Programmable One-Pot Synthesis of Heparin Pentasaccharide Fondaparinux was written by Dey, Supriya;Lo, Hong-Jay;Wong, Chi-Huey. And the article was included in Organic Letters in 2020.Product Details of 582-52-5 This article mentions the following:

The clin. approved Fondaparinux (Arixtra) has been used for the treatment of deep vein thrombosis and acute pulmonary embolism since 2002 and is considered to be better than the low-mol. weight heparin in terms of anticoagulation response and duration of action. However, the synthetic methods previously developed for its manufacture are relatively complicated, thus restricting its extensive use. We report here a potentially scalable and programmable one-pot synthesis of Fondaparinux using the [1,2,2] strategy and designed thioglycosides with well-defined reactivity as building blocks. In the experiment, the researchers used many compounds, for example, (3aR,5S,6S,6aR)-5-((R)-2,2-Dimethyl-1,3-dioxolan-4-yl)-2,2-dimethyltetrahydrofuro[2,3-d][1,3]dioxol-6-ol (cas: 582-52-5Product Details of 582-52-5).

Tetrahydrofuran (THF) is a Lewis base that bonds to a variety of Lewis acids such as I2, phenols, triethylaluminum and bis(hexafluoroacetylacetonato)copper(II). Tetrahydrofuran can also be produced, or synthesised, via catalytic hydrogenation of furan. This process involves converting certain sugars into THF by digesting to furfural. An alternative to this method is the catalytic hydrogenation of furan with a nickel catalyst.Product Details of 582-52-5

Engineered thermostable β-fructosidase from Thermotoga maritima with enhanced fructooligosaccharides synthesis was written by Menendez, Carmen;Martinez, Duniesky;Perez, Enrique R.;Musacchio, Alexis;Ramirez, Ricardo;Lopez-Munguia, Agustin;Hernandez, Lazaro. And the article was included in Enzyme and Microbial Technology in 2019.Application of 470-69-9 This article mentions the following:

The thermostable β-fructosidase (BfrA) from the bacterium Thermotoga maritima converts sucrose into glucose, fructose, and low levels of short-chain fructooligosaccharides (FOS) at high substrate concentration (1.75 M) and elevated temperatures (60-70°C). In this research, FOS produced by BfrA were characterized by HPAE-PAD anal. as a mixture of 1-kestotriose, 6^G-kestotriose (neokestose), and to a major extent 6-kestotriose. In order to increase the FOS yield, three BfrA mutants (W14Y, W14Y-N16S and W14Y-W256Y), designed from sequence divergence between hydrolases and transferases, were constructed and constitutively expressed in the non-saccharolytic yeast Pichia pastoris. The secreted recombinant glycoproteins were purified and characterized. The three mutants synthesized 6-kestotriose as the major component of a FOS mixture that includes minor amounts of tetra- and pentasaccharides. In all cases, sucrose hydrolysis was the predominant reaction. All mutants reached a similar overall FOS yield, with the average value 37.6% (weight/weight) being 3-fold higher than that of the wild-type enzyme (12.6%, weight/weight). None of the mutations altered the enzyme thermophilicity and thermostability. The single mutant W14Y, with specific activity of 841 U mg^-1, represents an attractive candidate for the continuous production of FOS-containing invert syrup at pasteurization temperatures In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9Application of 470-69-9).

Synthesis of rare sugar isomers through site-selective epimerization was written by Wang, Yong;Carder, Hayden M.;Wendlandt, Alison E.. And the article was included in Nature (London, United Kingdom) in 2020.Category: tetrahydrofurans This article mentions the following:

Here we report the preparation of rare sugar isomers directly from biomass carbohydrates through site-selective epimerization reactions. Mechanistic studies establish that these reactions proceed under kinetic control, through sequential steps of hydrogen-atom abstraction and hydrogen-atom donation mediated by two distinct catalysts. This synthetic strategy provides concise and potentially extensive access to this valuable class of natural compounds In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7Category: tetrahydrofurans).

AgNPs seed priming accelerated germination speed and altered nutritional profile of Chinese cabbage was written by Zhou, Xiaoding;Jia, Xiaorong;Zhang, Zhaohui;Chen, Keyu;Wang, Lianhong;Chen, Huimin;Yang, Zong;Li, Chengdu;Zhao, Lijuan. And the article was included in Science of the Total Environment in 2022.Recommanded Product: (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol This article mentions the following:

In this study, the performance of AgNPs-priming (20, 40, and 80 mg/L) on the seed germination, yield, and nutritional quality of Chinese cabbage were evaluated. We found that AgNPs-priming at 20 and 40 mg/L for 15 h significantly accelerated seed germination speed and seedling development. Cabbage seeds primed with different concentrations of AgNPs (0, 20, 40, and 80 mg/L) were then planted in a real soil and allowed to grow for 1 mo in greenhouse. AgNPs-priming at 40 mg/L showed significantly increased cabbage yield by 44.3%. Gas chromatog.-mass spectrometry (GC-MS) combining with sparse partial least squares-discriminant anal. (sPLS-DA) reveals that AgNPs priming altered the metabolite profile of cabbage leaves in a dose-dependent manner, decreasing carbohydrates and increasing nitrogen related compounds This indicates that the metabolic stimulation during germination stage can influence the entire life cycle of cabbage. The nutritional quality of cabbage edible leaves was evaluated by liquid chromatog. with tandem mass spectrometry (LC-MS/MS) and inductively coupled plasma-mass spectrometry (ICP-MS). Results showed that AgNPs-priming at all tested concentrations significantly increased the content of essential amino acids for several folds in cabbage leaves, including alanine, aspartic acid, glutamine, glutamic acid, histidine, isoleucine, leucine, lysine, phenylalanine, proline, serine, threonine, tyrosine, and valine. Meanwhile, AgNPs-priming (40 mg/L) significantly increased iron (Fe) content by 23.8% in cabbage leaves. Ag did not bioaccumulate in edible tissues, indicating the bio-safety of AgNPs-priming. These results suggest that AgNPs-priming is a low-cost and eco-friendly approach to increase crop yield and nutritional quality.

