Abstract: In vitro studies with the ruthenium(II) and analogous iridium(III) complexes [Ru(η6-
p-cymene)Cl2{Ph2PCH2CH2CH2S(O)xPh-κP}], [Ru(η6-p-cymene)Cl{Ph2PCH2CH2CH2S(O)xPh-
κP,κS}][PF6] (1–4), [Ir(η5-C5Me5)Cl2{Ph2PCH2CH2CH2S(O)xPh-κP}] and [Ir(η5-C5Me5)Cl{Ph2
PCH2CH2CH2S(O)xPh-κP,κS}][PF6] (5–8; x = 0, 1) revealed the high selectivity toward the
8505C, A253, MCF-7, SW480 and 518A2 cancer cell lines. Thus, the cationic ruthenium complex
4 proved to be the most selective one. In case of the neutral and cationic ruthenium complexes
1–4 the caspase-dependent apoptotic cell death was proven as the main cause of the drug’s
tumoricidal action on 8505C cell line.
