ChemInform Abstract: Mechanosynthesis of Pharmaceutically Relevant Sulfonyl‐(thio)ureas.

23-10-2014 | Davin Tan, Vjekoslav Strukil, Cristina Mottillo, Tomislav Friscic, ChemInform, 2014

Abstract The first application of mechanochemistry to conduct the synthesis of sulfonyl‐(thio)ureas (III), (VI), and (X), including antidiabetic drugs tolbutamide, chlorpropamide (VIa) and glibenclamide (X) by either stoichiometric base‐assisted or Cu‐catalyzed coupling of sulfonamides and ...

Study on the Synergistic Properties of Quaternary Phosphonium Bromide Salts with N-Vinylcaprolactam Based Kinetic Hydrate Inhibitor Polymers

16-10-2014 | Carlos D. Magnusson; Malcolm A. Kelland, Energy & Fuels, 2014

We have evaluated the synergism of five tetraalkyl phosphonium bromide salts with N-vinylcaprolactam based polymers by carrying out high pressure rocking cell experiments with a structure II-forming natural gas mixture. (n-Pe)4PBr was shown to be a superior synergist than (n-Bu)4PBr when used in ...

Released neighboring-cation stress induced blue-shift of Eu2+ emission in (Ba,Sr)3Lu(PO4)3:Eu2+ eulytite solid-solution phosphors

08-10-2014 | Ziyuan Wang; Zhiguo Xia; Maxim Molokeev; Victor V. Atuchin; QuanLin Liu, Dalton Transactions, 2014

A series of iso-structural eulytite-type (Ba,Sr)3Lu(PO4)3:Eu2+ solid solution phosphors with different Sr/Ba ratios were synthesized by a solid-state reaction. Crystal structures of (Ba,Sr)3Lu(PO4)3:Eu2+ were resolved by Rietveld method, which shows an eulytite-type structure as cubic Bi4(SiO4)3 ...

Development of standards for reliable surface analyses by ISO technical committee 201 on surface chemical analysis

07-10-2014 | C. J. Powell, R. Shimizu, K. Yoshihara, S. Ichimura, Surface and Interface Analysis, 2014

The need for reliable surface analyses together with quality‐management requirements for analytical laboratories led the International Organization for Standardization (ISO) to form its Technical Committee (TC) 201 on Surface Chemical Analysis in 1991. This article describes the organization of ...

Molecules, Vol. 19, Pages 15611-15623: Anti-Fibrosis Effect of Scutellarin via Inhibition of Endothelial–Mesenchymal Transition on Isoprenaline-Induced Myocardial Fibrosis in Rats

29-09-2014 | Zhou, Hao ; Chen, Xiao ; Chen, Lingzhi ; Zhou, Xi ; Zheng, Gaoshu ; Zhang, Huaiqin ; Huang, Weijian ; Cai, Jiejie, Molecules, 2014

Scutellarin (SCU) is the major active component of breviscapine and has been reported to be capable of decreasing myocardial fibrosis. The aim of the present study is to investigate whether SCU treatment attenuates isoprenaline-induced myocardial fibrosis and the mechanisms of its action. Rats ...

ATP Binding and Aspartate Protonation Enhance Photoinduced Electron Transfer in Plant Cryptochrome

07-09-2014 | Fabien Cailliez; Pavel Müller; Michaël Gallois; Aurélien de la Lande, Journal of the American Chemical Society, 2014

Cryptochromes are flavoproteins encountered in most vegetal and animal species. They play a role of blue-light receptors in plants and in invertebrates. The putative resting state of the FAD cofactor in these proteins is its fully oxidized form, FADox. Upon blue-light excitation, the ...
