DSM265 (0.5 to 75 mg/kg; Oral administration; twice daily; for 4 days; NOD-scid IL-2Rγnull (NSG) mice) has potent in vivo antimalarial activity with 90% effective dose (ED90) of 3 mg/kg per day (1.5 mg/kg twice daily). The maximum rate of parasite killing occurred at and above a dose of 13 mg/kg per day (6.4 mg/kg twice daily). DSM265 has moderate terminal elimination half-life (t1/2) of 2-4 hours for mice (0.5 to 75 mg/kg, oral) .Animal Model:NOD-scid IL-2Rγnull (NSG) mice (23-36 g)Dosage:0.5 to 75 mg/kg Administration:Oral administration; twice daily; for 4 days Result:Had potent antimalarial activity with 90% effective dose (ED90) of 3 mg/kg per day (1.5 mg/kg twice daily).
