Abstract

Water soluble dinuclear Ru-arene complexes were synthesized and found to exert promising cytotoxic effects in human cancer cells, which could be increased to an IC50 of 0.5 M by increasing the spacer length between the metal centers. Cytotoxicity could be correlated with lipophilicity (log P values) and water solubility. The most potent dinuclear compound, 1,12-bis{chlorido[3-(oxo-κO)-2-methyl-4-pyridinonato-κO4](η6-p-isopropyltoluene)ruthenium}dodecane 4c, is at least 2¿3 orders of magnitude more active than the mononuclear analogue chlorido[3-(oxo-κO)-2-methyl-4-pyronato-κO4](η6-p-isopropyltoluene)ruthenium.
