A series of 4-anilinoquinolines bearing an amino side chain linked to the aromatic ring with a carbamate or an amide bond were synthesized and evaluated for their antimalarial activity and their cytotoxicity upon MRC-5 cells. Among the 17 compounds, a majority was found to be active in the low nanomolar range against both chloroquine-sensitive and -resistant strains of Plasmodium falciparum in vitro
