On June 1, 2022, Ilhan, Zehra Esra; Brochard, Vincent; Lapaque, Nicolas; Auvin, Stephane; Lepage, Patricia published an article.Electric Literature of 585-88-6 The title of the article was Exposure to anti-seizure medications impact growth of gut bacterial species and subsequent host response. And the article contained the following:

Anti-seizure medications (ASMs) are the first line of treatment for seizure control in children with epilepsy. Cumulative evidence suggests an imbalanced gut microbiota in refractory epilepsy patients. We systematically investigated the differential antimicrobial impacts of nine ASM active ingredients, seven common excipients of ASMs, and four syrup formulations on core early-life gut microbiota strains. Addnl., we evaluated the toxicity and gene expression profiles of HT-29 colon epithelial cells when exposed to active ingredients with or without bacterial supernatants. The physicochem. structure of ASM active ingredients and bacterial phylogeny were found to be related to ASM toxicity. Carbamazepine, lamotrigine, and topiramate reduced the growth of more than ten strains along with syrup excipient propyl-paraben. Various artificial sweeteners present in ASM formulations stimulated the growth of gut bacterial strains. The active ingredients that were more toxic to bacterial strains also exhibited toxicity towards HT-29 cells, yet Bifidobacterium longum supernatant reduced cytotoxic effects of carbamazepine and lamotrigine. Akkermansia muciniphila or mixed community supernatants reduced the expression of drug resistance genes in HT-29 cell lines. In summary, our results indicate that several ASM active ingredients and their excipients regulate the growth of gut bacterial strains in a species-specific manner. Interactions between ASMs and gut epithelial cells might be modulated by gut microbial metabolites. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).Electric Literature of 585-88-6

Yuan, Li-Ming; Ma, Wei; Xu, Mei; Zhao, Hui-Lin; Li, Yuan-Yuan; Wang, Rui-Lin; Duan, Ai-Hong; Ai, Ping; Chen, Xue-Xian published an article in 2017, the title of the article was Optical resolution and mechanism using enantioselective cellulose, sodium alginate and hydroxypropyl-β-cyclodextrin membranes.Computed Properties of 32462-30-9 And the article contains the following content:

Chiral solid membranes of cellulose, sodium alginate, and hydroxypropyl-β-cyclodextrin were prepared for chiral dialysis separations After optimizing the membrane material concentrations, the membrane preparation conditions and the feed concentrations, enantiomeric excesses of 89.1%, 42.6%, and 59.1% were obtained for mandelic acid on the cellulose membrane, p-hydroxy phenylglycine on the sodium alginate membrane, and p-hydroxy phenylglycine on the hydroxypropyl-β-cyclodextrin membrane, resp. To study the optical resolution mechanism, chiral discrimination by membrane adsorption, solid phase extraction, membrane chromatog., high-pressure liquid chromatog. ultrafiltration were performed. All of the exptl. results showed that the first adsorbed enantiomer was not the enantiomer that first permeated the membrane. The crystal structures of mandelic acid and p-hydroxy phenylglycine are the racematic compounds We suggest that the chiral separation mechanism of the solid membrane is “adsorption – association – diffusion,” which is able to explain the optical resolution of the enantioselective membrane. This is also the first report in which solid membranes of sodium alginate and hydroxypropyl-β-cyclodextrin were used in the chiral separation of p-hydroxy phenylglycine. The experimental process involved the reaction of H-Phg(4-OH)-OH(cas: 32462-30-9).Computed Properties of 32462-30-9

Nesterova, Oksana V.; Nesterov, Dmytro S.; Vranovicova, Beata; Boca, Roman; Pombeiro, Armando J. L. published an article in 2018, the title of the article was Heterometallic CuIIFeIII and CuIIMnIII alkoxo-bridged complexes revealing a rare hexanuclear M6(μ-X)7(μ3-X)2 molecular core.Product Details of 2160-93-2 And the article contains the following content:

