Overview

Uncovers a potent acridone antimalarial that targets all Plasmodium stages, suggesting new treatment avenues.

Key Points

  • To evaluate the efficacy and safety of the acridone T111 against all life stages of Plasmodium.
  • In vitro testing against cultured parasites
  • Ex vivo testing against clinical isolates
  • Single-dose oral cure in a rodent model
  • Toxicology evaluations in rats
  • Resistance mechanism analysis in selected parasites
  • T111 exhibited potent activity against blood, liver, and mosquito stages
  • Effective single-dose cure in rodent models
  • Demonstrated synergy with tafenoquine
  • Safety profile shows low toxicity rates
  • Mechanism distinct from existing antimalarials targeting mitochondrial pathways
