The stability of the complexes has been investigated in DMSO. Complexes have been assessed for their cytotoxic activity against 518A2, 8505C, A253, MCF-7 and SW480 cell lines. Generally, complexes exhibited activity in the lower micromolar range; moreover, they are found to be more active than cisplatin. For the most active ruthenium(II) complex, 4b, bearing mesitylene as ligand, the mechanism of action against 8505C cisplatin resistant cell line was determined. Complex 4b induced apoptosis accompanied by caspase activation.

AB  - Neutral iridium(III) complexes of the type [Ir(eta(5)-C5Me5)Cl-2{Ph2PCH2S(O)(x)Ph-kappa P}] (1-3) with diphenylphosphino-functionalized methyl phenyl sulfides, sulfoxides, and sulfones Ph2PCH2S(O)(x)Ph (x = 0, L1; 1, 12; 2, L3) and the cationic complex [Ir(eta(5)-C5Me5)Cl(Ph2PCH2SPh-kappa P,kappa S}][PF6] (4) were synthesized and fully characterized analytically and spectroscopically. Furthermore, the structure of 2 was determined by X-ray diffraction analysis. The biological potential of the neutral and cationic iridium(III) complexes was tested in vitro against the cell lines 8505C, A253, MCF-7, SW480 and 518A2. Complex [Ir(eta(5)-C5Me5)Cl-2{Ph2PCH2S(O)Ph-kappa P}] (2), with ligand L2 kappa P coordinated containing a pendent sulfinyl group, is the most active one (IC50 values of about 3 mu M), thus, with activities comparable to cisplatin. Complex 2 proved to have an even a higher antiproliferative activity than cisplatin against 8505C and SW480 cell lines, used as a model system of highly anaplastic cancers with low sensitivity to conventional chemotherapeutics such as cisplatin. Additional experiments demonstrated that apoptosis and autophagic cell death contribute to the drug's tumoricidal action. (C) 2013 Elsevier Masson SAS. All rights reserved.
