Conjugation of organoruthenium(II) 3-(1H-benzimidzol-2-yl)-pyrazolo[3,4-b]pyridines and indolo-[3,2-d]benzazepines to recombinant human serum albumin: a strategy to enhance cytotoxicity in cancer cells

Paul Joseph Dyson, Angela Casini, Fabio Edafe

Following our strategy of coupling cyclin-dependent kinase (Cdk) inhibitors with organometallic moieties to improve their physicochemical properties and bioavailability, five organoruthenium complexes (1c-5c) of the general formula [RuCl(eta(6)-arene)(L)]C ...

Improved viability of freeze-thawed embryonic stem cells after exposure to glutathione

Adding a potent antioxidant, glutathione (GSH), to a cryoprotective solution consisting of dimethyl sulfoxide and ethylene glycol and/or postthaw culture medium significantly improved the postthaw viability of mouse embryonic stem cells. This effect, which ...

Electrodeposition and Characterization of Bismuth Telluride Nanowires

Simon Granville

In this work, we report thermoelectric measurements on electroplated bismuth telluride nanowires. Porous polycarbonate membranes, obtained by ion-track irradiation lithography, were chosen as electroplating templates. Bismuth telluride nanowires were achie ...

Homo- and Heterodinuclear Helicates of Lanthanide(III), Zinc(II) and Aluminium(III) Based on 8-Hydroxyquinoline Ligands

Jean-Claude Bünzli, Frédéric Gumy

Homonuclear helicates with rare-earth-metal(III) ions or heteronuclear derivatives with rare-earth-metal and aluminium or zinc centres are obtained in alkali-metal-templated selfassembly processes from isobutenylidene- bridged homoditopic bis(2-carb-Gamido ...

New developments in iron-catalyzed carbon-carbon bond forming reactions

The goal of this thesis is to develop new carbon-carbon bond forming reactions using inexpensive and simple coupling partners like aryl halides (pseudohalides), sulfonyl derivatives, Grignard reagents, alkenes and alkynes with metal catalysis, preferably u ...

Multifaceted Chemistry of [(Cymene)RuCl2]2 and PCy3

Rosario Scopelliti, Kay Severin, Euro Solari, Sébastien Gauthier

The reaction of (cymene)RuCl2 (1) with PCY3 was investigated using different stoichiometries and reaction conditions. Whereas a mixture of complex 1 and 2 equiv of PCy3 in methanol gave the known adduct [(cymene)Rucl(2)(PCy3)] (3) along with the phosp ...

Iron-Catalyzed Mizoroki–Heck Cross-Coupling Reaction with Styrenes

Pierre Vogel

In the presence of iron(II) chloride (FeCl2 ; 20 mol%) and potassium tert-butoxide (t- BuOK; 4 equiv.) in dimethyl sulfoxide (DMSO), aryl and heteroaryl iodides undergo stereoselective Mizoroki–Heck C—C cross-coupling reactions with styrenes at 60 8C givin ...

Relative carbanion basicities as driving force for an intramolecular silyl migration of lithiated biphenyls

Rosario Scopelliti

A solvent-dependent silyl migration of lithiated biphenyls is described, involving the intermediate formation of a pentacoordinated silicate complex. Differences in the relative basicities of the aryllithium intermediates are the possible driving force for ...

A Spirocyclic P-S Cage Cation: Synthesis and Formation of P7S6I2+

Upon ionization of the P4S3I2 molecule with Ag[Al(OR)4], a highly reactive sulfonium cation P4S3I+ is generated (NMR simulated and assigned). At -80 °C this cation reacts with additional P4S3I2 to give either an iodophosphonium P4S3I3+ cation (NMR simulate ...
