells with compound A1, the expression of p53 protein was increased and the ratio of Bax/Bcl-2 was gradually increased. The cytoplasmic Bax is then translocated to the mitochondria, causing the release of Cyt c protein. Therefore, the results indicate that compound A1 induces apoptosis through the mitochondrial pathway and can be used the potential to develop new anti-proliferative agents.
