The stereoselective uptake of propranolol enantiomers was investigated by using the K562 and K562 adriamycin-resistant cell line (K562/ADR) as a model. An enantioselective RP-HPLC method was applied to determine the accumulation of propranolol (PPL) stereoisomers in K562 and K562/ADR cells. The concentration, time and temperature dependent studies showed that the accumulation of S-(-)-PPL was higher than R-(+)-PPL in K562 cells and uptake of R-(+)-PPL was significantly higher than that of S-(-)-PPL in K562/ADR cells. The results indicate the enantioselective accumulation of propranolol enantiomers in K562 and K562 / ADR cells. Chirality 25:361-364, 2013.
