Inhibition of arteether O-deethylase activity by selected antimalarial drugs in human liver microsomes3-a
| Drug | IC50 (μM) |
|---|---|
| Chloroquine | >500 |
| Halofantrine | 19 |
| Mefloquine | 92 |
| Quinine | >500 |
| Quinidine | 235 |
↵3-a Arteether (100 μM) was incubated with increasing concentrations of each antimalarial drug. DQHS production was measured in human liver donors 7 and 18, and the IC50 values were calculated as described in Materials and Methods.
