Zhang, Xiyu; Zheng, Cuiting; Gao, Zhenqiang; Chen, Hongyu; Li, Kai; Wang, Lingling; Zheng, Yuanyuan; Li, Chunjia; Zhang, Hongjia; Gong, Ming; Zhang, Hongbing; Meng, Yan published the artcile< SLC7A11/xCT Prevents Cardiac Hypertrophy by Inhibiting Ferroptosis>, Name: Ethyl 3-amino-4-(cyclohexylamino)benzoate, the main research area is slc7a11 xCT cardiac hypertrophy ferroptosis; Angiotensin II; Cardiac hypertrophy; Ferroptosis; xCT.

Systemic hypertension may induce adverse hypertrophy of the left cardiac ventricle. Pathol. cardiac hypertrophy is a common cause of heart failure. We investigated the significance of ferroptosis repressor xCT in hypertrophic cardiomyopathy. XCT expression in angiotensin II (Ang II)-treated mouse hearts and rat cardiomyocytes was determined using qRT-PCR and Western blotting. Cardiac hypertrophy was induced by Ang II infusion in xCT knockout mice and their wildtype counterparts. Blood pressure, cardiac pump function, and pathol. changes of cardiac remodeling were analyzed in these mice. Cell death, oxidative stress, and xCT-mediated ferroptosis were examined in Ang II-treated rat cardiomyocytes. After Ang II infusion, xCT was downregulated at day 1 but upregulated at day 14 at both mRNA and protein levels. It was also decreased in Ang II-treated cardiomyocytes, but not in cardiofibroblasts. Inhibition of xCT exacerbated cardiomyocyte hypertrophy and boosted the levels of ferroptosis biomarkers Ptgs2, malondialdehyde, and reactive oxygen species induced by Ang II, while overexpression of xCT opposed these detrimental effects. Furthermore, knockout of xCT aggravated Ang II-mediated mouse cardiac fibrosis, hypertrophy, and dysfunction. Ferrostatin-1, a ferroptosis inhibitor, alleviated the exacerbation of cardiomyocyte hypertrophy caused by inhibiting xCT in cultured rat cells or ablating xCT in mice. XCT acts as a suppressor in Ang II-mediated cardiac hypertrophy by blocking ferroptosis. Pos. modulation of xCT may therefore represent a novel therapeutic approach against cardiac hypertrophic diseases.

Orbegozo, Thomas; de Vries, Johannes G.; Kroutil, Wolfgang published the artcile< Biooxidation of Primary Alcohols to Aldehydes through Hydrogen Transfer Employing Janibacter terrae>, COA of Formula: C19H34O2, the main research area is Janibacter oxidation primary alc.

Chemoselective oxidations still represent a challenge for chemists. Lyophilized cells of Janibacter terrae were employed for the chemoselective oxidation of primary alcs. to the corresponding aldehydes by hydrogen transfer with the use of acetaldehyde as the hydrogen acceptor. Secondary alc. moieties were transformed at a much slower rate. The substrate spectrum encompasses substituted benzyl alcs., whereby substrates with a substituent in the meta position were well tolerated, whereas only very small substituents were tolerated in the ortho position. Furthermore, n-alkanols and allylic alcs. were transformed with good conversions. The biocatalyst was compatible with DMSO as a water miscible organic solvent up to 30 % volume/volume

Bebell, Lisa M.; Parks, Kalynn; Le, Mylinh H.; Ngonzi, Joseph; Adong, Julian; Boatin, Adeline A.; Bassett, Ingrid V.; Siedner, Mark J.; Gernand, Alison D.; Roberts, Drucilla J. published the artcile< Placental decidual arteriopathy and vascular endothelial growth factor A expression among women with or without human immunodeficiency virus>, Reference of 112-63-0, the main research area is placental decidual arteriopathy HIV infection VEGFA; Africa; Malperfusion; histology; immunohistochemistry; intra-uterine growth restriction; pathology; pregnancy; pregnant; resource-limited; small for gestational age.

