A robust iron catalyst for the selective hydrogenation of substituted (iso)quinolones

By applying N-doped carbon modified iron-based catalysts, the controlled hydrogenation of N-heteroarenes, especially (iso) quinolones, is achieved. Crucial for activity is the catalyst preparation by pyrolysis of a carbon-impregnated composite, obtained from iron(II) acetate and N-aryliminopyridines. As demonstrated by TEM, XRD, XPS and Raman spectroscopy, the synthesized material is composed of Fe(0), Fe3C and FeNx in a N-doped carbon matrix. The decent catalytic activity of this robust and easily recyclable Fe-material allowed for the selective hydrogenation of various (iso) quinoline derivatives, even in the presence of reducible functional groups, such as nitriles, halogens, esters and amides. For a proofof- concept, this nanostructured catalyst was implemented in the multistep synthesis of natural products and pharmaceutical lead compounds as well as modification of photoluminescent materials. As such this methodology constitutes the first heterogeneous iron-catalyzed hydrogenation of substituted (iso) quinolones with synthetic importance.

Fish gelatin films incorporated with different oils: effect of thickness on physical and mechanical properties

Properties of fish gelatin films incorporated with different oils at different thickness investigated. Gelatin films incorporated with all oils resulted in higher elongation at break (EAB) compared to control film, regardless of the oils type (P <= 0.05). Increasing the thickness of gelatin films with oils decreased the solubility value (P <= 0.05) significantly. However, water vapor permeability (WVP) of gelatin films containing oils increased as the thickness of films increased. FTIR spectra showed that incorporation of different oils into gelatin films gave effect on the molecular organization and intermolecular interaction in films matrix particularly at the wavenumber of Amide-I band and 1739-1744 cm(-1). SEM analysis revealed the addition of oils into gelatin films enhanced the roughness of the film surface and cross-section. An appropriate combination of oils at moderate thickness could improve the mechanical and barrier properties of fish gelatin films thus fulfill the application either as coatings or films.

Pd(0)-Mediated C-11-Carbonylation of Aryl(mesityl)iodonium Salts as a Route to [C-11]Arylcarboxylic Acids and Derivatives

Pd(0)-mediated C-11-carbonylation of aryl-(mesityl)iodonium salts followed by suitable quench provides a rapid room-temperature two-pot procedure for labeling arylcarboxylic acids and amide derivatives with the short-lived positron emitter carbon-11 (t(1/2) = 20.4 min) in generally good to high yields (up to 71%). High product ring selectivity (>= 13) was achieved when using mesityl as a spectator group in the diaryliodonium salt precursors. This process has potential for preparing new radiotracers for molecular imaging with positron emission tomography.

Transferrin conjugates of antitubercular drug isoniazid: Synthesis and in vitro efficacy

Tuberculosis (TB) caused by Mycobacterium tuberculosis (Mtb) has become the world’s leading killer disease due to a single infectious agent which survives in the host macrophage for the indefinite period. Hence, it is necessary to enhance the efficacy of the clinically existing antitubercular agents or to discover new anti antitubercular agents. Here, we report the synthesis, characterization and antimycobacterial evaluation of protein-drug conjugates. A carrier protein, Transferrin (Tf) was covalently conjugated to isoniazid (INH) utilizing hydrazone and amide linkers. The purity of the reactions was confirmed by SDS-PAGE while conjugation was confirmed by UV-visible spectrophotometry, MALDI-TOF analysis, and FFIR spectrophotometry. The in vitro antitubercular assay result showed that the inhibitory activity of the parent drug was conserved in both the conjugates. The conjugates were effective against intracellular Mtb H37Rv and were devoid of cytotoxic effect at therapeutic concentration. (C) 2019 Elsevier Masson SAS. All rights reserved.

