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

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.

Herein we report the multicomponent synthesis of the bis(indolyl)methane derivatives in a ball mill. The reaction was carried out under solvent-free conditions using only the Lewis acid-surfactant-SiO2 composite nanocatalyst (LASSC) prepared in situ. The unsymmetrical bis(indolyl) methane derivatives containing nitro or fluorine substitution with a yield of 72%-92% were obtained in a short reaction time. Within we verified that under the action of the combined catalyst of AlCl3 center dot 6H(2)O + SDS + SiO2, the method of preparing unsymmetrical bis(indolyl)methane by mechanical grinding without solvent has obvious advantages. Finally, we inspected that the catalysis system can be used eight times without a significant decrease in activity.

Fe3O4@NCs/Cu(II) as a bio-based magnetic nano-catalyst was prepared by adding CuCl2 to Fe3O4@NCs in alkaline medium. A series of indenopyrido [2,3-d] pyrimidines were synthesized by one-pot three-component reaction of 6-amino-2-(methylthio)pyrimidin-4(3H)-one, 1,3-indanedione and various aldehydes using Fe3O4@NCs/Cu(II) as an efficient and eco-friendly catalyst in ethanol at 60 degrees C. After completion of the reaction, the catalyst was separated by an external magnet and reused for the next experiment. Several advantages of this protocol are good yields, short reaction times, easy work-up and eco-friendly of the catalyst. The structure of the products were confirmed by elemental analyses, IR, H-1 NMR and C-13 NMR spectra. [GRAPHICS] .

A one-pot, Hantzsch ester-mediated Knoevenagel condensation-reduction reaction has been developed for alkylation of a wide range of substituted 2,4-quinoline diols and 2,4-pyridine diols with aldehydes. The process is operationally simple to perform, scalable, and provides highly useful C-3 alkylated quinoline and pyridine diols in yields of 58-92%. The alkylation products can be converted to 2,4-dihaloquinoline and pyridine substrates for further functionalization.

A series of novel imidazopyridine derivatives of indole has been synthesized. All the synthesized derivatives were evaluated for their antiproliferative activity against A-549, T-47D, Hep-G2 and MCF-7 human cancer cell lines. The results demonstrated that some of these derivatives exhibited moderate to excellent cytotoxic activities. Compounds 7a having a cyclohexyl ring substituted to the second amine of imidazopyridyl moiety and phenyl ring of the C-2 indole ring and 7f with a para-methylphenyl ring at the same position exhibited the highest activity against the A-594 cell line with IC50 of 11.48 mu M and 10.66 mu M, respectively. The results indicate that compounds 7a and 7f are more cytotoxic towards cancer cell lines compared with etoposide in vitro. In addition, compounds, 7d and 7j showed the most potent activity against Hep-G2, equal to etoposide as the standard drug. Also, most of the compounds were inactive against the T-47D and MCF-7 cell lines. The morphological analysis by the acridine orange/ethidium bromide double-staining test and flow cytometry analysis indicated that compounds 7a and 7f induced apoptosis in A-549 cells. Furthermore, in silico and in vitro results of the synthesized compounds showed good correlation with each other. Molecular docking results of the compounds of the 7a-k series with the cyclohexyl ring substituted to the second amine of the imidazopyridyl moiety compared with the 7l-t members with the t-butyl group at the same position confirmed the effect of the higher lipophilicity on hydrophobic interactions with the studied enzymes. Moreover, all the compounds showed higher affinity to tubulin than topoisomerase II alpha enzyme.

Developing a greener, sustainable catalyst is a very important but challenging task in organic synthesis. Herein, for the first time, we choose more economical and greener surface modified sewage sludge-derived carbonaceous materials (SW) treated by perchloric acid as a new catalyst for carbene insertion of alpha-aryl alpha-diazoacetates into O-H bonds of phenols with good yields and high functional group tolerance. Significantly, we explored the scope of natural phenols with compelling biological activity, and successfully afforded the O-H insertion and meta C-H functionalization products. Their structures have been confirmed by single-crystal X-ray crystallography. Furthermore, the bioactivities (anti-tumor and anti-inflammatory) of the majority of O-H insertion products are better than those of the natural phenols themselves. The IC50 values indicated that the remarkable compounds 7a (IC50 = 16.80 mu M) and 7c (IC50 = 16.48 mu M) had better inhibition for tumor cell A-549 than positive control DDP (IC50 = 20.62 mu M). It should be noted that these transformations may provide a new strategy to derive natural products and discover new drugs.
