Pyridine Complexes as Tailored Precursors for Rapid Synthesis of Thiophosphate Superionic Conductors

Room temperature solution synthesis of electrolytes for all-solid-state batteries has garnered much interest in the past years as a more scalable and efficient alternative to traditional solid-state syntheses. Li3PS4, a model solid electrolyte often studied, is typically produced from Li2S and P4S10; the latter exists as a molecular solid in an adamantane-like cage structure, and it has been posited that from its robustness arises a rate-limiting reaction step. In this work, we have applied chemistry inspired from the organic thionation literature to easily transform the cage-like P4S10 into more reactive stabilized linear P2S5 molecules. This new reagent was used to drastically reduce the synthesis time of Li3PS4 in acetonitrile from days to hours. Because the long reaction time of many solvent routes to produce solid electrolytes is considered a bottleneck for commercialization, this work shows great promise for looking toward more fundamental chemistry in order to optimize solution syntheses.

Comparative Metabolic Responses Induced by Pyridine and Imidazole in Blakeslea trispora

Lycopene cyclase needs to be inhibited by the blockers like pyridine or imidazole in the lycopene accumulation of Blakeslea trispora. This work investigated how pyridine and imidazole impacted the basal metabolism of B. trispora, the results helped us understand how they could affect the lycopene production and application, and see the metabolic risks from different inhibitors. In this study, the highest yield of lycopene with pyridine was obtained at 176 mg/L without amino acids supplement, and got more lycopene at 237 mg/L adding tyrosine, lysine, proline all together as 0.01 mol/L each in fermented broth. GC-MS and Principal Component Analysis (PCA) were used to find that amino acids, fatty acids, organic acids including phosphoric acid, carbon source and imidazole derivatives played the most important roles in lycopene fermentation with imidazole, differently, fatty acids, carbon source, and pyridine derivatives were more significant in the pyridine process and it was remarkable that the residual of both blockers’ derivatives would bring the potential risks on applications of lycopene products. Predominantly, durene met 0.35 mg/g DCW with imidazole and piperidine formaldehyde attained 0.24 mg/g DCW with pyridine after the end of lycopene fermentations.

A binuclear chloride bridged Cu(II) and a mononuclear Ni(II) complex: Synthesis, crystal structure, photo catalytic and biological studies

In the present paper, one new binuclear chloride bridged Cu(II) complex [Cl2Cu-(mu-Cl)-Cu(L)Cl-2] (1) and one mononuclear Ni(II) complex [Ni(L ‘)(2)](ClO4)(2) (2) where L = N-1-(pyridine-2-ylmethylene)-N-2-(2-(pyridine-2-ylmethyleneamino)ethyl)ethane-1,2-diamine derived from pyridine-2-aldehyde and diethylenetriamine, L’ = Piperidine-2-yl-N-(pyridine-2-ylmethylene)methanamine derived from pyridine-2-aldehyde and 2-aminomethylpiperidine have been synthesized and characterized by single crystal X-ray diffraction studies. The crystal structure of the binuclear Cu(II) complex (1) shows that the two square pyramidal Cu(II) moieties are joined through a single chloride (mu-Cl) bridge and the coordination environment around the two copper atoms are same, whereas the nickel ion in complex (2) has an octahedral geometry. The antibacterial study for metal salts, ligands and complexes were performed using Staphylococcus aureus. The result shows that among the complexes, complex (2) exhibits better antibacterial properties than complex (1). Optical band gaps of 3.3 and 3.1 eV for complexes 1 and 2 respectively reveal that both the complexes have some semiconducting properties. Photo catalytic activity and H2O2 sensing activity for both the complexes were also determined. The photo catalytic test was performed against Rhodamine B (RB), Methylene Blue (MB), Malachite Green (MG) and Bromocressol Green (BG) in presence of sunlight. Results of photo catalytic and H2O2 sensing tests have revealed that both the complexes have degradation ability against each dye but complex 1 have only H2O2 sensing properties. DNA binding ability of the complexes was done by absorption titration, ethidium bromide displacement and viscosity measurement studies. Furthermore, molecular docking studies for complex 2 were also performed with B-DNA model sequence. It has been shown that complex 2 interacts with DNA through partial intercalation as well as minor-groove binding. The cell viable activity of the ligand, copper and nickel complexes were measured in vitro against the Hela cell and it shows that the metal complexes are biocompatible in nature. So the utility of this study is that the complexes under investigation can effectively be used as pharmaceutical components in several antibacterial drugs as they are biocompatible in nature and can also be used in waste dye degradation or separation process from water or to detect H2O2 widely used in food, cosmetic, pharmaceutical and paper industries.

Magnetic Assembly Route to Construct Reproducible and Recyclable SERS Substrate

The fabrication of a uniform array film through assembly of colloidal building blocks is of practical interest for the integrated individual and collective functions. Here, a magnetic assembly route was put forward to organize monodisperse noble metal microspheres into a uniform array film for surface-enhanced Raman scattering (SERS) application, which demonstrated the integrated signal sensitivity of single noble metal microspheres and reproducibility of their assembled uniform array film. For this purpose, monodisperse multifunctional Fe3O4@SiO2@TiO2@Ag (FOSTA) colloidal microspheres as building blocks were successfully synthesized through a homemade ultrasonic-assisted reaction system. When used in SERS test, these multifunctional microspheres could firstly bind the analyte (R6G) from solution and then assembled into a uniform film under an external magnetic field, which exhibited high SERS detection sensitivity with good reproducibility. In addition, due to the TiO2 interlayer in FOSTA colloidal microspheres, the building blocks could be recycled and self cleaned through photocatalytic degradation of the adsorbed analyte for recycling SERS application.

