In the effort to develop novel quinoline derivatives for the treatment of liver cancer, a series of N’-substituted methylene-4-(quinoline-4-amino)benzoyl hydrazides I (R = n-Pr, 2,6-(MeO)₂C₆H₃, 1H-benzo[d]imidazole-2-yl, etc.) was synthesized and evaluated for their biol. activities as anticancer agents. Compounds I [R = 3,4-dimethoxyphenyl (II), 2,5-dihydroxyphenyl (III)] were found to be the most potent antiproliferative agents against HepG2 cell line with an IC₅₀ value of 12.6 ± 0.1μM and 27.3 ± 1.7μM, resp. Compound II also exhibited potent cytotoxicity against SMMC-7721 and Huh7 cells with IC₅₀ values of 9.6 ± 0.7μM and 6.3 ± 0.2μM, resp. Inspiringly, both II and III exhibited lower cytotoxic property in normal cells than hepatic carcinoma cells.

Lei, Zhiwen;Shen, Jinlai;Wang, Jun;Qiu, Qi;Zhang, Guangzhao;Chi, Shang-Sen;Xu, Hongli;Li, Shuai;Zhang, Weide;Zhao, Yusheng;Deng, Yonghong;Wang, Chaoyang research published 《 Composite polymer electrolytes with uniform distribution of ionic liquid-grafted ZIF-90 nanofillers for high-performance solid-state Li batteries》, the research content is summarized as follows. The stable structure, high porosity and surface functionality endow metal organic frameworks (MOFs) nanoparticles as excellent nanofillers for high-performance poly (ethyleneoxide)-based solid polymer electrolytes (PEO SPEs). However, the agglomeration of MOFs severely limits their potential applications. Herein, a novel zeolitic imidazolate framework-90 nanofiller grafted with imidazole ionic liquid containing siloxane groups (ZIF-90-g-IL) is prepared by dehydration condensation reaction, which enables the uniform distribution of the nanofiller in PEO SPEs. The resulting composite PEO SPE with ZIF-90-g-IL nanofillers delivers higher ionic conductivity of 1.17 x 10-4 S/cm at 30°C and lithium ion transference number of 0.44, wider electrochem. stability window of 4.8 V, and stronger ability to inhibit lithium dendrite growth than the PEO SPE with unmodified ZIF-90. The strong interaction of ZIF-90-g-IL with PEO is caused by the chelation of quaternary ammonium cations of ionic liquid groups on the ZIF-90-g-IL surface with oxygen containing a lone pair of electrons of PEO, resulting in a uniform distribution of the nanofillers in PEO. The LFP||Li half cells with the PEO/ZIF-90-g-IL SPE exhibit good cycling performance with 71% capacity retention (101 mAh g-1) after 500 cycles at 2C under 60°C, and show excellent cycling performance with 97.4% capacity retention (148 mAh g-1) after 30 cycles at 0.1C under 30°C. The composite SPE is also used for high-voltage NCM811||Li half cells. The capacity retention is 63% (99 mAh g-1) after 100 cycles at 0.1C under 60°C. The results imply ZIF-90-g-IL as effective nanofillers for SPEs showing a great potential application in all solid-state lithium metal batteries.

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.

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.

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.

Lakshmanan, Kaviarasan;Hemanth, Kantabathina;Krishnamurthy, Praveen T.;Rajagopal, Kalirajan;Byran, Gowramma research published 《 Design, Synthesis, and In-Vitro Biological Evaluation of PARP-1 Inhibitors Based on a 4-(Benzylideneamino)-N-(Quinolin-8-yl)Benzamide Scaffold》, the research content is summarized as follows. Novel poly(ADP-ribose)polymerase (PARP)-1 inhibitors containing, the 4-(benzylideneamino)-N-(quinolin-8-yl)benzamide moiety, were designed and synthesized. The docking study revealed that the designed compounds possess significant to moderate interaction with the targeted enzyme PARP1. Among them compound I (-52.04 K/cal) and II (-50.234 K/cal) showed similar Glidescore compared to Olaprib (-57.76 K/cal). Some of the synthesized compounds displayed good PARP-1 inhibitory activity, and among them, I and II were the most potent one. Enzyme inhibitory assay indicated that the compounds I, II, III and IV exhibited an enzyme inhibitory activity against PARP-1 enzyme similar to that of olaparib. All the synthesized compounds were screened for their in vitro anticancer activity against MCF-7 and MDA-MB-232 cell lines. Among them, compound I (60.63 μg/mL and 56.38 μg/mL) and II (368.03 μg/mL and 54.42 μg/mL) were the most potent ones. In addition, ADMET prediction results indicated that these compounds might be less toxic and display more interesting pharmacokinetic properties.
