Molecular design and properties of bridged energetic pyridines derivatives

A series of bridged pyridine-based energetic derivatives were designed and their geometrical structures, electronic structures, heats of formation, detonation properties, thermal stabilities, thermodynamic properties and electrostatic potential were fully investigated using density functional theory. The results show that the steric hindrance effect is a decisive factor for structural stability, and the formation of intramolecular or intermolecular hydrogen bonds doesn’t provide advantages to stabilize molecular structure, which was demonstrated by insertion of 3,4,5-trinitro-1H-pyrazole, 3,4-dinitro-1H-pyrazol-5-amine, 3,5-dinitro-1H-pyrazol-4-amine and 3-nitro-1H-1,2,4-triazol-5-amine. The azide group and azo bridge play an important role in improving the heats of formation of energetic pyridine-based materials. All designed molecules were found to have values of density ranging from 1.70 g cm(-3) (E6, F6) to 2.11 g cm(-3) (D3), values of detonation velocity ranging from 7.1 km s(-1) (F1) to 9.77 km s(-1) (D8), and values of detonation pressure ranging from 21.5 GPa (F1) to 46.0 GPa (D8). When a p-pi conjugation formed between the nitrogen atom and pyridine ring, the bond between nitrogen and hydrogen atoms may be broken as the trigger bond.

Structural prediction for square-planar [M(dmf)(4)] type and octahedral cis/trans-[MX2(dmf)(4)] type complexes on the basis of group theory method

Three-dimensional structures were predicted for square-planar [M(dmf)(4)] type and octahedral cisltrans[MX2(dmf)(4)] type complexes (dmf: dimethylformamide), by a density functional theory (DFT) method, considering all of the possible isomer structures obtained by the group theory method. This method can consider the isomers in a MECE (mutually exclusive and collectively exhaustive) way, and this leads to an effective isomer search without duplicate DFT calculations. In this study, structural prediction was conducted for [Cu(dmf)(4)](2+) and [Ni(tmen)(dmf)(4)](2+), and the predicted structures were compared with the crystal structures reported earlier. For [Cu(dmf)(4)](2+), the predicted structure matched the actual structures in the crystal. For [Ni(tmen)(dmf)(4)](2+), the predicted structure matched one of the two structures in the crystal. Additional prediction was conducted also for [Ni(NH3)(2)(dmf)(4)](2+), [Ni(py)(2)(dmf)(4)](2+) (py: pyridine), and [NiCl2(dmf)(4)]. (C) 2020 Elsevier B.V. All rights reserved.

Reactions of substituted pyridylalkanol 6-CH3PyCH2CH(OH)R (R = Ph ((LH)-H-1), R = 4-CH3C6H4 ((LH)-H-2), R = 4-OCH3C6H4 ((LH)-H-3), R = 4-ClC6H4 ((LH)-H-4), R = 4-BrC6H4 ((LH)-H-5), R = 4-CF3C6H4 ((LH)-H-6)) with Ru-3(CO)(12) in refluxing tetrahydrofuran afforded the corresponding ruthenium carbonyl complexes [6-CH3PyCH2CHRO](2)Ru-3(CO)(8) (R = Ph (1a), R = 4-CH3C6H4 (1b), R = 4-OCH3C6H4 (1c), R = 4-ClC6H4 (1d), R = 4-BrC6H4 (1e), R = 4-CF3C6H4 (1f)) in good yields. These ruthenium complexes were well characterized using elemental analysis and Fourier transform infrared and NMR spectroscopies. Furthermore, their crystal structures were determined using single-crystal X-ray diffraction analysis. Complexes 1a-1f were found to be highly active toward oxidation of a wide range of primary and secondary alcohols to corresponding aldehydes and ketones within 5 minutes in the presence of N-methylmorpholine-N-oxide as oxidant.

Evaluation of Polyvinyl Chloride Functionalized with 3-(2-Thiazolylazo)-2,6-diaminopyridineas a New Chelating Resin for On-line Pre-concentration and Determination of Traces of Cadmium in Real Samples by Flame Atomic Absorption Spectrometry

In the present work, an on-line solid-phase extraction system is proposed for the preconcentration and accurate determination of trace amounts of cadmium(II) ions by flame atomic absorption spectrometry. The preconcentration of cadmium(II) ions was performed using polyvinyl chloride functionalized with 3-(2-thiazolylazo)-2,6-diaminopyridine in a minicolumn system. The adsorbed cadmium(II) ions were then eluted from the sorbent by the eluent. The important influencing parameters such as the sample solution pH, type and concentration of the eluent used for stripping cadmium(II) ions from the sorbent, flow rate of the sample and the eluent, and the amount of adsorbent were investigated in detail. Under the optimum experimental conditions, the linear dynamic range of the method was found to be in the range of 2.0-40.0 mu.g l(-1) (with the determination coefficient equal to 0.9987). The limit of detection and improvement factor were 0.7 mu.g l(-1) and 52.4, respectively. The inter assay precession (RSD%, n = 7) was in the range of 0.8-4.1% at the concentration levels of 5.00, 9.00 and 25.0 mu.g l(-1). The validated method was successfully employed for determination of cadmium(II) ions at trace levels in the spiked water and soil samples with satisfactory results.

