A series of 5-aryl-2-amino-midazohiaiazole (ITD) derivatives were identified by a phenotype-based high-throughput screening using a blood stage () growth inhibition assay. A lead optimization program focused on improving antiplasmodium potency, selectivity against human kinases, and absorption, distribution, metabolism, excretion, and toxicity properties and extended pharmacological profiles culminated in the identification of (), which demonstrates potent cellular activity against 3D7 (EC = 0.006 μM) and achieves "artemisinin-like" kill kinetics with a parasite clearance time of <24 h.