The novel hexanuclear complexes [Cu4Fe2(OH)(Piv)4(tBuDea)4Cl]·0.5CH3CN (1) and [Cu4Mn2(OH)(Piv)4(tBuDea)4Cl] (2) were prepared through one-pot self-assembly reactions of copper powder and iron(II) or manganese(II) chloride with N-tert-butyldiethanolamine (H2tBuDea) and pivalic acid (HPiv) in acetonitrile. Crystallog. studies revealed the uncommon mol. core type M6(μ-X)7(μ3-X)2 in 1 and 2, which can be viewed as a combination of two trimetallic M3(μ-X)2(μ3-X) fragments joined by three bridging atoms. The anal. and classification of the hexanuclear complexes having a M3(μ-X)2(μ3-X) moiety as a core forming fragment using data from the Cambridge Structural Database (CSD) were performed. Variable-temperature (1.8-300 K) magnetic susceptibility measurements of 1 showed a decrease of the effective magnetic moment value at low temperature, indicative of antiferromagnetic coupling between the magnetic centers (JFe-Cu/hc = -6.9 cm-1, JCu-Cu/hc = -4.1 cm-1, JFe-Fe/hc = -24.2 cm-1). Complex 1 acts as a catalyst in the reaction of mild oxidation of cyclohexane with H2O2, showing the yields of products, cyclohexanol and cyclohexanone, up to 17% using pyrazinecarboxylic acid as a promoter. In the oxidation of cis-1,2-dimethylcyclohexane with m-chloroperoxybenzoic acid (m-CPBA), 70% of retention of stereoconfiguration was observed for tertiary alcs. Compound 1 also catalyzes the amidation of cyclohexane with benzamide. In all three catalytic reactions the byproducts were investigated in detail and discussed.

Pagano, Sandro; Montana, Giuseppe; Wickleder, Claudia; Schnick, Wolfgang published an article in 2009, the title of the article was Urea Route to Homoleptic Cyanates-Characterization and Luminescence Properties of [M(OCN)2(urea)] and M(OCN)2 with M = Sr, Eu.Safety of 2-Methyl-2-propylpropane-1,3-diol And the article contains the following content:

A novel approach for the synthesis of urea complexes and homoleptic cyanates of alk. earth metals and Eu is described. The compounds were fully characterized, including their magnetism and temperature-dependent luminescence properties. A novel approach for the synthesis of urea complexes and homoleptic cyanates of alk. earth metals and Eu is described. Direct reaction of urea with elemental Sr or Eu in closed ampuls at temperatures >120° yields [M(OCN)2(urea)] with M = Sr, Eu. According to single-crystal x-ray diffraction, the isotypic complexes exhibit a layer structure ([Eu(OCN)2(urea)]: space group P21/c, a 7.826(2), b 7.130(1), c 12.916(3) Å, β 99.76(3)°, Z = 4). Also, they were characterized by vibrational spectroscopy, thermal anal., magnetic measurements, and photoluminescence studies. Thermal treatment of [M(OCN)2(urea)] to 160-240° affords evaporation of urea and the subsequent formation of solvent-free homoleptic cyanates of Sr and Eu. The crystal structures of Sr(OCN)2 and Eu(OCN)2 were determined from x-ray powder diffraction data and refined by the Rietveld method. Both compounds crystallize in the orthorhombic space group Fddd and adopt the Sr(N3)2 type structure (Sr(OCN)2: a 6.1510(4), b 11.268(1), c 11.848(1) Å; Eu(OCN)2: a 6.1514(6), b 11.2863(12), c 11.8201(12) Å). The cyanates are stable up to 450°. Above 500° β-Sr(CN)2 and Eu2O2(CN)2 are formed. Excitation and emission spectra of [Eu(OCN)2(urea)], [Sr(OCN)2(urea)]:Eu2+, Eu(OCN)2, Sr(OCN)2:Eu2+ at different temperatures are reported. A strong green emission for all examined Eu-containing compounds due to a 4f6 5d1-4f7 transition is observed at low temperatures The luminescence properties are discussed in detail and are comparable to those of thiocyanates. Compared to the latter, a blue shift of the emission bands is observed due to the higher ionicity. The experimental process involved the reaction of 2-Methyl-2-propylpropane-1,3-diol(cas: 78-26-2).Safety of 2-Methyl-2-propylpropane-1,3-diol

