Inhibition of cell growth by the combination of o-PDA with other cytotoxic agents. MDA-MB-231 cells (1.25 × 104 cells/well) were incubated for 2 days in the presence of Doxorubicin (DOX, 5 μM) (a), Paclitaxel (PT 5 μM) (b) or cyclophosphamide (CY 10 mM) (c) with or without o-PDA (32 μΜ). Puromycin (25 mM) was used as a positive control. Cell growth was evaluated by colorimetric assays using WST-1 as an indicator. Experiments were repeated three times. Results were demonstrated as a mean ± SD of OD450. *p < 0.001 (calculated by Student’s two-tailed t test)
