Ruthenium versus platinum: interactions of anticancer metallodrugs with duplex oligonucleotides characterised by electrospray ionisation mass spectrometry

Paul Joseph Dyson, Yury Tsybin, Christian Hartinger, Michael Groessl

The binding of the ruthenium-based anticancer drug candidates KP1019, NAMI-A and RAPTA-T towards different double-stranded oligonucleotides was probed by electrospray ionisation mass spectrometry and compared with that of the widely used platinum-based che ...

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

Kay Severin, Christian Hartinger, 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 ...

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 ...
