Abstract
The cystic fibrosis transmembrane conductance regulator (CFTR) is a membrane protein that belongs to the same family as multidrug resistance-associated proteins whose main function is to expel xenobiotics and physiological organic anions from the cell interior. Despite the overall structural similarity with these membrane proteins, CFTR is not an active transporter but is instead a Cl− channel. We have tested the ability of known inhibitors of multidrug resistance-associated proteins to affect CFTR Cl− currents. We have found that sulfinpyrazone, probenecid, and benzbromarone are also inhibitors of CFTR activity, with a mechanism involving blockage of the channel pore.
