Growth inhibition of parasites was evaluated by a [3H] thymidine uptake assay. Epimastigotes of (A) RA and (B) K98 strain, were adjust at 1.5×106/ml and cultured for 72 h at 28°C in the presence of the compounds at a final concentration ranging from 100 - 1 µg/ml. The percentage of inhibition was calculated as 100−[(cpm of treated parasites)/(cpm of untreated parasites)]×100. Values represent mean ± SEM from three independent experiments carried out in triplicate.
