Idebenone inhibits insulin-dependent association of Shc with insulin receptor in living cells was written by Tomilov, Alexey;Allen, Sonia;Hui, Chun Kiu;Bettaieb, Ahmed;Cortopassi, Gino. And the article was included in Pharmacological Research in 2018.Formula: C33H34N6O6 This article mentions the following:

When insulin binds insulin receptor, IRS1 signaling is stimulated to trigger the maximal insulin response. P52Shc protein competes directly with IRS1, thus damping and diverting maximal insulin response. Genetic reduction of p52Shc minimizes competition with IRS1, and improves insulin signaling and glucose control in mice, and improves pathophysiol. consequences of hyperglycemia. Given the multiple benefits of Shc reduction in vivo, the author investigated whether any of 1680 drugs used in humans may function as Shc inhibitors, and thus potentially serve as novel anti-diabetics. Of the 1680, 30 insulin sensitizers were identified by screening in vitro, and of these 30, the author demonstrated that 7 bound Shc protein. Of the 7 drugs, idebenone dose-dependently bound Shc protein in the 50-100 nM range, and induced insulin sensitivity and cytoprotection in this same 100 nM range that clin. dosed idebenone reaches in human plasma. By contrast the author observes mitochondrial effects of idebenone in the 5,000 nM range that are not reached in human dosing. Multiple assays of target engagement demonstrate that idebenone phys. interacts with Shc protein. Idebenone sensitizes mice to insulin in two different mouse models of prediabetes. Genetic depletion of idebenone’s target eliminates idebenone’s ability to insulin-sensitize in vivo. Thus, idebenone is the first-in-class member of a novel category of insulin-sensitizing and cytoprotective agents, the Shc inhibitors. Idebenone is an approved drug and could be considered for other indications such as type 2 diabetes and fatty liver disease, in which insulin resistance occurs. 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: 145040-37-5Formula: C33H34N6O6).

M.;Jennings, Julia J.;Franz, Annaliese K.. And the article was included in Journal of Organic Chemistry in 2021.SDS of cas: 1632-83-3 This article mentions the following:

The hydrogen-bond-accepting abilities for more than 100 organic mols. are quantified using ¹⁹F and ³¹P NMR spectroscopy with pentafluorobenzoic acid (PFBA) and phenylphosphinic acid (PPA) as com. available, inexpensive probes. Anal. of pyridines and anilines with a variety of electronic modifications demonstrates that changes in NMR shifts can predict the secondary effects that contribute to H-bond-accepting ability, establishing the ability of PFBA and PPA binding to predict electronic trends. The H-bond-accepting abilities of various metal-chelating ligands and organocatalysts are also quantified. The measured Δδ(³¹P) and Δδ_p(¹⁹F) values correlate strongly with Hammett parameters, pK_a of the protonated HBA, and proton-transfer basicity (pK_BH+). In the experiment, the researchers used many compounds, for example, 1-Methylbenzimidazole (cas: 1632-83-3SDS of cas: 1632-83-3).

1-Methylbenzimidazole (cas: 1632-83-3) belongs to imidazole derivatives. Imidazole derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. 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.SDS of cas: 1632-83-3

Protic Ionic-Liquid-Supported Activated Carbon with Hierarchical Pores for Efficient NH₃ Adsorption was written by Yu, Min;Zeng, Shaojuan;Wang, Zongxu;Hu, Zongyuan;Dong, Haifeng;Nie, Yi;Ren, Baozeng;Zhang, Xiangping. And the article was included in ACS Sustainable Chemistry & Engineering in 2019.Quality Control of 1-Methyl-1H-imidazol-3-ium chloride This article mentions the following:

