Formenti, Dario; Topf, Christoph; Junge, Kathrin; Ragaini, Fabio; Beller, Matthias published the artcile< Fe2O3/NGr@C- and Co-Co3O4/NGr@C-catalysed hydrogenation of nitroarenes under mild conditions>, Application of C7H8ClN, the main research area is aniline preparation green chem chemoselective; nitroarene hydrogenation reaction doped graphene iron cobalt nanocatalyst.

An improved hydrogenation of nitroarenes such as nitrobenzene, 2-nitrobiphenyl, 2,4,6-tri-t-butylnitrobenzene, etc. using nano-structured iron- and cobalt-based catalysts has been presented. Modifications of the heterogeneous catalysts by N-doped graphene-flakes are crucial for the success of selective reductions The use of polar solvents and basic additives has a significant pos. influence on the rate of reduction of nitroarenes. This allows performing non-noble metal-catalyzed hydrogenations under very mild reaction conditions (e.g. 70 °C and 20 bar). On the basis of the obtained catalytic results a heterolytic mechanism for the hydrogenation process is postulated, too.

The transformation proceeds under mild reaction conditions to afford the corresponding phenylacetic acids in good to excellent yields. This user-friendly and operationally simple protocol represents an alternative to traditional strategies, which usually proceeds through the C(sp3)-halide activation pathway.

Xiong, Jin; Liu, Yunyun published the artcile< Transition-Metal-free C5, C7-Dihalogenation and the Switchable C5 Halogenation of 8-Hydroxyquinolines>, Recommanded Product: 1-Chloropyrrolidine-2,5-dione, the main research area is dihalogenated hydroxyquinoline preparation; hydroxyquinoline acyl chloride halosuccinimide dihalogenation; halogenated hydroxyquinoline preparation; quinolinyl benzoate halosuccinimide halogenation.

The first example of the C5, C7-dihalogenation of 8-hydroxyquinolines based on an in situ O-acyl 8-hydroxyquinoline formation was realized under catalyst-free condition in toluene to synthesize 5,7-dihalogenated-8-hydroxyquinolines I [Ar = Ph, 4-FC6H4, 3-ClC6H4, etc.; R = H, 2-Me; X = Cl, Br, I]. Modifying the reaction conditions by directly utilizing O-acylated 8-hydroxyquinolines in the presence of AlCl3 enabled the electrophilic halogenation in the C5 position, led to the tunable synthesis of C5 halogenated products. The O-acyl group could be easily removed from the product to provide halogenated quinolines containing free hydroxyl group by simple hydrolysis.

Misawa, Rena; Matsuhashi, Chihiro; Yamaji, Minoru; Mutai, Toshiki; Yoshikawa, Isao; Houjou, Hirohiko; Noguchi, Keiichi; Maki, Shojiro; Hirano, Takashi published the artcile< Halogen-substituent effect on the spectroscopic properties of 2-phenyl-6-dimethylaminobenzothiazoles>, Name: 1-Chloropyrrolidine-2,5-dione, the main research area is halogen substituent phenyl dimethyl aminobenzothiazole spectroscopic property.

The 6-dimethylamino-2-phenylbenzothiazole (1-H) is a push-pull benzothiazole fluorophore mimicking the firefly oxyluciferin structure. We newly prepared 7-chloro and 7-bromo derivatives of 1-H and its 4-acetyl derivative (2-H), and their spectroscopic and photophys. properties were investigated. The halogenated derivatives showed the blue-shifted electronic absorption maxima and fluorescence emission maxima compared to 1-H and 2-H, resulted from the deformations of the NMe2 groups and the electron withdrawing properties of the halogen groups. In addition, the halogen substitutions accelerate intersystem crossing by heavy atom effect, resulting in a decrease in fluorescence quantum yields. Interestingly, however, the halogenated derivatives of 2-H still showed moderate fluorescence quantum yields. The halogenation effect is one of the guides to design push-pull benzothiazole fluorophores for tuning fluorescence properties.

