Ligand Conformation Dictates Membrane and Endosomal Trafficking of Arginine‐Glycine‐Aspartate (RGD)‐Functionalized Mesoporous Silica Nanoparticles

Published: 15 May 2012

Author(s): I‐Ju Fang, Igor I. Slowing, Kevin C.‐W. Wu, Victor S.‐Y. Lin, Brian G. Trewyn

Abstract Recent breakthrough research on mesoporous silica nanoparticle (MSN) materials has illustrated their significant potential in biological applications due to their excellent drug delivery and endocytotic behavior. We set out to determine if MSN, covalently functionalized with conformation specific bioactive molecules (either linear or cyclic RGD ligands), behave towards mammalian cells in a similar manner as the free...

Click Ionic Liquids: A Family of Promising Tunable Solvents and Application in Suzuki–Miyaura Cross‐Coupling

Published: 15 May 2012

Author(s): Liuyi Li, Jinyun Wang, Tao Wu, Ruihu Wang

Abstract A series of click ionic salts 4 a–4 n was prepared through click reaction of organic azides with alkyne‐functionalized imidazolium or 2‐methylimidazolium salts, followed by metathesis with lithium bis(trifluoromethanesulfonyl)amide or potassium hexafluorophosphate. All salts were characterized by IR, NMR, TGA, and DSC, and most of them can be classified as ionic liquids. Their steric and electronic properties can be easily...

Highly Efficient Redox Isomerisation of Allylic Alcohols Catalysed by Pyrazole Based Ruthenium(IV) Complexes in Water: Mechanisms of Bifunctional Catalysis in Water

Published: 15 May 2012

Author(s): Luca Bellarosa, Josefina Díez, José Gimeno, Agustí Lledós, Francisco J. Suárez, Gregori Ujaque, Cristian Vicent

Abstract The catalytic activity of ruthenium(IV) ([Ru(η3:η3‐C10H16)Cl2L]; C10H16=2,7‐dimethylocta‐2,6‐diene‐1,8‐diyl, L=pyrazole, 3‐methylpyrazole, 3,5‐dimethylpyrazole, 3‐methyl‐5‐phenylpyrazole, 2‐(1H‐pyrazol‐3‐yl)phenol or indazole) and ruthenium(II) complexes ([Ru(η6‐arene)Cl2(3,5‐dimethylpyrazole)]; arene=C6H6, p‐cymene or C6Me6) in the redox isomerisation of allylic alcohols into carbonyl compounds in water is reported. The former show much higher ...

Ionic‐Liquid‐Mediated Active‐Site Control of MoS ₂ for the Electrocatalytic Hydrogen Evolution Reaction

Published: 15 May 2012

Author(s): Vincent Wing‐hei Lau, Anthony F. Masters, Alan M. Bond, Thomas Maschmeyer

Abstract The layered crystal MoS2 has been proposed as an alternative to noble metals as the electrocatalyst for the hydrogen evolution reaction (HER). However, the activity of this catalyst is limited by the number of available edge sites. It was previously shown that, by using an imidazolium ionic liquid as synthesis medium, nanometre‐size crystal layers of MoS2 can be prepared which exhibit a very high number of active edge sites as well as...

Expanding the Horizon of the Thymine Isostere Biochemistry: Unique Cyclobutane Dimers Formed via Photoreaction between a Thymine and a Toluene Residue in the Dinucleotide Framework

Published: 15 May 2012

Author(s): Degang Liu, Yan Zhou, Jingzhi Pu, Lei Li

Abstract Substituted toluenyl groups are considered as close isosteres of the thymine residue. They can be recognized by DNA polymerases as if they were thymine. These toluene derivatives are generally inert toward radical additions, including the [2+2] photo‐cycloadditions, due to the stable structure of the aromatic ring and are usually used as solvents for radical reactions. Surprisingly, after incorporating toluene into the...

Decalactone Derivatives from Corynespora cassiicola , an Endophytic Fungus of the Mangrove Plant Laguncularia racemosa

Published: 14 May 2012

Author(s): Weaam Ebrahim, Amal H. Aly, Attila Mándi, Frank Totzke, Michael H. G. Kubbutat, Victor Wray, Wen‐Han Lin, Haofu Dai, Peter Proksch, Tibor Kurtán, Abdessamad Debbab

Abstract Chemical investigation of the ethyl acetate extract of Corynespora cassiicola, isolated from leaf tissues of the Chinese mangrove medicinal plant Laguncularia racemosa, yielded four new secondary metabolites, including three decalactones, xestodecalactones D–F (1–3) as well as corynesidone C (4), in addition to four known compounds. The structures of the new compounds were determined on the basis of one‐ and two‐dimensional NMR spectroscopy as...

Hybrid Cage Compounds with Organic and Inorganic Building Blocks

Published: 14 May 2012

Author(s): Andreas Kracke, Carsten von Hänisch, Nina Kramer

Abstract Two new hybrid ligands that exhibit organic as well as siloxane chains between four phosphorus atoms in bridge‐head positions were synthesized. These species show a very different ability with regard to the formation of coordination compounds. Whereas compound 1 with the short (C2H4)2O ether units shows no ability to act as a ligand, the compound with the longer (C2H4O)2C2H4 chains between the siloxane fragments could be obtained as...

Solvent‐Free Epoxidation of Olefins Catalyzed by “[MoO ₂ (SAP)]”: A New Mode of tert ‐Butylhydroperoxide Activation

Published: 13 May 2012

Author(s): Julien Morlot, Nicolas Uyttebroeck, Dominique Agustin, Rinaldo Poli

Abstract The mononuclear molybdenum complexes [MoO2(acac)2] (1, acac=acetylacetonate), [MoO2(SAP)(MeOH)] (2), and dinuclear oxomolybdic complexes [MoO2L]2 [L=salicylideneaminophenolato (SAP, 5), salicylideneaminoethanolato (SAE, 6), salicylideneaminomethylpropanolato (SAMP, 7)] have been investigated as (pre)catalysts for the epoxidation of olefins under solvent‐free conditions, using tert‐butylhydroperoxide (TBHP, 70 % in water) as an oxidant. Complexes 6 and 7,...

Electrogenerated Polymers as Efficient and Robust Heterogeneous Catalysts for the Hydrolytic Kinetic Resolution of Terminal Epoxides

Published: 13 May 2012

Author(s): Xiang Hong, Mohamed Mellah, Franck Bordier, Régis Guillot, Emmanuelle Schulz

Abstract Thiophene‐ and pyrrole‐modified chiral cobalt–salen complexes were found to be efficient, enantioselective homogeneous catalysts for the dynamic hydrolytic kinetic resolution (HKR) of epibromohydrin. Their corresponding electrogenerated thiophene–salen–cobalt polymers were prepared by anodic oxidation and could be recovered as insoluble powders for heterogeneous catalysis. Their activity and selectivity were evaluated...

The Prospect of FKBP51 as a Drug Target

Published: 13 May 2012

Author(s): Mathias V. Schmidt, Marcelo Paez‐Pereda, Florian Holsboer, Felix Hausch

Abstract The FK506 binding protein 51 (FKBP51) is best known as an Hsp90‐associated co‐chaperone that regulates the responsiveness of steroid hormone receptors. In human genetic association studies, FKBP51 has repeatedly been associated with emotion processing and numerous stress‐related affective disorders. It has also been implicated in contributing to the glucocorticoid hyposensitivity observed in New World primates. More...
