[EN] Novel quinolyl and acridinylhydrazone compounds of formula (I), which present remarkable biological activity especially against the choloroquine-resistant Plasmodium falciparum strains, useful for the treatment and prevention of malaria infection are described herein. [FR] La présente invention concerne des quinolinyl- et des acridinyl-hydrazones de formule (I) dont l'activité biologique est remarquable, en particulier contre les souches de Plasmodium falciparum résistantes à la chloroquine, et qui peuvent être employées dans le traitement prophylactique et thérapeutique d'une infection de malaria.
Design, Synthesis, and Structure–Activity Relationship Studies of 4-Quinolinyl- and 9-Acrydinylhydrazones as Potent Antimalarial Agents
synthesis, and biological investigation of novel antimalarial agents with low potential to develop resistance and structurally based on a highly conjugated scaffold. Starting from a new hit, the designed modifications were performed hypothesizing a specific interaction with free heme and generation of radical intermediates. This approach provided antimalarials with improved potency against chloroquine-resistant
