The straightforward synthesis of aminoribosyl uridines substituted by a 5′-methylene-urea is described. 90Their convergent synthesis involves the urea formation from various activated amides and an azidoribosyl uridine substituted at the 5′ position by an aminomethyl group. This common intermediate resulted from the diastereoselective glycosylation of a phthalimido uridine derivative with a ribosyl fluoride as a ribosyl donor. The inhibition of the MraY transferase activity by the synthesized 11 urea-containing inhibitors was evaluated and 10 compounds revealed MraY inhibition with IC50 ranging from 1.9μM to 16.7μM. Their antibacterial activity was also evaluated on a panel of Gram-pos. and Gram-neg. bacteria. Four compounds exhibited a good activity against Gram-pos. bacterial pathogens with MIC ranging from 8 to 32μg mL-1, including methicillin resistant Staphylococcus aureus (MRSA) and Enterococcus faecium. Interestingly, one compound also revealed antibacterial activity against Pseudomonas aeruginosa with MIC equal to 64μg mL-1. Docking experiments predicted two modes of positioning of the active compounds urea chain in different hydrophobic areas (HS2 and HS4) within the MraY active site from Aquifex aeolicus. However, mol. dynamics simulations showed that the urea chain adopts a binding mode similar to that observed in 5CKR structural model and targets the hydrophobic area HS2. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).Computed Properties of 574-98-1

And the article contained the following:

Herein, we report the development of new Co complexes that have cyclopropane-based diphosphine ligands and can catalyze highly chemo-, regio-, and stereoselective hydroboration reactions of unsym. internal alkynes. These reactions exhibited unusual regioselectivity: specifically, reactions of aryl alkyl internal alkynes showed excellent cis-β-addition selectivity, and reactions of dialkyl internal alkynes gave excellent cis-α-addition selectivity. Highly regioselective hydroboration of unsym. dialkyl internal alkynes cannot be achieved by other known methods. The reactions described herein are highly synthetically useful, particularly for the stereoselective synthesis of trisubstituted alkenylborates and alkenes. Mechanistic studies indicate that a CoI-H species is a plausible active catalyst and the rigid structure of the cyclopropane skeleton of the ligands and the crowded reaction pocket were responsible for the unprecedented regioselectivity.

Jin, Rong;Liu, Guorui;Jiang, Xiaoxu;Liang, Yong;Fiedler, Heidelore;Yang, Lili;Zhu, Qingqing;Xu, Yang;Gao, Lirong;Su, Guijin;Xiao, Ke;Zheng, Minghui research published �Profiles, sources and potential exposures of parent, chlorinated and brominated polycyclic aromatic hydrocarbons in haze associated atmosphere� the research content is summarized as follows. Profiles, sources, and potential exposures of chlorinated and brominated polycyclic aromatic hydrocarbons (ClPAH, BrPAH) in haze associated atm. remain unclear. Haze events occur frequently during the heating period in Beijing, China, and provide a typical urban context to assess concentrations, profiles, sources, and potential exposure to ClPAH, BrPAH, and their non-halogenated parent compounds (PAH) in air. Average PAH, ClPAH, and BrPAH concentrations during heating periods (with more frequent haze events) were �-9 times higher than during non-heating periods. Particulate matter (PM)-associated ClPAH and BrPAH concentrations were higher in heating vs. non-heating periods; for gas-associated ClPAH and BrPAH, this distinction was not significant. Congener patterns and profiles indicated that with increasing coal combustion in the heating period, PAH and ClPAH concentrations in air were elevated vs. the non-heating period. Inhalation of PM-associated PAH, ClPAH, and BrPAH accounted for higher exposure than inhalation of gas phase and dermal contact of gaseous and particulate phases. Results determined the particulate phase is the dominant exposure pathway for atm. PAH, ClPAH, and BrPAH during haze events, which is different from previous studies.

