---|---|---|---|---|---|---|---|
IC50 (μM) | SD | IC50 (μM) | SD | IC50 (μM) | SD | ||
7 | 0.78 | 0.02 | 7.17 | 0.53 | 1.72 | 0.09 | 9.19 |
10 | 0.52 | 0.08 | 5.56 | 1 | 10.15 | 0.73 | 10.69 |
cisplatin | 5.82 | 0.16 | 3.28 | 0.41 | 0.56 |
All values are expressed as mean ± standard deviation (SD) of three independent experiments. The degree of resistance was calculated by dividing the IC50 value of resistant cells by that of sensitive cells.
