Table 3. hERG IC50 and Flt-3 IC50 values of selected compounds.
| Comp. No. | hERG IC50, μMa | Flt-3 IC50, nMa |
|---|---|---|
| 1 | 1.9 | NDb |
| SGI-1776 | <1.0 | NDb |
| 9 | >30 | 157 |
| 9a | >30 | 53 |
| 11a | >30 | 271 |

hERG IC50 was determined by WuXi AppTec using the QPatchHTX functional hERG assay as described in the experimental section. The Flt-3 IC50 of reference compound staurosporine was less than 1 nM.
Values represent the average of at least two separate experiments, and the standard deviation is less than 10% of the mean.
ND, not determined.
