Organic pollutants, especially persistent organic pollutants were examined in the water and surface sediments of Taihu Lake, China. In this study, 12 water and 12 sediment samples were collected. C-18 solid-phase extraction technique was applied to extract organic pollutants from water samples. Soxhlet extraction procedure was used to extract organic pollutants from sediment samples. The anal. was performed by GC-MS controlled by a Hewlett Packard chemstation. Two hundred and seventy-three organic chems. in water were examined, 200 more than that detected in 1985; 188 chems. in sediments were detected as well. Among them 21 chems. belong to priority pollutants as well as 17 to be the endocrine disruptors. The concentrations of the pollutants were >2 times higher than that in 1985. The possible source and relation to anthropogenic activity are discussed.

Heck, Richard F. published the artcile< Aromatic haloethylation with palladium and copper halides>, COA of Formula: C6H7ClS, the main research area is aromatic haloethylation palladium halide; palladium halide aromatic haloethylation; haloethylation aromatic copper halide; copper halide aromatic haloethylation.

Aryl derivatives of Group VIII metal compounds, prepared from Group VIII metal salts and mercury, tin, or lead aryls, react with olefins in the presence of cupric halides to form 2-arylethyl halides. Chlorides are formed in higher yields than bromides. The most generally useful and readily obtainable reactants were arylmercuric halides, with lithium palladium chloride as the Group VIII metal compound Since only catalytic amounts of the palladium salt are required, this reaction provides a convenient method for introducing 2-haloethyl group into aromatic systems.

The aim of this study is to obtain new unsaturated piperazine compounds by the reaction of piperazine derivatives with acyl chlorides. Methacryloyl piperazine was synthesized from the reaction of methacrylic anhydride with piperazine. Few acyl chlorides were prepared by the reaction of thionyl chloride with carboxylic acids which were obtained as a result of the reaction of malonic acid and suitable aldehydes. The remaining acyl chlorides were synthesized by the reaction of thionyl chloride with carboxylic acids which were obtained from hydrolyzation of esters. Sym. diacyl piperazine compounds were obtained from the reaction of Methacryloyl piperazine with corresponding acyl chlorides. In addition, from the reaction of Methacryloyl piperazine and corresponding acyl chlorides, nonsym. diacyl piperazine compounds were synthesized in medium to good yields (63%-84%). Also, alkyl-acyl piperazine compounds were obtained from the reaction of allyl piperazine and cinnamyl piperazine with corresponding acyl chlorides.

Stoyanova-Slavova, Iva B.; Slavov, Svetoslav H.; Pearce, Bruce; Buzatu, Dan A.; Beger, Richard D.; Wilkes, Jon G. published the artcile< Partial least square and k-nearest neighbor algorithms for improved 3D quantitative spectral data-activity relationship consensus modeling of acute toxicity>, Electric Literature of 3964-57-6, the main research area is acute toxicity modeling QSDAR; 3D quantitative spectral data-activity relationship (QSDAR); Aquatic toxicology; Computational toxicology; Consensus modeling; Multivariate statistic.

A diverse set of 154 chems. that included US Food and Drug Administration-regulated compounds tested for their aquatic toxicity in Daphnia magna were modeled by a 3-dimensional quant. spectral data-activity relationship (3D-QSDAR). Two distinct algorithms, partial least squares (PLS) and Tanimoto similarity-based k-nearest neighbors (KNN), were used to process bin occupancy descriptor matrixes obtained after tessellation of the 3D-QSDAR space into regularly sized bins. The performance of models utilizing bins ranging in size from 2 ppm × 2 ppm × 0.5 Å to 20 ppm × 20 ppm × 2.5 Å was explored. Rigorous quality-control criteria were imposed: 100 randomized 20% hold-out test sets were generated and the average R2test of the resp. models was used as a measure of their performance, and a Y-scrambling procedure was used to identify chance correlations. A consensus between the best-performing composite PLS model using 0.5 Å × 14 ppm × 14 ppm bins and 10 latent variables (average R2test = 0.770) and the best composite KNN model using 0.5 Å × 8 ppm × 8 ppm and 2 neighbors (average R2test = 0.801) offered an improvement of about 7.5% (R2test consensus = 0.845). Projection of the most frequently occurring bins on the standard coordinate space indicated that the presence of a primary or secondary amino group-substituted aromatic systems-would result in an increased toxic effect in Daphnia. The presence of a second aromatic ring with highly electroneg. substituents 5 Å to 7 Å apart from the first ring would lead to a further increase in toxicity. Environ Toxicol Chem 2014;33:1271-1282.

Nguyen, Son T.; Kwasny, Steven M.; Ding, Xiaoyuan; Cardinale, Steven C.; McCarthy, Courtney T.; Kim, Hong-Suk; Nikaido, Hiroshi; Peet, Norton P.; Williams, John D.; Bowlin, Terry L.; Opperman, Timothy J. published the artcile< Structure-activity relationships of a novel pyranopyridine series of Gram-negative bacterial efflux pump inhibitors>, Formula: C8H8BrCl, the main research area is pyranopyridine antibacterial efflux pump inhibitor pharmacokinetics; Adjunctive therapy; Antibacterial; Efflux pump inhibitor; Enterobacteriaceae; Pyranopyridine.

Recently the authors described a novel pyranopyridine inhibitor (MBX2319) of RND-type efflux pumps of the Enterobacteriaceae. MBX2319 (3,3-dimethyl-5-cyano-8-morpholino-6-(phenethylthio)-3,4-dihydro-1H-pyrano[3,4-c]pyridine) is structurally distinct from other known Gram-neg. efflux pump inhibitors (EPIs), such as 1-(1-naphthylmethyl)-piperazine (NMP), phenylalanylarginine-β-naphthylamide (PAβN), D13-9001, and the pyridopyrimidine derivatives Here, the authors report the synthesis and biol. evaluation of 60 new analogs of MBX2319 that were designed to probe the structure activity relationships (SARs) of the pyranopyridine scaffold. The results of these studies produced a mol. activity map of the scaffold, which identifies regions that are critical to efflux inhibitory activities and those that can be modified to improve potency, metabolic stability and solubility Several compounds are significantly more effective than MBX2319 at potentiating the antibacterial activity of levofloxacin and piperacillin against Escherichia coli.

Recently, nontoxic fabrication for Cu(ln, Ga)Se2 thin films gained increasing popularity. In this work, chem. bath deposition and Sol-gel methods were utilized in the fabrication of an environmentally buffer-window (ZnS-ZnO/ZnO:AI) layer system for Cu(ln, Ga)Se2 thin film devices. The influences of conditions like annealing temperature, coating times, and Al-doping amount were investigated. The surface morphol. and optical properties illustrated a compact and uniform ZnS film with a band-gap of 3.78, which can be a good alternative to CdS film. Resistivity of 0.35 ω.cm for the ZnO/ZnO:AI film was achieved by the ideal condition of 9 coating times and 5 Al-doping amounts A cross-sectional view of the complete Cu(ln, Ga)Se2 thin film was obtained, and the structure status was analyzed.
