Fig. 1. In vitro screening of the activity of the selected CPP and their respective PQ-C4-CPP conjugates against liver-stage P. berghei parasites, according to a previously reported method:32 infection burden (bars) and host cell confluency (dots) are expressed as % of control. The compounds were assayed at 1, 5 and 10 μM, and PQ was included as the reference parent drug, for comparison. The graph shows representative data from 3 independent experiments, each of which employing 3 replicates for each experimental condition.
