Electromagnetic pollution cannot be ignored. Long-term low-dose electromagnetic field (EMF) exposure can cause central nervous system dysfunction without effective prevention. Male C57BL/6J mice (6-8 wk, 17-20 g) were used in this study. Depression-like and anxiety-like behaviors detected by behavioral experiments were compared among different treatments. 16S rRNA gene sequencing and non-targeted liquid chromatog.-mass spectrometry (LC-MS) metabolomics were used to explore the relationship between EMF exposure and heat acclimation (HA) effects on gut microbes and serum metabolites. Both EMF and HA regulated the proportions of p_Firmicutes and p_Bacteroidota. EMF exposure caused the proportions of 6 kinds of bacteria, such as g_Butyricicoccus and g_Anaerotruncus, to change significantly (p < 0.05). HA restored the balance of gut microbes that was affected by EMF exposure and the proportion of probiotics (g_Lactobacillus) increased significantly (p < 0.01). Serum metabolite anal. suggested that HA alleviated the disturbance of serum metabolites (such as cholesterol and -mannose) induced by EMF exposure. Both the metabolic KEGG pathways and PICRUSt functional anal. demonstrated that tryptophan metabolism, pyrimidine metabolism and amino acid biosynthesis were involved. EMF exposure not only led to depression-like neurobehavioral disorders, but also to gut microbiota imbalance. HA alleviated the depression features caused by EMF exposure. Based on the anal. of gut microbiota associated with serum metabolites, we speculated that gut microbiota might play a vital role in the cross-tolerance provided by HA.

The fresh fruits of black plum (Vitex doniana) were collected from several randomly selected trees in a farm site in Uromi metropolis, Esan North-East Local Government Area of Edo state and then processed into an extract in form of syrup. The sugars were identified using a combination of 1D 1H NMR and GC-MS. For the NMR anal., 5 mg of the sample was dissolved in deuterated DMSO (DMSO-d6), a common solvent for NMR anal. Then the sample, was analyzed with 1D 1H NMR at 500 MHz to obtain the spectrum showing the chem. shifts, peak multiplicity and coupling constants of the prospective sweeteners (sugars) in the sample. While characterization of the specific sugars in black plum fruit syrup was done using GC-MS spectroscopic techniques via derivatization. This method converts the sugars in the sample to the resp. trimethylsilyl-derivatives of the sugars, which are volatile and amenable for GC-MS anal. The sugars identified in Vitex doniana fruit syrup are fourteen and are presented based on the percentage of each sugar constituents and contribution to the sweetness profile of the syrup as obtained from their raw area percentage based on the total ion current. The sugars identified are Alpha.-DGlucopyranose (16.11%), Glucopyranose (11.19%), D-Glucose (11.15%), d-(+)-Xylose (8.95%), 2-Deoxy-pentose (8.92%), Glucofuranoside (6.84%), beta.-D-Galactopyranoside (6.37%), D-Fructose (6.16%), alpha.-DLArabinofuranoside (6.14%), alpha.-DL-Lyxofuranoside (4.85%), Ribitol (4.58%), 2-Keto-d-gluconic acid (3.62%), D-Xylofuranose (3.05%).

Author is De Pradhan, Ipsita; De, Bratati.

The fruits of Psidium guajava L., known as guava, are edible. The objectives of the study were to analyze the chem. composition of the skin, flesh, and pulp of two different Indian varieties of guava, e.g., Khaja and Allahabad at different stages of ripening (immature green, mature green, color turning, ripe, and overripe), and to study the pancreatic lipase (PL) inhibitory properties of the fruit extracts In total, 86 compounds were identified from different parts of the fruits. The different parts varied chem. with different stages of ripening in two varieties of guava. Major components contributing to the variation were ascorbic acid, catechin, epicatechin, shikimic acid, quinic acid, and some polyols and amino acids. Ascorbic acid content increased in color turning, ripe, and overripe stages. All the parts inhibited PL, highest activity being shown by the skin extracts The two varieties were also different in PL inhibitory activities. Thus, the study highlighted the nutritional as well as PL inhibiting activity beneficial to prevent fat absorption.

