Then, 120 new derivatives were synthesized and evaluated in vitro; compared to drug references, 40 showed good activity toward chloroquine sensitive (IC50 35-344 nM) and resistant (IC50 45-800 nM) P. falciparum strains. They were neither cytotoxic (CC50 15-50 mu M) toward HepG2 and CHO cells, nor mutagenic. Structure activity relationships were defined. The lead-compound also appeared active against the Plasmodium liver stages (Plasmodium yoelii IC50 = 35 nM) and a preliminary in vivo evaluation indicated the in vitro activity was preserved (45% reduction in parasitemia compared to untreated infected mice). A mechanistic study demonstrated these molecules do not involve any of the pathways described for commercial drugs and exert a specific activity on the ring and trophozoite stages. 2015 Elsevier Masson SAS.
