The three synthesized trinitro tribenzylamine derivatives were tested in vitro against Plasmodium falciparum isolates (3D7 strain) using parasite lactate dehydrogenase assay (pLDH). The result showed significant activity with IC50 ranging from 18 to 30 nM. The meta derivative (IC50:18.823 nM) showed better antiplasmodial activity than ortho (IC50: 30.287 nM) and para (IC50: 22.297 nM) derivatives, and even chloroquine phosphate (IC50: 22.777 nM).</span></p>
