Can Medical-Grade Gloves Provide Protection after Repeated Disinfection?

The advent of the COVID-19 pandemic has generated an increased consumption of personal protective equipment (PPE), including gloves and masks, by healthcare workers and by the general public at a global scale. This has generated substantial shortage of these single-use and disposable PPEs that will end up as a landfill waste. Extending the life cycle of PPEs, such as gloves, by disinfecting treatments could help mitigate these concerns. However, the effect of various disinfection treatments on the functionality of gloves is unknown. In this study, six commonly used viral disinfection treatment methods (i.e., ultraviolet (UV) radiation, dry heat, steam, alcohol, chlorine compounds, and quaternary ammonium compounds) were evaluated for their effect on the performance attributes of two commonly used medical-grade gloves and nitrile and vinyl (latex) gloves. The barrier properties of both gloves against water and ethanol vapor flux were not affected up to 10 cycles of disinfection cycles. However, the increase in the disinfection cycle from 10 to 20 slightly reduced their barrier properties with minor variation in the type of disinfection and glove type. Infrared spectroscopy and microscopy investigations confirmed that both types of gloves could withstand up to 20 cycles of disinfection treatments with no observable change in the chemical structure and surface morphology of the disinfected surfaces, respectively. Lastly, tear property testing of the gloves indicated little to no change from the baseline after 20 cycles of treatment in both the nitrile and vinyl-based gloves. Overall, this study indicated that alcohol, UV, and heat treatment could be acceptable disinfection methods that allow the reuse of gloves up to 20 cycles. Such repeated disinfection of gloves not only reduces the strain on the supply of gloves but also decreases the postconsumer landfilled waste and environmental footprint of gloves.

TBHP/TBAI-Mediated Oxidative Cascade Reaction Consisting of Dimerization, Cyclization, and 1,2-Aryl Migration: Metal-Free Synthesis of Pyrrolin-4-ones and Highly Substituted Pyrroles

Treatment of enamino esters with TBHP (t-butylhydroperoxide) and TBAI (t-butylammonium iodide) in HFIP (hexafluoroisopropanol) was found to afford a variety of substituted pyrrolin-4-one compounds. This metal-free oxidative cascade reaction consists of the key steps of coupling of two radical intermediates, an intramolecular ring closure, and an exclusive 1,2-aryl radical migration. Upon treatment with a base, the obtained pyrrolin-4-ones could be converted to the highly substituted pyrrole compounds.

Lewis Acid Mediated Addition of Indoles and Alcohols to Tetronic Acid and Tetramic Acids

The electrophilic substitution of indoles with tetronic acid and N-acetyltetramic acid mediated by BF3OEt2 was investigated. This strategy allowed for the preparation of nine indole-substituted furan-2-ones (indolyl–lactones) and 3-pyrrolin-2-ones (indolyl–lactams) and is more straightforward than previously reported synthetic methods. During the course of our investigation, we also discovered a facile synthesis of tetronates and a tetramate via a BF3-mediated addition of alcohols to tetronic acid and N-acetyltetramic acid, respectively.

A lithium solid electrolyte of acrylonitrile copolymer with thiocarbonate moiety and its potential battery application

Researchers study the solid polymer electrolyte (SPE) to raise the safety and capacity of current lithium ion battery technology to a higher level. We opt to work on the polymer host based on acrylonitrile (PAN), since the nitrile group provides an admirable electrochemical stability and a high polarity, which are critical to the polymeric electrolyte. Yet, the nitrile group is also the origin of high glass transition temperature Tg, which requires synthetic effort s to reduce Tg through tuning the SPE composition. The RAFT mediated polymerization technique is employed to decrease the molecular weight and simultaneously incorporate a substantial amount of thiocarbonate moiety in the backbone. The synthesized PAN copolymer, molecular weight similar to 1600 g mol(-1), contains 43.3% (by mole) carbon, 2.1% sulfur, and 8.7% nitrogen. Copolymerization with dodecyl acrylate increases the free volume of host. Substitution of LiFSI for LiTFSI reduces the glass transition temperature effectively since LiFSI is easier to dissociate and more effective in plasticization. The synthesis effort s result in the highest ion conductivity 6.1 x 10(-4) S cm(-1) at room temperature and 1.1 x 10(-3) S cm(-1) at 50 degrees C. This SPE also displays a lithium transference number 0.318, a high stability when interfacing the lithium metal, and tolerates a potential window of 6.0 V. When sandwiched between lithium anode and NMC622 cathode, the cell of SPE reaches 150 mAh g(-1) in charge and discharge. (c) 2020 Elsevier Ltd. All rights reserved.

Copper- and DMF-mediated switchable oxidative C-H cyanation and formylation of imidazo[1,2-a]pyridines using ammonium iodide

The cyanation and formylation of imidazo[1,2-a]pyridines were developed under copper-mediated oxidative conditions using ammonium iodide and DMF as a nontoxic combined cyano-group source and DMF as a formylation reagent. Mechanistic studies indicate that the cyanation of imidazo[1,2-a]pyridines proceeds through a two-step sequence: initial iodination and then cyanation. The cyanation has a broad substrate scope and high functional group tolerance, and can be safely conducted on a gram scale. A novel copper-mediated formylation using the widely available DMF as the formylation reagent and environmentally friendly molecular oxygen as the oxidant has also been developed. This protocol also provided a convenient approach for the synthesis of clinically used saripidem.

Covalent Modification of Cytochrome c by Reactive Metabolites of Furan

Metabolism of the hepatotoxicant furan leads to protein adduct formation in the target organ. The initial bioactivation step involves cytochrome P450-catalyzed oxidation of furan, generating cis-2-butene-1,4-dial (BDA). BDA reacts with lysine to form pyrrolin-2-one adducts. Metabolic studies indicate that BDA also reacts with glutathione (GSH) to generate 2-(S-glutathionyl)butanedial (GSH-BDA), which then reacts with lysine to form GSH-BDA-lysine cross-links. To explore the relative reactivity of these two reactive intermediates, cytochrome c was reacted with BDA in the presence and absence of GSH. As judged by MALDI-TOF mass spectrometry, BDA reacts extensively with cytochrome c to form adducts that add 66 Da to the protein, consistent. with the formation of pyrrolinone adducts. Addition of GSH to the reaction mixture reduced the overall extent of adduct formation. The mass of the adducted protein was shifted by 355 Da as expected for GSH-BDA-protein cross-link formation. LC-MS/MS analysis of the tryptic digests of the alkylated protein indicated that the majority of adducts occurred on lysine residues, with BDA reacting less selectively than GSH-BDA. Both types of adducts may contribute to the toxic effects of furan.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.

A loop resonator for slice-selective in vivo EPR imaging in rats

A loop resonator was developed for 300 MHz continuous-wave electron paramagnetic resonance (CW-EPR) spectroscopy and imaging in live rats. A single-turn loop (55 mm in diameter) was used to provide sufficient space for the rat body. Efficiency for generating a radiofrequency magnetic field of 38 mu T/W-1/2 was achieved at the center of the loop. For the resonator itself, an unloaded quality factor of 430 was obtained. When a 350 g rat was placed in the resonator at the level of the lower abdomen, the quality factor decreased to 18. The sensitive volume in the loop was visualized with a bottle filled with an aqueous solution of the nitroxide spin probe 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy (3-CP). The resonator was shown to enable EPR imaging in live rats. Imaging was performed for 3-CP that had been infused intravenously into the rat and its distribution was visualized within the lower abdomen. (c) 2007 Elsevier Inc. All rights reserved.
