Abstract

We have developed and validated a practical high-performance liquid chromatography method to determine the concentration of N- diisopropyloxyphosphoryl-valine-phenylalanine-3, 4, 5-trimethoxy aniline (DIPP-Val-Phe-TMOA) in Adriamycin-resistant human breast adenocarcinoma (MCF-7/ADR) cells. First, DIPP-Val-Phe-TMOA was extracted from MCF-7 cells with perchloric acid, followed by a cleanup procedure with centrifugal separation, and then determinated by HPLC using a Waters C18 column with a gradient elution (solvent A: 10 mM ammonium acetate at pH 7.0, B: acetonitrile). The flow rate was maintained at 1.0 ml/min at room temperature. The detection wavelength was at 254 nm. Meanwhile, this validated method was successfully applied to analyze the concentration levels and the pharmacokinetics parameters of DIPP-Val-Phe-TMOA in MCF-7/ADR cells.
