Evans, J. D. H. L.; Cavell, B. D.; Hignett, R. R. published the artcile< Fomesafen - metabolism as a basis for its selectivity in soya>, Computed Properties of 35852-58-5, the main research area is fomesafen metabolism herbicide soybean.

Soya, maize and spiny cocklebur (Xanthium spinosum) plants were treated with 14C-side-chain labeled fomesafen (Ia) by injection and or by root uptake from nutrient solution It was established that the facile metabolism of the compound in soya, but not the other species, was the basis for its herbicidal selectivity. Excised soya leaves were treated with aqueous solutions containing Ia, 14C-nitrophenyl-labeled fomesafen (Ib) and 14C-halophenyl-labeled fomesafen (Ic). The same major radioactive metabolite, M1 was formed following treatments with Ia and Ib but treatment with Ic yielded 2 different metabolites, M2 and M3. Therefore cleavage at the di-Ph ether linkage was proven. Metabolites M2 and M3 hydrolyzed with acid to 2-chloro-4-trifluoromethylphenol. Metabolite M1 was shown by cochromatog. to be S-[3-(N-methanesulfonylcarbamoyl)-4-nitrophenyl]cysteine.

Li, Wenhui; Gao, Lihong; Shi, Yali; Wang, Yuan; Liu, Jiemin; Cai, Yaqi published the artcile< Spatial distribution, temporal variation and risks of parabens and their chlorinated derivatives in urban surface water in Beijing, China>, Reference of 3964-57-6, the main research area is spatial distribution temporal variation risk paraben chlorinated derivative; risk paraben chlorinated derivative river lake water Beijing China; Parabens; Risk assessment; Spatial distribution; Temporal variation; Urban surface water.

The occurrence and distribution of 13 target compounds, including 8 parabens, 4 chlorinated parabens and p-hydroxybenzoic acid (PHBA), were detected in surface water samples at 35 sampling sites in the Beijing River system, China. The surface water samples were collected from the main rivers and lakes in the urban area monthly from July 2013 to June 2014 (except the frozen period). Laboratory analyses revealed that parabens were ubiquitous in the surface water of Beijing. PHBA was the predominant compound in the surface water samples, with the average concentration of 239 ng/L, followed by the total amount of chlorinated parabens (average 50.1 ng/L) and parabens (average 44.3 ng/L). It is noteworthy that octylparaben with longer chain was 1st detected in the surface water. Significant difference was observed for paraben concentrations from different sampling sites, and the highest level of parabens was found in the Xiaotaihou River, which was mainly due to the untreated sewage discharge. Seasonal variation of target compounds in the urban surface water was also studied, and parabens exhibited a different temporal variation from chlorinated derivatives A combination of factors including high residual Cl level and water temperature as well as intense UV radiation might enhance the persistence of chlorinated parabens in chlorinated water during the wet season. Risk assessment showed that parabens and their chlorinated derivatives are not likely to produce biol. effects on aquatic ecosystems at current levels in the surface water of Beijing.

Yang, Ke; Liu, Qiang; Wen, Shuai; Zhuang, Tao published the artcile< Synthesis of branched polyisobutylenes via cationic copolymerization of p-chloromethylstyrene and isobutylene>, COA of Formula: C9H9Cl, the main research area is branched chloromethylstyrene polyisobutylene cationic copolymerization polydispersity kinetics.

Branched polyisobutylenes (PIBs) with relatively low dispersities (1.4-1.8) and benzylic halide functionalities are synthesized by self-condensing vinyl cationic copolymerization of p-chloromethylstyrene (p-CMS) and isobutylene (IB) coinitiated by TiCl4. It is found that the [IB]/[p-CMS] feed ratio plays a crucial role for the initiating behavior of p-CMS: the initiation arising from p-CMS is suppressed at [IB]/[p-CMS] ≥17; in contrast, the pendant benzyl chloride moiety of p-CMS monomer in the formed copolymer chains can initiate branching reactions. The resulting branched PIBs are of a gradient composition as well as a gradual increase in branching d. due to large disparity in reactivity ratios. This strategy is successfully employed to create branched PIBs with low to moderate mol. weights (Mn, 5 k-78 k Da) through controlling the monomer/initiator mole ratio. However, it is shown that this method failed to obtain branched PIBs with high Mn, bearing a complicated copolymerization mechanism.

Gomez-Lechon, Maria Jose; Tolosa, Laia; Castell, Jose V.; Donato, Maria Teresa published the artcile< Mechanism-based selection of compounds for the development of innovative in vitro approaches to hepatotoxicity studies in the LIINTOP project>, Product Details of C7H17Cl2N2O3P, the main research area is development innovative hepatotoxicity LIINTOP project.

The 6th European Framework Program project LIINTOP was specifically raised to optimize and provide established protocols and exptl. in vitro models for testing intestinal and liver absorption, metabolism and toxicity of mols. of pharmacol. interest. It has been focused on some of the most promising existing liver and intestine in vitro models with the aim of further improving their performance and thus taking them to a pre-normative research stage. Regarding the specific area of the liver, a first basic approach was the optimization of in vitro hepatic models and the development and optimization of in vitro approaches for toxicity screening. New advanced technologies have been proposed and developed in order to determine cellular and mol. targets as endpoints of drug exposure. A key issue in the development and optimization of in vitro hepatotoxicity screening methods was the selection of structurally diverse suitable hepatotoxic reference model compounds to be tested. To this end, a number of solid selection criteria were defined (drugs preferably than chem. agents, well-documented hepatotoxicity in man and well-defined mechanism/s of hepatotoxicity, com. available no volatile compounds with unequivocal CAS number and chem. structure), the strategy followed, including all resources consulted, is described and the selected compounds are extensively illustrated.

Sireesha, Reddymasu; Sreenivasulu, Reddymasu; Chandrasekhar, Choragudi; Jadav, Surender Singh; Pavani, Y.; Rao, Mandava Venkata Basaveswara; Subbarao, Mannam published the artcile< Design, synthesis, anti-cancer evaluation and binding mode studies of benzimidazole/benzoxazole linked β-carboline derivatives>, Formula: C8H12N2O2, the main research area is benzazolylthiazolyl carboline preparation antitumor SAR docking.

A new series of benzimidazole/benzoxazole linked β-carbolines I [X = N, O; R = H, 5,6-di-Me, 5,6-di-Br, etc.] were rationally designed and synthesized by combining two different anti-cancer fragments. The new hybrid β-carbolines I were subjected to anti-cancer screening against four different human cancer cell lines such as MCF-7 (breast), A549 (lung), Colo-205 (colon) and A2780 (ovarian) by using standard MTT assay. These hybrid β-carbolines I exhibited significant and high fold anti-cancer activity against MCF-7 cell lines than reference standard They were proved to be effective against A549 and Colo-205 cell lines. Further, compound I [X = N, R = 5,6-di-MeO, 5,6-di-Me; X = O, R = 5,6-di-Me] exhibited maximum anti-cancer activity among these hybrid β-carbolines. Later, all of the hybrid β-carbolines I were subjected to mol. interaction anal. against a few selected kinase targets such as cdc-like kinase (CLK-1 to CLK-4), epidermal growth factor reductase (EGFR) kinase, protein (ATR) kinase along with APC-Asef interface. The violin plot of binding energies of compounds I suggested them as good kinase binders. Result interpretation reported that hybrid β-carbolines I as promising CLK binders. The anti-cancer data of new hybrid β-carbolines I against MCF-7 cell lines were agreement with parent β-carboline skeleton.
