Development of Next-Generation Antimalarial Acridones with Radical Cure Potential.

ABSTRACT: Building from our previous lead compound T111 (1) possessing activity against both Plasmodium falciparum asexual blood-stage (ABS) and Plasmodium berghei liver-stage (LS) parasites, next-generation antimalarial acridones were systematically designed and synthesized. A large number of newly generated acridones displayed excellent antimalarial activities against both ABS and LS parasites, with feasible safety and metabolic profiles. In a high-throughput hypnozoitocidal assay using Plasmodium cynomolgi, a number of these acridones significantly inhibited schizont and hypnozoite formation in both prophylactic and radical cure-dosing modes. Notably, newer generation acridones substantially mitigated cross-resistance with atovaquone. Representative compound 28
