Fig. (7) Annexin V assay. Negative sample presented the lowest level of apoptosis induction while the highest level was observed in the positive camptothecin control. Both experimental BQ compounds presented apoptosis levels comparable to the positive control. Statistical analysis performed was a one-way ANOVA, with Tukey post hoc test, where p <0.05 was considered to be significant. (P summary;*** = p <0.0001).
