Kumar, Deepak; Singh, Hema; Maurya, Mehilal; Nguyen, Van-Huy; Vo, Dai-Viet N.; Sharma, Ajit; Banerjee, Shaibal published the artcile< Novel evaluation enhancement role of poly (1-(3-nitrophenyl)-1H-1,2,3-triazol-4-yl) acrylate materials for propellant composite formulation>, Computed Properties of 112-63-0, the main research area is propellant composite nitrophenyl triazolyl acrylate enhancement.

The performance of solid propellants is often tailored by incorporating energetic materials such as novel oxidizers, energetic binders, and ballistic modifiers. Metal oxide nanoparticles are known for their persuasive nature to modify burning rate of ammonium perchlorate based composite propellants. In the present work, nano iron oxide and poly (1-(3-nitrophenyl)-1H-1,2,3-triazol-4-yl) acrylate are incorporated in the composite propellant formulation by partly replacing coarse ammonium perchlorate (AP) as well as hydroxy terminated polybutadiene (HTPB), resp., and different properties were evaluated. The mech. properties data revealed that on increasing the percentage of polymer in the composition by partly replacing HTPB, there is an increase in tensile strength while decreasing elongation percentage. The data of ballistic properties revealed that on incorporation of nano iron oxide in the composition enhances the burning rate while on partial replacement of HTPB with polymer there is a decrease in burning rate from 11.95 mm s-1 to 8.75 mm s-1, resp. was observed

Sun, Rui; Lei, Chao; Chen, Liang; He, Liqing; Guo, Haixun; Zhang, Xiang; Feng, Wenke; Yan, Jun; McClain, Craig J.; Deng, Zhongbin published the artcile< Alcohol-driven metabolic reprogramming promotes development of RORγt-deficient thymic lymphoma>, Computed Properties of 112-63-0, the main research area is thymic lymphoma RORgammat alc metabolism.

RORγt is a master regulator of Th17 cells. Despite evidence linking RORγt deficiency/inhibition with metastatic thymic T cell lymphomas, the role of RORγt in lymphoma metabolism is unknown. Chronic alc. consumption plays a causal role in many human cancers. The risk of T cell lymphoma remains unclear in humans with alc. use disorders (AUD) after chronic RORγt inhibition. Here we demonstrated that alc. consumption accelerates RORγt deficiency-induced lymphomagenesis. Loss of RORγt signaling in the thymus promotes aerobic glycolysis and glutaminolysis and increases allocation of glutamine carbon into lipids. Importantly, alc. consumption results in a shift from aerobic glycolysis to glutaminolysis. Both RORγt deficiency- and alc.-induced metabolic alterations are mediated by c-Myc, as silencing of c-Myc decreases the effects of alc. consumption and RORγt deficiency on glutaminolysis, biosynthesis, and tumor growth in vivo. The ethanol-mediated c-Myc activation coupled with increased glutaminolysis underscore the critical role of RORγt-Myc signaling and translation in lymphoma.

Rogers, Gary A.; Parsons, Stanley M.; Anderson, D. C.; Nilsson, Lena M.; Bahr, Ben A.; Kornreich, Wayne D.; Kaufman, Rose; Jacobs, Robert S.; Kirtman, Bernard published the artcile< Synthesis, in vitro acetylcholine-storage-blocking activities, and biological properties of derivatives and analogs of trans-2-(4-phenylpiperidino)cyclohexanol (vesamicol)>, Electric Literature of 112-63-0, the main research area is vesamicol analog preparation acetylcholine blocking; phenylpiperidinocychlohexanol analog preparation; piperidinocyclohexanol; structure activity vesamicol analog acetylcholine blocking.

Eighty-four analogs, e.g., I [R = (un)substituted Ph, cyclohexyl, PhCH2, Ph(CH2)3] and derivatives of the acetylcholine storage-blocking drug trans-2-4(4-phenylpiperidino)cyclohexanol (vesamicol) were synthesized, and their potencies were evaluated with the acetylcholine active-transport assay utilizing purified synaptic vesicles from Torpedo elec. organ. The parent drug exhibits enantioselectivity, with (-)-vesamicol being 25-fold more potent than (+)-vesamicol. The mol. structure and absolute configuration of (+)-vesamicol were determined by x-ray crystallog. The absolute configuration of (-)-vesamicol is (1R,2R). Structure-activity evidence indicates that (-)-vesamicol does not act as an acetylcholine analog. Alterations to all three rings can have large effects on potency. Unexpectedly, analogs locking the alc. and ammonium groups trans-diequatorial or trans-diaxial both exhibit good potency. A potent benzovesamicol family was discovered that is suitable for facile elaboration of the sort useful in affinity labeling and affinity chromatog. applications. A good correlation was found between potencies as assessed by the acetylcholine transport assay and LD50 values in mouse.

