As an alternative to volatile organic solvents, ionic liquids (ILs) are known as green solvents, and widely used in industrial applications. However, due to their high solubility and stability, ILs have tendency to persist in the water environment, thus having potential negative impacts on the aquatic ecosystem. For assessing the environmental risks of ILs, a fundamental understanding of the toxic effects and mechanisms of ILs is needed. Here we evaluated the cytotoxicity of 1-methyl-3-decylimidazolium chloride ([C(10)mim]Cl) and elucidated the main toxic mechanism of [C(10)mim]Cl in human cervical carcinoma (Hela) cells. Microstructural analysis revealed that [C(10)mim]Cl exposure caused the cell membrane breakage, swollen and vacuolated mitochondria, and spherical cytoskeletal structure. Cytotoxicity assays found that [C(10)mim]Cl exposure increased ROS production, decreased mitochondrial membrane potential, induced cell apoptosis and cell cycle arrest. These results indicated that [C10mim]Cl could induce damage to cellular membrane structure, affect the integrity of cell ultrastructure, cause the oxidative damage and ultimately lead to the inhibition of cell proliferation. Moreover, alterations of biochemical information including the increased ratios of unsaturated fatty acid and carbonyl groups to lipid, and lipid to protein, and the decreased ratios of Amide I to Amide II, and alpha-helix to beta-sheet were observed in [C(10)mim]Cl treated cells, suggesting that [C(10)mim]Cl could affect the structure of membrane lipid alkyl chain and cell membrane fluidity, promote the lipid peroxidation and alter the protein secondary structure. The findings from this work demonstrated that membrane structure is the key target, and membrane damage is involved in [C(10)mim]Cl induced cytotoxicity.

Reducing or eliminating organic solvent use in pharmaceutical manufacturing is perhaps the most effective way to reduce the environmental, health, and safety impacts of drug substance manufacturing. With this in mind, we have developed a process to manufacture an investigational 6-HT4 receptor agonist that is conducted almost entirely in water, including multiple controlled isolations. Key transformations carried out in aqueous media include a benzimidazole cyclization, amide bond formation, reductive amination, and a selective oxidation of an aliphatic alcohol. Compared to the first-generation manufacturing process using organic solvents, the aqueous process described here uses 77% less material inputs, 94% less organic solvent, and, surprisingly, 48% less water, while improving overall yield from 35% to 56%.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 5813-64-9. The above is the message from the blog manager. SDS of cas: 5813-64-9.

The food-borne trichothecene mycotoxins have been documented to cause human and animal food poisoning. Anorexia is a hallmark of the trichothecene mycotoxins-induced adverse effects. Type B trichothecenes have been previously demonstrated to elicit robust anorectic responses, and this response has been directly linked to secretion of the gut satiety hormones cholecystokinin (CCK) and glucagon-like peptide-1(7-36) amide (GLP-1). However, less is known about the anorectic effects and underlying mechanisms of the type A trichothecenes, including T-2 toxin (T-2), HT-2 toxin (HT-2), diacetoxyscirpenol (DAS), neosolaniol (NEO). The purpose of this study was to relate type A trichothecenes T-2, HT-2, DAS and NEO-induced anorectic response to changes plasma concentrations of CCK and GLP-1. Following both oral gavage and intraperitoneal (IP) administration of 1 mg/kg bw T-2, HT-2, DAS and NEO evoked robust anorectic response and secretion of CCK and GLP-1. Elevations of plasma CCK markedly corresponded to anorexia induction by T-2, HT-2, DAS and NEO. Following oral exposure, plasma CCK was peaked at 6 h, 6 h, 2 h, 2 h and lasted up to 24 h, 24 h, > 6 h, > 6 h for T-2, HT-2, DAS and NEO, respectively. IP exposed to four toxins all induced elevation of CCK with peak point and duration at 6 h and > 24 h, respectively. In contrast to CCK, GLP-1 was moderately elevated by these toxins. Following both oral and IP exposure, T-2 and HT-2 evoked plasma GLP-1 elevation with peak point and duration at 2 h and 6 h, respectively. Plasma GLP-1 was peaked at 2 h and still increased at 6 h for IP and oral administration with DAS and NEO, respectively. In conclusion, CCK plays a contributory role in anorexia induction but GLP-1 might play a lesser role in this response.

