title: Novel bisquinoline antimalarials. Synthesis, antimalarial activity, and inhibition of haem polymerisation.
abstract: We report the synthesis of two series of novel bisquinoline compounds that inhibit the growth of both chloroquine-sensitive and chloroquine-resistant strains of Plasmodium falciparum. To study the molecular basis of the action of these novel antimalarial drugs, we examined their ability to inhibit haem polymerisation in the presence and absence of parasite extracts. The level of antimalarial potency was correlated with the level of inhibition of haem polymerisation, suggesting that these bisquinolines exert their antimalarial activity by antagonising the sequestration of toxic haem moieties.
