Ionic liquids coated nanocrystalline zeolite based inorganic-organic hybrid materials were synthesized. Nanocrystalline ZSM-5 zeolite was prepared under hydrothermal condition in the presence of propyltriethoxysilane as an additive in the synthesis composition of conventional ZSM-5. Ionic liquids (methylimidazolium chloride and 1-butyl-3-methylimidazolium chloride) were coated on the surface of nanocrystalline ZSM-5 by the post synthesis method. For comparative study, ionic liquids coated conventional ZSM-5 based inorganic-organic hybrid materials were also prepared Ionic liquids coated nanocrystalline ZSM-5/ZSM-5 modified electrodes were constructed for the simultaneous determination of all four DNA bases such as adenine, cytosine, guanine, and thymine. Difference in the electro-catalytic activity of the modified electrode is explained with the help of textural properties, conductivity, and d. functional theory. The anal. performance of the proposed method was demonstrated in the simultaneous determination of all four DNA bases in calf thymus DNA sample.

Ionic Liquid Mixtures-An Analysis of Their Mutual Miscibility was written by Omar, Salama;Lemus, Jesus;Ruiz, Elia;Ferro, Victor R.;Ortega, Juan;Palomar, Jose. And the article was included in Journal of Physical Chemistry B in 2014.Name: 1-Methyl-3-propylimidazolium Chloride This article mentions the following:

The use of ionic liquid mixtures (IL-IL mixtures) is being investigated for fine solvent properties tuning of the IL-based systems. The scarce available studies, however, evidence a wide variety of mixing behaviors (from almost ideal to strongly nonideal), depending on both the structure of the IL components and the property considered. In fact, the adequate selection of the cations and anions involved in IL-IL mixtures may ensure the absence or presence of two immiscible liquid phases. In this work, a systematic computational study of the mixing behavior of IL-IL systems is developed by means of COSMO-RS methodol. Liquid-liquid equilibrium (LLE) and excess enthalpy (H^E) data of more than 200 binary IL-IL mixtures (including imidazolium-, pyridinium-, pyrrolidinium-, ammonium-, and phosphonium-based ILs) are calculated at different temperatures, comparing to literature data when available. The role of the interactions between unlike cations and anions on the mutual miscibility/immiscibility of IL-IL mixtures was analyzed. On the basis of proposed guidelines, a new class of immiscible IL-IL mixtures was reported, which only is formed by imidazolium-based compounds In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Name: 1-Methyl-3-propylimidazolium Chloride).

1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8) belongs to imidazole derivatives.

Syntheses, protonation constants and antimicrobial activity of 2-substituted N-alkylimidazole derivatives was written by Kleyi, Phumelele;Walmsley, Ryan S.;Gundhla, Isaac Z.;Walmsley, Tara A.;Jauka, Tembisa I.;Dames, Joanna;Walker, Roderick B.;Torto, Nelson;Tshentu, Zenixole R.. And the article was included in South African Journal of Chemistry in 2012.Computed Properties of C11H20N2 This article mentions the following:

A series of N-alkylimidazole-2-carboxylic acid, N-alkylimidazole-2-carboxaldehyde and N-alkylimidazole-2-methanol derivatives [alkyl = benzyl, Me, Et, Pr, Bu, heptyl, octyl and decyl] have been synthesized and the protonation constants determined The antimicrobial properties of the compounds were tested against Gram-neg. (Escherichi coli), Gram-pos. (Staphylococcus aureus & Bacillus subtilis subsp. spizizenii) bacterial strains and yeast (C. albicans). Both the disk diffusion and broth microdilution methods for testing the antimicrobial activity showed that N-alkylation of imidazole with longer alkyl chains and the substitution with low pK_a group at 2-position resulted in enhanced antimicrobial activity. Particularly, the N-alkylimidazole-2-carboxylic acids exhibited the best antimicrobial activity due to the low pK_a of the carboxylic acid moiety. Generally, all the N-alkylimidazole derivatives were most active against the Gram-pos. bacteria [S. aureus (MIC = 5-160 μg mL^-1) and B. subtilis subsp. spizizenii (5-20 μg mL^-1)], with the latter more susceptible. All the compounds showed poor antimicrobial activity against both Gram-neg. (E. coli, MIC = 0.15 to >2500 μg mL^-1) bacteria and all the compounds were inactive against the yeast (Candida albicans). In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Computed Properties of C11H20N2).