Women with human immunodeficiency virus (HIV) (WHIV) are at higher risk of adverse birth outcomes. Proposed mechanisms for the increased risk include placental arteriopathy (vasculopathy) and maternal vascular malperfusion (MVM) due to antiretroviral therapy and medical comorbid conditions. However, these features and their underlying pathophysiol. mechanisms have not been well characterized in WHIV. We performed gross and histol. examination and immunohistochem. staining for vascular endothelial growth factor A (VEGF-A), a key angiogenic factor, on placentas from women with ≥1 MVM risk factors including: weight below the fifth percentile, histol. infarct or distal villous hypoplasia, nevirapine-based antiretroviral therapy, hypertension, and preeclampsia/eclampsia during pregnancy. We compared pathol. characteristics by maternal HIV serostatus. Twenty-seven of 41 (placentas 66%) assessed for VEGF-A were from WHIV. Mean maternal age was 27 years. Among WHIV, median CD4 T-cell count was 440/μL, and the HIV viral load was undetectable in 74%. Of VEGF-A-stained placentas, both decidua and villous endothelium tissue layers were present in 36 (88%). VEGF-A was detected in 31 of 36 (86%) with decidua present, and 39 of 40 (98%) with villous endothelium present. There were no differences in VEGF-A presence in any tissue type by maternal HIV serostatus (P = .28 to >.99). MVM was more common in placentas selected for VEGF-A staining (51 vs 8%; P < .001). VEGF-A immunostaining was highly prevalent, and staining patterns did not differ by maternal HIV serostatus among those with MVM risk factors, indicating that the role of VEGF-A in placental vasculopathy may not differ by maternal HIV serostatus.

While several therapeutic options exist, the need for more effective, safe, and convenient treatment for a variety of autoimmune diseases persists. Targeting the Janus tyrosine kinases (JAKs), which play essential roles in cell signaling responses and can contribute to aberrant immune function associated with disease, has emerged as a novel and attractive approach for the development of new autoimmune disease therapies. We screened our compound library against JAK3, a key signaling kinase in immune cells, and identified multiple scaffolds showing good inhibitory activity for this kinase. A particular scaffold of interest, the 1H-pyrrolo[2,3-b]pyridine series (7-azaindoles), was selected for further optimization in part on the basis of binding affinity (Ki) as well as on the basis of cellular potency. Optimization of this chem. series led to the identification of VX-509 (decernotinib), a novel, potent, and selective JAK3 inhibitor, which demonstrates good efficacy in vivo in the rat host vs. graft model (HvG). On the basis of these findings, it appears that VX-509 offers potential for the treatment of a variety of autoimmune diseases.

De Giorgio, Francesca; Gaboardi, Mattia; Gigli, Lara; Brutti, Sergio; Arbizzani, Catia published the artcile< Deciphering the Interplay between Binders and Electrolytes on the Performance of Li4Ti5O12 Electrodes for Li-Ion Batteries>, Computed Properties of 112-63-0, the main research area is binder electrolyte lithium titanium oxide electrode battery.

Lithium titanium oxide (Li4Ti5O12, LTO) is an attractive neg. electrode for the development of safe-next-generation-lithium-ion batteries (LIBs). LTO can find specific applications complementary to existing alternatives for LIBs thanks to its good rate capability at high C-rates, fast lithium intercalation, and high cycling stability. Furthermore, LIBs featuring LTO electrodes are inherently safer owing to the LTO’s operating potential of 1.55 V vs. Li+/Li where the commonly used organic-based electrolytes are thermodynamically stable. Herein, we report the combined use of water-soluble sodium alginate (SA) binder and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI)-tetraglyme (1m-T) electrolyte and we demonstrate the improvement of the electrochem. performance of LTO-based electrodes with respect to those operating in conventional electrolyte 1M LiPF6-ethylene carbonate: di-Me carbonate (LP30). We also tackle the anal. of the impact of combining the binder/electrolyte on the long-term cycling performance of LTO electrodes featuring SA or conventional polyvinylidene fluoride (PVdF) as binders. Therefore, to assess the impact of the combination of binder/electrolyte on performance, we performed post-mortem characterization by ex situ synchrotron diffraction experiments of LTO electrodes after cycling in LP30 and 1m-T electrolytes.

Konishi, Teruko; Ishii, Tadashi published the artcile< The origin and functions of arabinofuranosyl residues in plant cell walls>, HPLC of Formula: 112-63-0, the main research area is review arabinofuranosyl residue plant cell wall.

