title: Elucidation of the interactions of an anticancer ruthenium complex in clinical trials with biomolecules utilizing capillary electrophoresis hyphenated to inductively coupled plasma-mass spectrometry. Short communication.
abstract: The application of capillary electrophoresis (CE) combined with highly sensitive inductively-coupled-plasma mass spectrometric (ICP-MS) detection allows the interactions of metal complexes with biomolecules to be characterized. This technique has been used to provide new insights into the mode of action of the ruthenium-based anticancer drug candidate indazolium [trans-tetrachlorobis(1H-indazole)ruthenate(III)] (KP1019). While the compound binds rapidly and efficiently to serum proteins, especially albumin, its reactivity towards the model DNA compound 2'-deoxyguanosine 5'-monophosphate (5'-dGMP) is moderate.
