On March 31, 2021, Hu, Xiuting; Song, Liping; Yang, Yuqi; Wang, Lei; Li, Yungao; Miao, Ming published an article.Formula: C12H24O11 The title of the article was Biosynthesis, structural characteristics and prebiotic properties of maltitol-based acceptor products. And the article contained the following:

To obtain novel prebiotic candidates, maltitol derivatives were obtained through alternansucrase-catalyzed reaction between sucrose and maltitol and their structural characteristics and in vitro fermentation were investigated. The reaction parameters, including the ratio of sucrose to maltitol, substrate concentration and reaction time, were optimized with the yield of 44.9% as well as 89.6 mg/mL of maltitol derivatives These maltitol derivatives included α-D-Glcp-(1 → 6)-α-D-Glcp-(1 → 4)-D-Gol (DP3-H), α-D-Glcp-(1 → 3)-α-D-Glcp- (1 → 6)-α-D-Glcp-(1 → 4)-D-Gol (DP4-H) and α-D-Glcp-(1 → 6)-α-D-Glcp-(1 → 3)-α- D-Glcp-(1 → 6)-α-D-Glcp-(1 → 4)-D-Gol (DP5-H). Similar to fructooligosaccharides, they showed the prebiotic activity. Specifically, the highest increase of Bifidobacteria was observed in the cultures supplemented with both DP4-H and DP5-H, whereas the most significant proliferation of Lactobacillus occurred in the culture supplemented with DP3-H. Moreover, fermentation of DP4-H resulted in the highest contents of butyrate and total short-chain fatty acids, which might be related to the highest α-(1 → 3) bond content. These results suggested that the maltitol-receptor products via alternansucrase-catalyzed acceptor reaction were the prebiotic ingredient candidates and the prebiotic activity of maltitol derivatives depended on the type of the glycosidic bond. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).Formula: C12H24O11

Kremieniewski, Marcin; Jasinski, Bartlomiej; Zima, Grzegorz; Kut, Lukasz published an article in 2021, the title of the article was Reduction of fractionation of lightweight slurry to geothermal boreholes.Reference of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol And the article contains the following content:

When designing the cement slurry for casing string cementing in geothermal boreholes, the appropriate thermal conductivity is selected. In the zone of geothermal water, where thermal energy is collected, cement slurry is used, from which the cement sheath has high thermal conductivity On the other hand, the remaining part of the opening is sealed with slurry, from which the cement sheath will reduce thermal energy losses through appropriate thermal insulation. Cement slurry with appropriate thermal insulation includes light insulating materials. However, the use of such additives is very problematic as they are fractionated due to their low d. Therefore, measures should be taken to prevent fractionation of the cement slurry for sealing geothermal boreholes. This article presents the results of research on fractionation of cement slurries for sealing geothermal boreholes. 12 slurries were used for the tests. Six of them are based on class A cement, and six based on class G cement. This action shows the differences in fractionation depending on the binder used. However, the main area of research is determining the effectiveness of counteracting fractionation by the means used for this purpose. As a result of the conducted works, a very good improvement of the cement slurry stability is obtained after the introduction of xanthan gum, as well as filtration perlite. These measures prevent fractionation, so that the cement slurry has a homogeneous structure, and the cement sheath provides the required thermal insulation in the geothermal well.

On June 23, 2020, Yokota, Hidetaka; Kadowaki, Miki; Matsuura, Tsutashi; Imanaka, Hiroyuki; Ishida, Naoyuki; Imamura, Koreyoshi published an article.Product Details of 585-88-6 The title of the article was The Use of a Combination of a Sugar and Surfactant to Stabilize Au Nanoparticle Dispersion against Aggregation during Freeze-Drying. And the article contained the following:

