Abstract
A simple and rapid high performance liquid chromatography (HPLC) method was developed for the determination of BMS182874 (BMS) in mouse plasma. The drug was extracted from plasma by a liquid-liquid extraction process. The method consists of reversed-phase chromatography using a Thermo Hypersil-Keystone RP-18 5 μm, 250 × 2.1 mm column and UV spectrophotometer detection at 255 nm. The mobile phase consists of 45% (v/v) acetonitrile: 55% (v/v) trifluoroacetic acid (0.015% v/v; pH 3.0) at a flow rate of 0.6 ml/min. Validity of the method was studied and the method was precise and accurate with a linearity range from 100 ng/ml to 1000 ng/ml. The extraction efficiency was found to be 81, 84 and 87% for 100, 500 and 1000 ng/ml, respectively for spiked drug in plasma. The limit of quantification and limit of detection were found to be 50 and 10 ng/ml, respectively in plasma. Within-day and between-day precision expressed by relative standard deviation was less than 4% and inaccuracy did not exceed 4%. The assay was also used to analyze samples collected during animal studies. The suitability and robustness of the method for in vivo samples were confirmed by analysis of BMS from mouse plasma and tissues dosed with BMS.
