THF (Tetrahydrofuran) is water-miscible and has a low viscosity making it a highly versatile solvent used in a variety of industries. 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.Application of 582-52-5

Apoplastic maize fructan exohydrolase Zm-6-FEH displays substrate specificity for levan and is induced by exposure to levan-producing bacteria was written by Huang, Xiaojia;Luo, Wei;Wu, Silin;Long, Yuming;Li, Rui;Zheng, Fenghua;Greiner, Steffen;Rausch, Thomas;Zhao, Hongbo. And the article was included in International Journal of Biological Macromolecules in 2020.Name: (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:

Fructan exohydrolases (FEHs) are structurally related to cell wall invertases. While the latter are ubiquitous in higher plants, the role of FEHs in non-fructan species has remained enigmatic. To explore possible roles of FEHs in maize, a full length putative Zm-6-FEH-encoding cDNA was cloned displaying high sequence similarity with cell wall invertases. For functional characterization, Zm-6-FEH protein was expressed in Picha pastoris and in Nicotiana benthamiana leaves. Enzyme activity of recombinant Zm-6-FEH protein showed a strong preference for levan as substrate. Expression profiling in maize seedlings revealed higher transcript amounts in the more mature leaf parts as compared to the growth zone at the base of the leaf, in good correlation with FEH enzyme activities. Subcellular localization anal. indicated Zm-6-FEH location in the apoplast. Noteworthy, incubation of leaf disks with levan and co-incubation with high levan-producing bacteria selectively up-regulated transcript levels of Zm-6-FEH, accompanied by an increase of 6-FEH enzyme activity. In summary, the results indicate that Zm-6-FEH, a novel fructan exohydrolase of a non-fructan species, may have a role in plant defense against levan-producing bacteria.

Combining Mass Spectrometry and NMR Improves Metabolite Detection and Annotation was written by Bhinderwala, Fatema;Wase, Nishikant;DiRusso, Concetta;Powers, Robert. And the article was included in Journal of Proteome Research in 2018.Recommanded Product: 470-69-9 This article mentions the following:

Despite inherent complementarity, NMR spectroscopy (NMR) and mass spectrometry (MS) are routinely sep. employed to characterize metabolomics samples. More troubling is the erroneous view that metabolomics is better served by exclusively using MS. Instead, the authors demonstrate the importance of combining NMR and MS for metabolomics by using small chem. compound treatments of Chlamydomonas reinhardtii as an illustrative example. A total of 102 metabolites were detected (82 by gas chromatog.-MS, 20 by NMR, and 22 by both techniques). Out of these, 47 metabolites of interest were identified: 14 metabolites were uniquely identified by NMR, and 16 metabolites were uniquely identified by GC-MS. A total of 17 metabolites were identified by both NMR and GC-MS. In general, metabolites identified by both techniques exhibited similar changes upon compound treatment. In effect, NMR identified key metabolites that were missed by MS and enhanced the overall coverage of the oxidative pentose phosphate pathway, Calvin cycle, tricarboxylic acid cycle, and amino acid biosynthetic pathways that informed on pathway activity in central carbon metabolism, leading to fatty-acid and complex-lipid synthesis. The authors’ study emphasizes a prime advantage of combining multiple anal. techniques: the improved detection and annotation of metabolites. 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: 470-69-9Recommanded Product: 470-69-9).

Utilization of GC-MS untargeted metabolomics to assess the delayed response of glufosinate treatment of transgenic herbicide resistant (HR) buffalo grasses (Stenotaphrum secundatum L.) was written by Boonchaisri, Siriwat;Stevenson, Trevor;Dias, Daniel A.. And the article was included in Metabolomics in 2020.SDS of cas: 470-69-9 This article mentions the following:

A major aim of this present work is to characterize and evaluate the metabolic alterations which may arise from a genetic transformation of HR buffalo grasses by comprehensively using gas chromatog.-mass spectrometry (GC-MS) based untargeted metabolomics. Plants were either sprayed with 1, 5, 10 and 15% volume/volume of glufosinate to evaluate the visual injuries or submerged in 5% volume/volume of glufosinate 3 days prior to a GC-MS based untargeted metabolomics anal. Results identified 199 metabolites with only 6 of them (cis-aconitic acid, allantoin, cellobiose, glyceric acid, maltose and octadecanoic acid) found to be statistically significant (p < 0.05) between the HR and wild type buffalo grass varieties compared to the control experiment As expected, glufosinate treatment caused significant metabolic alterations in sensitive wild type, with the up-regulation of several amino acids (e.g. phenylalanine and isoleucine) which was likely due to glufosinate-induced senescence. The aminoacyl-tRNA biosynthetic pathway was identified as the most significant enriched pathway as a result of glufosinate effects because a number of its intermediates were amino acids. The current metabolomics analyses not only confirmed the effects of glufosinate to up-regulate free amino acid pools in the sensitive wild type but also several alterations in sugar, sugar phosphate and organic acid metabolism have been reported. 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: 470-69-9SDS of cas: 470-69-9).

