Thopate, Yogesh;Singh, Richa;Rastogi, Sumit K.;Sinha, Arun K. research published 《 Cascade Multicomponent Reaction Involving Unprecedented Gould Jacobs-Heck/Suzuki Coupling-Hydrolysis-Decarboxylation Reactions in One Pot: Rapid Synthesis of Hybrid Heterocyclic Molecules》, the research content is summarized as follows. Multicomponent one-pot five-step reactions by combining two known name reactions viz. Gould-Jacobs reaction and Heck reaction for the synthesis of stilbene/biaryl-quinolone hybrid mols. I [R = H, F; R¹ = Ph, 4-MeC₆H₄, 4-ClC₆H₄, etc.], while Gould-Jacobs reaction and Suzuki reaction for II [R² = Ph, 4-OMeC₆H₄, 4-FC₆H₄, 3-ClC₆H₄] from readily available 4-iodoanilines, (diethyl-2-(ethoxymethylene)malonate) and styrenes/aryl boronic acids was reported. The use of di-Ph ether as a reaction solvent effectively mediated not only the Gould-Jacobs reaction but surprisingly also the Heck reaction for the first time. Further, di-Ph ether also allowed easy isolation of crude product due to polar nature of the product via precipitation The developed protocol thus offered unprecedented synthesis of hybrid mols. by converging five steps (Gould-Jacobs reaction, Heck or Suzuki cross coupling, hydrolysis and decarboxylation) into one pot with simultaneous generation of C-C and C-N bonds besides cleavage of C-O and C-C bonds.

Tata, Alessandra;Massaro, Andrea;Riuzzi, Giorgia;Lanza, Ilaria;Bragolusi, Marco;Negro, Alessandro;Novelli, Enrico;Piro, Roberto;Gottardo, Flaviana;Segato, Severino research published 《 Ambient mass spectrometry for rapid authentication of milk from Alpine or lowland forage》, the research content is summarized as follows. Metabolomics approaches, such as direct anal. in real time-high resolution mass spectrometry (DART-HRMS), allow characterizing many polar and non-polar compounds useful as authentication biomarkers of dairy chains. By using both a partial least squares discriminant anal. (PLS-DA) and a linear discriminant anal. (LDA), this study aimed to assess the capability of DART-HRMS, coupled with a low-level data fusion, discriminate among milk samples from lowland (silages vs. hay) and Alpine (grazing; APS) systems and identify the most informative biomarkers associated with the main dietary forage. As confirmed also by the LDA performed against the test set, DART-HRMS anal. provided an accurate discrimination of Alpine samples; meanwhile, there was a limited capacity to correctly recognize silage- vs. hay-milks. Supervised multivariate statistics followed by metabolomics hierarchical cluster anal. allowed extrapolating the most significant metabolites. Lowland milk was characterised by a pool of energetic compounds, ketoacid derivates, amines and organic acids. Seven informative DART-HRMS mol. features, mainly monoacylglycerols, could strongly explain the metabolomic variation of Alpine grazing milk and contributed to its classification. The misclassification between the two lowland groups confirmed that the intensive dairy systems would be characterised by a small variation in milk composition

Tanaka, Shinji;Nakajima, Yumiko;Ogawa, Atsuko;Kuragano, Takashi;Kon, Yoshihiro;Tamura, Masanori;Sato, Kazuhiko;Coperet, Christophe research published 《 DNP NMR spectroscopy enabled direct characterization of polystyrene-supported catalyst species for synthesis of glycidyl esters by transesterification》, the research content is summarized as follows. Polymer-supported catalysts have been of great interest in organic syntheses, but have suffered from the difficulty in obtaining direct structural information regarding the catalyst species embedded in the polymer due to the limitations of most anal. methods. Here, author show that dynamic nuclear polarization (DNP)-enhanced solid-state NMR is ideally positioned to characterize the ubiquitous cross-linked polystyrene (PS)-supported catalysts, thus enabling mol.-level understanding and rational development. Ammonium-based catalysts, which show excellent catalytic activity and reusability for the transesterification of Me esters with glycidol, giving glycidyl esters in high yields, were successfully characterized by DNP ¹⁵N NMR spectroscopy at ¹⁵N natural abundance. DNP ¹⁵N NMR shows in particular that the decomposition of quaternary alkylammonium moieties to tertiary amines was completely suppressed during the catalytic reaction. Furthermore, the dilute ring-opened product derived from glycidol and NO₃^– was directly characterized by DNP ¹⁵N CPMAS and ¹H-¹⁵N and ¹H-¹³C HETCOR NMR using a ¹⁵N enriched (NO₃) sample, supporting the view that the transesterification mechanism involves an alkoxide anion derived from an epoxide and NO₃^–. In addition, the detailed anal. of a used catalyst indicated that the adsorption of products on the cationic center is the major deactivation step in this catalysis.

