And the article was included in Polymer Bulletin (Heidelberg, Germany) in 2022.Reference of 582-52-5 This article mentions the following:

Carbohydrates are safe materials with the potential of application in various areas, hence, in recent years, a growing interest has been attracted to the synthesis of the new systems containing carbohydrates. By considering this and based on the carbohydrates merits, in this work, the new two different random glyco-copolymers were prepared through the polymerization of the α-D-glucofuranose- and α-D-mannofuranose-based monomers. A facile free-radical polymerization technique was utilized for glyco-copolymers synthesis in the presence of benzoyl peroxide (BPO) as an initiator. Fourier transform IR (FT-IR) technique was used for investigating the achievements in the synthesis of copolymers. In the proton NMR (¹H NMR) spectroscopy anal., the absence of any peaks in the rigon related to vinylic protons confirmed the successful synthesizing of glyco-copolymers. As well as, enhancing the intensity of the peaks in the 0.60-2.39 ppm which is related to the formed aliphatic protons as a result of vinylic glycomonomers copolymerization is the strong witness for success in copolymerization In this way and by considering the special structure of the prepared glyco-copolymers and based on the review of the published literature, it is expected that the prepared new glyco-copolymers be a good candidate for biomedicinal applications. 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: 582-52-5Reference of 582-52-5).

(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: 582-52-5) belongs to tetrahydrofuran derivatives. THF (Tetrahydrofuran) is water-miscible and has a low viscosity making it a highly versatile solvent used in a variety of industries. Commercial tetrahydrofuran contains substantial water that must be removed for sensitive operations, e.g. those involving organometallic compounds. Although tetrahydrofuran is traditionally dried by distillation from an aggressive desiccant, molecular sieves are superior.Reference of 582-52-5

Various superacid SO₄^2-/ZrO₂-Al₂O₃ catalysts were prepared by a coprecipitation, and modified by aging at low temperature and addition of the rare earth oxide, such as La₂O₃. A optimum at. ratio of Zr/Al was found to be 0.5, which was confirmed by the catalytic activity of samples for n-butane isomerization. IR measurements demonstrated that the intensity of the peak at 1393 cm^-1 for the samples aged at low temperature and containing the rare earth oxide was more higher than that for the samples at room temperature For the sample containing the RE oxide and aged at low temperature, XRD observed a metastable tetragonal phase of ZrO₂ crystal which is responsible for the higher catalysis activity as we believe. The observation of catalytic activity for esterification of sucrose further evidenced the conclusion mentioned above. 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: 126-14-7Application In Synthesis of (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).

And the article was included in Fitoterapia in 2020.Product Details of 126-14-7 This article mentions the following:

Although the bioactive compounds in goji have been thoroughly identified and quantified, little information is available on the bitter compounds in the berries, and no systematic works on the substances responsible for their bitterness have been performed. Herein, the substances contributing to the bitterness of berries were isolated and purified from bitter-tasting goji by the combined use of column chromatog. and high-pressure liquid chromatog. (HPLC). The bitterness of the isolated compounds was evaluated using a biosensor with immobilized rat taste-bud tissues. The structures were elucidated via comprehensive mass spectrometry (MS) and NMR (NMR) analyses. Seven spermine or spermidine alkaloids were identified, including four new compounds (lyciamarspermidines A and B and lyciamarspermines A and B). The intensities of the bitterness levels of the isolated compounds differed with the number of glucose substituents. These isolated compounds all contribute to the bitterness of goji. The results of this study provide opportunities for the further investigation of the bitterness of goji.

A γ-glutamylcysteine ligase AcGCL alleviates cadmium-inhibited fructooligosaccharides metabolism by modulating glutathione level in Allium cepa L. was written by Luo, Wei;Long, Yuming;Feng, Zili;Li, Rui;Huang, Xiaojia;Zhong, Jiaxin;Liu, Dongyun;Zhao, Hongbo. And the article was included in Journal of Hazardous Materials in 2021.Formula: C18H32O16 This article mentions the following:

