High-performance liquid chromatographic determination of acrolein as a marker for cyclophosphamide bioactivation in human liver microsomes

Abstract

A high-performance liquid chromatographic method for the quantification of acrolein following incubation of cyclophosphamide (CP) with human liver microsomes was developed. Based on the formation of the fluorescent derivative 7-hydroxyquinoline by condensation of acrolein with 3-aminophenol quantitation was performed without prior extraction or other sample cleanup procedures. The method showed sufficient sensitivity with a limit of detection of 5 ng/ml and a limit of quantification of 10 ng/ml. The suitability of the method is shown for enzyme kinetic studies.