Colorimetric metal ion (II) Sensors Based on imine boronic esters functionalized with pyridine

The one-step synthesis of three imine boronic esters functionalized with pyridyl groups is described (1a-1c). The presence or absence of a methyl group affects the whole conformation, being bent L or linear as determined by X-ray crystal diffraction. C-H center dot center dot center dot O, C-H center dot center dot center dot N, C-H center dot center dot center dot F and C-H center dot center dot center dot pi hydrogen bond interactions support 2D supramolecular arrangements. Ligands were tested as metal ion (M2+) sensors in solution. The addition of metal cations (Fe2+, Co2+ and Cu2+) to 1a using methanol as solvent, showed significant color changes (purple, orange and green, respectively), while for metal cations Ni2+, Zn2+, Cd2+ cations no color changes were observed. The sensitivity of compound 1a towards Fe2+, Co2+ and Cu2+ was monitored by UV-Vis spectroscopy, where the presence of Fe2+ produces new bands at 360 and 566 nm. For Co2+ and Cu2+ a remarkable intensity increase was observed at 290 nm band and new bands appear at 340 and 462 nm, respectively. The stoichiometry of the complexes 1a-Fe2+, 1a-Co2+ and 1a-Cu2+ was determined by Job’s plots being 1:3 (metal:ligand, complex [Fe (1a)(3)](2+)), in contrast with the stoichiometry 1:1 observed for 1b-Fe2+. In fact, the computed Delta G formation associated value showed a strong stabilization for the complex [Fe (1a)(3)](2+) (-65.5 kcal/mol) in comparison with the possible complex [Fe (1b)(3)](2+) (-29.7 kcal/mol). Detection limits are in the mM range (determined by UV-Vis) and mu M range (determined by Fluorescence). An analogous bis-bidentate derivative (2a) also shows similar behavior but stoichiometric interaction changes to 2:3 (metal:ligand) and detection limits are in the mM range obtained by UV-Vis and Fluorescence techniques.

Compatibilized polypropylene nanocomposites containing expanded graphite and graphene nanoplatelets

We present a non-covalent compatibilization approach to prepare polypropylene (PP) composites containing expanded graphite (EG) and graphene nanoplatelets (GNPs) by melt compounding. This method involves PP matrix functionalization with pyridine (Py) moieties, which are capable of engaging in pi-pi interactions with the surface of the EG and GNPs. The addition of 10 wt% of PP grafted with amino-pyridine (PP-g-Py) to neat PP facilitated the break-up of EG particles, by intercalating between their layers and facilitating their separation into smaller tactoids. GNPs were prepared starting from EG through a thermomechanical exfoliation method. Addition of GNPs to PP resulted in well-dispersed platelets having aspect ratios as high as 40, whereas in the presence of the PP-g-Py compatibilizer the matrix contained sub-micron scale platelets. The electrical percolation thresholds were in the vicinity of 6 and 10 vol% in the compatibilized PP-EG and PP-GNP composites, respectively, and the maximum value of the electrical conductivity achieved was 10(-1) S/m for the compatibilized GNP composites. Addition of GNPs resulted in increases in the flexural moduli by as much as 95% compared to the unfilled PP, whereas the impact strength remained unaffected up to 10 wt% GNP content.

4-(Dimethylamino)pyridine as Multivalent Catalyst in Organic Synthesis

4-(Dimethylamino)pyridine (DMAP) is an common and well-known catalyst in organic synthesis.([1,2]) It has basic and nucleophilic character, commonly exploited in reactions.([3,4]) DMAP has moderate aqueous solubility, which allows it to be used in aqueous reactions for green chemistry.([5,6]) Despite being toxic, DMAP is a versatile and inexpensive catalyst, able to promote different types of reactions with an emphasis on heterocycle synthesis,([7-15]) cycloadditions,([7,8]) multicomponent reactions (MCRs),([10,13,14,16,17]) and acylation reactions.([1,18-21]) It is also worth noting its growing use as a catalyst in stereoselective reactions.([7,22,23]) There are several methods for DMAP synthesis.([24,25]) An efficient protocol that provides DMAP (1) (Scheme 1) in high yield involves nucleophilic aromatic substitution (SNAr) of 4-chloropyridine hydrochloride (2) and dimethylamine in 1,4-dioxane and sodium hydroxide at 70 degrees C under pressure.([24]) Other methods such as continuous flow, which is a fast and economical protocol,([26]) can lead to successful DMAP synthesis. In this SNAr protocol,([25]) a nucleophile is formed through a reaction between DMF and NH3, which is then added to 4-chloropyridine hydrochloride (1) at high temperature and pressure to synthesize DMAP in 78% yield (Scheme 1).([25])

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.

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.
