In Vitro	6-Mercaptopurine (6-MP) inhibits HEK293 and HEK293/MRP4 cells with IC50s of 2.81 and 14.11 μM, respectively. The combination of PU 23 (Cpd23) and 6-Mercaptopurine (6-MP) inhibits HEK293 and HEK293/MRP4 cells with IC50s of 1.84 and 6.06 μM, respectively[1]. Preincubation of HEK293/MRP4 cells with PU 23 (50 μM) for 2 h also significantly increases the amount of 6-MP in cells[1].
