Exploring metallodrug-protein interactions by mass spectrometry: comparisons between platinum coordination complexes and an organometallic ruthenium compound

Paul Joseph Dyson, Angela Casini

Electrospray ionisation mass spectrometry was used to analyze the reactions of metal compds. with mixts. of selected proteins. Three representative medicinally relevant compds., cisplatin, transplatin and the organometallic ruthenium compd. RAPTA-C, were r ...

New Ruthenium Sensitizer with Carbazole Antennas for Efficient and Stable Thin-Film Dye-Sensitized Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Mingkui Wang, Jun Li, Nuttapol Pootrakulchote

A new heteroleptic ruthenium complex, coded CYC-B13, incorporating an antenna ligand composed of the sequential connection of a Conjugated segment and carbazole hole-transport moiety was prepared. This new sensitizer exhibits the lower energy MLCT band cen ...

The effect of UV-irradiation (under short-circuit condition) on dye-sensitized solar cells sensitized with a Ru-complex dye functionalized with a (diphenylamino)styryl-thiophen group

Ulf Anders Hagfeldt, Kazuteru Nonomura, Rong Zhang

A new Ru complex, cis-di(thiocyanato)(2,2'-bipyridine-4,4'-dicarboxylic acid)(4,4'-bis(2-(5-(2-(4-diphenylaminophenyl) ethenyl)-thiophen-2-yl)ethenyl)-2,2'-bipyridine)ruthenium(II) (named E322) was synthesized for use in dye-sensitized solar cells (DSCs). ...

Water-soluble arene ruthenium complexes containing pyridinethiolato ligands: Synthesis, molecular structure, redox properties and anticancer activity of the cations [(η6-arene)Ru(p-SC5H4NH)3]2+

Paul Joseph Dyson, Anna Katherine Renfrew

The cationic complexes [(η6-arene)Ru(SC5H4NH)3]2+, arene being C6H6 (1), MeC6H5 (2), p-iPrC6H4Me (3) or C6Me6 (4), have been synthesized from the reaction of 4-pyridinethiol with the corresponding precursor (η6-arene)2Ru2(μ2-Cl)2Cl2 and isolated as the chl ...

A viable hydrogen-storage system based on selective formic acid decomposition with a ruthenium catalyst

Paul Joseph Dyson, Gabor Laurenczy, Céline Fellay

The use of formic acid as a hydrogen-storage material has become more feasible thanks to the development of a homogeneous catalytic system of ruthenium water-soluble complexes (Ru/TPPTS; TPPTS=meta-trisulfonated triphenylphosphine) that selectively decompo ...

Phosphite-derivatized ruthenium-carbohydrate complexes in the catalytic hydration of nitriles

Christian Hartinger, Alexey Nazarov

The synthesis of metal complexes with bioligands is one option to introduce chirally defined ligands to catalysts. Herein, file hydration of nitriles to the corresponding carboxamides by use of ruthenium(H) complexes is described, which were obtained by at ...

Spontaneous $ Na ^{ + } $ Transients in Individual Mitochondria of Intact Astrocytes

Michaël Unser, Dimitri Nestor Alice Van De Ville, Jean-Yves Chatton

Mitochondria in intact cells maintain low

Capillary electrophoresis hyphenated to inductively coupled plasma-mass spectrometry: A novel approach for the analysis of anticancer metallodrugs in human serum and plasma

Christian Hartinger, Michael Groessl

The development of metal-based chemotherapeutics lacks methods which are capable of providing early indication on the potential of new metal complexes as future anticancer drugs. Since most of these compounds are administered intravenously, serum proteins ...

Direct observation of reaction intermediates for a well defined heterogeneous alkene metathesis catalyst

Frédéric Blanc, David Lyndon Emsley, Rajkumar Singh

Grafting of [W( NAr)(=CHtBu)(2,5-Me2NC4H2)(2)] on a silica partially clehydroxylated at 700 degrees C (SiO2-(700)) generates the corresponding monosiloxy complex [( SiO)W( NAr)(=CHtBu)(2,5-Me2NC4H2)] as the major species (approximate to 90%) along with [( ...
