Compounda | Cell viability (%)b |
---|---|
Control | 100 |
H2O2 c | 45.41 ± 3.42# |
1 | 42.41 ± 2.35* |
2 | 51.46 ± 1.42* |
3 | 78.99 ± 3.49* |
4 | 61.99 ± 1.58* |
5 | 56.47 ± 1.70* |
EGCG (50 μM)d | 85.19 ± 2.17 |
The values shown are the means ± SE of at least three independent experiments.
aNG108-15 cells were pretreated with 4-phenylcoumarins (3.125–200 μM) for 2 h prior to exposure to H2O2 (2 mM). After incubation, cells were assessed by MTT to determine the percentage viability.
bCell viability was measured by MTT assay.
cH2O2-treated value differed significantly from the untreated control at the level of # P < 0.05.
dEGCG was used as standard positive control.
#Results differ significantly from H2O2-treated group compared to the control untreated group: P < 0.05.
∗Significantly from H2O2-treated group compared to the treatment group: P < 0.05.
