A rapid and sensitive liquid chromatography-tandem mass spectrometric method (LC-MS/MS) had been developed and validated to determine the concentrations of BPROL075 in rat plasma. After a simple protein precipitation of plasma samples by acetonitrile, BPROL075 was analyzed on a C-8 column at a flow rate of 0.5 mL/min. The mobile phase consisted of a mixture of 10 mM: ammonium acetate containing 0.1% formic acid and acetonitrile (20:80, v/v). Both BPROL075 (analyte) and the internal standard (BPR0L092) were determined using electro-spray ionization and the MS data acquisition was via multiple reactions monitoring (MRM) in positive scanning model. The MS/MS ion transitions monitored are m/z 342.2/195.2 and 312.5/165.2 for BPROL075 and BPROL092, respectively. The low limit of quantitation was 0.5 ng/mL. Each plasma sample was chromatographed within 5 min. The method was validated with respect to linearity, accuracy, precision, recovery, and stability. A good linear relationship was observed over the concentration range of 0.5-1000 ng/mL (r > 0.9994). Absolute recoveries ranged from 63.45 to 68.34% in plasma at the concentrations of 2, 40, 400, and 800 ng/mL. The intra- and inter-day accuracy ranged from 92.04 to 111.80%. Intra- and inter-day relative standard deviations were 1.08-3.29% and 1.96-5.46%, respectively. This developed and validated assay method had been successfully applied to a pharmacokinetic study after intravenous injection of BPROL075 in rats at a dose of 5 mg/kg.