Tan, Ming;Chen, Chen;Fu, Xin;Cui, Feng-Jie;Zhang, Hai-Bo;Ye, Ping-Ping;Zhang, Wei;Shu, Xue-Quan;Shi, Jian-Cheng;Chen, Zhi-Wei research published 《 Roasting treatments affect physicochemical, aroma and nutritional quality of strong fragrant rapeseed oil》, the research content is summarized as follows. The strong fragrant rapeseed oil (SFRO) attracts the growing interest in China due to its fragrant flavor, attractive color, and phys. and oxidative stability. It is usually produced with simple processes including rapeseed roasting, mech. pressing, and degumming with hot water (80-90°C). To produce SFROs with high quality and nutritional contents, the seed roasting parameters including temperature up to 220°C and time ranging from 10 min to 30 min were investigated. Results showed that 20-min roasting at temperature 160°C resulted in the highest oil extraction yield of 33.20% with the lowest water content of 0.121%. The produced SFRO had the roasted, nutty and soft tastes with the maximum overall score, the highest total tocopherol and sterol contents of 789.73 mg/kg and 4582.80 mg/kg, resp., and high CoQ10 content of 65.57 mg/kg. Over-roasting at roasting temperature of over 180°C and time of over 30 min led to the high Lovibond red readings, off-flavors, and increased concentrations of high saturated fatty acids and Benzo[a]pyrene (BaP). Our findings would provide a reference to produce SFROs with the highest extraction yield and nutrient contents, acceptable physicochem. properties, optimal profile of the fatty acids and the key aroma compounds, and relatively-low BaP concentration

Tahara, Yu-ki;Kietrys, Anna M.;Hebenbrock, Marian;Lee, Yujeong;Wilson, David L.;Kool, Eric T. research published 《 Dual Inhibitors of 8-Oxoguanine Surveillance by OGG1 and NUDT1》, the research content is summarized as follows. Oxidative damage in DNA is one of the primary sources of mutations in the cell. The activities of repair enzymes 8-oxoguanine DNA glycosylase (OGG1) and human MutT Homolog 1 (NUDT1 or MTH1), which work together to ameliorate this damage, are closely linked to mutagenesis, genotoxicity, cancer, and inflammation. Here we have undertaken the development of small-mol. dual inhibitors of the two enzymes as tools to test the relationships between these pathways and disease. The compounds preserve key structural elements of known inhibitors of the two enzymes, and they were synthesized and assayed with recently developed luminescence assays of the enzymes. Further structural refinement of initial lead mols. yielded compound 5 (I) (SU0383) with IC50 (NUDT1) = 0.034μM, IC50 (OGG1) = 0.49μM. I displayed low toxicity in two human cell lines at 10μM. Experiments confirm the ability of I to increase sensitivity of tumor cells to oxidative stress. Dual inhibitors of these two enzymes are expected to be useful in testing multiple hypotheses regarding the roles of 8-oxo-dG in multiple disease states.

Taggart, Garrett A.;Lorzing, Gregory R.;Dworzak, Michael R.;Yap, Glenn P. A.;Bloch, Eric D. research published 《 Synthesis and characterization of low-nuclearity lantern-type porous coordination cages》, the research content is summarized as follows. Permanent porosity in lantern-type M₄L₄ paddlewheel-based cages is rare and has only been reported for naphthalene, naphthyridine, and diethynylbenzene-based linkers. This work presents the design, synthesis, and characterization of small lanterns that exhibit CO₂ accessible BET surface areas in excess of 200 m² g^-1. The crystal packing and porosity of these cages can be tuned by either ligand functionalization or the choice of M²⁺ source used in their synthesis. Given their low nuclearity, these cages with internal M-M distances of less than 5 Å represent the lower size limit for permanently microporous coordination cages.
