Quinolines and isoquinolines were treated with Na2S2O8 in a mixture of methanol and water at 70 degrees C to form hydroxymethylated quinolines and isoquinolines in good to moderate yields, under transition-metal-free conditions. The formed hydroxymethyl group was smoothly converted into aldehyde, ester, amide, bromomethyl, (N,N-diethylamino)methyl, cyano, and tetrazole groups, in good yields.

Waxy crude oil containing large amounts of paraffins often results in various difficulties in extraction and transportation, especially at low temperature. Comb-type copolymers with phenyl pendants were found to be able to improve the flow ability of waxy oils effectively. To investigate the influence of spacer length between phenyl pendant and polymer backbone in comb copolymers on the flow ability of waxy oil, poly(alpha-octadecene-co-maleic acid phenyl alkyl amide)s with various spacer lengths were synthesized by modification of poly(alpha-octadecene-co-maleic anhydride) with aniline, phenethylamine, phentermine, and phenyl-undecanoicamide. Their effects on the morphology and crystallization of model and crude oils were observed by polarized light microscopy and DSC. The flow ability of both oils in the presence of copolymers was studied by means of rheology, including measuring yield stress, viscosity, and thixotropic properties. It is found that the spacer length remarkably affects the rheology and wax crystallization behaviors for both oils. The copolymer with a longer spacer can provide better flexibility of phenyl pendants to disperse asphaltenes more effectively, and the long spacer can cocrystallize with long-chain paraffins.

Sinapic acid (SNP) is a nutraceutical compound of hydroxybenzoic acid derivative which possesses antioxidant, anti-microbial, anti-inflammatory, anti-cancer, and anti-anxiety activity properties. In the present work, two cocrystals of SNP with two active drug ingredients such as Ethenzamide (ETZ) and 2-chloro-4-nitrobenzoic acid (CNB) are reported. Both the cocrystals were synthesized via simple solvent evaporation method and the crystal structures were characterized by Single Crystal X-ray Diffraction (SC-XRD) techniques. The cocrystals were formed via robust acid-amide heterosynthon and acid acid homosynthon between SNP and drug molecules. Both the cocrystals were crystallized in monoclinic crystal system with P 2(1)/c space group. The synthesized cocrystals were further characterized by DSC, PXRD, FT-IR, and H-1 NMR techniques. The solubility study in purified distilled water and in 0.1 N HCI solution demonstrate that there was no increment in the solubility of drug molecules in the cocrystals in both purified water and in 0.1 N HCl solution. The synthesized cocrystal exhibited six months stability at ambient conditions (similar to 25 degrees C, 60-65% RH). (C) 2018 Elsevier B.V. All rights reserved.

M-2 muscarinic acetylcholine receptor (M2R) is a prototypical G protein-coupled receptor (GPCR) that responds to acetylcholine and mediates various cellular responses in the nervous system. Here, we used attenuated total reflection-Fourier transform infrared spectroscopy analyses on M2R reconstituted in a lipid membrane to understand the molecular mechanism behind the ligand binding-induced conformational changes. Upon agonist binding, M2R shows large spectral change of the amide-I band corresponding to backbone C=O stretch, which likely connects with the receptor activation in the lipid environment. These results pave the way to probe effects of different ligand binding on GPCRs using vibrational spectroscopy.

Strong electron-withdrawing materials of bis(trifluoromethanesulfonyl) amide (TFSA, [CF3SO2](2)NH) and bis(trifluoromethane) sulfonimide lithium salt (LiTFSI, [CF3SO2](2)NLi) are incorporated into the active layers of a porphyrin small molecule TDPPEZnP and PC61BM for bulk heterojunction solar cells. While the solar cells based on the undoped devices show a power conversion efficiency (PCE) of 6.11% with a V-oc of 0.70 V, a J(sc) of 13.92 mA cm(-2) and a FF of 62.71%, doping the active layers with very low loadings of LITFSI and TFSA leads to improved PCEs of 6.85% and 7.01% with J(sc) values of 14.97 and 15.39 mA cm(-2) and FF values of 64.73% and 63.92%, accounting for 14% and 16% PCE enhancement, respectively. The improved performance is ascribed to the enhanced charge carrier transport, which is supported by charge mobility, impedance spectroscopy and transient spectroscopy analyses.

