In this study, inulin was extracted from Jerusalem artichoke tuber (JAT) powder and then concentrated before spray drying. The aims of this study were to (1) determine the drying condition that provided high powder yield together with superior qualities of JAT inulin powder and (2) investigate the chem. and phys. properties of inulin powder. The inulin extracts at different concentrations of 10, 20, and 30 °Brix were spray-dried and then compared. The spray drying experiments were conducted at the inlet/outlet air temperatures of 150/90, 170/90, and 190/90 °C for the chosen concentration of inulin extract It appeared that spray drying of the 30 °Brix extract at the inlet/outlet drying air temperatures of 190/90 °C resulted in the highest value of powder recovery, bulk d., water solubility and the lowest moisture content and hygroscopicity in comparison with its counterparts. SEM micrographs showed that the powder produced by this condition was more stable and less sticky than others. The sugars, total fructo-oligosaccharides (1-kestose, nystose, and 1^F-β-fructofuranosyl nystose) and inulin-type fructans contents of powder were 12.88, 11.12, and 64.36 g/100 g of powder, resp. The moisture sorption data and models developed in this work could be used for determining the suitable condition of surrounding air for inulin powder storage. 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).

Study of the β-oxygen effect in the Barton-McCombie reaction for the total synthesis of (4R,5R)-4-hydroxy-γ-decalactone (Japanese orange fly lactone): a carbohydrate based approach was written by Desireddi, Janardana Reddi;Rao, Mora Mallikarjuna;Murahari, Kiran Kumar;Nimmareddy, Rajashekar Reddy;Mothe, Thirupathi;Lingala, Arun Kumar;Maiti, Bhimcharan;Manchal, Ravinder. 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).

Tetrahydrofuran (THF), or oxolane, is mainly used as a precursor to polymers. Being polar and having a wide liquid range, THF is a versatile solvent. 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.HPLC of Formula: 582-52-5

The gene encoding difructose anhydride III (DFA III)-forming inulin fructotransferase (IFTase) from Arthrobacter chlorophenolicus A6 was cloned and overexpressed in Escherichia.coli. The recombinant IFTase (DFA III-forming) was purified using one-step nickel affinity chromatog. Based on sodium dodecyl sulfate-polyacrylamide gel electrophoresis and gel filtration analyses, the enzyme showed a homotrimeric form composed of three identical subunits, each with an apparent mol. mass of 43 kDa. The maximum catalytic activity was shown at 65°C and pH 5.5, and the specific activity was measured as 902 U mg^-1. The enzyme showed remarkable thermostability and over half of the initial activity was retained after incubation at 80°C for 1 h. The K_m and V_max were estimated to 12.93 mM and 2.89μmol min^-1 ml^-1, resp. After complete hydrolysis of inulin for DFA III production by the purified enzyme, the produced minor products contained sucrose (GF), 1-kestose (GF₂), and nystose (GF₃). The smallest substrate was identified to be GF₃. When 50, 100, and 200 g l^-1 of inulin were hydrolyzed by the purified IFTase, the DFA III yield reached 81%, 72%, and 67%, resp.

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).

Tetrahydrofuran and dihydrofuran form the basic structural unit of many naturally occurring scaffolds like gambieric acid A and ciguatoxin, goniocin, and some biologically active molecules. THF can also be synthesized by catalytic hydrogenation of furan. This allows certain sugars to be converted to THF via acid-catalyzed digestion to furfural and decarbonylation to furan, although this method is not widely practiced. THF is thus derivable from renewable resources.Category: tetrahydrofurans

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).

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.

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.

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).

Role of root exudates on assimilation of phosphorus in young and old Arabidopsis thaliana plants was written by Pantigoso, Hugo A.;Yuan, Jun;He, Yanhui;Guo, Qinggang;Vollmer, Charlie;Vivanco, Jorge M.. And the article was included in PLoS One in 2020.Electric Literature of C18H32O16 This article mentions the following:

The role of root exudates has long been recognized for its potential to improve nutrient use efficiency in cropping systems. However, studies addressing the variability of root exudates involved in phosphorus solubilization across plant developmental stages remain scarce. Here, we grew Arabidopsis thaliana seedlings in sterile liquid culture with a low, medium, or high concentration of phosphate and measured the composition of the root exudate at seedling, vegetative, and bolting stages. The exudates changed in response to the incremental addition of phosphorus, starting from the vegetative stage. Specific metabolites decreased in relation to phosphate concentration supplementation at specific stages of development. Some of those metabolites were tested for their phosphate solubilizing activity, and 3-hydroxypropionic acid, malic acid, and nicotinic acid were able to solubilize calcium phosphate from both solid and liquid media. In summary, our data suggest that plants can release distinct compounds to deal with phosphorus deficiency needs influenced by the phosphorus nutritional status at varying developmental stages. 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: 470-69-9Electric Literature of C18H32O16).

A direct nickel-catalyzed monofluoromethylation of unactivated alkyl halides e.g., (3-bromopropyl)benzene using a low-cost industrial raw material, bromofluoromethane, by demonstrating a general and efficient reductive cross-coupling of two alkyl halides e.g., (3-bromopropyl)benzene and e.g., (2-bromo-2-fluoroethyl)benzene was described. Results with 1-bromo-1-fluoroalkane also demonstrate the viability of monofluoroalkylation, which further established the first example of reductive C(sp³)-C(sp³) cross-coupling fluoroalkylation. These transformations demonstrate high efficiency, mild conditions, and excellent functional-group compatibility, especially for a range of pharmaceuticals and biol. active compounds Mechanistic studies support a radical pathway. Kinetic studies reveal that the reaction is first-order dependent on catalyst and alkyl bromide whereas the generation of monofluoroalkyl radical is not involved in the rate-determining step. This strategy provides a general and efficient method for the synthesis of aliphatic fluorides e.g, (4-fluorobutyl)benzene.