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. 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.SDS of cas: 470-69-9

Dietary inulin increases Lactiplantibacillus plantarum strain Lp900 persistence in rats depending on the dietary-calcium level was written by Fuhren, Jori;Schwalbe, Markus;Roesch, Christiane;Nijland, Reindert;Wels, Michiel;Schols, Henk A.;Kleerebezem, Michiel. And the article was included in Applied and Environmental Microbiology in 2021.COA of Formula: C18H32O16 This article mentions the following:

Synbiotics are food supplements that combine probiotics and prebiotics to synergistically elicit health benefits in the consumer. Lactiplantibacillus plantarum strains display high survival during transit through the mammalian gastrointestinal tract and were shown to have health-promoting properties. Growth on the fructose polysaccharide inulin is relatively uncommon in L. plantarum, and in this study we describe FosE, a plasmid-encoded β-fructosidase of L. plantarum strain Lp900 which has inulin-hydrolyzing properties. FosE contains an LPxTG-like motif involved in sortase-dependent cell wall anchoring but is also (partially) released in the culture supernatant. In addition, we examined the effect of diet supplementation with inulin on the intestinal persistence of Lp900 in adult male Wistar rats in diets with distinct calcium levels. Inulin supplementation in high-dietary-calcium diets significantly increased the intestinal persistence of L. plantarum Lp900, whereas this effect was not observed upon inulin supplementation of the low-calcium diet. Moreover, intestinal persistence of L. plantarum Lp900 was determined when provided as a probiotic (by itself) or as a synbiotic (i.e., in an inulin suspension) in rats that were fed unsupplemented diets containing the different calcium levels, revealing that the synbiotic administration increased bacterial survival and led to higher abundance of L. plantarum Lp900 in rats, particularly in a low-calcium-diet context. Our findings demonstrate that inulin supplementation can significantly enhance the intestinal delivery of L. plantarum Lp900 but that this effect strongly depends on calcium levels in the diet.

In traditional use, Panax medicinal plants (ginseng, red ginseng, notoginseng, Panax japonicus, and Panacis majoris rhizoma) have different bioactivities from each other, even under different dosages, but their chem. compositions are very similar; so the question is, what is the primary effective substance induced the different efficacy, and how to identify them from a group of chem. constituents′. The goal of this research was to provide a strategy to determine the effective substance in Panax genus medicinal plants responsible for the anticoagulant response. This research used ultra-high performance liquid chromatog. coupled with mass spectrometry (UPLC-MS) to analyze the saponin chem. compositions of different concentration ethanol extraction of notoginseng and the ginseng genus medical plant 75% ethanol extraction (Panax ginseng, red ginseng, Panax japonicus, Panacis majoris rhizome), and used four coagulation factors (PT, TT, APTT, Fib) to evaluate the anticoagulant activity of the extracts Gray correlation anal. was applied to establish the spectral effect relationship and give the anticoagulant potency of different saponins. Network pharmacol. and mol. docking were adopted to clarify and verify the possible mechanisms of anticoagulant action. The results showed that the blood physiol. regulation activities of Panax medicinal plants were different according to the solvent concentration, processing, species and dosage. Overall, the most suitable solvent for extraction of SQ was 75% ethanol; At low dosage (10-100 mg/mL), the anticoagulant effect of Panax medical plants was: ZJS > ZZS > SQ > RS > HS, and at high doses (100-1000 mg/mL) was: SQ > ZJS > ZZS > RS > HS. GRA and mol. docking results showed the contribution of some components (NG-R2, NG-Fc/G-Ra1/G-Ra2, G-Rc, G-Rk3, and G-Rh4) to the whole anticoagulant activity of the drug were increased, while the effect of CS-IVa was just decreased with the increase of dosage; the anticoagulant effect of G-Rg3 (the main anticoagulant component) is mainly related to the targets F2, AR, RHO, ACR, MB, GZMB, B2M, CA2, CAT, and PAPOLA. This study determined the effective substance of anti-coagulation of ginseng genus herbal medicines and the regulation of different anticoagulant effects of TCM by changing various influencing conditions, including processing method, extraction method, and dose. It also provided an effective strategy for effective substances identification of multicomponent, multifunction, and multipurpose herbal medicine.
