---|---|---|
cell line | (R)-1 | (S)-1 |
MCF-7 untrasfected | 250 ± 6.5 | 99 ± 3.5 |
MCF-7 siNMDA R | 210 ± 2.3 | 520 ± 8.7 |
SKBR3 untrasfected | 74 ± 4.8 | 23 ± 2.8 |
SKBR3 siNMDA R | 66 ± 1.9 | 57 ± 1.3 |
Cells were treated for 48 h with different doses of (R)-1 and (S)-1. Cell viability was determined by SRB assay. Data are expressed as mean ± SE of three separate experiments.