Drying a suspension of nanoparticles typically results in the irreversible aggregation of nanoparticles; however, solutions that contain unstable ingredients are often converted into dried powders to prolong their shelf lives. In this study, the use of a combination of a surface-active agent and sugar was investigated with regard to avoiding the aggregation of nanoparticles during drying. Suspensions of Au nanoparticles (~60 nm diameter, AuNPs) were freeze-dried in the presence of different combinations of various sugars with a surfactant. Sucrose monopalmitate (SEC16) was mainly used as the surfactant, based on a comparison of antiaggregation effects conferred by various surfactants. The freeze-dried AuNP suspension was then reconstituted, and the avoidance of AuNP aggregation was then examined The results demonstrated that the use of a combination of a small amount of SEC16 and sugar resulted in a greater redispersibility of AuNPs after freeze-drying than when the individual components were used. Repetition tests of freeze-drying and reconstitution were conducted. The sucrose/SEC16 mixture was freeze-dried on an electroless-plated Au film and then analyzed by IR spectroscopy. Strong interactions between SEC16 and the Au surface were detected, and these interactions appear to play a crucial role in the antiaggregation of AuNPs during freeze-drying. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).Product Details of 585-88-6

On April 13, 2021, Pandey, Renu; Collins, Meghan; Lu, Xiyuan; Sweeney, Shannon R.; Chiou, Jennifer; Lodi, Alessia; Tiziani, Stefano published an article.Electric Literature of 32462-30-9 The title of the article was Novel Strategy for Untargeted Chiral Metabolomics using Liquid Chromatography-High Resolution Tandem Mass Spectrometry. And the article contained the following:

Stereospecific recognition of metabolites plays a significant role in the detection of potential disease biomarkers thereby providing new insights in diagnosis and prognosis. D-Hdroxy/amino acids are recognized as potential biomarkers in several metabolic disorders. Despite continuous advances in metabolomics technologies, the simultaneous measurement of different classes of enantiomeric metabolites in a single anal. run remains challenging. Here, we develop a novel strategy for untargeted chiral metabolomics of hydroxy/amine groups (-OH/-NH2) containing metabolites, including all hydroxy acids (HAs) and amino acids (AAs), by chiral derivatization coupled with liquid chromatog.-high resolution tandem mass spectrometry (LC-HR-MS/MS). Diacetyl-tartaric anhydride (DATAN) was used for the simultaneous derivatization of-OH/-NH2 containing metabolites as well as the resulting diastereomers, and all the derivatized metabolites were resolved in a single anal. run. Data independent MS/MS acquisition (DIA) was applied to pos. identify DATAN-labeled metabolites based on reagent specific diagnostic fragment ions. We discriminated chiral from achiral metabolites based on the reversal of elution order of D and L isomers derivatized with the enantiomeric pair (±) of DATAN in an untargeted manner. Using the developed strategy, a library of 301 standards that consisted of 214 chiral and 87 achiral metabolites were separated and detected in a single anal. run. This approach was then applied to investigate the enantioselective metabolic profile of the bone marrow (BM) and peripheral blood (PB) plasma samples from patients with acute myeloid leukemia (AML) at diagnosis and following completion of the induction phase of chemotherapeutic treatment. The sensitivity and selectivity of the developed method enabled the detection of trace levels of the D-enantiomer of HAs and AAs in primary plasma patient samples. Several of these metabolites were significantly altered in response to chemotherapy. The developed LC-HR-MS method entails a valuable step forward in chiral metabolomics. The experimental process involved the reaction of H-Phg(4-OH)-OH(cas: 32462-30-9).Electric Literature of 32462-30-9

Seguido, Miguel Angel; Tarradas, Rosa Maria; Gonzalez-Ramila, Susana; Garcia-Cordero, Joaquin; Sarria, Beatriz; Bravo-Clemente, Laura; Mateos, Raquel published an article in 2022, the title of the article was Influence of 8-week daily consumption of a new product combining green coffee hydroxycinnamates and beta-glucans on polyphenol bioavailability in subjects with overweight and obesity.Recommanded Product: 621-37-4 And the article contains the following content:

