Synthetic Route of 108-82-7, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 108-82-7, name is 2,6-Dimethylheptan-4-ol. A new synthetic method of this compound is introduced below.

Then, using 1-methyl-AZADO synthesized, the activities thereof as an oxidation catalyst were estimated in the same manner using various secondary alcohols specified in Tables 2 and 3. As for the reaction conditions, the catalyst amount was 0.01 eq. in CH2Cl2, and KBr (0.1 eq.), n-Bu4NBr (0.05 eq.) and NaOCl (1.4 eq.) were further added, and the reaction was carried out under ice cooling. The reaction time was 20 minutes. After completion of the reaction, the percent yield of each product was determined. The percent yield was calculated by the formula: (actual yield, i.e., the amount of product)/(theoretical yield, i.e., calculated from the amount of consumed starting material) x 100 (%). For comparative examples, runs were carried out under the same reaction conditions using TEMPO, and each comparative yield was calculated. The results thus obtained are shown in Tables 2 and 3. Table 2 [Show Image] Test No. Alcohol species Yield (%) Catalyst Me-AZADO (Invention) TEMPO (Compar. Ex.) 2-1[Show Image] 84 83 2-2[Show Image] 91 5 2-3[Show Image] 99 16 2-4[Show Image] 93 15 2-5[Show Image] 100 8 2-6[Show Image] 100 12Table 3 Test No. Alcohol species Yield (%) Catalyst Me-AZADO (Invention) TEMPO (Compar.

On the other hand, in the case of secondary alcohols having a sterically bulky, complicated structure, it was found that the use of 1-methyl-AZADO of the invention resulted in rapid oxidation, giving target products in high yields, whereas the use of TEMPO for comparison gave target products only in low yields. In view of such results, it is evident that 1-methyl-AZADO is a catalyst useful as an oxidation catalyst not only for primary alcohols but also secondary alcohols.

Computational design of highly stable and soluble alcohol dehydrogenase for NADPH regeneration

Nicotinamide adenine dinucleotide phosphate (NADPH), as a well-known cofactor, is widely used in the most of enzymatic redox reactions, playing an important role in industrial catalysis. However, the absence of a comparable method for efficient NADP(+) to NADPH cofactor regeneration radically impairs efficient green chemical synthesis. Alcohol dehydrogenase (ADH) enzymes, allowing the in situ regeneration of the redox cofactor NADPH with high specific activity and easy by-product separation process, are provided with great industrial application potential and research attention. Accordingly, herein a NADP(+)-specific ADH from Clostridium beijerinckii was selected to be engineered for cofactor recycle, using an automated algorithm named Protein Repair One-stop Shop (PROSS). The mutant CbADH-6M (S24P/G182A/G196A/H222D/S250E/S254R) exhibited a favorable soluble and highly active expression with an activity of 46.3 U/mL, which was 16 times higher than the wild type (2.9 U/mL), and a more stable protein conformation with an enhanced thermal stability: Delta T-1/2(60min) = + 3.6 degrees C (temperature of 50% inactivation after incubation for 60 min). Furthermore, the activity of CbADH-6M was up-graded to 2401.8 U/mL by high cell density fermentation strategy using recombinant Escherichia coli, demonstrating its industrial potential. Finally, the superb efficiency for NADPH regeneration of the mutant enzyme was testified in the synthesis of some fine chiral aromatic alcohols coupling with another ADH from Lactobacillus kefir (LkADH).

Application of 108-82-7, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 108-82-7.