Parzuchowski, Pawel G.; Swiderska, Aleksandra; Roguszewska, Marlena; Rolinska, Karolina; Wolosz, Dominik; Maminski, Mariusz published the artcile< Hyperbranched poly(ether-siloxane)s containing ammonium groups: Synthesis, characterization and catalytic activity>, Reference of 112-63-0, the main research area is trimethylammonium polyether siloxane hyperbranched polymer anionic ring opening copolymerization; carbon dioxide oxirane ethylene carbonate cycloaddition catalyst; carbon dioxide; catalysis; cycloaddition; ethylene carbonate; hyperbranched polymer; oxirane; polyglycidol; polysiloxane.

In this article we report an easy synthetic route towards hyperbranched polyglycerols (Amm-HBPGs) containing trimethylammonium groups and siloxane or hydroxyl end-groups. Siloxane derivatives of Amm-HBPGs were synthesized in an efficient five-step procedure including an anionic ring opening copolymerization of the phthalimide-epoxy monomer with glycidol, followed by reactions with allyl bromide, hydrosilylation with hydrogenheptamethyltrisiloxane, hydrazinolysis of phthalimide groups and quaternization of resulting amine groups with Me iodide. Hydroxyl derivatives were obtained by quaternization of previously reported aminated HBPG’s with Me iodide. Polymeric products were characterized using various NMR techniques, FTIR, and elemental anal. Both Amm-HBPGs were shown to be effective in catalysis of addition of CO2 to oxirane. The hydrophilic catalysts showed higher efficiency but synthesis of ethylene carbonate was accompanied by formation of small amounts of ethylene glycol. The siloxane-containing catalyst was easily separable from reaction mixture showing high potential in the process of converting carbon dioxide into valuable chem. raw materials.

Zheng, Leizhi; Yang, Guoqiang; Liu, Jia; Jiang, Bowen; Yu, Ting; Hu, Xingbang; Zhang, Zhibing published the artcile< Efficient chemical fixation of CO2 to form switchable ionic liquid to synthesize benzimidazolones under mild conditions>, Application of C19H34O2, the main research area is dihydrobenzimidazolone green preparation; benzene diamine carbon dioxide carbonylation catalyst diazabicyclononene.

In this work, a novel pathway to synthesize benzimidazolone derivatives I [R = 5-Me, 5-MeO, 5,6-di-Me] via the carbonylation of o-phenylenediamines with carbon dioxide under mild conditions (e.g., 50°C, 0.5 MPa) in the presence of 1,5-diazabicyclo[4.3.0]non-5-ene (DBN) was reported. In this progress, the DBN, acting as superbase, could form strong intermol. hydrogen bonds with o-phenylenediamines. The carbon dioxide was chem. fixed to form switchable ionic liquids (SILs). Then, CH2Br2 as a dehydrant easily involved parallel attack carbamates salts to form leaving group. To the best of our knowledge, this protocol provided a sustainable technique for the production of benzimidazolones under mild conditions.

Bisbach, Celia M.; Hass, Daniel T.; Thomas, Eric D.; Cherry, Timothy J.; Hurley, James B. published the artcile< Monocarboxylate transporter 1 (MCT1) mediates succinate export in the retina>, Reference of 112-63-0, the main research area is succinate monocarboxylate transporter retina.

Succinate is exported by the retina and imported by eyecup tissue. The transporters mediating this process have not yet been identified. Recent studies showed that monocarboxylate transporter 1 (MCT1) can transport succinate across plasma membranes in cardiac and skeletal muscle. Retina and retinal pigment epithelium (RPE) both express multiple MCT isoforms including MCT1. We tested the hypothesis that MCTs facilitate retinal succinate export and RPE succinate import. We assessed retinal succinate export and eyecup succinate import in short-term ex vivo culture using gas chromatog.-mass spectrometry. We tested the dependence of succinate export and import on pH, proton ionophores, conventional MCT substrates, and the MCT inhibitors AZD3965, AR-C155858, and diclofenac. Succinate exits retinal tissue through MCT1 but does not enter the RPE through MCT1 or any other MCT. Intracellular succinate levels are a contributing factor that determines if an MCT1-expressing tissue will export succinate. MCT1 facilitates export of succinate from retinas. An unidentified, non-MCT transporter facilitates import of succinate into RPE.

Zhang, Gang; Presly, Oliver; White, Fraser; Oppel, Iris M.; Mastalerz, Michael published the artcile< A Shape-Persistent Quadruply Interlocked Giant Cage Catenane with Two Distinct Pores in the Solid State>, HPLC of Formula: 112-63-0, the main research area is persistent quadruply interlocked giant cage catenane pore solid crystallog; boronic acids; catenanes; dynamic covalent chemistry; porosity; triptycene.

Discrete interlocked three-dimensional structures are synthetic targets that are sometimes difficult to obtain with classical synthetic approaches, and dynamic covalent chem. is a useful method to form such interlocked structures as thermodynamically stable products. Although interlocked and defined hollow structures are found, for example, in some viruses, similar structures have rarely been synthesized on a mol. level. Shape-persistent interlocked organic cage compounds with dimensions in the nanometer regime are now accessible in high yields during crystallization through the formation of 96 covalent bonds. The interlocked mols. form an unprecedented porous material with intrinsic and extrinsic pores both in the micropore and mesopore regime.
