Fig. 10. Reversibility of inhibition effect of various inhibitors on [14C]AA uptake in MDCK-MDR1 cells.

Fig. 10

Uptake of [14C]AA (23.5 μM) was measured in DPBS buffer (pH 7.4) at 37°C for 30 min after preincubating the cells with various inhibitors for 1 h and then washing off inhibitors with DPBS buffer before adding [14C]AA. The concentration of all inhibitors is 1 mM except that of 1, 4- di- iodo- benzene is 0.5 mM due to its solubility. X-axis labels stand for the substitute groups of benzene except AA for L-AA. Data are expressed as mean ± SD, n = 3–6. *: P < 0.05.
