Abstract
A simple, rapid, sensitive and reliable liquid chromatographic method for the quantification of BP-1107 in rat plasma has been established. Plasma samples were prepared by extraction with tert-butyl methyl ether, and troglitazone was used as an internal standard. The analytical separation was performed on a C18 column using acetonitrile–0.3% phosphoric acid in water (pH 4.00 adjusted with triethylamine) (75:25, v/v) as a mobile phase. A detailed validation of the method was performed as per USFDA guidelines. For BP-1107 at the concentrations of 2.42, 16.11 and 32.22 μg mL−1 in rat plasma, the extraction recoveries were 114.14 ± 9.75, 95.37 ± 12.06 and 90.00 ± 6.46%, respectively. The mean recovery for internal standard was 91.96 ± 2.51%. The lower limit of quantitation of BP-1107 was 16 ng. The linear quantification range of the method was 0.81–53.70 μg mL−1 in rat plasma with a correlation coefficient greater than 0.999. The intra-day and inter-day accuracy for BP-1107 at 2.42, 16.11 and 32.22 μg mL−1 levels in rat plasma fell between 97.10–110.02 and 97.52–108.04%. The intra-day and inter-day precision were in the ranges of 1.91–5.63 and 4.43–6.28%, respectively. The method was successfully applied to a pharmacokinetic study of BP-1107 in rats after an intravenous administration.