Modulating functional and antioxidant properties of proteins from defatted garden cress (Lepidium sativum) seed meal by Alcalase hydrolysis

The effect of Alcalase hydrolysis on structure and peptide profiles of garden cress (GC) (Lepidium sativum) protein concentrate was investigated. The protein hydrolysates were characterized by gel electrophoresis, emulsifying and foaming properties, and in vitro antioxidant activity. The water holding capacity, foaming, and emulsification properties were markedly improved at 10.69% degree of hydrolysis (DH). FTIR spectroscopy revealed that %DH had a significant impact on the secondary structure of protein concentrate with a higher shift of amide I and amide II bands. A significant drop in the enthalpy (Delta H) values in the DSC endothermic peaks confirmed the hydrolysis of the protein concentrate. Antioxidant activities of GC protein concentrate were greatly improved with the DH. The obtained data suggest that moderate hydrolysis can improve the functional and antioxidant properties of protein concentrate, and therefore, the obtained protein hydrolysates could be exploited as protein supplements in the dietetic foods, infant formulae, and geriatric products.

Inkjet printing of particle-free silver conductive ink with low sintering temperature on flexible substrates

A facile synthesis method was developed to prepare the particle-free silver organic conducive ink, which contains silver-amide complex dispersed in glycol. Electrical and morphological characterizations were carried out to assess the performance of the ink. The patterns printed by a commercial inkjet printer (Epson R230) were treated at different temperatures and time to optimize the electrical and adhesion properties. The film sintered at 140 degrees C for 40 min showed a low electrical resistivity (about 5 mu Omega.cm) owing to the transformation of point contact to surface contact. These good performances indicated a penitential application in flexible electronics.

Synthesis and Properties of Bio-Based Nonisocyanate Thermoplastic Polyoxamide-Ureas

A green route is presented to synthesize bio-based nonisocyanate thermoplastic polyoxamide-ureas (POXAUs) containing flexible poly(propylene oxide) segments. A hexanedioxamide-diester (HDODE) was synthesized from the reaction of 1,6-hexanediamine with excessive diethyl oxalate. Four H2N- terminated polyoxamide prepolymers (PrePOXAs) were synthesized through melt polycondensation of HDODE with O,O’-bis(2-aminopropyl) poly(propylene glycol). Chain extension of PrePOXAs was conducted with bis(hydroxyethyl) hexanediurethane as a chain extender, and four chain-extended POXAs or POXAUs were prepared. The POXAUs were characterized by size exclusion chromatography, Fourier transform infrared, H-1 NMR, wide-angle X-ray scattering, differential scanning calorimetry, thermogravimetric analysis, and tensile testing. POXAUs show M-n up to 29 900 g mol(-1), melting temperature from 148 to 156 degrees C, initial decomposition over 242 degrees C, tensile strength up to 60 MPa, and elongation at break from 8 to 16%. Crystallized bio-based thermoplastic poly(oxamide urea)s with excellent thermal and mechanical properties were successfully synthesized through a nonisocyanate route.

Synthesis of magnetic Fe3O4@SiO2@Cu-Ni-Fe-Cr LDH: an efficient and reusable mesoporous catalyst for reduction and one-pot reductive-acetylation of nitroarenes

Magnetically recoverable Fe3O4@SiO2@Cu-Ni-Fe-Cr LDH was prepared under co-precipitation conditions. Characterization of the mesoporous catalyst was confirmed using Fourier-transformed infrared spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, vibration sample magnetometer, Brunauer-Emmett-Teller, thermogravimetric, differential thermogravimetric analyses and transmission electron microscopy. Reduction of nitroarenes to the corresponding arylamines and one-pot reductive-acetylation of nitroarenes to acetanilides were carried out successfully by nanoparticles of the immobilized Cu-Ni-Fe-Cr layered double hydroxide on silica-coated Fe3O4 in water as a green solvent. All reactions were carried out within 6-22min affording arylamines and N-arylacetamides in high-to-excellent yields. Reusability of the core-shell nanocatalyst was examined six times without significant loss of its catalytic activity. [GRAPHICS]