Jin, Rong;Liu, Guorui;Zheng, Minghui;Jiang, Xiaoxu;Zhao, Yuyang;Yang, Lili;Wu, Xiaolin;Xu, Yang research published �Secondary Copper Smelters as Sources of Chlorinated and Brominated Polycyclic Aromatic Hydrocarbons� the research content is summarized as follows. The generation and extent to which chlorinated and brominated polycyclic aromatic hydrocarbons (Cl/Br-PAH) are formed and released from secondary Cu smelters are unknown. This field study is the first to identify secondary Cu smelters as new Cl/Br-PAH sources. Mass concentrations of �sub>19Cl-PAH and �sub>19Br-PAH were 5.8-271 ng/Nm3 and 0.59-52.4 ng/Nm3, resp. A comparison of Cl/Br-PAH concentrations in secondary Cu smelting flue gas and fly ash indicated that using scrap Cu as raw material or adding coal or heavy oil as reductant may contribute to increased formation and elevated emission of Cl/Br-PAH. Cl/Br-PAH congener profiles in secondary Cu smelting flue gas and fly ash were different than those from waste incinerators and other previously reported sources; thus, they could be used as possible fingerprints and source apportionments for environmental Cl/Br-PAH. Atm. Cl/Br-PAH concentrations in the workplace or smelter surroundings were determined and potential exposure was assessed. Although chlorination of PAH was previously recognized as an important Cl/Br-PAH formation pathway, this was not verified to be the major Cl/Br-PAH formation pathway for secondary Cu smelters in this work.

Jin, Rong;Yang, Lili;Zheng, Minghui;Xu, Yang;Li, Cui;Liu, Guorui research published ã€?Source identification and quantification of chlorinated and brominated polycyclic aromatic hydrocarbons from cement kilns co-processing solid wastesã€? the research content is summarized as follows. Chlorinated and brominated polycyclic aromatic hydrocarbons (Cl/Br-PAHs) are widespread persistent organic pollutants (POPs) in environments. Identifying the new sources of Cl/Br-PAHs is important for implementing source control and reducing environmental risk. Although co-processing of solid wastes by cement kilns increased recently, the occurrences and characteristics of Cl/Br-PAHs as emerging POPs during cement kiln co-processing solid wastes have not been investigated. This study firstly investigated the occurrences, characteristics, and variations of Cl/Br-PAHs from four cement kilns co-processing different solid wastes. The concentration ranges of Cl-PAHs and Br-PAHs in stack gas samples from the investigated cement kilns were 15.6-94.1 ng m-3 and 1.04-4.28 ng m-3, resp. Emission factors of Cl-PAHs and Br-PAHs through stack gases were 29.9-275μg t-1 and 3.0-8.3μg t-1, resp. Variations of Cl/Br-PAHs in particle samples collected from different process stages within the cement kiln system indicated that the kiln end was the major formation zone for Cl/Br-PAHs. Congener profiles of Cl/Br-PAHs varied with the co-processed solid waste types, indicating the important influence of raw material compositions Calculations of net emissions of Cl/Br-PAHs within the cement kiln systems suggested efficient destruction (87.6%-98.8%) of Cl/Br-PAHs by the cement kilns.

Jiao, Xinyue;Marin, Luminita;Cheng, Xinjian research published ã€?Fluorescent cellulose/testing paper for the sensitive and selective recognition of explosives 2,4,6-trinitrophenol and 2,4-dinitrophenylhydrazineã€? the research content is summarized as follows. 2,4,6-trinitrophenol (TNP) and 2,4-dinitrophenylhydrazine (DNH) are harmful to the environment and human beings. Trace detection of TNP and DNH is worth of developing facile methods. In this work, cellulose powder and filter paper based fluorescence sensor are synthesized. Firstly, NH2CH2CH2– was introduced into cellulose through etherification reaction, and at the same time, a small mol. BODIPY with -CHO was synthesized. Then BODIPY was incorporated into cellulose by Schiff base reaction to obtain fluorescent macromol. probes. These fluorescent cellulose sensors can efficiently identify TNP and DNH, with the lowest detection limits of 2.8 x 10-7 M and 1.6 x 10-7 M, resp. Fluorescent filter paper is obtained via the same route. They also exhibit TNP and DNH identification ability. The method developed in filter paper not only expands the application range of cellulose, but also can efficiently identify the pollutants TNP and DNH, which is of great significance in theory and practical applications.