Preparation and in vitro bioactivity evaluation of N-heterocyclic-linked dihomooxacalix[4]arene derivatives

Based on the superior prospects of calixarenes-based agents and N-heterocyclic pharmacophores in biomedical applications, 14 new dihomooxacalix[4]arene N-heterocyclic (pyridine, quinoline, and thiazole) derivatives 4a-4n were efficiently synthesized from the parent compound, namely, p-tert-butyldihomooxacalix[4]arene 1; they were further investigated by using their IR, H-1 NMR, C-13 NMR, and HRMS spectra. Among these derivatives, the crystal and molecular structures of 2-aminomethyl-pyridine-substituted dihomooxacalix[4]arene 4f (obtained from methanol) have been determined by X-ray diffraction. In the case of the inhibition assay of cell growth, we evaluated the effects on four select tumor cell lines (MCF-7, HepG2, SKOV3, and HeLa), as well as the normal cell lines of HUVEC, using paclitaxel as the positive control drug. It was found that the derivatives 4d-4f, 4i, 4k, and 4l could inhibit tumoral activity up to varying degrees. Mechanistically, the cell cycle analysis demonstrated that dihomooxacalix[4]arene N-heterocyclic derivatives could induce apoptosis of MCF cells. In addition, the results of the western blot and immunofluorescence studies revealed the upregulation of the protein expression levels of Bax and cleaved caspase-3, as well as the downregulation of Bcl-2, which are in good agreement with the corresponding inhibitory potencies. Therefore, these findings suggest that N-heterocyclic derivatives based on the dihomooxacalix[4]arene scaffold are promising candidates for use against cancer.

meso-Diketopyripentaphyrin and Diketopyrihexaphyrin as Macrocyclic Tripyrrinone Ligands for Ni-II Ions

We report expanded porphyrins with pyridine rings and two neighboring carbonyl groups, which allow Ni-II ions to coordinate to the tripyrrinone-type NNNO coordination structure with Ni-O bonds. The selectivity of tripyrrinone is superior to other pyrrolic or pyridinic cavities of expanded porphyrins. Introduction of alpha-carbonyl pyridine next to the tripyrrolic conjugated structure is a powerful strategy for regioselective metalation of flexible expanded porphyrinoids.

Impact of pyridine-2-carboxaldehyde-derived aroylhydrazones on the copper-catalyzed oxidation of the M112A PrP103-112 mutant fragment

Misfolded prion protein (PrPSc) is known for its role in fatal neurodegenerative conditions, such as Creutzfeldt-Jakob disease. PrP fragments and their mutants represent important tools in the investigation of the neurotoxic mechanisms and in the evaluation of new compounds that can interfere with the processes involved in neuronal death. Metal-catalyzed oxidation of PrP has been implicated as a trigger for the conformational changes in protein structure, which, in turn, lead to misfolding. Targeting redox-active biometals copper and iron is relevant in the context of protection against the oxidation of biomolecules and the generation of oxidative stress, observed in several conditions and considered an event that might promote sporadic prion diseases as well as other neurodegenerative disorders. In this context, ortho-pyridine aroylhydrazones are of interest, as they can act as moderate tridentate ligands towards divalent metal ions such as copper(II). In the present work, we explore the potentiality of this chemical class as peptide protecting agents against the deleterious metal-catalyzed oxidation in the M112A mutant fragment of human PrP, which mimics relevant structural features that may play an important role in the neurotoxicity observed in prion pathologies. The compounds inhere studied, especially HPCFur, showed an improved stability in aqueous solution compared to our patented lead hydrazone INHHQ, displaying a very interesting protective effect toward the oxidation of methionine and histidine, processes that are related to both physiological and pathological aging.

High catalytic hydrolysis of microcystins on pyrite surface

Eutrophication of water bodies is a phenomenon during which toxic microcystins from cyanobacteria are released into water. Natural minerals in soils and sediments are able to catalyze the degradation of microcystins. Here we studied the hydrolytic removal of microcystins on the surface of pyrite (FeS2). The surface structure of pyrite was analyzed by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy and Fourier transformed infrared. The surface acidity of pyrite was measured by in situ diffuse reflectance infrared Fourier transform spectroscopy during pyridine adsorption/desorption. The concentration of d-alanine, d-glutamic acid, l-arginine and l-leucine were determined in pyrite/microcystin aqueous solution by high-performance liquid chromatography. Hydrolysis at the pyrite-microcystin interface was monitored by attenuated total reflection Fourier transformed infrared spectroscopy. Results show that sulfion and iron are layered, wherein the sulfion is above the surface, which provides active sites for the hydrolysis of microcystins. The hydrolysis rate of microcystins was up to 100% at 60 degrees C after 24 h in the presence of pyrite, based on the yield of l-arginine. Surface Lewis (equivalent to Fe) and Bronsted acid (equivalent to SH) sites of pyrite possibly bond to the carbonyl oxygen of peptide bonds, leading to highly efficient hydrolysis of microcystins.
