Abstract

Premarineosin A undergoes rapid, chemoselective C12 halogenation under mild conditions, providing brominated, chlorinated, fluorinated, and iodinated analogs. These derivatives retained potent antiplasmodial activity against both chloroquine-sensitive and -resistant Plasmodium falciparum strains and displayed smaller reductions in potency against the resistant strain than the parent compound.