Carbohydrates are a renewable feedstock for the production of partially reduced polyols, but typical hydrogenolysis processes are unselective towards C-O bond cleavage at different positions and erase the stereocenters present in the feedstock. In this study, we demonstrate the synthesis of new types of acyclic polyols with controlled stereochem. from Me glycosides. Products include (2R,3S)-1,2,3,6-hexanetetrol, (2R,5S)-1,2,5,6-hexanetetrol, (2S,5S)-1,2,5-hexanetriol, and (4R,5S)-1,4,5-hexanetriol. Me glycosides are first selectively dehydrated and hydrogenated to Me dideoxy-glycosides as reported in previous work. These Me dideoxy-glycosides are then converted to hexane- triols and -tetrols over Pt-based catalysts in water in 80-95% yield via methoxy bond hydrolysis and hydrogenation. This route largely preserves the stereocenters of the remaining hydroxyl groups (>92% stereo-purity). The nature of the intermediates formed depends on the structure of the glycoside feedstock. 3,4-Dideoxy-glycosides can undergo loss of the C2-OH stereo-center due to an aldose-ketose isomerization reaction, which can be mitigated by using a bifunctional metal-acid catalyst to facilitate the reaction at lower temperature By demonstrating a new route to produce renewable polyols with controlled hydroxyl group positions and stereochem., this report lays the groundwork for further research into the applications of these mols. in the chem. industry.

Author is Chinyere, Imoisi; Julius, Iyasele U.; Samuel, Okhale E..

In traditional medicine and aromatherapy, use of essential oils and their flavor compounds have been known for the management of various human diseases. The flavor structures of black plum (Vitex doniana) sweet fruit are unavailable though widely eaten by natives. Therefore, this research is aimed at using spectroscopic techniques to identify the chem. structure of the specific flavor in the syrup responsible for its unique aroma and taste. Hydrodistillation (HD) in a Clevenger-type apparatus and GC-MS (HD-GC-MS) were used to extract the essential oil and analyze the volatile compounds (VOCs) resp. from Vitex doniana sweet fruit. 24 different volatile compounds (VOCs) were identified and grouped into eight classes of organic compounds comprising of 6 terpenes, 5 carboxylic acids, 3 ethers, 2 alcs., 2 ketones, 2 lactones, 2 aldehydes and 2 esters. It is noteworthy that GC-MS following hydrodistillation offers invaluable information about the aroma components of the fruit, because fingerprints of volatile compounds profiles using novel extraction methods are currently highly valued due to its importance to sensory properties of foodstuffs. Therefore, characterization of the aroma compounds as markers in putrefied and fresh fruits and their products are of great importance as a quality control parameter. The sugars were then identified using a combination of 1D 1H NMR and GC-MS. Characterization of the specific sugars in black plum fruit was done using GC-MS spectroscopic techniques via derivatization. This method converts the sugars in the sample to the resp. trimethylsilyl-derivatives of the sugars, which are thermally stable, volatile and amenable for GC-MS anal. The sugars identified are Alpha.-D-Glucopyranose, Glucopyranose, D-Glucose, d-(+)-Xylose, 2-Deoxy-pentose, Glucofuranoside, beta.-D-Galactopyranoside, D-Fructose, alpha.-DL-Arabinofuranoside, alpha.-DL-Lyxofuranoside, Ribitol, 2-Keto-d-gluconic acid, D-Xylofuranose and alpha.-D-Galactopyranose as obtained from their raw area percentage based on the total ion current. In conclusion, derivatization along with the coupling of GC with MS allows invaluable information about the composition and structure of sugars.

The article 《Evaluation and optimization of sample pretreatment for GC/MS-based metabolomics in embryonic zebrafish》 in relation to this compound, is published in Talanta. Let’s take a look at the latest research on this compound (cas:1824-94-8).

