Influence of the Arene Ligand, the Number and Type of Metal Centers, and the Leaving Group on the in Vitro Antitumor Activity of Polynuclear Organometallic Compounds

Kay Severin, Christian Hartinger, Alexey Nazarov

Dinuclear ruthenium complexes were shown to exhibit strong antiproliferative properties in human tumor cell lines. In order to extend the structure−activity relationships (SARs), a series of new RuII(arene)X complexes (X = Cl, Br, I) linked by pyridinone-b ...

The interplay between the VEGF-C/VEGFR-3 axis and CCL21/CCR7 axis in tumor cell invasion

Amine Issa

There are two main routes for tumor spread and metastasis, the blood vasculature and the lymphatic system. A wide range of human carcinomas, including lung, colon and breast cancer, spread to distant sites via the lymphatic system. Preclinical and clinical ...

Transferring the Concept of Multinuclearity to Ruthenium Complexes for Improvement of Anticancer Activity

Kay Severin, Alexey Nazarov, Michael Groessl

Multinuclear platinum anticancer complexes are a proven option to overcome resistance of established anticancer compounds. Transferring this concept to ruthenium complexes led to the synthesis of dinuclear Ru(II)-arene compounds containing a bis(pyridinone ...

Molecular wiring of LiMnPO4 (olivine) by ruthenium(II)-bipyridine complexes

Michael Graetzel, Shaik Mohammed Zakeeruddin, Ladislav Kavan

LiMnPO4 (olivine) was surface-modified by two different complexes: Ru-bis(4,4'-diethoxycarbonyl-2,2'-bipyridine)(4,4'-dicarboxylate-2,2'-bipyridine) and Ru-bis(4-carboxylic acid-4'-carboxylate-2,2'-bipyridine)(4,4'-dinonyl-2,2'bipyridine). These complexes ...

Femtosecond XANES Study of the Light-Induced Spin Crossover Dynamics in an Iron(II) Complex

Majed Chergui, Paul Beaud, Wojciech Gawelda, Camelia Borca, Van Thai Pham, Renske Marjan van der Veen

X-ray absorption spectroscopy is a powerful probe of mol. structure, but it has previously been too slow to track the earliest dynamics after photoexcitation. We investigated the ultrafast formation of the lowest quintet state of aq. iron(II) tris(bipyridi ...
