Lei, Yuting;Zhang, Guihua;Zhang, Qinglan;Yu, Ling;Li, Hua;Yu, Haili;He, Yi research published 《 Visualization of gaseous iodine adsorption on single zeolitic imidazolate framework-90 particles》, the research content is summarized as follows. Zeolitic imidazolate frameworks (ZIFs) are very useful as high-capacity iodine (I2) adsorbents. The adsorption performance is usually probed by measuring a statistical average property over an entire sample consisting of a large number of ZIF particles, leaving the interparticle heterogeneity information among individuals. Here we report a dark-field microscopy (DFM) method to visualize gaseous I2 adsorption on single ZIF-90 particles in situ and in real time. The adsorption of I2 is found to alter the scattering spectrum of ZIF-90 particles, inducing a distinct color change from bluewhite to yellow. According to correlating the adsorption amount of gaseous I2 with the change of B value from DFM images, we quant. image the adsorption process and estimate the related kinetic parameters at the single particle level. Single particle measurements clarify the large particle-to-particle heterogeneity in adsorption reactivity and significant adsorption activity improvement of ZIF-90 after introduction of linker defects, which provides a microscopic understanding of the structure-activity relationship. We further demonstrate the capacity of this strategy for studying gaseous I2 adsorption on single ZIF-91 particle as a derivative of ZIF-90 to illustrate the generality.

Lehotay, Steven J. research published 《 Comparison of analyte identification criteria and other aspects in triple quadrupole tandem mass spectrometry: Case study using UHPLC-MS/MS for regulatory analysis of veterinary drug residues in liquid and powdered eggs》, the research content is summarized as follows. Ultrahigh-performance liquid chromatog. (UHPLC) coupled with triple quadrupole tandem mass spectrometry (MS/MS) is one of the most powerful tools for the multiclass, multiresidue anal. of veterinary drugs, pesticides, mycotoxins, and other chem. contaminants in foods and other sample types. Until approx. 2010, com. MS/MS instruments using multiple reaction monitoring (MRM) were generally limited to min. dwell (and inter-dwell) times of 10 ms per ion transition. To achieve the needed accuracy and detection limits for hundreds of targeted analytes, older UHPLC-MS/MS methods typically acquired only two ion transitions per analyte (yielding only one ion ratio for qual. identification purposes), which is still the norm despite technol. advancements. Newer instruments permit as little as 1 ms (inter-)dwell times to afford monitoring of more MRMs/analyte with minimal sacrifices in accuracy and sensitivity. In this study, quantification and identification were assessed in the validation of 169 veterinary drugs in liquid and powd. eggs. Quant., an “extract-and-inject” sample preparation method yielded acceptable 70-120% recoveries and < 25% RSD for 139-141 (82-83%) of the 169 diverse drug analytes spiked into powd. and liquid eggs, resp., at three levels of regulatory interest. Qual., rates of false positives and negatives were compared when applying three different regulatory identification criteria in which two or three MRMs/drug were used in each case. Independent of the identification criteria, rates of false positives remained <10% for 95-99% of the drugs whether 2 or 3 ions were monitored, but the percent of drugs with >10% false negatives decreased from 25-45 to 10-12% when using 2 vs. 3 MRMs/analyte, resp. Use of a concentration threshold at 10% of the regulatory level as an identification criterion was also very useful to reduce rates of false positives independent of ion ratios. Based on these results, monitoring >2 ion transitions per analyte is advised when using MS/MS for anal., independent of SANTE/12682/2019, FDA/USDA, or 2002/657/EC identification criteria. (Quant)identification results using all three criteria were similar, but the SANTE criteria were advantageous in their greater simplicity and practical ease of use.

