Rapid and selective visualization of mitochondrial hypochlorite by a red region water-soluble fluorescence probe

Hypochlorite (-OCl) has long been recognized as an effective microbicidal agent in immune system. Herein, we report the design, preparation and spectral characteristics of a -OCl fluorescent probe (FI-Mito). The probe exhibited remarkable fluorescence turn-on signal in the red region upon -OCl titration with the detection limit as low as 0.9 nM. FI-Mito displayed specific response for -OCl in completely aqueous solution. Meanwhile, the introduction of quaternized pyridine realized mitochondria-targeting ability. FI-Mito was further applied to monitor the generation of endogenous -OCl in the mitochondria of macrophage cells and mice. Therefore, it was established that FI-Mito may serve as a useful molecular tool for -OCl detection in vivo. (C) 2020 Elsevier B.V. All rights reserved.

Crystal structure of pyridinium tetraisothiocyanatodipyridinechromium(III) pyridine monosolvate

In the crystal structure of the title compound, (C5H6N)[Cr(NCS)(4)(C5H5 N)(2)]center dot-C5H5N, the Cr-III ions are octahedrally coordinated by four N-bonding thiocyanate anions and two pyridine ligands into discrete negatively charged complexes, with the Cr-III ion, as well as the two pyridine ligands, located on crystallographic mirror planes. The mean planes of the two pyridine ligands are rotated with respect to each other by 90 degrees. Charge balance is achieved by one protonated pyridine molecule that is hydrogen bonded to one additional pyridine solvent molecule, with both located on crystallographic mirror planes and again rotated by exactly 90 degrees. The pyridinium H atom was refined as disordered between both pyridine N atoms in a 70:30 ratio, leading to a linear N-H center dot center dot center dot N hydrogen bond. In the crystal, discrete complexes are linked by weak C-H center dot center dot center dot S hydrogen bonds into chains that are connected by additional C-H center dot center dot center dot S hydrogen bonding via the pyridinium cations and solvent molecules into layers and finally into a three-dimensional network.

Catalytic Hydrodenitrogenation of Pyridine under Hydrothermal Conditions: A Comprehensive Study

This article focuses on the kinetic modeling and catalytic performance of hydrodenitrogenation of pyridine under hydrothermal conditions. Piperidine derivatives are the major nitrogen-containing intermediates, including 1-piperidinecarboxaldehyde, 1-piperidineethanol, and alkyl piperidines. Catalysts overall improved the formation of N-free products including 1-pentanol and 2-methyl-1-pentanol. Commercial Pd/C provided the highest pyridine conversion rate at 350 degrees C, while the homemade Ni-Ru bimetallic catalyst provided a prominent denitrogenation activity at 400 degrees C, leading to the highest 1-pentanol yield as a major denitrogenated product. Conversion of pyridine over the Ni50Ru50/C catalyst led to formation of three major alkyl piperidines (1-ethyl piperidine, 1-methyl piperidine, and 1-pentyl piperidine). These alkyl piperidine intermediates could further be converted into amino and N-free compounds. A kinetic model was developed to mathematically describe the hydrothermal HDN reaction of pyridine over the Ni50Ru50/C catalyst, which clearly captured all data trends and fitted the temporal variation of all major products. Sensitivity analysis suggested that dehydrogenation from piperidine to pyridine has a strong impact on the whole reaction pathways.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Concise design and synthesis of pyridine-fused heterocycles via 6 pi- Azaelectrocyclization process of iminoalkyne derivatives

A concise and regioselective approach to the synthesis of pyridine-fused heterocycles and benzoxazepine derivatives was developed. Propargyl imines derived from aromatic aldehydes and propargyl amine underwent 6 pi-electrocyclization reactions at high temperatures in high yields to form pyridine-fused heterocycles. Application of the same methodology to aromatic imines having a hydroxyl group in the ortho position resulted in the formation of (benz)oxazepine derivatives. The formation mechanism of the products was discussed. (C) 2019 Elsevier Ltd. All rights reserved.

Electronic properties and frontier molecular orbitals of the complexes were investigated by DFT and TD-DFT calculations. DNA interaction studies were evaluated by UV-visible absorption, fluorescence and circular dichroism spectral studies which indicated noncovalent binding of complexes with CT-DNA. Hirshfeld surface analysis of all the complexes was studied to know the weak interaction present in the molecules.

CO2 Hydrogenation to CH3OH on Supported Cu Nanoparticles: Nature and Role of Ti in Bulk Oxides vs Isolated Surface Sites

The selective hydrogenation of CO2 to CH3OH is a crucial part of efforts to mitigate climate change via the methanol economy. Understanding the nature and role of active sites is essential for designing highly active and selective catalysts. Here, we examine Cu nanoparticles dispersed on TiO2 and Ti-containing SiO2 supports, where the Ti moieties of these materials are reducible to different extents, using a surface organometallic chemistry approach, together with state-of-the-art characterization methods (UV- vis, infrared (IR), electron paramagnetic resonance (EPR), and nuclear magnetic resonance (NMR) spectroscopies and in situ transmission electron microscopy (TEM)). Cu nanoparticles are small and well-dispersed on isolated, dimeric, and oligomeric Ti moieities on SiO 2 when reduced or when the material has been oxidized via exposure to air, but they are small only in the latter case for Cu dispersed on the bulk oxide TiO2. Large Cu nanoparticles, present on TiO2 when reduced, redisperse upon exposure to air, likely associated with the facile oxidation of the reduced TiO2 surface, and agglomerate again when reduced in situ within the electron microscope. CH3OH formation rates and selectivities on Cu/TiO2 are low as a result of these large Cu nanoparticles and the ability of TiO2 to catalyze the hydrogenation of CO2 to CO. After accounting for the CO formation rates of the support itself, the CH3OH selectivities are similar for all catalysts (and greater than that for Cu/SiO2, where SiO2 is considered as an innocent support), suggesting that Ti sites in all materials have a similar nature and role. These Ti sites act as Lewis acid sites, whose presence is evidenced by pyridine adsorption studies using IR and NMR spectroscopies, that stabilize the same surface intermediates at the interface of Cu nanoparticles and the support, despite differences in the reducibility of these Ti species.

Visible-Light-Induced ortho-Selective Migration on Pyridyl Ring: Trifluoromethylative Pyridylation of Unactivated Alkenes

The photocatalyzed ortho-selective migration on a pyridyl ring has been achieved for the site-selective trifluoromethylative pyridylation of unactivated alkenes. The overall process is initiated by the selective addition of a CF3 radical to the alkene to provide a nucleophilic alkyl radical intermediate, which enables an intramolecular endo addition exclusively to the ortho-position of the pyridinium salt. Both secondary and tertiary alkyl radicals are well-suited for addition to the C2-position of pyridinium salts to ultimately provide synthetically valuable C2-fluoroalkyl functionalized pyridines. Moreover, the method was successfully applied to the reaction with P-centered radicals. The utility of this transformation was further demonstrated by the late-stage functionalization of complex bioactive molecules.
