Abstract

Twenty-one Alkaloids have been assessed for activities against Plasmodium falciparum (multidrug- resistant strain K1) in vitro; 18 of these are reported for the first time. Two protoberberine Alkaloids, dehydrodiscretine and berberine, were found to have antiplasmodial IC(50) values less than 1 M, while seven alkaloids-allocrytopine, columbamine, dehydroocoteine, jatrorrhizine, norcorydine, thalifendine, and ushinsunine-had values between 1 and 10 M. These results are discussed in the context of structure-activity relationships. Compounds were also assessed for antiamoebic and cytotoxic activities, but none was significantly active except for berberine, which was moderately cytotoxic.
