IC50 values of jadomycin derivativesa
| Cell lines | IC50 (μM)b |
|||||
|---|---|---|---|---|---|---|
| 1 | 2 | 3 | 4 | 5 | 6 | |
| HepG2 | 10.8 | 100 | 49 | 27 | 9.8 | 27 |
| IM9 | 8.5 | 40 | 29 | 8.2 | 6.3 | 9.1 |
| H460 | 21.8 | 30.7 | 12.4 | NDb | 19.2 | 19.6 |
Human cancer cell lines HepG2, IM9 and H460 were treated continuously with jadomycin derivatives for 24 hours. Cytotoxicity was determined by the MTT/MTS assay as described in the text.
IC50 was calculated from survival curves of at least three independent experiments. ND, not determined.
