DSM265 is a long-duration inhibitor of P. falciparum dihydroorotate dehydrogenase (PfDHODH) with an IC50 of 8.9 nM. DSM265 can also inhibit the growth of Pf3D7 parasites with an EC50 of 4.3 nM.
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) .