Ready availability, low cost and low toxicity of cobalt salts have redirected the attention of researchers away from noble metals, such as Pd, Rh, and Ir, towards Co in the field of C-H functionalization. In this context, the examples of Co-catalysed functionalization have exponentially grown over the last few decades. This present review focuses on the most recent developments on Co-catalysed C(sp(2))-H and C(sp(3))-H functionalizations.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. Safety of L-SelenoMethionine, 3211-76-5, Name is L-SelenoMethionine, SMILES is O=C(O)[C@@H](N)CC[Se]C, in an article , author is Hassan, Mubashir, once mentioned of 3211-76-5.

O-Acetylation of sialic acid (Sia) modulates its recognition by sialic acid-binding proteins and plays an important role in biological and pathological processes. 9-O-Acetylation is the most common modification of sialic acid in human. However, study of O-acetylated sialoglycans is hampered due to the instability of O-acetyl group towards pH changes and sensitivity to esterases. Our previous studies demonstrated a chemical biology method to this problem by replacing the oxygen atom in the C9 ester group of sialic acid by a nitrogen to form an amide. Here, we synthesized a library of sixteen new 9acetamido- 9-deoxy-N-acetylneuraminic acid (Neu5Ac9NAc)-containing alpha 2-3- and alpha 2-6-linked sialosides with various underlying glycans using efficient one-pot three-enzyme (OP3E) sialylation systems. Neu5Ac9NAc-containing compounds with a para-nitrophenol aglycon have been used together with their 9-O-acetyl analogs in microtiter plate-based high-throughput substrate specificity studies of nine different sialidases including those from humans and bacteria. In general, similar to 9-O-acetylation, 9-Nacetyl modification of sialic acid in the substrates lowers sialic acid-cleavage activity of most sialidases. In most cases, Neu5Ac9NAc is a good analog of 9-O-acetyl sialic acid. However, exceptions do exist. For example, 9-N-and 9-O-acetyl modifications have different effects on the sialosides cleave efficiencies of a commercially available C. perfringens sialidase as well as recombinant Streptococcus pneumoniae sialidase SpNanC and Bifidobacterium infantis sialidase BiNanH2. The mechanism for the difference awaits further investigation. (C) 2017 Elsevier Ltd. All rights reserved.

A segmented polyurethane elastomer (PU) was synthesized in poly(lactic acid) (PLA) melt by reactive processing. The isocyanate component was anticipated to react with the end-groups of PLA resulting in the formation of block-copolymers. The stoichiometry of the functional groups was optimized in the preliminary experiments. Two different processing methods were compared in the further experiments: conventional mixing of PU with PLA (PLA/PU), and reactive blending (PLA-b-PU). The comparison of the structure and properties of compatibilized reactive blends and conventional physical blends clearly shows the benefits of reactive processing. Coupling resulted in a finer dispersion of the particles in the matrix leading to better mechanical properties in the reactive blend. The successful synthesis of PEA-b-PU block copolymers was confirmed by NMR spectroscopy. The isocyanate component was found to react only with the hydroxyl end-groups of PLA, while the formation of amide and acylurea groups was not detected on the carboxyl end.

The emulsion of Keratin nano ZnO was prepared by extracting the keratin from wool. Cellulose viscose fabric was treated by plasma and immersed in solution and by special chemical method the fabric was finished with keratin/ZnO. The obtained cellulose composite morphology was studied by FESEM. The peaks shown by FTIR proved the presence of functional groups (amide, polypeptide, O-H and C-H). The result has proven the presence and good distribution of keratin and nano zinc oxide. The treated samples showed very low transmission of UV irradiation indicating good UV blocking. Physical properties of treated samples show that keratin gives the water absorption property to viscose. Abrasion resistance of samples indicates that treated samples have better resistance due to its excellent mechanical properties of keratin/ZnO. The strength of samples shows that keratin has good effect on increasing the strength property of viscose.
