Abstract
En 中文
A simple and effective high-performance liquid chromatography with diode-array detection method coupled with a liquid liquid extraction pretreatment has been developed for determining the pharmacokinetics and tissue distribution of a novel structurally modified derivative (8-acetamino-isocorydine) of isocorydine. According to the in vivo experiments data calculations by DAS 2.0 software, a two compartment metabolic model was suitable for describing the pharmacokinetic of 8-acetaminoiso-corydine in rats. 8-Acetamino-isocorydine was absorbed well after oral administration, and the absolute bioavailability was 76.5%. The half-life of 8-acetamino-isocorydine after intravenous and oral administration was 2.2 h and 2.0 h, respectively. In Oro, 8-acetamino-isocorydine was highly distributed in the lungs, kidney and liver; however, relatively little entered the brain, suggesting that 8-acetaminoisocorydine could not easily pass through the blood brain bather. Our work describes the first characterization of the pharmacokinetic parameters and tissue distribution of 8-acetamino-isocorydine. The acquired data will provide useful infonnation for the in vivo pharmacology of 8-acetaminoisocorydine, and can he applied to new drug research.
