Effect of ruthenium complexes containing heterocyclic thioamidates on the morphology of HepG2 cells, as determined by light-scattering features detected by flow cytometry after 24 (A,C) and 48 (B,D) h of incubation. The negative control (CTL) was treated with the vehicle (0.2% DMSO) that was used to solubilize and dilute the complexes, and doxorubicin (DOX, 2 μM) was used as the positive control. Data are presented as the mean ± S.E.M. of three independent experiments that were performed in duplicate. *P < 0.05 compared with the negative control, as determined by ANOVA followed by the Student-Newman-Keuls test. Ten thousand events were evaluated per experiment, and cellular debris was omitted from the analysis.
