4 Particularly, phloretin and quercetin, which are major components of apple juice, were potent in inhibiting OCT1-mediated atenolol transport with the inhibition constants of 38.0 and 48.0 microM, respectively. Atenolol solute carrier family 22 member 1 Homo sapiens
5 These results indicate that OCT1 is an atenolol transporter that may be involved in intestinal atenolol uptake and sensitive to fruit juices, although its physiological and clinical relevance remains to be further examined. Atenolol solute carrier family 22 member 1 Homo sapiens