Metabolomics tactics have been applied in the research associated with embryonic zebrafish. However, the report regarding the evaluation of impacts of sample pretreatment on metabolomics results from zebrafish embryos is limited. Different data normalization approaches, extraction solvents, and extraction strategies for off-line derivatization gas chromatog. coupled with mass spectrometry-based metabolomics anal. of zebrafish eleutheroembryos were evaluated and optimized. When 4-chlorophenylalanine normalization, sample homogenization and pure methanol combined with ultrasonic extraction were conducted, better repeatabilities, higher signals and broader coverages of detected metabolites can be achieved. The recovery and standard deviation of most standards were at 82-121% and 6.6%-12%, resp., while the relative standard deviation of major detected metabolites ranged from 5.4% to 19%, indicating good extraction efficiencies and method precision. Under the developed method, 87 important endogenous metabolites such as citric acid and hypoxanthine were identified by universal databases or standards among 270 extracted metabolites, which consisted of sugars, amines, amino acids, nucleotides, fatty acids, and sterols. Therefore, the results could provide a proper pretreatment protocol for the anal. of wide-coverage metabolome in embryonic zebrafish. In addition, this study highlights the impact of normalization and extraction methods on the data quality of metabolomics anal.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called A 3-O-methylated heterogalactan from Pleurotus eryngii activates macrophages, published in 2019-02-15, which mentions a compound: 1824-94-8, mainly applied to Pleurotus heterogalactan macrophage MAPK NFkappaB TLR2 signaling; Heterogalactan; MAPKs; Macrophage; NF-κB; Pleurotus eryngii; TLR2, Related Products of 1824-94-8.

Mushroom-derived polysaccharides exhibit various biol. activities owing to their diverse structural features. Here, we purified a 3-O-methylated heterogalactan (WPEP-N-b, Mw 21.4 kDa) from the fruiting bodies of Pleurotus eryngii. WPEP-N-b is composed primarily of galactose (43.8%), mannose (39.3%), methyl-galactose (11.7%) and glucose (9.2%) residues, with the main chain being composed of α-1,6-linked D-Galp and 3-O-Me-D-Galp, branched at O-2 with single t-β-D-Manp as major the side chain. β-1,6-D-Glcp residues are present as minor components either in side-chains or backbone. WPEP-N-b increases macrophage phagocytosis and secretion of NO, TNF-α, IL-6 and IL-1β. Mechanistic studies demonstrate that WPEP-N-b promotes the degradation of IκB-α, and enhances phosphorylation of MAPKs and the NF-κB p65 subunit. Our results also indicate that this polysaccharide activates RAW264.7 cells via MAPK and NF-κB signaling pathways and the Toll-like receptor 2(TLR2). These results increase our understanding as to how mushroom-derived polysaccharides modulate the immunol. process.

Sulfated carbohydrates have been implicated in diverse biol. processes, with the position and extent of sulfation of a glycoside often playing important roles in determining the affinity and specificity of its binding to a biomol. partner. Methods for the site-selective introduction of sulfate groups to carbohydrates are thus of interest. Here, we describe the development of a diarylborinic acid-catalyzed protocol for selective sulfation of pyranoside derivatives at the equatorial position of a cis-1,2-diol group. This method, which employs the sulfur trioxide-trimethylamine complex as the electrophile, has been employed for installation of a sulfate group at the 3-position of a range of galacto- and mannopyranosides, including substrates having a free primary OH group. By using a full equivalent of the diarylborinic acid, selective syntheses of more complex mono-sulfated glycosides, namely, a 3′-sulfolactose derivative and 3′-sulfo-β-galactosylceramide, have been accomplished. Preliminary kinetics experiments suggested that the catalyst resting state is a tetracoordinate diarylborinic ester that reacts with the SO3 complex in the turnover-limiting step. Catalyst inhibition by the pyranoside sulfate product and trialkylamine byproduct of the reaction was demonstrated.
