摘要: The aim of present study was to verify the in vitro antitumor activity a ruthenium complex, cis-(dichloro)tetraammineruthenium(III) chloride (cis-[RuCl2(NH3)4]Cl) toward different tumor cell lines. studies showed that ruthenium(III) complex presents relevant cytotoxic against murine B lymphoma (A-20), ascitic sarcoma 180 (S-180), human breast adenocarcinoma (SK-BR-3), and T leukemia (Jurkat) lines very low cytotoxicity peripheral blood mononuclear cells. decreased fraction cells G0/G1 and/or G2-M phases, indicating this compound may act on resting/early entering precycling high concentration (2 mg mL−1) cis-[RuCl2(NH3)4]Cl Jurkat correlated with an increased number annexin V-positive also presence DNA fragmentation, suggesting induces apoptosis development new antineoplastic medications demands adequate knowledge order avoid inefficient or toxic treatments. Thus, mechanistic understanding how metal complexes achieve their activities is crucial clinical success rational design compounds improved potency.
