Abstract: The aim of this study was to identify new active compounds against Plasmodium falciparum based on our previous research carried out on 3-phenylquinoxaline-2- carbonitrile 1,4-di-N-oxide derivatives. Antimalarial activity was evaluated in vitro against Plasmodium falciparum (3D7 and K1 strains) by the incorporation of [ 3 H]hypoxanthine. Cytotoxicity was tested in KB cells by Alamar Blue assay. Twelve compounds were synthesized and evaluated for antimalarial activity. Eight of them showed a IC 50 < 1 µM against 3D7 strain. Derivative 1 demonstrated high potency (IC 50 = 0.63 µM) and good selectivity (SI=10.35), thereby becoming a new lead-compound.