Factors associated with the progression of gastric intestinal metaplasia: a multicenter, prospective cohort study

Background and study aims Gastric cancer (GC) is usually preceded by premalignant gastric lesions (GPLs) such as gastric intestinal metaplasia (GIM). Information on risk factors associated with neoplastic progression of GIM are scarce. This study aimed to identify predictors for progression of GIM in areas with low GC incidence. Patients and methods The Progression and Regression of Precancerous Gastric Lesions (PROREGAL) study includes patients with GPL. Patients underwent at least two upper endoscopies with random biopsy sampling. Progression of GIM means an increase in severity according to OLGIM (operative link on gastric intestinal metaplasia) during follow-up (FU). Family history and lifestyle factors were determined through questionnaires. Serum Helicobacter pylori infection, pepsinogens (PG), gastrin-17 and GC-associated single nucleotide polymorphisms (SNPs) were determined. Cox regression was performed for risk analysis and a chi-squared test for analysis of single nucleotide polymorphisms. Results Three hundred and eight patients (median age at inclusion 61 years, interquartile range (IQR: 17; male 48.4%; median FU 48 months, IQR: 24) were included. During FU, 116 patients (37.7%) showed progression of IM and six patients (1.9%) developed high-grade dysplasia or GC. The minor allele (C) on TLR4 (rs11536889) was inversely associated with progression of GIM (OR 0.6; 95%CI 0.4-1.0). Family history (HR 1.5; 95%CI 0.9-2.4) and smoking (HR 1.6; 95%CI 0.9-2.7) showed trends towards progression of GIM. Alcohol use, body mass index, history of H. pyloriinfection, and serological markers were not associated with progression. Conclusions Family history and smoking appear to be related to an increased risk of GIM progression in low GC incidence countries. TLR4(rs11536889) showed a significant inverse association, suggesting that genetic information may play a role in GIM progression.

Effect of Saccharomyces cerevisiae and Schizosaccharomyces pombe strains on chemical composition and sensory quality of ciders made from Finnish apple cultivars

Composition of volatile compounds and concentrations of sugars and organic acids were studied in apple ciders produced with Saccharomyces cerevisiae and Schizosaccharomyces pombe yeasts using eleven different Finnish apple cultivars. Moreover, sensory quality of selected ciders was studied using check-all-that-apply test with untrained panelists. Seventy-seven volatile compounds were detected in the samples using HS-SPME-GC-MS. In general, the ciders had higher concentrations of higher alcohols, aldehydes, and acetals whereas the juices contained higher contents of C6-alcohols. Simultaneously, fermentation using S. pombe resulted in lower concentrations of malic acid, ethyl pentanoate, ethyl hexanoate, and volatile acids and higher concentrations of residual sugars compared to S. cerevisiae. Ciders made using S. cerevisiae were characterized as ‘alcoholic’ and `yeasty’ while S. pombe ciders were more frequently described as ‘sweet’, ‘honey-like’, and less rated as sour. Besides the strong effect by the yeasts, apple cultivars had significant effects on the compositional and sensorial properties of apple ciders.

Experimental study of temperature profile and gas-liquid heat transfer in flame spread over jet fuel under longitudinal air flow

The rectangular pools with the same length of 100 cm but different widths of 4 and 20 cm are used to conduct experiments of flame spread over jet fuel of RP-3. The direction of longitudinal air flow is same and opposite to direction of flame spread respectively. Six air flow velocities 0.45, 0.88, 1.3, 1.73, 2.15 and 2.57 m/s are employed. The spatial temperature distributions and convective heat dissipation at pool bottom are examined using thermocouples. The heat loss is negligible for 10 mm-thick fuel layer, but it is evident for 3 mm-thick fuel layer. The integral method is proposed to calculate the flame radiation imposed to subsurface flow region. The gas-liquid heat transfer model including liquid-phase convection, flame radiation and convective heat dissipation is established for calculating energy balance involving flame spread over RP-3. The calculated heat fluxes follow well with experimental measurements, regardless of direction and magnitude of air flow. The current findings possess potential application and practical guidelines for fire prevention of liquid fires under longitudinal air flows. In order to restrict flame spread, it is a feasible method to cut off liquid convection or shield flame radiation.