As silk is made up of proteins, their structures are easy to be changed by high temperature, high humidity, pollutants and other factors. In order to scientifically evaluate the influence of pollutant gases on silk fabrics structures, artificial simulated experiments were conducted to prepare common pollutant gas environments in museums, including nitrogen dioxide, sulfur dioxide, acetic acid and ammonia. The effects of the four kinds of pollutant gases on protein peptides, secondary structures and other aspects were investigated using Fourier transform infrared spectroscopy (FTIR). The experimental results showed that for silk fabrics aging with nitrogen dioxide for 30 h, there arose the peak of the methyl symmetric deformation vibration, near 1 382 cm(-1), which did not appear on the samples aging with other gases for 50 days. It was shown that nitrogen dioxide had the most serious damage to silk fabrics. After aging with all pollutant gases, the absorption peaks of -Gly-Ala- and -Gly-Gly-peptide chains (primary structure) at 975 and 999 cm(-1) were all reduced in varying degrees, but the effect of the alkaline gas ammonia on the peptide chains was more obvious than that of other acidic gases. The deconvolution of the amide III band (1 330 similar to 1 200 cm(-1)) and Gaussian fitting results showed that the samples aging with ammonia for 50 days had only slight changes in the amorphous region with slight content changes of a-helix, random coil and (3-sheet, and the secondary structures of silk protein did not change much. In comparison with ammonia, acid gases had a significant influence on the secondary structures of silk protein. The relative content of (3-sheet was greatly reduced with that of random coils increasing significantly, and the crystalline region was damaged seriously. Among the four gases, nitrogen dioxide has the most significant effect on secondary structures of silk fabrics. The relative content of (3-sheets decreased from 30.36% to 18.12% after 30 hours’ aging, which reduced about 40%. The nitrogen dioxide had the most serious damage to the strength of silk fabrics. With the declining of the (3-sheet, the mechanical strength of the material decreased. The ratios of infrared absorption peaks at different wavenumbers A(1) (700/1 640) and A(1) (620/1 514) were used to judge the aging modes. Oxidation reaction occurred mainly to the samples aging with nitrogen dioxide, sulfur dioxide, and ammonia. Both oxidation and hydrolysis reaction happened to the samples aging with acetic acid. With the increase of aging time, the ratio of A(1 620/1 514) of the samples aged with nitrogen dioxide increased most among the four gases and the oxidation was the most severe. It was inferred that it was related to the strong oxidizing property of nitrogen dioxide, also associated with the significant methyl symmetry vibration occurring of the silk fabric aging with nitrogen dioxide. It is suggested that the concentration of nitrogen dioxide gas should be strictly monitored and controlled in museums. This study provides a scientific basis for formulating a reasonable storage environment for silk cultural relics, and is of great significance to the protection of silk cultural relics.

Ni2B@Cu2O and Ni2B@CuCl2 are introduced as simple and efficient earth-abundant transition-metal-based nanocomposites for thegreen one-pot reductive acetylation of aromatic nitro compounds and direct N-acetylation of arylamines using a solvent-free mechanochemical grinding technique. The designed Ni2B-based nanocomposites were characterized by Fourier-transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) analysis, and scanning electron microscopy (SEM) with energy-dispersive X-ray (EDX) spectroscopy. Notable advantages of these methods include broad substrate scope, use of a solvent-free mechanochemical grinding technique, implementation of earth-abundant transition-metal-based nanocomposites as simple and practical catalysts, and short reaction time and high yield at ambient condition. The mentioned methods can also be successfully applied for thesynthesis of a broad range of other amides (especially substituted acetamides) using green chemistry protocols. Also, the recoverability and reusability of the mentioned new nanocomposites were investigated. [GRAPHICS] .

