Nano copper ferrite catalyst is prepared and characterized by scanning electron microscopy, energy dispersive X-ray, X-ray diffraction, vibrational sample magnetometry, and Fourier transform infrared. The catalytic activity is probed for cross-dehydrogenative coupling of aromatic aldehydes in the presence of tert-butyl hydroperoxide as the oxidant. This catalytic protocol appears as a simple, rather cheap, clean, and efficient practical strategy for the synthesis of symmetrical anhydrides, with proper efficiency (66%). The catalyst can be easily separated from the reaction mixture by an external magnet and reused several times in subsequent reactions, without any measurable loss of its efficiency. [GRAPHICS] .

beta-Glucosidase from bitter almonds was immobilized on epoxy group-functionalized beads for catalyzing salidroside synthesis in a two-step process with n-butyl–D-glucoside (BG) as the glucosyl donor. The formation of salidroside ((0.59 +/- 0.02) M) at a yield of 39.04%+/- 1.25% was accomplished in 8h by the transglucosylation of immobilized -glucosidase at pH8.0 and 50 degrees C when the ratio of BG to tyrosol was 1:2 (mol/mol). A study on the influence of different glycosyl acceptors demonstrated that the yield of the glucosylation reaction of phenylmethanol and cyclohexanol was higher than that of either phenol or cyclohexanol. This may account for the selectivity of the immobilized enzyme towards the alcoholic hydroxyl group of tyrosol in the salidroside synthesis reaction. A study on the synthesis of BG via the reverse hydrolysis of immobilized -glucosidase showed that a yield of 78.04%+/- 2.2% BG can be obtained with a product concentration of (0.23 +/- 0.015) M.

In European countries, silage-free feeding is an ancient tradition and has a particularly positive reputation among consumers. In the present study, we compared grass-based forages from the same plot conserved as hay or silage or fed fresh either on pasture or indoors, and we evaluated the differences in sensory properties of milk and uncooked pressed cheese. All herbage from the first cut of a grassland dominated by perennial ryegrass was harvested on the same day and preserved either as hay or silage. The first regrowth of the same plot was used for strip grazing or green feeding indoors. Balanced by breed, 24 Montbeliarde and 24 Holstein cows were allocated to the 4 treatments. Apart from the forages, the late-lactation cows received 3 kg/d of dry matter from concentrate. After 2 wk of dietary adaptation, the bulk milk of 3 subgroups, each with 4 cows, was collected. Part of the milk was pasteurized, and part was left raw and partly transformed to small-sized Cantal-type cheese ripened for 9 wk. Milk and cheese underwent descriptive sensory analysis by a trained sensory panel, as well as analyses of physicochemical traits. Volatile organic compounds of the cheeses were also analyzed. Raw and pasteurized milk from hay-fed cows had less intense odors of cooked milk, cream, and barnyard than milk from grazing cows, whereby the effect of pasteurization did not differ between herbage utilization methods. Cheeses obtained from cows fed fresh herbage (grazing and indoors) were clearly yellower than cheeses from silage- and hay-fed cows, which coincided with the color intensity perceived by the panelists. Moreover, cheeses from cows fed fresh herbage had more intense barnyard and dry fruit flavors, were perceived as creamier and having less lactic odor, and exhibited more fat exudation than those from cows fed conserved herbage. Only a few differences were observed in milk and cheeses from hay-fed compared with silage-fed cows, and those differences were far less pronounced than those of milk and cheeses from cows fed fresh herbage. In conclusion, the present study did not substantiate assumptions of clear sensory differences of milk and uncooked pressed cheese from hay-fed compared with silage-fed cows. For the first time, this study reports that the global flavor intensity of cheeses from indoor green-fed cows is similar to that of cheeses derived from cows fed conserved forages, whereas cheeses from grazing cows have the greatest global flavor intensity.Y

The goal of this paper is the evaluation of fast two-dimensional gas chromatography applied to bio-oil samples. Bio-oils are complex matrixes that usually are analyzed by conventional gas chromatography, involving long columns, long time of analysis due to slow heating rates, and consequently, high cost associated to time consumed. Fast gas chromatography techniques are based on the use of narrow capillary columns that allow the achievement high-speed separations for complex samples, maintaining excellent resolution. Firstly, the two-dimensional gas chromatography method was optimized varying the heating rate (10, 15 and 20 degrees C min(-1)) and achieving the optimal separation at 15 degrees C min(-1). This method allies a good separation of bio-oil constituents with shorter time analysis. The developed method and the traditional conventional two-dimensional gas chromatography method (used in previous studies) were applied in the analysis of a mixture of 30 standard compounds. Despite coelutions of short retention time peaks (compounds with very similar physical-chemical properties), the fast two-dimensional gas chromatography method showed an increase in chromatographic signal and a noise reduction. Good results were also obtained in the real bio-oil sample. Fast two-dimensional gas chromatography maintained all the chromatographic information from conventional two-dimensional gas chromatography, reducing drastically the total time of analysis.