Canna x generalis LH Bailey rhizome extract ameliorates dextran sulfate sodium-induced colitis via modulating intestinal mucosal dysfunction, oxidative stress, inflammation, and TLR4/ NF-kappa B and NLRP3 inflammasome pathways

Ethnopharmacological relevance: Genus Canna is used in folk medicine as demulcent, diaphoretic, antipyretic, mild laxative and in gastrointestinal upsets therapy. Canna x generalis (CG) L.H. Bailey is traditionally used as anti-inflammatory, analgesic and antipyretic. Besides, CG is used in Ayurvedic medicines’ preparations and in the treatment of boils, wounds, and abscess. Nevertheless, its anti-inflammatory effects against ulcerative colitis (UC) are not yet investigated. Aim: This study aimed to investigate the phytoconstituents of CG rhizome ethanol extract (CGE). Additionally, we aimed to comparatively evaluate its therapeutic effects and underlying mechanisms against the reference drug sulphasalazine (SAS) in dextran sodium sulfate (DSS)-induced UC in mice. Material and methods: Metabolic profiling of CG rhizomes was performed via UHPLC/qTOF-HRMS; the total phenolic, flavonoid and steroid contents were determined, and the main phytoconstituents were isolated and identified. Next, DSS-induced (4%) acute UC was established in C57BL/6 mice. DSS-induced mice were administered either CGE (100 and 200 mg/kg) or SAS (200 mg/kg) for 7 days. Body weight, colon length, disease activity index (DAI) and histopathological alterations in colon tissues were examined. Colon levels of oxidative stress (GSH, MDA, SOD and catalase) and pro-inflammatory [Myeloperoxidase (MPO), nitric oxide (NO), IL-1 beta, IL-12, TNF-alpha, and INF-gamma] markers were colourimetrically determined. Serum levels of lipopolysaccharide (LPS) and relative mRNA expressions of occludin, TLR4 and ASC (Apoptosis-Associated Speck-Like Protein Containing CARD) using RT-PCR were measured. Protein levels of NLRP3 inflammasome and cleaved caspase-1 were determined by Western blot. Furthermore, immunohistochemical examinations of caspase-3, NF-kappa B and claudin-1 were performed. Results: Major identified constituents of CGE were flavonoids, phenolic acids, phytosterols, beside five isolated phytoconstituents (beta-sitosterol, triacontanol fatty alcohol, beta-sitosterol-3-O-beta-glucoside, rosmarinic acid, 6-O-pcoumaroyl-beta-D-fructofuranosyl alpha-D-glucopyranoside). The percentage of the phenolic, flavonoid and steroid contents in CGE were 20.55, 6.74 and 98.09 mu g of gallic acid, quercetin and beta-sitosterol equivalents/mg extract, respectively. In DSS-induced mice, CGE treatment ameliorated DAI, body weight loss and colon shortening. CGE attenuated the DSS-induced colonic histopathological alternations, inflammatory cell infiltration and histological scores. CGE elevated GSH, SOD and catalase levels, and suppressed MDA, pro-inflammatory mediators (MPO and NO) as well as cytokines levels in colonic tissues. Moreover, CGE downregulated LPS/TLR4 signaling, caspase-3 and NF-kappa B expressions. CGE treatment inhibited NLRP3 signaling pathway as indicated by the suppression of the protein expression of NLRP3 and cleaved caspase-1, and the ASC mRNA expression in colonic tissues. Addi-tionally, CGE restored tight junction proteins’ (occludin and claudin-1) expressions. Conclusion: Our findings provided evidence for the therapeutic potential of CGE against UC. CGE restored in-testinal mucosal barrier’s integrity, mitigated oxidative stress, inflammatory cascade, as well as NF-kappa B/TLR4 and NLRP3 pathways activation in colonic tissues. Notably, CGE in a dose of 200 mg/kg was more effective in ameliorating DSS-induced UC as compared to SAS at the same dose.

