Fig. 8. Effect of inhibitors on the formation of acetaminophen sulfate in BeWo cells.

Fig. 8

BeWo cytosolic homogenate was incubated with 250 μM acetaminophen and 100 μM 3′-phosphoadenosine-5′-phosphosulfate (PAPS) for 4 hours at 37°C in the absence and presence of different efflux transporter inhibitors (MK-571 inhibitors: MK-571, indomethacin, leukotriene C4; BCRP inhibitor: Fumitremorgin C). The reaction mixture was then analyzed for acetaminophen sulfate. Acetaminophen sulfate formed in the presence of inhibitors was normalized to the amount produced in the vehicle-treated controls. Data has been plotted as mean ± S.E.M. * indicates p < 0.05.
