The widespread emergence of  Plasmodium falciparum  ( Pf ) strains resistant to frontline agents has fuelled the search for fast-acting agents with novel mechanism of action. Here, we report the discovery and optimization of novel antimalarial compounds, the triaminopyrimidines (TAPs), which emerged from a phenotypic screen against the blood stages of  Pf . The clinical candidate (compound  12 ) is efficacious in a mouse model of  Pf  malaria with an ED 99  <30 mg kg −1  and displays good  in vivo  safety margins in guinea pigs and rats. With a predicted half-life of 36 h in humans, a single dose of 260 mg might be sufficient to maintain therapeutic blood concentration for 4–5 days. Whole-genome sequencing of resistant mutants implicates the vacuolar ATP synthase as a genetic determinant of resistance to TAPs. Our studies highlight the potential of TAPs for single-dose treatment of  Pf  malaria in combination with other agents in clinical development.
