Microbial dynamics and metabolite changes in Chinese Rice Wine fermentation from sorghum with different tannin content

Chinese rice wine (CRW) is the oldest kind of wine in China and is mainly fermented by wheat Qu and yeast with rice, millet, etc. This gives CRW a unique quality, but the flavor components are complex. Its formation is related to microorganisms, but the link between CRW and microorganisms is poorly understood. Here, we used two kinds of sorghum (JZ22 and JB3, of which JZ22 has a higher tannin content) as the raw materials to brew and determined the structural and functional dynamics of the microbiota by metagenomics and flavor analyses. We detected 106 (JZ22) and 109 (JB3) volatile flavor compounds and 8 organic acids. By correlation analysis, we established 687 (JZ22) and 496 (JB3) correlations between the major flavor compounds and microbes. In JZ22, Blautia, Collinsella, Bifidobacterium, Faecalibacterium and Prevotella had the most correlations with flavor production. In JB3, the top 5 genera were Stenotrophomonas, Bdellovibrio, Solibacillus, Sulfuritalea and Achromobacter. In addition, more esters were detected, and more microorganisms correlated with ester generation in JZ22. This study provides a new idea for the micro ecological diversity of CRW fermented with sorghum. This is of significance for improving the quality and broadening the CRW varieties.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 105-21-5, and how the biochemistry of the body works.Related Products of 105-21-5

Multifunctional Cascade Catalysis of Itaconic Acid Hydrodeoxygenation to 3-Methyl-tetrahydrofuran

Hybrid production of isoprene from biomass-derived sugar as a feedstock for renewable rubber is a three-part process comprising glucose fermentation to itaconic acid, liquid-phase hydrodeoxygenation to 3-methyl-tetrahydrofuran, followed by vapor-phase dehydra-decyclization to isoprene. Here, we investigate a multifunctional catalyst design for itaconic acid hydrodeoxygenation to 3-methyl-tetrahydrofuran. The production of 3-methyl-tetrahydrofuran from itaconic acid is a multistep process involving hydrogenation, acid-catalyzed dehydration, and hydrodeoxygenation of multiple organic functionalities. A detailed kinetic analysis of this multistep reaction network over a Pd/C catalyst revealed a kinetic bottleneck in the reduction of methyl-gamma-butyrolactone to 1,4-methylbutanediol, which was accelerated through the use of Re as an oxophillic promoter. Varying ratios of Pd:Re indicated a maximum overall rate of lactone ring opening with a 3.5:1.0 Pd:Re ratio, likely due to the combined capability of Pd to hydrogenate double bonds and Re to open the lactone ring. Applying this insight, the overall rate of itaconic acid hydrodeoxygenation to 3-methyl-tetrahydrofuran increased by more than an order of magnitude.

Synthesis and biological evaluation of 1-(2,4,5-trisubstituted phenyl)-3-(5-cyanopyrazin-2-yl)ureas as potent Chk1 kinase inhibitors

Based on the X-ray crystallography of our lead compound 1-(5-chloro-2,4-dimethoxyphenyl)-3-(5-cyanopyrazin-2-yl)urea in the checkpoint kinase 1 (Chk1) enzyme, we modified R4, and to a lesser extent, R2, and R5 of the phenyl ring, and made a variety of N-aryl-N?-pyrazinylurea Chk1 inhibitors. Enzymatic activity less than 20 nM was observed in 15 of 41 compounds. Compound 8i provided the best overall results in the cellular assays as it abrogated doxorubicin-induced cell cycle arrest (IC50 = 1.7 muM) and enhanced doxorubicin cytotoxicity (IC50 = 0.44 muM) while displaying no single agent activity.

Recent Advances in the Synthesis of Cyclobutanes by Olefin [2 +2] Photocycloaddition Reactions

The [2 + 2] photocycloaddition is undisputedly the most important and most frequently used photochemical reaction. In this review, it is attempted to cover all recent aspects of [2 + 2] photocycloaddition chemistry with an emphasis on synthetically relevant, regio-, and stereoselective reactions. The review aims to comprehensively discuss relevant work, which was done in the field in the last 20 years (i.e., from 1995 to 2015). Organization of the data follows a subdivision according to mechanism and substrate classes. Cu(I) and PET (photoinduced electron transfer) catalysis are treated separately in sections 2 and 4, whereas the vast majority of photocycloaddition reactions which occur by direct excitation or sensitization are divided within section 3 into individual subsections according to the photochemically excited olefin.

Monomeric metal aqua complexes in the interlayer space of montmorillonites as strong Lewis acid catalysts for heterogeneous carbon-carbon bond-forming reactions

Montmorillonite-enwrapped copper and scandium catalysts (Cu2– and Sc3+-monts) were easily prepared by treating Na–mont with the aqueous solution of the copper nitrate and scandium triflate, respectively. The resulting Cu2+- and Sc3+-monts showed outstanding catalytic activities for a variety of carbon-carbon bond-forming reactions, such as the Michael reaction, the Sakurai-Hosomi allylation, and the Diels-Alder reaction, under solvent-free or aqueous conditions. The remarkable activity of the mont catalysts is attributable to the negatively charged silicate layers that are capable of stabilizing metal cations. Furthermore, these catalysts were reusable without any appreciable loss in activity and selectivity. The Cu2+-mont-catalyzed Michael reaction proceeds via a ternary complex in which both the 1,3-dicarbonyl compound and the enone are coordinated to a Lewis acid Cu2+ center.
