Abstract
Summary In this study, 21 structurally diverse drugs with examined central nervous system penetration were used for prediction of blood-brain barrier penetration using HPLC-UV instrument. Drugs' chromatographic capacity factors were measured by the immobilized artificial membrane presented by phosphatidylcholine column. The correlation between chromatographic capacity factor, octanol-water partition coefficient (log P) and molecular polar surface area (PSA) were determined at the physiological pH. The correlation factor 0.6677 with respect to log P and 0.7199 in reference to PSA was assigned. The developed in vitro prediction method may be used as a screening tool for blood-brain barrier penetration of drugs with passive transport mechanism.
