And the article was included in Tribology Letters in 2008.Computed Properties of C7H13ClN2 This article mentions the following:

Ionic liquids (ILs) are considered as a new kind of lubricant for micro/nanoelectromech. system (M/NEMS) due to their excellent thermal and elec. conductivity However, so far, only few reports have investigated the triboltribol. behavior of mol. thin films of various ILs. Evaluating the nanoscale tribol. performance of ILs when applied as a few nanometers-thick film on a substrate is a critical step for their application in MEMS/NEMS devices. To this end, four kinds of ionic liquid carrying Me, hydroxyl, nitrile, and carboxyl group were synthesized and these mol. thin films were prepared on single crystal silicon wafer by dip-coating method. Film thickness was determined by ellipsometric method. The chem. composition and morphol. were characterized by the means of multi-technique X-ray photoelectron spectrometric anal., and at. force microscopic (AFM) anal., resp. The nano- and microtribol. properties of the ionic liquid films were investigated. The morphologies of wear tracks of IL films were examined using a 3D non-contact interferometric microscope. The influence of temperature on friction and adhesion behavior at nanoscale, and the effect of sliding frequency and load on friction coefficient, load bearing capacity, and anti-wear durability at microscale were studied. Corresponding tribol. mechanisms of IL films were investigated by AFM and ball-on-plane microtribotester. Friction reduction, adhesion resistance, and durability of IL films were dependent on their cation chem. structures, wettability, and ambient environment. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Computed Properties of C7H13ClN2).

Correction of metabolic abnormalities in a rodent model of obesity, metabolic syndrome, and type 2 diabetes mellitus by inhibitors of hepatic protein kinase C-喂 was written by Sajan, Mini P.;Nimal, Sonali;Mastorides, Stephen;Acevedo-Duncan, Mildred;Kahn, C. Ronald;Fields, Alan P.;Braun, Ursula;Leitges, Michael;Farese, Robert V.. And the article was included in Metabolism, Clinical and Experimental in 2012.HPLC of Formula: 26832-08-6 This article mentions the following:

Excessive activity of hepatic atypical protein kinase (aPKC) is proposed to play a critical role in mediating lipid and carbohydrate abnormalities in obesity, the metabolic syndrome, and type 2 diabetes mellitus. In previous studies of rodent models of obesity and type 2 diabetes mellitus, adenoviral-mediated expression of kinase-inactive aPKC rapidly reversed or markedly improved most if not all metabolic abnormalities. Here, we examined effects of 2 newly developed small-mol. PKC-喂/位 inhibitors. We used the mouse model of heterozygous muscle-specific knockout of PKC-位, in which partial deficiency of muscle PKC-位 impairs glucose transport in muscle and thereby causes glucose intolerance and hyperinsulinemia, which, via hepatic aPKC activation, leads to abdominal obesity, hepatosteatosis, hypertriglyceridemia, and hypercholesterolemia. One inhibitor, 1H-imidazole-4-carboxamide, 5-amino-1-[2,3-dihydroxy-4-[(phosphonooxy)methyl]cyclopentyl-[1R-(1a,2b,3b,4a)]], binds to the substrate-binding site of PKC-位/喂, but not other PKCs. The other inhibitor, aurothiomalate, binds to cysteine residues in the PB1-binding domains of aPKC-位/喂/味 and inhibits scaffolding. Treatment with either inhibitor for 7 days inhibited aPKC, but not Akt, in liver and concomitantly improved insulin signaling to Akt and aPKC in muscle and adipocytes. Moreover, both inhibitors diminished excessive expression of hepatic, aPKC-dependent lipogenic, proinflammatory, and gluconeogenic factors; and this was accompanied by reversal or marked improvements in hyperglycemia, hyperinsulinemia, abdominal obesity, hepatosteatosis, hypertriglyceridemia, and hypercholesterolemia. Our findings highlight the pathogenetic importance of insulin signaling to hepatic PKC-喂 in obesity, the metabolic syndrome, and type 2 diabetes mellitus and suggest that 1H-imidazole-4-carboxamide, 5-amino-1-[2,3-dihydroxy-4-[(phosphonooxy)methyl]cyclopentyl-[1R-(1a,2b,3b,4a)]] and aurothiomalate or similar agents that selectively inhibit hepatic aPKC may be useful treatments.