On May 15, 2022, Yan, Jun; Chen, Qi; Tian, Lei; Li, Kang; Lai, Wenqing; Bian, Liping; Han, Jie; Jia, Rui; Liu, Xiaohua; Xi, Zhuge published an article.Safety of 3-Hydroxyphenylacetic acid The title of the article was Intestinal toxicity of micro- and nano-particles of foodborne titanium dioxide in juvenile mice: Disorders of gut microbiota-host co-metabolites and intestinal barrier damage. And the article contained the following:

The wide use of TiO2 particles in food and the high exposure risk to children have prompted research into the health risks of TiO2. We used the microbiome and targeted metabolomics to explore the potential mechanism of intestinal toxicity of foodborne TiO2 micro-/nanoparticles after oral exposure for 28 days in juvenile mice. Results showed that the gut microbiota-including the abundance of Bacteroides, Bifidobacterium, Lactobacillus, and Prevotella-changed dynamically during exposure. The organic inflammatory response was activated, and lipopolysaccharide levels increased. Intestinal toxicity manifested as increased mucosal permeability, impaired intestinal barrier, immune damage, and pathol. changes. The expression of antimicrobial peptides, occludin, and ZO-1 significantly reduced, while that of JNK2 and Src/pSrc increased. Compared with micro-TiO2 particles, the nano-TiO2 particles had strong toxicity. Fecal microbiota transplant confirmed the key role of gut microbiota in intestinal toxicity. The levels of gut microbiota-host co-metabolites, including pyroglutamic acid, L-glutamic acid, phenylacetic acid, and 3-hydroxyphenylacetic acid, changed significantly. Significant changes were observed in the glutathione and propanoate metabolic pathways. There was a significant correlation between the changes in gut microbiota, metabolites, and intestinal cytokine levels. These, together with the intestinal barrier damage signaling pathway, constitute the network mechanism of the intestinal toxicity of TiO2 particles. The experimental process involved the reaction of 3-Hydroxyphenylacetic acid(cas: 621-37-4).Safety of 3-Hydroxyphenylacetic acid

On September 30, 2013, Friis, Ulrik F.; Menne, Torkil; Flyvholm, Mari-Ann; Bonde, Jens Peter E.; Johansen, Jeanne D. published an article.Related Products of 4719-04-4 The title of the article was Occupational allergic contact dermatitis diagnosed by a systematic stepwise exposure assessment of allergens in the work environment. And the article contained the following:

Background. Information on the presence of contact allergens and irritants is crucial for the diagnosis of occupational contact dermatitis. Ingredient lists and Material Safety Datasheets (MSDSs) may be incomplete. Objectives. To evaluate the workability of a systematic exposure assessment in consecutive patients with suspected occupational contact dermatitis, and to study how it could potentially aid correct diagnostic classification. Methods. A tool for systematic stepwise assessment of exposures in the work environment was developed, consisting of six steps spanning medical history and workplace visits. The program included 228 consecutive patients diagnosed with occupational contact dermatitis: all patients underwent a clin. examination, the stepwise exposure assessment, and extensive patch and prick testing. Results. Of the participants. 48.2% were classified as having occupational allergic contact dermatitis. The diagnosis was made at the stepwise exposure assessment for 50.0% of patients at Step 1 (medical history) and for 34.5% at Step 2 (ingredient labeling/MSDS). We found 132 different occupational allergens of relevance to the patients’ eczema of these, 78.0% were allergens not included in the European baseline series. Conclusions. Systematic stepwise exposure assessment provides information that results in the identification of occupational allergies caused by allergens not included in the European baseline series in a substantial number of patients. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Related Products of 4719-04-4