Lee, Yun-Yang;Penley, Drace;Klemm, Aidan;Dean, William;Gurkan, Burcu research published 《 Deep Eutectic Solvent Formed by Imidazolium Cyanopyrrolide and Ethylene Glycol for Reactive CO₂ Separations》, the research content is summarized as follows. Solvents made from a reactive ionic liquid, with an imidazolium cation and pyrrolide anion, and ethylene glycol at a wide compositional range were studied for separations of CO₂ at low partial pressures (≪0.1 bar up to 1 bar). Thermal anal. and measurements of viscosity and d. show compacting of the liquid upon mixing with enhanced stability achieved by hydrogen bonding. A detailed mechanistic study was performed by IR, quant. NMR, and ab initio calculations that show significant CO₂ absorption capacity below 5000 ppm of CO₂ in N₂. Three reversible routes are found that yield carbonate (major product), carboxylate (moderate), and carbamate (minor) species. With CO₂ at 100% RH, bicarbonate along with carbonate species form. The CO₂-ethlyene glycol reaction complex, the carbonate anion, is stabilized by the hydrogen bonding and Coulombic interactions, thus preventing evaporation of the solvent during regeneration. This study demonstrates a promising approach to designer green solvents for CO₂ separations in open systems such as direct air capture. Functional solvents with very low volatility are demonstrated for reactive CO₂ separations suitable for direct air capture.

Lee, Sumin;Chung, Clive Yik-Sham;Liu, Pei;Craciun, Laura;Nishikawa, Yuki;Bruemmer, Kevin J.;Hamachi, Itaru;Saijo, Kaoru;Miller, Evan W.;Chang, Christopher J. research published 《 Activity-Based Sensing with a Metal-Directed Acyl Imidazole Strategy Reveals Cell Type-Dependent Pools of Labile Brain Copper》, the research content is summarized as follows. Copper is a required nutrient for life and particularly important to the brain and central nervous system. Indeed, copper redox activity is essential to maintaining normal physiol. responses spanning neural signaling to metabolism, but at the same time copper misregulation is associated with inflammation and neurodegeneration. As such, chem. probes that can track dynamic changes in copper with spatial resolution, especially in loosely bound, labile forms, are valuable tools to identify and characterize its contributions to healthy and disease states. The authors present an activity-based sensing (ABS) strategy for copper detection in live cells that preserves spatial information by a copper-dependent bioconjugation reaction. Specifically, the authors designed copper-directed acyl imidazole dyes that operate through copper-mediated activation of acyl imidazole electrophiles for subsequent labeling of proximal proteins at sites of elevated labile copper to provide a permanent stain that resists washing and fixation. To showcase the utility of this new ABS platform, the authors sought to characterize labile copper pools in the three main cell types in the brain: neurons, astrocytes, and microglia. Exposure of each of these cell types to physiol. relevant stimuli shows distinct changes in labile copper pools. Neurons display translocation of labile copper from somatic cell bodies to peripheral processes upon activation, whereas astrocytes and microglia exhibit global decreases and increases in intracellular labile copper pools, resp., after exposure to inflammatory stimuli. This work provides foundational information on cell type-dependent homeostasis of copper, an essential metal in the brain, as well as a starting point for the design of new activity-based probes for metals and other dynamic signaling and stress analytes in biol.

Renuka;White, Kris M.;Garcia-Sastre, Adolfo;Ott, Melanie;Sirota, Marina research published 《 Transcriptomics-based drug repositioning pipeline identifies therapeutic candidates for COVID-19》, the research content is summarized as follows. Abstract: The novel SARS-CoV-2 virus emerged in Dec. 2019 and has few effective treatments. We applied a computational drug repositioning pipeline to SARS-CoV-2 differential gene expression signatures derived from publicly available data. We utilized three independent published studies to acquire or generate lists of differentially expressed genes between control and SARS-CoV-2-infected samples. Using a rank-based pattern matching strategy based on the Kolmogorov-Smirnov Statistic, the signatures were queried against drug profiles from Connectivity Map (CMap). We validated 16 of our top predicted hits in live SARS-CoV-2 antiviral assays in either Calu-3 or 293T-ACE2 cells. Validation experiments in human cell lines showed that 11 of the 16 compounds tested to date (including clofazimine, haloperidol and others) had measurable antiviral activity against SARS-CoV-2. These initial results are encouraging as we continue to work towards a further anal. of these predicted drugs as potential therapeutics for the treatment of COVID-19.