Fabrication and electrochemical property of La0.8Sr0.2MnO3 and (ZrO2)(0.92)(Y2O3)(0.08) interface for trace alcohols sensor

A mixed potential type alcohols gas sensor based on an yttrium stabilized zirconia (YSZ) electrolyte and an La0.8Sr0.2MnO3 (LSM) sensing electrode was fabricated. The influences of YSZ-LSM interface on sensing performance were studied by multiple methods including X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), thermogravimetric analysis and differential scanning calorimetry (TG-DSC) and electrochemical impendence spectroscopy (EIS). The sensor with 1150 degrees C-sintered interface showed an ultralow detection limit of 50 ppb alcohols (methanol and ethanol) at 500 degrees C in air. The response voltage was independent of water, CO, CO2 and NOx. The sensor exhibited a reasonable selectivity towards alcohols under the existence of several kinds of volatile organic compounds. Meanwhile, the sensor showed a good repeatability and a suitable long-term stability. Based on the polarization curves and EIS results, a mixed potential mechanism was proposed. These results demonstrate the promising potential of using the LSM-based sensor for human exhale test.

Gelatinization, pasting, and rheological properties of pea starch in alcohol solution

In this study, we aimed to examine the effects of different low concentrations of alcohol solution (5%-20%) on the gelatinization and pasting properties of pea starch. A rapid visco analyzer revealed that when the starch concentration was fixed, the viscosity of the starch paste decreased with increasing alcohol concentration. In addition, the texture analyzer results showed that compared to the hydrogel formed in water, the hardness of the gel formed by 15% starch in 10% alcohol increased approximately 2-fold (1696.4 g versus 928.1 g). Furthermore, the rheological results showed that the tan delta value of the gel formed under this condition was second only to that of 20% starch in water, which indicated the gel had a strong network structure. X-ray diffraction analysis showed an increased relative crystallinity of 15% starch gels formed in 10% alcohol (13.2%) compared to the hydrogel formed in water (12.2%). Our study will expand the knowledge of the gelatinization properties of starch in low concentrations of alcohol.

Electrochemical activation to enhance the volumetric performance of carbon nanotube electrodes

In recent years, the floating catalyst chemical vapor deposition (FCCVD) method has established itself as one of the most commercially viable methods to produce carbon nanotubes (CNTs). However, at the final stage of the FCCVD process, densification of the web of CNTs to form a sheet causes a significant loss in the active surface area of the CNTs. This loss of surface area reduces the density of active materials that can be infiltrated into the CNT sheet. Reducing the amount of active material in the sheet reduces the charge storage capacity and causes low volumetric performance for CNT sheet in energy storage applications. Here, we are reporting the use of an electrochemical activation technique to chemically functionalize the CNT surface and recover the lost surface area. Chemical functionalization separates the CNTs and thereby increases the density of active materials that can be integrated into the CNT sheet. In order to avoid deterioration of the CNT structure from excessive electrochemical activation, we have optimized the procedure by comparing the performance of four samples of CNT sheets prepared using different numbers of cycles of electrochemical activation (5, 10, 20, 40 cycles). The performance of the sheet was analyzed using specific capacitance measurement, electrochemical impedance spectroscopy (EIS) analysis, and UV-vis absorption spectroscopy. In addition, the Randle-Sevcik plot was used to select the CNTs with the largest activated surface area and electrochemical specific capacitance (150F/g). Further analysis such as x-ray photoelectron spectroscopy (XPS) was also carried out to unveil a 5% increase of the various oxygen-containing functional groups at the surface of the activated CNTs. Polyaniline (PANI) was then deposited on the surface of the electrochemically altered CNTs via an oxidation polymerization process to create a CNT-PANI composite material. A fully fabricated device with CNT-PANI electrodes and Polyvinylidene fluoride – 1-Ethyl-3-methylimidazolium tetrafluoroborate (PVDF-EMIMBF4) electrolyte showed a significant specific capacitance improvement over a device with Poly(vinyl alcohol) -Sulfuric acid (PVA-H2SO4) electrolyte. The PVDF-EMIMBF4 capacitor device had a volumetric energy density of 833.3 mu M/h/cm(3) at a current density of 0.5 mA/cm(2). The capacitor has good mechanical flexibility and high capacitance retention (75% after 5000 cycles), which show the advantages of the electrochemical activation method.
