a IC50 values are half-maximal inhibitory concentrations required to block the growth stimulation of HG3 and PGA-1 cells. Values represent the mean ± SEM (error values × 10−6) for at least three experiments performed in triplicate at 24 h. Treatment at eight different concentrations (0.001–50 μM) was used for the determination of the IC50 values for each compound. b Predicted property using Chemaxon.