La Vecchia, Carlo;Turati, Federica;Negri, Eva research published 《 Exposure to antithyroid drugs and ethylenethiourea and risk of thyroid cancer: a systematic review of the epidemiologic evidence》, the research content is summarized as follows. The thyroid peroxidase inhibiting compounds methimazole, methylthiouracil, propylthiouracil, thiouracil (i.e. ‘antithyroid’ drugs) and ethylenethiourea have been associated to thyroid tumors in rodents. According to a systematic review by the International Agency for Research on Cancer (IARC) published in 2000, evidence for the human carcinogenicity was inadequate. We performed an up-to-date systematic review of human epidemiol. studies on the association between such compounds and thyroid cancer incidence or mortality. The literature research (1999-March 2020) identified four relevant articles. Considering also reports from the previous IARC review, this systematic review considered seven reports (five distinct studies) on antithyroid drugs and two on ethylenethiourea. As for antithyroid drugs, three reports based on different follow-ups gave results from a cohort of patients treated for hyperthyroidism in 1946-1964. In the earlier report, thyroid cancer incidence was higher in patients primarily treated with antithyroid drugs (3.2/1000) than in those originally treated with thyroidectomy (0.34/1000) or radioactive iodine (0.88/1000), which can be explained by the higher frequency of subsequent thyroidectomy, and hence the higher chance of cancer detection, in that group (30 vs. 0.5 and 1.2%). The two subsequent reports found no deaths from thyroid cancer among patients treated exclusively with antithyroid drugs through 1990 and 2014. A nested case-control study found an odds ratio (OR) of thyroid cancer of 2.79 [95% confidence interval (CI), 0.78-10.02, from a 2-yr lag anal.] for =3 vs. no propylthiouracil prescriptions. The increased risk can be attributed to advanced diagnosis of an underlying cancer, as suggested by the stronger association observed in a no-lag anal. (OR, 8.03). In a historical cohort of newly diagnosed hyperthyroid patients, the hazard ratio for treatment with radioactive iodine vs. thionamides only was 0.45 (95% CI, 0.21-0.99), possibly due to the closer surveillance of patients receiving thionamides only. Two case-control studies did not find any association with the use of antithyroid drugs. As for ethylenethiourea, no thyroid cancer cases were found in a historical cohort of 1929 workers occupationally exposed in a 15-yr period and no association with proxies of mancozeb exposure (a fungicide whose main metabolite is ethylenethiourea) was detected in a cohort of °236 000 farmers. There is no evidence for a relevant role of either antithyroid drugs or ethylenethiourea on thyroid cancer.

It was synthesized by reacting 1,2-diaminobenzene with formaldehyde and then hydrolyzing the intermediate imidazolium salt, which is stable in acidic solutions. The complex can be prepared by mixing two solutions of imidazole and trifluoroacetic acid. The ligand has a redox potential of -0.1 V (vs NHE). This means it can be oxidized to the carbonyl group or reduced back to the imidazole ring. The compound is stable in neutral solution and forms stable complexes with metal ions such as Cu+, Fe3+, and Zn2+. It also coordinates well with oxygen atoms, nitrogen atoms, and water molecules. 1H-Imidazole-4-carbaldehyde has been shown to bind to glucocortic, Application In Synthesis of 3034-50-2

Kumar, Sunil;Singh, Sohan;Gadwal, Jitendra;Makar, Parvesh;Joshi, Hemant research published 《 Regioselective C-H arylation of imidazoles employing macrocyclic palladium(II) complex of organoselenium ligand》, the research content is summarized as follows. In this report, a new air stable bidentate selenium ligand was synthesized by the reaction of 1,8-bis(2-(chloromethyl)phenoxy)octane with sodium salt of phenylselenol. The reaction of this ligand with Pd(CH₃CN)₂Cl₂ in acetonitrile under reflux conditions resulted in 19-membered ring macrocyclic palladium(II) complex. The structure of ligand precursors, ligand, and macrocyclic palladium(II) complex were authenticated by using ¹H, ¹³C{1H} NMR spectroscopy and elemental anal. The obtained air and moisture stable, thermally robust macrocyclic palladium(II) complex was employed as catalyst for regioselective arylation of 1-methylimidazole and 1,2-dimethylimidazole with a variety of aryl bromides. The mild reaction conditions, exclusive C-5 regioselectivity, excellent yields (∼73-95%), low catalyst loading (1.5 mol%) and functional group tolerance are the advantages of this protocol. Homogeneous nature of catalysis process was confirmed with the help of mercury and triphenylphosphine poisoning tests. The catalyst can be recycled and reused with significant loss (22%) in efficiency.