A variety of Lewis acids have been examined for the transformation of glucose and fructose into 5-hydroxymethylfurfural (5-HMF) in ionic liquids (ILs). SnCl_n, and CrCl_n are effective catalysts for the isomerization, and Lewis acids with strong acidity can facilitate the dehydration of fructose. The influence of ILs structure, including the length of alkyl side chain and halide anions, on the conversion was also studied. A distinct odd-even carbon-atom-number effect is observed in the conversion of glucose to 5-HMF and the imidazolium bromides with short alkyl side-chains can provide a higher yield of 5-HMF from fructose. In the presence of 1-ethyl-3-methylimidazolium bromide ([C₂MIM]Br) and SnCl₂, the yields of 5-HMF are 65% and 73% from glucose and fructose, resp.

And the article was included in Chinese Journal of Chemistry in 2013.COA of Formula: C11H20N2 This article mentions the following:

The coordination mode of IL-supported diols used as phosphine-free ligands for palladium catalyzed Heck reaction was investigated by tuning their compositions The difference in coordination of these IL-supported diols with metal Pd in Heck reaction was related to the changes of the cation rings, leading to the different activities of Pd catalyst in the reaction. The exptl. results indicated that the activities of Pd catalyst were affected mainly by 蟺-electron d. of the cation rings. Compared to pyridinium and piperidinium cations, imidazolium cations showed the best coordination to metal Pd. In the meantime, C-2 hydrogen and the length of alkyl side chains had impacts on the coordination as well.

Peptide agonists of the glucagon-like peptide-1 receptor (GLP-1R) have revolutionized diabetes therapy, but their use has been limited because they require injection. Herein, we describe the discovery of the orally bioavailable, small-mol., GLP-1R agonist PF-06882961 (danuglipron). A sensitized high-throughput screen was used to identify 5-fluoropyrimidine-based GLP-1R agonists that were optimized to promote endogenous GLP-1R signaling with nanomolar potency. Incorporation of a carboxylic acid moiety provided considerable GLP-1R potency gains with improved off-target pharmacol. and reduced metabolic clearance, ultimately resulting in the identification of danuglipron. Danuglipron increased insulin levels in primates but not rodents, which was explained by receptor mutagenesis studies and a cryogenic electron microscope structure that revealed a binding pocket requiring a primate-specific tryptophan 33 residue. Oral administration of danuglipron to healthy humans produced dose-proportional increases in systemic exposure (NCT03309241). This opens an opportunity for oral small-mol. therapies that target the well-validated GLP-1R for metabolic health.

Inelastic neutron scattering study on boson peaks of imidazolium-based ionic liquids was written by Kofu, Maiko;Inamura, Yasuhiro;Moriya, Yosuke;Podlesnyak, Andrey;Ehlers, Georg;Yamamuro, Osamu. And the article was included in Journal of Molecular Liquids in 2015.Reference of 79917-89-8 This article mentions the following:

Low energy excitations of 1-alkyl-3-methylimidazolium ionic liquids (ILs) have been investigated by means of neutron spectroscopy. In the spectra of inelastic scattering, a broad excitation peak referred to as a “boson peak” appeared at 1-3 meV in all of the ILs measured. The intensity of the boson peak was enhanced at the Q positions corresponding to the diffraction peaks, reflecting the in-phase vibrational nature of the boson peak. Furthermore the boson peak energy (E_BP) was insensitive to the length of the alkyl-chain but changed depending on the radius of the anion. From the correlation among E_BP, the anion radius, and the glass transition temperature T_g, we conclude that both E_BP and T_g in ILs are predominantly governed by the inter-ionic Coulomb interaction which is less influenced by the alkyl-chain length. We also found that the E_BP is proportional to the inverse square root of the mol. weight as observed in mol. glasses. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Reference of 79917-89-8).
