Ethanol weakens the specific interaction between the human red blood cell (RBC) glucose transporter GLUT1 and the inhibitor cytochalasin B (CB). The chromatographic retention volume of cytochalasin B on stationary phases consisting of GLUT1-containing membranes decreased with increasing ethanol concentration in the eluent. The apparent Kd values for the ethanol-GLUT1 interaction were 0.37, 0.45 and 0.64 M for red blood cells, red blood cell membrane vesicles and proteoliposomes, respectively, all much higher than the Kd values for D-glucose or cytochalasin B interaction with GLUT1. Ethanol also decreased the partitioning of cytochalasin B and drugs into phospholipid bilayers.
