Structure, dynamics and catalytic activity of ruthenium(II)-arene phosphine complexes

This thesis encompasses work on the coordination chemistry and catalytic activity of half sandwich ruthenium(II)-arene phosphine complexes. The investigation of phosphine dissociation and association reactions of these complexes represents the unifying the ...

Novel strategies for overcoming drug resistance in transition metal-based anticancer compounds

Wee Han Ang

Cisplatin is one of the most important and widely used anticancer drug in clinical use. However, its effectiveness is limited by its high toxicity and incidence of drug resistance. This has provided motivation for the search for transition metal-based drug ...

Self-assembly of organometallic macrocycles and cages

Thomas Brasey

Neutral metallamacrocycles with four or ten metal centers were obtained by reaction of [(R3P)PdCl2]2 with 2,3-dihydroxypyridine and derivatives or 2-hydroxynicotinic acid in the presence of base. In all these assemblies, the two O-donor atoms of the ligand ...

New polynuclear catalysts for atom-transfer radical addition reactions

Laurent Quebatte

Homo- and heterobimetallic complexes of the late transitions metals have been synthesized by metathesis reactions of the corresponding chloro-bridged dimers. These reactions have the advantage of being fast and giving rise to structurally defined products ...

Silver Complexes of Cyclic Hexachlorotriphosphazene

The first solid-state structures of complexed P3N3X6 (X=halogen) are reported for X=Cl. The compounds were obtained from P3N3Cl6 and Ag[Al(OR)4] salts in CH2Cl2/CS2 solution. The very weakly coordinating anion with R=C(CF3)3 led to the salt Ag(P3N3Cl6)2+[A ...

Metal-based antitumour drugs in the post genomic era

Paul Joseph Dyson, Gianni Sava

The discovery of new metal-based antitumor drugs, whether cisplatin derivs. or those based on other metals, has been largely based on cell viability assays (IC50 values) and compds. that bind to DNA. This approach has been applied for more than 30 years du ...

Classical and Non-Classical Ruthenium-Based Anticancer Drugs: Towards Targeted Chemotherapy

Paul Joseph Dyson, Wee Han Ang

Ruthenium-based anticancer chemotherapies are making significant advances in clinical trials. Until recently, the focus has been on coordination complexes, and mechanisms such as "activation by reduction" and "transferrin-targeted delivery" have been propo ...

Binding of Organometallic Ruthenium(II) and Osmium(II) Complexes to an Oligonucleotide: A Combined Mass Spectrometric and Theoretical Study

Paul Joseph Dyson, Rosario Scopelliti, Ursula Röthlisberger, Ivano Tavernelli, Christian Gossens, Antoine Dorcier

Ru(II) and Os(II) p-cymene dichloride complexes with either a pta (1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane) or [pta-Me]Cl ligand which exhibit anticancer activity were prepd. and characterized by 1H and 31P NMR spectroscopy and mass spectrometry. Thr ...

Coordination chemistry of a new rigid, hexadentate bispidine-based bis(amine)tetrakis(pyridine) ligand

Gabor Laurenczy

The hexadentate bispidine-based ligand 2,4-bis(2-pyridyl)-3,7-bis(2-methylenepyridine)-3,7-diazabicyclo[3.3.1]nonane-9-on-1,5-bis(carbonic acid methyl ester), L-6m, with four pyridine and two tertiary amine donors, based on a very rigid diazaadamantane-der ...

Rational design of organo-ruthenium anticancer compounds

Ursula Röthlisberger, Ivano Tavernelli, Christian Gossens

Organometallic ruthenium(II)-arene complexes are currently attracting increasing interest as anticancer compds. with the potential to overcome drawbacks of traditional drugs like cisplatin with respect to resistance, selectivity, and toxicity. Rational des ...