Cholesteryl-beta-D-glucoside (ChoGlc) is a mammalian glycolipid that is expressed in brain tissue. The effects of glucosylation on the ordering and lipid interactions of cholesterol (Cho) were examined in membranes composed of N-stearoyl sphingomyelin (SSM), which is abundant in the brain, and to investigate the possible molecular mechanism involved in these interactions. Differential scanning calorimetry revealed that ChoGlc was miscible with SSM in a similar extent of Cho. Solid-state H-2 NMR of deuterated SSM and fluorescent anisotropy using 1,6-diphenylhexatriene demonstrated that the glucosylation of Cho significantly reduced the effect of the sterol tetracyclic core on the ordering of SSM chains. The orientation of the sterol core was further examined by solid-state NMR analysis of deuterated and fluorinated ChoGlc analogues. ChoGlc had a smaller tilt angle between the long molecular axis (C3-C17) and the membrane normal than Cho in SSM bilayers, and the fluctuations in the tilt angle were largely unaffected by temperature-dependent mobility changes of SSM acyl chains. This orientation of the sterol core of ChoGlc leads to reduce sterol-SSM interactions. The MD simulation results suggested that the Glc moiety perturbs the SSM-sterol interactions, which reduces the umbrella effect of the phosphocholine headgroup because the hydrophilic glucose moiety resides at the same depth as an SSM amide group. These differences between ChoGlc and Cho also weaken the SSM-ChoGlc interactions. Thus, the distribution and localization of Cho and ChoGlc possibly control the stability of sphingomyelin-based domains that transiently occur at specific locations in biological membranes.

The self-assembly properties of nine low-molecular-weight gelators (LMWGs) based on bile acid alkyl amides were studied in detail. Based on the results, the number of hydroxyl groups attached to the steroidal backbone plays a major role in the gelation, although the nature of the aliphatic side chain also modulates the gelation abilities. Of the 50 gel systems studied, 35 are based on lithocholic acid and 15 on cholic acid derivatives. The deoxycholic acid derivatives did not form any gels. The gelation occurred primarily in aromatic solvents and the gels manifested typical fibrous or spherical morphologies. The C-13 cross-polarized magic angle spinning (CPMAS) NMR spectra measured on the crystalline materials and the corresponding wet organogels were analogous, suggesting that the chemical environments, that is, the intermolecular interactions found in the two materials were similar. The single-crystal X-ray structures of all nine bile-acid amide derivatives studied revealed very similar molecular conformations in the solid state and gave insights into the possible intermolecular interactions in the gel state.

Insulin resistance is an independent negative predictor of outcome after elective surgery and increases mortality among surgical patients in intensive care. The incretin hormone glucagon-like peptide-1 (GLP-1) potentiates glucose-induced insulin release from the pancreas but may also increase insulin sensitivity in skeletal muscle and directly suppress hepatic glucose release. Here, we investigated whether a penoperative infusion of GLP-1 could counteract the development of insulin resistance after surgery. Pigs were randomly assigned to three groups; surgery/control, surgery/GLP-1, and sham/GLP-1. Both surgery groups underwent major abdominal surgery. Whole-body glucose disposal (WGD) and endogenous glucose release (EGR) were assessed preoperatively and postoperatively using D-[6,6 H-2(2)]-glucose infusion in combination with hyperinsulinemic euglycemic step-clamping. In the surgery/control group, peripheral insulin sensitivity (i.e., WGD) was reduced by 44% relative to preoperative conditions, whereas the corresponding decline was only 9% for surgery/GLP-1 (P < 0.05). Hepatic insulin sensitivity (i.e., EGR) remained unchanged in the surgery/control group but was enhanced after GLP-1 infusion in both surgery and sham animals (40% and 104%, respectively, both P < 0.05). Intraoperative plasma glucose increased in surgery/control (similar to 20%) but remained unchanged in both groups receiving GLP-1 (P < 0.05). GLP-1 diminished an increase in postoperative glucagon levels but did not affect skeletal muscle glycogen or insulin signaling proteins after surgery. We show that GLP-1 improves intraoperative glycemic control, diminishes peripheral insulin resistance after surgery, and suppresses EGR. This study supports the use of GLP-1 to prevent development of postoperative insulin resistance. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 57-13-6.