A review. L-Arabinofuranosyl (Araf) residues are a quantifiably important constituent of plant cell walls. The results of earlier studies have led to the hypothesis that UDP-L-arabinopyranose (UDP-Arap) is the sugar donor and that the conversion to Araf occurs during the glycosyl transfer reaction. However, this mechanism is unlikely because UDP-L-arabinofuranose (UDP-Araf) has been shown to be the sugar donor in the conversion of Araf-containing oligosaccharides in plant extracts We speculated that UDP-Arap reacts with a mutase to form UDP-Araf and identified and partially characterized a rice UDP-L-arabinopyranose mutase (UAM) that catalyzes the interconversion of UDP-Arap and UDP-Araf. To investigate the effects of depleting Araf residues on cell wall structure and on rice growth and development, we used RNAi to suppress UAM expression in rice plants. Several transgenic plants had reduced proportions of Araf in their cell walls together with a decrease in the extent of substitution of the xylan backbone and a reduction of between 25% and 80% in ferulic acid and p-coumaric acid content. Transgenic plants with over 25% reduction in Araf residues were dwarfed and infertile. These results suggested that Araf residues are required for normal plant growth, development, and reproduction

Liu, Yanlin; Yu, Zhen; Wang, Binbo; Xu, Xiwei; Feng, Hongzhi; Li, Pengyun; Zhu, Jin; Ma, Songqi published the artcile< High-performance epoxy covalent adaptable networks enabled by alicyclic anhydride monoesters>, Quality Control of 112-63-0, the main research area is covalent adaptable epoxy network alicyclic anhydride monoester curing.

Transesterification-based covalent adaptable networks (CANs) exhibit malleability and reprocessability, yet are highly dependent on the addition of a large amount of catalysts to accelerate transesterification reactions. A strategy of dynamic transfer auto-catalysis has been proposed by pending dynamically transferable anhydride monoesters at the network, which will greatly enhance the auto-catalytic efficiency. Here two trifunctional acids from alicyclic five-membered cyclic anhydride and six-membered cyclic anhydride, were synthesized and cured with bisphenol A epoxy monomer, resp. The reprocessability, degradability and mech. properties of the obtained epoxy CANs can be readily tuned by changing the structure of the trifunctional acid. The conformational transition of the non-planar ring accelerated network rearrangement and the large steric hindrance slowed down the degradation rate and the rigid feature endowed high thermal and mech. properties of the epoxy CANs. In addition, the kinetically slow formation of six-membered cyclic anhydride than that of five-membered cyclic anhydride, led to the lower dynamic transfer auto-catalytic efficiency of its monoester. However, its good solubility in water gave it a fast degradation rate.

Presented is the application of a novel “”zeolite catalyst-solvent”” system for the sustainable one-step synthesis of the terpenoid manoyl oxide I, the potential precursor of forskolin and Ambrox. Manoyl oxide high-yield and large-scale production over a zeolite catalyst has been infeasible so far, while the proposed system results in 90% yields at 135°C and atm. pressure. A substrate-controlled methodol. is used to achieve selectivity. Solvent-driven catalysis was demonstrated, as the activation energy barrier decreases in the presence of appropriate solvents, being 62.7 and 93.46 kJmol-1 for a glyme-type solvent and dodecane, resp. Finally, catalyst acidity was found to be a key parameter for the process.

Despite intensive therapy, children with high-risk neuroblastoma are at risk of treatment failure. We applied a multiomic system approach to evaluate metabolic vulnerabilities in human neuroblastoma. We combined metabolomics, CRISPR screening, and transcriptomic data across more than 700 solid tumor cell lines and identified dihydroorotate dehydrogenase (DHODH), a critical enzyme in pyrimidine synthesis, as a potential treatment target. Of note, DHODH inhibition is currently under clinical investigation in patients with hematologic malignancies. In neuroblastoma, DHODH expression was identified as an independent risk factor for aggressive disease, and high DHODH levels correlated to worse overall and event-free survival. A subset of tumors with the highest DHODH expression was associated with a dismal prognosis, with a 5-year survival of less than 10%. In xenograft and transgenic neuroblastoma mouse models treated with the DHODH inhibitor brequinar, tumor growth was dramatically reduced, and survival was extended. Furthermore, brequinar treatment was shown to reduce the expression of MYC targets in 3 neuroblastoma models in vivo. A combination of brequinar and temozolomide was curative in the majority of transgenic TH-MYCN neuroblastoma mice, indicating a highly active clinical combination therapy. Overall, DHODH inhibition combined with temozolomide has therapeutic potential in neuroblastoma, and we propose this combination for clinical testing.