Sirenko, Oksana; Cromwell, Evan F.; Crittenden, Carole; Wignall, Jessica A.; Wright, Fred A.; Rusyn, Ivan published the artcile< Assessment of beating parameters in human induced pluripotent stem cells enables quantitative in vitro screening for cardiotoxicity>, Application In Synthesis of 6055-19-2, the main research area is cardiotoxicity cardiomyocyte beating pluripotency stem cell; AUC; BMC; Calcium flux; Cardiotoxicity; DMSO; EC(50); Phenotypic screening; Predictive toxicology; area under the curve; benchmark concentration; dimethyl sulfoxide; effective concentration at 50% of the maximum response; hERG; iPSC; induced pluripotent stem cell.

Human induced pluripotent stem cell (iPSC)-derived cardiomyocytes show promise for screening during early drug development. Here, we tested a hypothesis that in vitro assessment of multiple cardiomyocyte physiol. parameters enables predictive and mechanistically-interpretable evaluation of cardiotoxicity in a high-throughput format. Human iPSC-derived cardiomyocytes were exposed for 30 min or 24 h to 131 drugs, pos. (107) and neg. (24) for in vivo cardiotoxicity, in up to 6 concentrations (3 nM to 30 uM) in 384-well plates. Fast kinetic imaging was used to monitor changes in cardiomyocyte function using intracellular Ca2+ flux readouts synchronous with beating, and cell viability. A number of physiol. parameters of cardiomyocyte beating, such as beat rate, peak shape (amplitude, width, raise, decay, etc.) and regularity were collected using automated data anal. Concentration-response profiles were evaluated using logistic modeling to derive a benchmark concentration (BMC) point-of-departure value, based on one standard deviation departure from the estimated baseline in vehicle (0.3% DMSO)-treated cells. BMC values were used for cardiotoxicity classification and ranking of compounds Beat rate and several peak shape parameters were found to be good predictors, while cell viability had poor classification accuracy. In addition, we applied the Toxicol. Prioritization Index (ToxPi) approach to integrate and display data across many collected parameters, to derive “”cardiosafety”” ranking of tested compounds Multi-parameter screening of beating profiles allows for cardiotoxicity risk assessment and identification of specific patterns defining mechanism-specific effects. These data and anal. methods may be used widely for compound screening and early safety evaluation in drug development.

Jiang, Xiaoqing; Wu, Hongping; Yu, Hongwei; Hu, Zhanggui; Wang, Jiyang; Wu, Yicheng published the artcile< Metal halide In(Ba3Cl3F6) - a novel infrared-transparent molecular sieve constructed by halides>, Name: Indium(III) chloride tetrahydrate, the main research area is metal halide manufacture barium indium chloride fluoride mol sieve.

Mol. sieves are of increasing importance in catalysis, the oil industry, and biomedicine. Traditional mol. sieves are generally oxides that inevitably show some absorption in the mid- and far-IR range due to the vibrations of metal-oxygen bonds, which are unfavorable for the in situ observation of the reactions in mol. sieves through IR techniques. In this study, a new metal halide In[Ba3Cl3F6] has been synthesized. It exhibits a quite transparent window from 0.366 to 22 μm and good adsorption and desorption processes.

Catalysts based on (R, R)-1,2-diphenylethylenediamine are, as chiral organic catalysts, applied to the asym. Michael addition to α, β-unsaturated nitroalkenes under neutral conditions. The role of an aqueous medium for organic catalytic activity can be reversed concerning hydrophilic-hydrophobic function depending on the reaction conditions. In this study, to provide an environmentally friendly system, the thiourea-based catalyst substituted with 3,5-(CF3)2-Ph was used in water solvents. The hydrophobic effect of the substituent provided fast reaction, high chem. yield, and mirror-image selectivity. This reaction allowed the preparation of GABAB agonists in an optically pure manner. Addnl., GABA (γ-aminobutyric acid) analogs such as baclofen and phenibut were synthesized as R-type S-type with high optical purity.