Many Chinese herbal medicines with tonifying effects contain high levels of inulin fructooligosaccharides. These herbal medicines have high development and utilization value because of their effects against dementia, depression, and oxidative stress; on improving learning and memory ability; and on enhancing immunity. In this study, a method was developed for the separation and simultaneous quantitation of fructose, glucose, sucrose, and ten inulin fructooligosaccharides by ultra-high-performance liquid chromatog. with evaporative light scattering detection within 10 min. Separation was performed on an Amide column with gradient elution. The calibration curves for the 13 constituents showed good linearity (R² > 0.9991). The limits of detection and quantification were 10.78-33.44 and 35.94-124.81 μg/mL, resp., and the recoveries ranged from 98.90 to 103.67%. This method was successfully used to quantify the 13 constituents in the Chinese herbal medicine Morinda officinalis. The contents of the ten inulin fructooligosaccharides ranged from 56.28 to 60.71%. This method is accurate, rapid and simple and can be used for quant. anal. in the quality control of herbal medicines and functional foods.

The concentration and reconstitution processes of grape juices can result in losing compounds associated with beverage quality. In this context, three tanks containing 50,000 L of grape juice were individually concentrated up to 68 Brix using a triple vacuum concentrator. The concentrated juice was reconstituted up to the original Brix of the whole juice (18.4). Phenolic compounds, sugars and organic acids were quantified by high-performance-liquid-chromatog. “Foxy” aromatic compounds were also quantified by gas-chromatog./mass-spectrometry. The concentration and reconstitution process resulted in significant losses (Tukey test, p < 0.01) of trans-caftaric acid, decreasing from 397.08 to 159.14 mg/L, chlorogenic-acid from 34.97 to 8.44 mg/L, aromatic furaneol compound from 9.06 to 1.93 mg/L, as well as total losses for gallic-acid, caffeic-acid, p-coumaric-acid, syringic-acid, hesperidin, pelargonidin-3-glucoside and epicatechin compounds The concentration and reconstitution of grape juice preserved the antioxidant capacity and most of the quantified compounds, with the reconstituted juice having good nutritional quality.

Intestinal microbiota transplantation reveals the role of microbiota in dietary regulation of RegIIIβ and RegIIIγ expression in mouse intestine was written by Udomsopagit, Teranart;Miwa, Akiho;Seki, Manami;Shimbori, Emiko;Kadota, Yoshihiro;Tochio, Takumi;Sonoyama, Kei. And the article was included in Biochemical and Biophysical Research Communications in 2020.HPLC of Formula: 470-69-9 This article mentions the following:

RegIIIβ and RegIIIγ are antimicrobial peptides expressed in intestinal epithelial cells. Expression of these peptides is reportedly decreased by high-fat diet (HFD) and increased by indigestible oligosaccharides in mice. Clearly, these dietary regimens change the structure of intestinal microbiota. We employed an intestinal microbiota transplantation (IMT) to test whether diet-induced changes in the expression of these peptides are mediated by gut microbiota. C57BL/6J mice were fed either a normal-fat diet (NFD), a HFD, or a NFD supplemented with or without 1-kestose (KES), an indigestible oligosaccharide. Ileal RegIIIβ and RegIIIγ mRNA levels were lower in mice receiving IMT from HFD-fed mice than in those receiving NFD-fed mice and higher in mice receiving IMT from KES-supplemented mice than in those receiving the mice without KES supplementation. Western blot anal. showed that serum RegIIIβ levels changed in parallel with the ileal mRNA levels. We propose that HFD- and KES-induced changes in the ileal RegIIIβ and RegIIIγ expression and in the circulating RegIIIβ levels are mediated, at least in part, by intestinal microbiota. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9HPLC of Formula: 470-69-9).

Enzymatic Process Yielding a Diversity of Inulin-Type Microbial Fructooligosaccharides was written by Vallejo-Garcia, Luz Cristina;Rodriguez-Alegria, Maria Elena;Lopez Munguia, Agustin. And the article was included in Journal of Agricultural and Food Chemistry in 2019.Formula: C18H32O16 This article mentions the following:

The specificity of fructooligosaccharides as prebiotics depends on their size and structure, which in turn depend on their origin or the synthesis procedure. In this work we describe the application of an inulosucrase (IslA) from Leuconostoc citreum CW28 to produce high mol. weight inulin from sucrose alongside a com. endoinulinase (Novozym 960) produced by Aspergillus niger for a simultaneous or sequential reaction to synthesize fructooligosaccharides (FOS). The simultaneous reaction resulted in a higher substrate conversion and a wide diversity of FOS when compared to the sequential reaction. A shotgun MS anal. of the com. endoinulinase preparation surprisingly revealed an addnl. enzymic activity: a fructosyltransferase, responsible for the synthesis of FOS from sucrose. Consequentially, the range of FOS obtained in reactions combining inulosucrase from Ln. citreum with the fructosyltransferase and endoinulinase from A. niger with sucrose as substrate may be extended and regulated. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9Formula: C18H32O16).
