“Dixon plot analysis, corrected for nonfacilitated diffusion of SarCNU, revealed that epinephrine inhibited the uptake of SarCNU competitively, with a Ki of 163 +/- 15 microM, a value similar to the Km value for epinephrine influx in SK-MG-1 cells.”
“ Epinephrine was able to significantly inhibit the uptake of [3H]SarCNU , at a concentration of 50 microM, by 40%.”
