FIG. 1.
Effect of the NO donors trans-[Ru(NO)(NH3)4L]3+, where L is pz, imN, isn, or py, against T. cruzi epimastigote forms (T. cruziepi) (1.0 × 106 parasites/ml) after 24 h of incubation. The concentrations range from 100 μM up to 1 mM. The data are representative of results of three independent experiments with similar results and are shown as percentages of the control results.