1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.Computed Properties of C11H20N2

Novel drug discovery platform for spinocerebellar ataxia, using fluorescence technology targeting β-III-spectrin was written by Rebbeck, Robyn T.;Andrick, Anna K.;Denha, Sarah A.;Svensson, Bengt;Guhathakurta, Piyali;Thomas, David D.;Hays, Thomas S.;Avery, Adam W.. And the article was included in Journal of Biological Chemistry in 2021.Quality Control of 1-(((Cyclohexyloxy)carbonyl)oxy)ethyl 1-((2′-(2H-tetrazol-5-yl)-[1,1′-biphenyl]-4-yl)methyl)-2-ethoxy-1H-benzo[d]imidazole-7-carboxylate This article mentions the following:

Numerous diseases are linked to mutations in the actin-binding domains (ABDs) of conserved cytoskeletal proteins, including β-III-spectrin, α-actinin, filamin, and dystrophin. A β-III-spectrin ABD mutation (L253P) linked to spinocerebellar ataxia type 5 (SCA5) causes a dramatic increase in actin binding. Reducing actin binding of L253P is thus a potential therapeutic approach for SCA5 pathogenesis. Here, we validate a high-throughput screening (HTS) assay to discover potential disrupters of the interaction between the mutant β-III-spectrin ABD and actin in live cells. This assay monitors FRET between fluorescent proteins fused to the mutant ABD and the actin-binding peptide Lifeact, in HEK293-6E cells. Using a specific and high-affinity actin-binding tool compound, swinholide A, we demonstrate HTS compatibility with an excellent Zâ€?factor of 0.67 ± 0.03. Screening a library of 1280 pharmacol. active compounds in 1536-well plates to determine assay robustness, we demonstrate high reproducibility across plates and across days. We identified nine Hits that reduced FRET between Lifeact and ABD. Four of those Hits were found to reduce Lifeact cosedimentation with actin, thus establishing the potential of our assay for detection of actin-binding modulators. Concurrent to our primary FRET assay, we also developed a high-throughput compatible counter screen to remove undesirable FRET Hits. Using the FRET Hits, we show that our counter screen is sensitive to undesirable compounds that cause cell toxicity or ABD aggregation. Overall, our FRET-based HTS platform sets the stage to screen large compound libraries for modulators of β-III-spectrin, or disease-linked spectrin-related proteins, for therapeutic development. In the experiment, the researchers used many compounds, for example, 1-(((Cyclohexyloxy)carbonyl)oxy)ethyl 1-((2′-(2H-tetrazol-5-yl)-[1,1′-biphenyl]-4-yl)methyl)-2-ethoxy-1H-benzo[d]imidazole-7-carboxylate (cas: 145040-37-5Quality Control of 1-(((Cyclohexyloxy)carbonyl)oxy)ethyl 1-((2′-(2H-tetrazol-5-yl)-[1,1′-biphenyl]-4-yl)methyl)-2-ethoxy-1H-benzo[d]imidazole-7-carboxylate).

Polysulfone-ionic liquid based membranes for CO₂/N₂ separation with tunable porous surface features was written by Lu, Soon-Chien;Khan, Asim Laeeq;Vankelecom, Ivo F. J.. And the article was included in Journal of Membrane Science in 2016.Reference of 404001-48-5 This article mentions the following:

A surprisingly simple, yet effective blending method for ionic liquids (ILs) and polysulfone (PSf) is presented in this paper. Not only is the IL properly immobilized in the polymer matrix, which is crucial in high-pressure gas separation applications, but this method also produces tunable porous surfaced membranes that can be useful in several other applications. The size and distribution of the pores are dependent on the type and amount of IL incorporated into the PSf. A membrane formation mechanism is proposed to explain the presence of such a regular surface pore structure. Several com. available ILs were tested to examine their compatibility with the polymer, and the CO₂/N₂ gas separation performance of the resulting membrane was screened. ATR-FTIR spectroscopy, FTIR microscopy, and SEM imaging were also employed to shed light on the observed membrane structures.
