The in vitro antimalarial screening of the new synthesized compounds 5aeg revealed good to moderate activities in nM range against both the tested Dd2 (CQ S ) and D10 strains (CQ R ) of P. Analysis of the activity of the compounds recorded in Table 1 reveals that replacing C-5 ethyl ester of the previously reported [29] decrease in antimalarial activity against both the chloroquine sensitive and chloroquine resistant strains of P. In this study, we have evaluated the mechanism of antimalarial activity of the most potent compound 5b of the series by studying its binding with heme (Fig. 4) . ./cache/cord-265764-h4zg0q8x.txt ./txt/cord-265764-h4zg0q8x.txt
