Simple and sensitive high-performance liquid chromatographic method for the determination of an everninomycin, SCH 27899, in rat plasma.
A simple and sensitive high-performance liquid chromatographic (HPLC) method was developed for the determination of SCH 27899, an everninomycin antibiotic, in rat plasma. The method involved plasma protein precipitation with acetonitrile, followed by reversed-phase HPLC analysis using a polymeric column and a mobile phase containing acetonitrile and ammonium phosphate, pH 7.8. The linear relationship between detector response and concentration was demonstrated with a correlation coefficient of larger than 0.996 at concentrations ranging from 0.2 to 100 microg/ml. The results showed that the HPLC method was accurate (bias < or = 6%) and precise (coefficient of variation, C.V. < or = 6%). The limit of quantitation was 0.2 microg/ml with a C.V. of 2.6% and bias of 5%. SCH 27899 was stable in rat plasma at -20 degrees C for at least 40 days. The HPLC method has been utilized for the determination of SCH 27899 in plasma samples from rats following single intravenous administration (3 mg/kg).
