Inhibition Concentration, IC50(nM), of various Dox compounds

Compounds MCF-7 MDA-MB-231 MCF-7 (+ES)
Dox 602 ± 20 89 ± 7 585 ± 30
Dox-Linker 14 597 ± 20 86 ± 5 594 ± 20
AE-Dox 15 11 ± 6 90 ± 8 589 ± 3

The IC50 was estimated by using GraphPad™ 3-parameters curve fitting for 24 h drug exposure data points. All values are represented here, were evaluated in a duplicate of a triplicate count. Standard deviation was measured from the mean of six wells for each compound.
