Inhibition of [³H]-l-carnitine uptake in BeWo cells

Uptake of 10 nM [³H]-l-carnitine in BeWo cells was determined at 37°C for 30 min in the presence or absence (control) of inhibitors. Data were corrected for protein content and expressed as percentages of the control uptake. IC₅₀ values for each inhibitor were obtained by fitting the data presented in Fig. 5 as described in the text. The error represents the standard deviation from three or four IC₅₀ determinations. Inhibitors are listed in order of increasing IC₅₀ values.