Nutraceuticals based on plant extracts rich in polyphenols, as well as dietary fibers, are new means to fight overweight/obesity and associated diseases. However, to understand the potential effects of polyphenols on health it is critical to study their bioavailability and metabolic fate. Consumption of a green coffee phenolic extract (GCPE) in combination with oat beta-glucan (BG) could affect the pharmacokinetic profile of the main polyphenols present in coffee (hydroxycinnamates). Moreover, the regular intake of the combination could also induce changes. Nine overweight men and women consumed a novel nutraceutical product containing 300 mg of green coffee hydroxycinnamic acids and 2.5 g of BG twice a day for 8 wk. A pharmacokinetic study was carried out in blood and urine samples taken before (baseline) and at week 8 after the nutraceutical intervention, collecting samples at different times in a 0-24 h interval. Faecal samples were also obtained at 0 and 24 h after the intake of the nutraceutical at baseline and week 8. Phenolic metabolites were analyzed by LC-MS-QToF. Results showed that polyphenols were differentially absorbed and extensively metabolized throughout the gastrointestinal tract. An apparent reduction in the excretion of small intestinal metabolites was accompanied by a tendency to increase colonic metabolites after sustained intake (p = 0.052). In conclusion, continued consumption of the GCPE/BG nutraceutical appears to enhance the absorption of hydroxycinnamates by increasing the colonic bioavailability of their derived metabolites compared to baseline, although the regular intake of the nutraceutical did not modify the metabolite profile in any of the biol. samples. The experimental process involved the reaction of 3-Hydroxyphenylacetic acid(cas: 621-37-4).Recommanded Product: 621-37-4

On April 16, 2020, Wylde, J. J.; Taylor, G. N.; Sorbie, K. S.; Samaniego, W. N. published an article.Safety of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol The title of the article was Synthesis and Reaction Byproduct Characterization and Mechanistic Understanding of Hemiformal Based Hydrogen Sulfide Scavengers. And the article contained the following:

When hydrogen sulfide (H2S) gas is produced from oil reservoirs, it leads to a number of well-known problems relating to both metal corrosion and health and safety. Up to a certain concentration (~1000s of ppm in the gas phase) the H2S can be removed by adding a chem. “scavenger” to the system, which reacts with H2S to form less harmful byproducts. A range of different chem. species have been applied as H2S scavengers in petroleum production systems, operating through either oxidative or nonoxidative mechanisms; the former group includes such species as alk. sodium nitrite and hydrogen peroxide, and in the latter group triazine type scavengers have been very prominent. Although triazine based H2S scavengers have been hugely successful in practical and com. terms, there have been associated issues with the related byproducts from the scavenging reaction (discussed in this work). An alternative non-triazine chem. range of H2S scavengers that has emerged in recent years has been based on hemiacetal chemistries, where a hemiacetal is produced by the reaction of an alc. with an aldehyde. Where the aldehyde is formaldehyde, the resulting species are known as hemiformals. In this work, the synthetic chem. reaction pathway for hemiformals based on ethylene glycol and glycerol were studied. This work is novel in four major respects: (i) first, we examine hemiformal production via acid, base, and neutral catalysis systems; (ii) we perform detailed structural determinations of the oligomeric series thus produced (which are different) by analyzing the products by derivatized gas chromatog. mass spectrometry and making subsequent structural assignments; (iii) we then assess the effectiveness of these species as H2S scavenging using an industry standard multiphase test methodol. and make some correlation between their structure and performance; and (iv) finally, we studied the structures of product and byproducts of the scavenging reaction both before and after the scavenging reaction with H2S. This latter part of the study examines issues of byproduct structure early in the development of these newer products in order to address any problems that may be encountered “up front”. This greatly facilitates our application of using hemiformals as fully optimized non-triazine based scavengers by addressing byproduct chem. anal. of these relatively new H2S scavenger systems.

