DSM705 hydrochloride, an orally active antimalarial compound, is a pyrrole-based Dihydroorotate Dehydrogenase (DHODH) inhibitor. DSM705 hydrochloride exhibits nanomolar potency against Plasmodium DHODH and Plasmodium parasites (IC50=95, 52 nM for P. falciparum and P. vivax DHODH, respectively), with no inhibition of mammalian DHODHs.

| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
