A. CHO, B. B16F0 and C. COLO16 cells. Cell cultures (1×105) were incubated for 4 h, 8 h, 16 h, 24 h, 48 h and 72 h with (50 ng/ml, 100 ng/ml, 200 ng/ml, 400 ng/ml and 800 ng/ml) of RRM-MV and 400 ng/ml of RRM-C. A blank (no treatment control) and a positive control (treated with 60% DMSO) were included in all assays. OD was measured at 570 nm after addition of the Prestoblue™ reagent and incubation for 30 min. Cell viability was calculated and is shown relative to that of untreated (blank) sample (set to 100%). Each bar represents mean ± standard errors of 3 separate experiments in triplicate. Data values that are significantly altered (ANOVA and Dunnett's post hoc analysis) when compared to the untreated cells are indicated by the star symbol (p<0.05).
