IC₅₀ values for the three compounds are in μM, with pIC₅₀ values in brakets. The basal [³H]-D-Asp uptake data are based on the measured uptake in the chemotherapeutic-cells normalized to that in the relevant parental cell line on the experiment performed in duplicate. *) p <0.05,**) p <0.01,and ***) p <0.001, Compared to parental cell by two-tailed Student’s t-test
