Effect of selected benzimidazole derivatives on ROS production. Five potent compounds were incubated with P. falciparum-infected cultures and the production of reactive oxygen species was measured through fluorometry at 0.5, 6 and 9 h after their addition at 1 µM. As positive control, a sample containing hydrogen peroxide at 200 μM was added. Samples were measured in triplicates. One-way ANOVA with Turkey´s comparison was used to measure significance with respect to the untreated control at each different time point. n = 2. (a) BZ 1, (b) BZ 5, (c) BZ 16, (d) BZ 26 and (e) BZ 33. *p < 0.05, **p < 0.01, ***p < 0.005.
