Gold(I)-Catalyzed Intermolecular Rearrangement Reaction of Glycosyl Alkynoic β-Ketoesters for the Synthesis of 4-O-Glycosylated 2-Pyrones was written by Liu, Rongkun;Li, Xiaoqian;Li, Xiaona;Wang, Jiazhe;Yang, You. And the article was included in Journal of Organic Chemistry in 2019.Reference of 582-52-5 This article mentions the following:

A new gold(I)-catalyzed rearrangement reaction with glycosyl alkynoic β-ketoesters as substrates is developed. The rearrangement reactions under the catalysis of PPh₃AuOTf proceeded smoothly to afford a range of 4-O-glycosylated 2-pyrones. Based on the isolation of the 4-hydroxy-2-pyrone derivative generated from the departure of the leaving group and the competitive reaction, a plausible mechanism of the gold(I)-catalyzed intermol. rearrangement reactions is proposed. 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. Tetrahydrofuran (THF) is a Lewis base that bonds to a variety of Lewis acids such as I2, phenols, triethylaluminum and bis(hexafluoroacetylacetonato)copper(II). 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.Reference of 582-52-5

Red Algal Molecules – Synthesis of Methyl Neo-β-carrabioside and Its S-Linked Variant via Two Synthetic Routes: A Late Stage Ring Closure and Using a 3,6-Anhydro-D-galactosyl Donor was written by Wallace, Michael D.;Ficko-Blean, Elizabeth;Stubbs, Keith A.. And the article was included in Journal of Organic Chemistry in 2020.COA of Formula: C12H20O6 This article mentions the following:

Me neo-β-carrabioside has been synthesized for the first time, employing either a late stage ring closure to install the required 3,6-anhydro-bridge or a suitable 3,6-anhydro-galactosyl donor to form the unfavored 1,2-cis-equatorial α-linkage. Using the late stage ring closure approach, an S-linked analog of Me neo-β-carrabioside was also realized. These compounds have applications in the identification and characterization of marine bacterial exo-α-3,6-anhydro-D-galactosidases that have specific activity on red algal neo-carrageenan oligosaccharides, such as those found in both family 127 and 129 of the glycoside hydrolases. In addition a biochem. assay using the synthesized Me neo-β-carrabioside and the marine bacterial exo-α-3,6-anhydro-D-galactosidase ZgGH129 demonstrates that the min. substrate unit for the enzyme is neo-β-carrabiose. 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: 582-52-5COA of Formula: C12H20O6).

Clustering bitter compounds via individual sensitivity differences: evidence supporting multiple receptor-transduction mechanisms was written by Delwiche, Jeannine F.;Buletic, Zivjena;Breslin, Paul A. S.. And the article was included in ACS Symposium Series in 2002.Computed Properties of C28H38O19 This article mentions the following:

Although it had been well documented that people varied widely in their sensitivities to bitter compounds, the intercorrelation of these sensitivities remained unknown. By clustering bitter compounds representative of different chem. classes as a function of individual sensitivities, it was possible to infer the number and variety of potential bitterness transduction systems involved in bitter perception. Results indicated that bitter compounds could be grouped into two general groups, neither of which contains PROP (n-propylthiouracil). There are also subjects who possess diminished absolute sensitivity to bitter stimuli, but do not differ in their relative sensitivities to these 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: 126-14-7Computed Properties of C28H38O19).

Side Chain Conformation and Its Influence on Glycosylation Selectivity in Hexo- and Higher Carbon Furanosides was written by Siyabalapitiya Arachchige, Sameera;Crich, David. And the article was included in Journal of Organic Chemistry in 2022.HPLC of Formula: 582-52-5 This article mentions the following:

We describe the synthesis and side chain conformational anal. of a series of four 6-deoxy-2,3,5-tri-O-benzyl hexofuranosyl donors with the D-gluco, L-ido, D-altro, and L-galacto configurations. The conformation of the exocyclic bond of these compounds depends on the relative configuration of the point of attachment of the side chain to the ring and of the two flanking centers and can be predicted on that basis analogously to the heptopyranose analogs. Variable-temperature NMR (VT NMR) spectroscopy of the activated donors reveals complex, configuration-dependent mixtures of intermediates that we interpret in terms of fused and bridged oxonium ions arising from participation by the various benzyl ethers. The increased importance of ether participation in the furanoside series compared to the pyranosides is discussed in terms of the reduced stabilization afforded to furanosyl oxocarbenium ions by covalent triflate formation. The stereoselectivities of the four donors are discussed on the basis of the benzyl ether participation model. 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) is a Lewis base that bonds to a variety of Lewis acids such as I2, phenols, triethylaluminum and bis(hexafluoroacetylacetonato)copper(II). Commercial tetrahydrofuran contains substantial water that must be removed for sensitive operations, e.g. those involving organometallic compounds.

A formulation for suppressing bitter taste in the human oral cavity was written by Smutzer, Gregory;Cherian, Silvy;Patel, Dhruti;Lee, Brian Sang;Lee, Kevin;Sotelo, Angelica R.;Mitchell, Kurt-Dale W.. And the article was included in Physiology & Behavior in 2020.SDS of cas: 126-14-7 This article mentions the following:

Stearic acid microspheres were prepared that successfully encapsulated the bitter taste stimulus sucrose octaacetate. Sucrose octaacetate microspheres were then embedded in rapidly dissolving edible films for psychophys. studies. Taste intensity, taste quality, and hedonic responses for edible taste strips that contained encapsulated sucrose octaacetate along with masking and flavoring agents in edible taste films were then obtained. These results were compared to three formulations that included either unencapsulated sucrose octaacetate in the polymer film, unencapsulated sucrose octatacetate and masking and flavoring agents in the film, or encapsulated sucrose octaacetate with no additives in the film. Of the four formulations, microsphere-containing edible films that included bitter taste masking and flavoring agents masked the bitter taste of sucrose octaacetate most effectively over a 60-s time period. Participants also reported favorable (pos.) hedonic responses with this formulation. The encapsulation of bitter taste stimuli in lipid microspheres and incorporating these microspheres in rapidly dissolving edible films that contain masking and flavoring agents, significantly decreased bitter taste perception. This approach is a promising mechanism for masking bitter taste perception and may represent a model for increasing drug acceptance and drug compliance in both the young and the elderly. 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: 126-14-7SDS of cas: 126-14-7).

