Synthesis of novel phthalimide-based piperazine conjugated analogs as anti-malarial agents

Abstract

In the present report, we synthesized twelve novel phthalimide analogs and evaluated for antiplasmodial efficacy on Plasmodium falciparum culture. Two molecules exhibited significant inhibition percentages at 1 µM concentration without any apparent cytotoxicity on HepG2 cells. Inhibitory concentration (IC50) for both the hit compounds 6d and 8a was observed in micromolar range, 1.20 µM and 1.66 µM, respectively. Extensive in silico studies conducted indicate plasmepsin IX as a possible target for inhibitory activity of the reported molecules.
