Some antimalarial agents in use typically bear basic side chains as ligands. Such ligands were attached to the amino substituent of a bridgehead atom of already antiprotozoal active 3-azabicyclo[3.2.2]nonanes. Structure verification was done by NMR measurements. The new compounds were tested for their antiplasmodial and antitrypanosomal activities against Plasmodium falciparum K 1 (multiresistant) and Trypanosoma brucei rhodesiense as well as for their cytotoxicity against L6 cells. Their activities are compared to those of already prepared compounds and structure-activity relationships are discussed.
