Proteomic analysis of Plasmodium falciparum response to isocryptolepine derivative.

ABSTRACT: Drug-resistant strains of malaria parasites have emerged for most of antimalarial medications. A new chemotherapeutic compound is needed for malarial therapy. Antimalarial activity against both drug-sensitive and drug-resistant P. falciparum has been reported for an isocryptolepine derivative, 8-bromo-2-fluoro-5-methyl-5H-indolo[3,2-c]quinoline (ICL-M), which also showed less toxicity to human cells. ICL-M has indoloquinoline as a core structure and its mode of action remains unclear. Here, we explored the mechanisms of ICL-M in P. falciparum by assessing the stage-specific activity, time-dependent effect, a proteomic analysis and morphology. Since human topo II activity inhibition has been reported as a function of isocryptolepine derivatives, malarial topo II activity inhibition of ICL-M
