dc.description.abstract | 7-O-Succinyl macrolactin A (SMA) and its major metabolite macrolactin A (MA) are generated from Bacillus polyfermenticus KIS-2. Both substances show inhibitory effects on angiogenesis and cancer cell invasion. SMA in rat plasma is known to be relatively stable at room temperature, but MA was not detected due to its instability. Therefore, a stabilizer is required to accurately measure the substance in biological rat samples. In this study, NaF and eserine were examined to determine whether they could stabilize MA to allow for accurate measurement in rat plasma. We also developed a rapid and simple chromatographic method using tandem mass spectrometry (MS/MS) for the simultaneous determination of these compounds in rat plasma. After simple protein precipitation with acetonitrile including methaqualone (internal standard), the analytes were chromatographed on a Hilic column with a mobile phase of 10 mM formic acid aqueous solution, methanol, and acetonitrile (15:15:70, v/v). The accuracy and precision of the assay were in accordance with FDA regulations for the validation of bioanalytical methods. This analytical method was successfully applied to monitor plasma concentrations of both compounds over time following intravenous administration of a salt form of SMA in rats. (C) 2014 Elsevier B.V.
