    Abstract:
    A liquid chromatography-tandem mass spectrometric method (LC-MS/MS) has been developed and validated to determine the concentration of Kendine 91 in mice plasma and tissues. Simvastatin was employed as the internal standard. Separation was performed on a C8 column, with a mobile phase consisting of methanol and aqueous 10 mM formic acid (73:27 v/v). Both analyte and internal standard were determined using electrospray ionization and the MS data acquisition was via multiple-reaction monitoring (MRM) in positive scanning mode. Quantification was performed using the transitions m/z 444-->169 and 441-->325 for Kendine 91 and simvastatin, respectively. The method was validated with respect to linearity, accuracy, precision, recovery and stability. This assay has been successfully applied to a pharmacokinetic study after intravenous injection of Kendine 91 in mice in a dose of 10mg/kg.