Zhang, Zhanjiang; Shen, Guang; Yang, Yihua; Li, Cui; Chen, Xiaoying; Yang, Xiaonan; Guo, Xiaoyun; Miao, Jianhua; Li, Li; Lei, Ming published an article in 2022, the title of the article was Metabolic and Transcriptomic Analyses Reveal the Effects of Ethephon on Taraxacum kok-saghyz Rodin.Category: alcohols-buliding-blocks And the article contains the following content:

The roots of Taraxacum kok-saghyz Rodin (TKS) are well-known and valued for their rubber-producing ability. Therefore, research on the anal. and detection of metabolites from the roots of TKS have been reported in previous studies. However, all of these studies have the shortcoming of focusing on only the rubber of TKS, without profiling the other metabolites in a systematic and comprehensive way. Here, the primary and secondary metabolites from the leaves of TKS were investigated using UPLC-ESI-MS/MS, and a total of 229 metabolites were characterized. Carboxylic acid derivatives, fatty acyls, phenols, and organooxygen compounds were found to be the major metabolites of TKS. The transcriptome data indicated that ribosomal, glycolysis/gluconeogenesis, phenylpropanoid biosynthesis, and linoleic acid metabolism genes were significantly differentially expressed. This study is the first to report the differences in the metabolic and transcriptome profiles of TKS leaves under exogenous ethephon spray, which improves our understanding of the main metabolites and their mol. mechanisms in TKS leaves. The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Category: alcohols-buliding-blocks

Bu, Ting; Zhang, Ming; Lee, Sun-Hee; Cheong, Yu Eun; Park, Yukyung; Kim, Kyoung Heon; Kim, Dongwon; Kim, Sooah published an article in 2022, the title of the article was GC-TOF/MS-Based Metabolomics for Comparison of Volar and Non-Volar Skin Types.Reference of 2,3-Dihydroxypropanoic acid And the article contains the following content:

Skin has heterogenous identities on different body sites despite similar cellular compositions There are two types of skin, volar (palmoplantar) and non-volar (dorsal), which are characterized by epidermal thickness, pigmentation, and presence of hair follicles. However, the mechanisms underlying the development of these different skin types remain unclear. To investigate these, we profiled the cellular metabolites of volar and non-volar skin in mice using gas chromatog.-time-of-flight/mass spectrometry (GC-TOF/MS), and further assessed the metabolic differences between them. In total, 96 metabolites from both volar and non-volar skin of mice were identified using the BinBase database system. Metabolomics anal. revealed important differences associated with amino acid metabolism (phenylalanine, tyrosine, and tryptophan biosynthesis; aspartate and glutamate metabolism), sugar metabolism (pentose phosphate pathway), and nucleotide metabolism (pyrimidine metabolism) in volar skin. Fifty metabolites were identified as potential biomarkers differentiating the physiol. characteristics of these skin types. Of these, nine were highly increased whereas 41 were significantly decreased in volar skin compared with those in non-volar skin. Overall, these results provide valuable information for understanding the metabolic differences between volar and non-volar skin.

On July 31, 2022, de Falco, Bruna; Grauso, Laura; Fiore, Alberto; Bonanomi, Giuliano; Lanzotti, Virginia published an article.Reference of 2,3-Dihydroxypropanoic acid The title of the article was Metabolomics and chemometrics of seven aromatic plants: Carob, eucalyptus, laurel, mint, myrtle, rosemary and strawberry tree. And the article contained the following:

