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
摘要:
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 Ru-II(arene)X complexes (X = Cl, Br, I) linked by pyridinone-based spacers were synthesized and assayed for their in vitro antineoplastic effect. The SARs were established in terms of the arene ligand. the leaving group (the halide ligand), and the nature and number of the metal centers. It was demonstrated that, besides the previously shown effect or the spacer length, the nature of the metal center has the biggest influence on the in vitro anticancer activity. The halide ligand had no effect on the cytotoxicity, due to rapid formation of the same aquation product for all evaluated compounds. Furthermore, nearly identical activity was observed when varying the arene ligand from p-cymene to biphenyl. However, the number of metal centers was found to be important, with the dinuclear compound being more active than the analogous mono- and trinuclear species.

Multinuclear platinumanticancer 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)alkane ligand linker. A pronounced influence of the spacer length on the in vitro anticancer activity was found, which is correlated to the lipophilicity

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 0.29 mu 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-bischlorido[3-(oxo-kappa O)-2-methyl-4-pyridinonato-kappa O4](eta(6)-p-isopropyltoluene)ruthenium}dodecane, is at least 2-3 orders of magnitude more active than the mononuclear analogue chlorido[3-(oxo-kappa O)-2-methyl-4-pyronato-kappa O4](eta(6)-p-isopropyltoluene)-ruthenium.