Ionic liquids (ILs) provide a new way for efficient separation and recovery of NH₃ because of low vapor pressure and adjustable properties. However, high viscosity or solid state of functionalized ILs at ambient temperature makes them impossible to use in traditional scrubbing processes. Therefore, combining ILs with porous solid materials to form novel IL-supported materials for NH₃ adsorption is an effective method to solve the above problem. In this work, three protic ILs (PILs) including imidazolium bis(trifluoromethylsulfonyl)imide ([Im][NTf₂]), 1-methylimidazolium bis(trifluoromethylsulfonyl)imide ([1-Mim][NTf₂]), and 2-methylimidazolium bis(trifluoromethylsulfonyl)imide ([2-Mim][NTf₂]) were supported onto activated carbon (AC) to prepare PIL-supported materials. The effects of PILs and AC types, PIL loadings, temperatures, and partial pressures on NH₃ adsorption, as well as the recyclability of the PIL-supported materials, were investigated in detail. Among the investigated PIL-supported materials, 20 weight % [2-Mim][NTf₂]-supported AC-980 exhibits the higher capacity of 68.61 mg of NH₃/g of adsorbent at 303.15 K and 0.10 MPa with good NH₃ selectivity and fast adsorption rate because of the synergistic interaction of hydrogen bonding between the PIL and NH₃ and hierarchical pores, which is 30% higher than that of pure AC. Meanwhile, the PIL-supported material shows good recyclability after five cycles, implying great potentials for NH₃ separation industrial processes. In the experiment, the researchers used many compounds, for example, 1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3Quality Control of 1-Methyl-1H-imidazol-3-ium chloride).

Six long chain alkyl mono- and bi-cationic imidazolium based salts with bis(trifluoromethylsulfonyl)imide (NTf₂^–) as the anion were synthesized and characterized. The single crystal structure of 1-methyl-3-octadecylimidazolium bis(trifluoromethylsulfonyl)imide could be obtained by x-ray anal.

Effect of the alkyl chain length in 1-alkyl-3-methylimidazolium ionic liquids on inter-molecular interactions and rotational dynamics was written by Garaga, Mounesha N.;Nayeri, Moheb;Martinelli, Anna. And the article was included in Journal of Molecular Liquids in 2015.Application of 404001-48-5 This article mentions the following:

We have investigated the effect of increasing the alkyl chain length, n, in 1-alkyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (C_nC₁ImTFSI) ionic liquids on both inter-mol. interactions and rotational dynamics. This has been addressed by combining 1D ¹H and T₁ relaxation NMR spectroscopy with vibrational spectroscopy, including both Raman and IR. We find that the vibrational modes sensitive to inter-mol. interactions change only slightly with an increased alkyl chain length, with negligible changes for chains longer than the hexyl (n > 6). This is nicely corroborated by ¹H chem. shift changes, in particular of the aromatic protons. The ¹³C correlation times, τ_c, of the individual carbon atoms reveal that while the overall rotational mobility decreases with n, different dynamical properties are observed with the polar domains becoming the most dynamic and the imidazolium ring and its closest chain segment the most rigid. We conclude that the formation of segregated nano-domains in C_nC₁ImTFSI is accompanied by the formation of nano-dynamical heterogeneities, which can explain why classical theories fail to describe the dependence on n of macroscopically observed properties.

Following our recent report showing the potential of naturally occurring aurones (2-benzylidenebenzofuran-3(2H)-ones) as anti-hepatitis C virus (HCV) agents, efforts were continued in order to refine the structural requirements for the inhibitory effect on HCV RNA-dependent RNA polymerase (RdRp). In this study, we targeted the B-ring moiety of aurones with the aim to improve structural features associated with higher inhibition of the targeted polymerase. In vitro evaluation of the RdRp inhibitory activity of the 37 newly synthesized compounds pointed out that the replacement of the B-ring with an N-substituted indole moiety induced the highest inhibitory effect. Of these, compounds 31, 40 and 41 were found to be the most active (IC₅₀ = 2.3-2.4 μM). Docking experiments performed with the most active compounds revealed that the allosteric thumb pocket I of RdRp is the binding pocket for aurone analogs.