6-Formylisoophiopogonone B (7a) and 8-formylophiopogonone B (7b), two natural products isolated from Ophiopogon japonicus, represent a subgroup of rare 6/8-formyl/methyl-homoisoflavonoid skeletons. Herein we report an efficient method for the synthesis of these formyl/methyl-homoisoflavonoids. The synthesized compounds were evaluated for their neuroprotective effects on the MPP(+)induced SH-SYSY cell injury model and showed marked activity. Exploration of the neuroprotective mechanisms of compound 7b led to an increased expression of autophagy marker LC3-II and down-regulation of autophagy substrate p62/SQSTM1. Molecular docking studies showed that 7b may prevent the inhibition of the classic PI3K-AKT-mTOR signaling pathway by interfering with the human HSP90AA1.

Background: Pyrazole derivatives have been reported to possess numerous pharmacological activities viz., anti-inflammatory, antipsychotic, etc. Our group has disclosed that pyrazole benzamides display potent antibacterial and anti-tubercular activities. Objective: Synthesis of new pyrazole acetamides which possess hydrazone group to be evaluated for antitubercular activity. Methods: The key intermediate 5-aminopyrazole was synthesized with the known procedure, which is then converted into chloroacetamide. This compound than resulted in hydrazine derivative and finally converted into aromatic hydrazones. All the compounds were screened for antitubercular activity. Result: All the synthesized compounds have been characterized by their spectral data obtained and subjected to anti-tubercular activity. Among all the twenty tested compounds, three compounds, 5a5, 5b5 and 5b7 have demonstrated MIC value of 3.12 mu g/mL against MTB H37Rv. Docking studies revealed important hydrogen bonding interactions with InhA. Conclusion: Three compounds 5a5, 5b5 and 5b7 were found to be most potent among the series of compounds. Docking studies of compounds explained the presence of hydrogen bonding and pp stacking interactions with InhA. Further synthesis of more such derivatives with optimized groups would produce compounds with more potent anti-tubercular activity.

A novel poly(ionic liquid) (PIL)-containing diblock copolymer was synthesized via a sequential living/controlled polymerization approach. First, the ring-opening polymerization of epsilon-caprolactone (CL) was carried out to obtain a monohydroxyl-terminated PCL. The terminal hydroxyl group of the PCL chain was then exploited to react with carboxyl group of 2-(dodecylthiocarbonothioylthio)-2-methylpropanoic acid to obtain a trithiocarbonate-terminated PCL. Thereafter, such trithiocarbonate-terminated PCL was used to mediate the radical polymerization of tri-n-butyl-(4-vinylbenzyl) phosphoniumbis(trifluoromethane)sulfonamide (TBP+-TFSI-) to afford PIL diblock copolymers. Notably, the PIL diblock copolymers are capable of displaying self-assembly behavior in selective solvent (e.g., ethyl acetate). In the suspensions of ethyl acetate, the self-assembly generated the spherical micelles with the aggregates of P(TBP+-TFSI-) as the cores and with PCL blocks as the coronas. Such a self-assembly behavior was further employed to obtain epoxy thermoset with nanostructures. Owing to the introduction of fluorine-containing PIL diblock copolymer, the surface dewettability of the thermosets was significantly improved owing to the enrichment of P(TBP+-TFSI-) at the surface. The introduction of PIL microdomains in epoxy resulted that the dielectric constants of the materials were significantly enhanced. More importantly, the dielectric constants were temperature-dependent and can be further enhanced while the nanostructured thermosets were heated above the glass transition temperature of PIL blocks.

An expeditious microwave assisted one-pot sequential route to synthesize pyrido fused imidazo[4,5-c]quinolines via the Pictet-Spengler cyclization strategy has been developed. In this study, substituted 2-amino pyridines are condensed with 2-bromo-2 ‘-nitroacetophenone to generate imidazo[1,2-a]pyridines with nitro group functionality at C-2 position. Reduction of nitro group to its amine congener in green media followed by the Pictet-Spengler cyclization strategy with substituted aldehydes led to the formation of new C-C and C-N bonds in a one-pot sequential manner. The cyclization proceeds through the CO(carbonyl)-C(H) cleavage of the aldehyde group via oxidative cross-coupling, transamination, cyclization and aromatization steps. Low cost reagents and a green solvent were used to facilitate the architecturally beautiful pyrido fused imidazo[4,5-c]quinoline scaffolds in high yields. The key features of this synthetic protocol are the use of microwave-assisted mild reaction conditions, one-pot sequential pathway, broad substrate scope and green media, which make it feasible for the synthesis of fused polyheterocycles. Moreover, the synthetic manipulation proceeded well with heteroaromatic and aliphatic aldehydes also in good yields.

Pressure-sensitive adhesives (PSAs) such as sticky notes and labels are a ubiquitous part of modern society. PSAs with a wide range of peel adhesion strength are designed by tailoring the bulk and surface properties of the adhesive. However, designing an adhesive with strong initial adhesion but showing an on-demand decrease in adhesion has been an enduring challenge in the design of PSAs. To address this challenge, we designed alkoxyphenacyl-based polyurethane (APPU) PSAs that show a photoactivated increase and decrease in peel strength. With increasing time of light exposure, the failure mode of our PSAs shifted from cohesive to adhesive failure, providing residue-free removal with up to 83% decrease in peel strength. The APPU-PSAs also adhere to substrates submerged underwater and show a similar photoinduced decrease in adhesion strength.