Fructooligosaccharides (FOS) are important carbohydrates in plants. Cadmium (Cd) toxicity limits growth and development in several plant species. Whether FOS metabolism is affected by Cd and the mol. mechanisms of tolerance of the effects of Cd toxicity in plants remain enigmatic. In the present study, FOS metabolism was analyzed under Cd stress in onion (Allium cepa L.). Results showed that Cd stress can inhibit FOS accumulation in onion, followed by the upregulation of a putative onion γ-glutamylcysteine ligase gene AcGCL. Heterologous expression of the AcGCL protein in Escherichia coli revealed that this recombinant enzyme has GCL activity. Furthermore, overexpressing AcGCL significantly increased glutathione (GSH) accumulation in young onion roots under Cd treatment, accompanied by increased phytochelatin (PC) amount, and increased transcript expression of GSH synthetase (GS), and phytochelatin synthase (PCS) genes. Notably, compared with control, overexpressing AcGCL ameliorated Cd phytotoxicity on onion FOS metabolism, which correlated with increased FOS synthesis. Taken together, these results suggest that the function of AcGCL as a γ-glutamylcysteine ligase can alleviate Cd inhibited FOS metabolism by modulating GSH levels in onion. 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).

Thousands of environmental chems. are subject to regulatory review for their potential to be endocrine disruptors (ED). In vitro high-throughput screening (HTS) assays have emerged as a potential tool for prioritizing chems. for ED-related whole-animal tests. In this study, 1814 chems. including pesticide active and inert ingredients, industrial chems., food additives, and pharmaceuticals were evaluated in a panel of 13 in vitro HTS assays. The panel of in vitro assays interrogated multiple end points related to estrogen receptor (ER) signaling, namely binding, agonist, antagonist, and cell growth responses. The results from the in vitro assays were used to create an ER Interaction Score. For 36 reference chems., an ER Interaction Score >0 showed 100% sensitivity and 87.5% specificity for classifying potential ER activity. The magnitude of the ER Interaction Score was significantly related to the potency classification of the reference chems. ERα/ERβ selectivity was also evaluated, but relatively few chems. showed significant selectivity for a specific isoform. When applied to a broader set of chems. with in vivo uterotrophic data, the ER Interaction Scores showed 91% sensitivity and 65% specificity. Overall, this study provides a novel method for combining in vitro concentration response data from multiple assays and, when applied to a large set of ER data, accurately predicted estrogenic responses and demonstrated its utility for chem. prioritization. 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).

And the article was included in RSC Advances in 2022.HPLC of Formula: 582-52-5 This article mentions the following:

Efficient and facile synthesis of Japanese orange fly lactone I was achieved from a com. available D-glucose by investigating Barton-McCombie reaction with furanose anomeric isomers (12α, β) with an overall yield of 12.6%. During course of this synthesis, β-oxygen effect was discovered in deoxygenation step at C-3 position using Barton-McCombie reaction, where substrate allows effect to operate in one of isomers but not in other. Under same reaction conditions, xanthate derived from β-furanose isomer afforded a high yield of deoxygenated product, whereas α-isomer produced a very low yield. The key transformations used were Wittig olefination, TEMPO mediated oxidation, and Barton-McCombie deoxygenation, resulting in a concise total synthesis of Japanese orange fly lactone I. 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: 582-52-5HPLC of Formula: 582-52-5).

Superbase-Catalyzed Stereo- and Regioselective Glycosylation with 2-Nitroglycals: Facile Access to 2-Amino-2-deoxy-O-glycosides was written by Pal, Kumar Bhaskar;Guo, Aoxin;Das, Mrinmoy;Bati, Gabor;Liu, Xue-Wei. And the article was included in ACS Catalysis in 2020.Computed Properties of C12H20O6 This article mentions the following:

An efficient super-base-catalyzed stereo- and regioselective glycosylation of 2-nitroglycals with high functional group compatibility is reported. The ion pair generated from alc. and a catalytic amount of P₄-t-Bu was vital for the successful implementation of this stereoselective glycosylation under mild conditions, producing moderate to good yields. Under reported reaction conditions, 2-nitrogalactals produce α-stereoisomers exclusively, while 2-nitroglucal yielded more β-products. The notable difference between the outcomes was investigated by the d. functional theory (DFT) study. In addition, we have synthesized the key intermediate of a mucin-type core-6 glycoconjugate, thus illustrating the synthetic potency of this method. 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: 582-52-5Computed Properties of C12H20O6).

Solid acid catalysis, and the advantages often associated with their use, have been proved equally efficient for the synthesis of tetrahydrofurans or furans. It is more basic than diethyl ether and forms stronger complexes with Li+, Mg2+, and boranes. It is a popular solvent for hydroboration reactions and for organometallic compounds such as organolithium and Grignard reagents.Computed Properties of C12H20O6