Arbutus unedo L. (strawberry tree), Ceratonia siliqua L. (carob), Eucalyptus camaldulensis Dehnh. (eucalyptus), Laurus nobilis L. (laurel), Mentha aquatica L. (water mint), Myrtus communis L. (common myrtle), and Rosmarinus officinalis L. (rosemary) are aromatic plants from the Mediterranean region whose parts and preparations are used for their nutritional properties and health benefits. To evaluate and compare the metabolites profile, total phenol content (TPC), and antioxidant activity of plant leaves for their future use. Gas chromatog.-mass spectrometry (GC-MS) was used for metabolomics. Data comparison was performed by chemometrics. Polar and apolar extracts were analyzed using untargeted GC-MS metabolomics followed by chemometrics (principal component anal., heatmap correlation and dendrogram) to identify, quantify and compare the major organic compounds in the plants. Addnl., NMR (NMR) spectroscopy was used for the laurel polar extract to identify D-gluco-L-glycero-3-octulose whose presence was unclear from the GC-MS data. TPC and antioxidant assays were performed using classical methods (Folin-Ciocalteu, 2,2-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH)) and correlated to the phytochem. profiles. Forty-three metabolites were identified including amino acids, organic acids, carbohydrates, phenols, polyols, fatty acids, and alkanes. Eight metabolites (D-fructose, D-glucose, D-mannose, gallic acid, quinic acid, myo-inositol, palmitic and stearic acids) were in common between all species. D-Gluco-L-glycero-3-octulose (37.29 ± 1.19%), D-pinitol (31.33 ± 5.12%), and arbutin (1.30 ± 0.44%,) were characteristic compounds of laurel, carob, and strawberry tree, resp. Carob showed the highest values of TPC and antioxidant activity. GC-MS metabolomics and chemometrics analyses are fast and useful methods to determine and compare the metabolomics profiling of aromatic plants of food and industrial interest.

Zhao, Shuang; Fu, Haoshuang; Zhou, Tianhui; Cai, Minghao; Huang, Yan; Gan, Qinyi; Zhang, Chenxi; Qian, Cong; Wang, Jiexiao; Zhang, Zhenglan; Wang, Xiaolin; Xiang, Xiaogang; Xie, Qing published an article in 2022, the title of the article was Alteration of bile acids and omega-6 PUFAs are correlated with the progression and prognosis of drug-induced liver injury.Electric Literature of 473-81-4 And the article contains the following content:

Drug-induced liver injury (DILI) is one of the leading causes of liver failure with some of the patients progressed to chronic DILI. The mechanisms underlying the severity and chronicity of DILI are poorly elucidated and the biomarkers are limited. Metabolites and gut microbiota played a crucial role in the development of various liver diseases. Herein, a systematic anal. of serum metabolites and gut microbiota was performed in DILI patients, aiming to identify metabolites correlated with the progression and clin. prognosis of DILI. Various serum metabolites were quantitated using a metabolite array technol. in this prospective study. Gut microbiome compositions and the expression profiles of liver genes were determined in patients with DILI and healthy controls. Metabolomic anal. revealed that bile acids (BAs) and polyunsaturated fatty acids (PUFAs) were closely related to DILI severity and chronicity resp. The ratios of serum primary/secondary BAs and omega-6/omega-3 PUFAs were elevated in DILI patients. A model established by adrenic acid (AdA) and aspartic acid (Asp) exerts good performance for predicting the chronicity of DLIL. Hepatic transcriptome revealed enhanced expression of PUFA peroxidation and suppressed expression of BA synthesis related genes in DILI patients. In addition, Lactic acid bacteria and BA converting bacteria were increased in gut of DILI patients. Besides, elevated serum malondialdehyde (MDA) and fibroblast growth factor 19 (FGF19) was observed in DILI patients. BAs and PUFAs could be potent markers for the severity and chronicity of DILI resp. The panel of AdA and Asp could be ideal predictive model for the risk of chronicity at the acute stage of DILI. Gut microbiota might act as a neg. feedback mechanism to maintain the homeostasis of BAs and PUFAs via FGF19 signalling and PUFA saturation, resp. Our study revealed novel biomarkers for severe and chronic DILI and provided new therapeutic targets for DILI.
