Abstract :
9-Nitrocamptothecin (9-NC) is an orally administered camptothecin (CPT) that is under evaluation in clinical trials. This compound is not fluorescent, which has hampered development of a sensitive high-performance liquid chromatographic (LC) assay for measurement of drug concentrations in clinical trials. We now report development of an assay that involves reduction of 9-NC to the fluorescent compound 9-aminocamptothecin (9-AC). The method is based on enzymatic reduction of 9-NC using bovine liver S-9 fraction. This method is validated to quantitate 9-NC and 9-AC in patient samples, and yields results comparable to those obtained with an LC/MS method.