Effects of kestose on gut mucosal immunity in an atopic dermatitis mouse model was written by Kim, Ha-Jung;Lee, Seung-Hwa;Go, Han-Na;Ahn, Jae-Rin;Kim, Hye-Jung;Hong, Soo-Jong. And the article was included in Journal of Dermatological Science in 2018.Application of 470-69-9 This article mentions the following:

Atopic dermatitis (AD) is recently increasing among populations, but the underlying mechanisms remain controversial. Interactions between the gut microbiota and mucosal immunity are considered to be a crucial etiol. Fructooligosaccharide (FOS), prebiotics have been reported as activators of the gut microbiota. The aim of this study was to investigate the effects of kestose, the smallest FOS and FOS on atopic dermatitis in mice. An AD mouse model was developed by (ovalbumin) epidermal sensitization using BALB/c mice. Kestose (1%, 5%, and 10%) or FOS (5%, pos. control) was orally administered throughout the study. In comparison with the values observed for the control AD mice, transepidermal water loss (TEWL), clin. score, and skin inflammation on histopathol. were significantly decreased by the oral administration of kestose. Total IgE, thymic stromal lymphopoietin (TSLP) in skin, and IL-4 were also suppressed by this administration. In addition, the population of CD4⁺Foxp3⁺ cells in mesenteric lymph nodes (MLNs) and acetate concentrations in feces were significantly increased by kestose treatment. These findings suggest that kestose activates the gut immune system to induce the tolerance against allergic skin inflammations in AD. 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).

The distinctiveness of ionic and nonionic bitter stimuli was written by Frank, Marion E.;Bouverat, Brian P.;MacKinnon, Bruce I.;Hettinger, Thomas P.. And the article was included in Physiology & Behavior in 2004.Safety 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 This article mentions the following:

The diverse chem. structures of stimuli that are bitter to humans suggest a need for multiple bitter receptors. Reactions of golden hamsters (Mesocricetus auratus) to 1 mM quinine hydrochloride, 3 mM denatonium benzoate, 180 mM magnesium sulfate, 30-100 mM caffeine, and 1-1.5 mM sucrose octaacetate (SOA) were studied to address whether there are multiple sensations elicited by bitter stimuli. Methods included behavioral generalization of LiCl-induced conditioned taste aversions (CTAs), intake preference tests, and electrophysiol. recordings from the chorda tympani (CT) nerve. The five compounds, all bitter to humans, were all innately aversive to hamsters. CTA for the ionic quinine·HCl, denatonium benzoate, and MgSO₄ mutually cross-generalized and these ionic compounds were effective CT stimuli. Yet, the hamsters were much less sensitive to denatonium than humans, requiring a 100,000 times higher concentration for detection. CTA for nonionic caffeine and SOA did not cross-generalize to quinine or the other two ionic stimuli and these nonionic compounds were not effective CT stimuli. SOA and caffeine may elicit aversive reflexes or systemic reactions rather than taste sensations in the animals. Thus, the three ionic and two nonionic compounds form sep. aversive stimulus classes in hamsters, neither of which appears to be a close homolog of the human bitter taste. 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: 126-14-7Safety 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).

Chemical composition, phenolic content and antioxidant capacity of Haloxylon scoparium extracts was written by Haida, S.;Kribii, A.. And the article was included in South African Journal of Botany in 2020.Recommanded Product: (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 This article mentions the following:

This work is part of the valorization of the Haloxylon scoparium plant, belonging to the Chenopodiaceae family and native to southeastern of Morocco. The aim of the present work is to study the chem. composition of this plant, to estimate the phenolic compounds contents of its extracts and to evaluate their antioxidant powers. After extraction by maceration of the aerial and root part of Haloxylon scoparium, the extracts obtained are fractionated by liquid-liquid extraction using solvents of different polarities. The best extraction yield is obtained in the aerial part 23.54% against 10.99% for the root part. The anal. carried out by the coupling of gas chromatog. with mass spectrometry (GC-MS) shows that the root part contains mainly carbohydrates, however the aerial part consists mainly of alkaloids. The total polyphenol content obtained in the root part 69.86 mg/gEAG (mg/g of gallic acid) is significantly higher than that in the aerial part 56.79 mg/g EAG. The hydrolysable tannins are the predominant polyphenols of the root part of Haloxylon scoparium corresponding to 83.87 mg/g EAT (mg/g of tannic acid). The antioxidant activity of the various extracts obtained is evaluated by two methods: the DPPH (1,1-diphenyl-2-picryl hydrazyl) free radical scavenging test and the ferric reducing antioxidant power (FRAP). The examination of the inhibitory concentration values shows that the butanolic extract of the root part is the most active with values of IC₅₀ = 0.06 mg/mL and IC_0.5 = 0.19 mg/mL resp. for the DPPH and FRAP tests. The other extracts also showed a very interesting potential as antioxidants.
