摘要
目的 建立高效液相法测定大鼠血浆、尿和肝匀浆中 2′,3′ 二脱氢 2′,3′ 二脱氧核糖 2 氨基 6 环丙胺基嘌呤核苷 (Cyclo D4G ,D4G前药 )的简单而特异、适合于研究其体内药物代谢动力学的方法。方法 采用高效液相色谱法 ,C 18Hy persilODS柱 ,流动相为 7% (v v)乙腈的磷酸盐缓冲液 (pH 7 4 0 ) ,紫外检测波长为 2 83nm。结果 该方法的线性范围为0 5 - 80 μg·mL- 1 ,提取平均回收率 10 0 1% ,精确度为 99 4 % ,日内和日间差均小于 9 0 %。结论 Cyclo D4G在大鼠血浆中稳定 ,在肝匀浆中
Aim To develop a simple and specific high-performance liquid chromatographic(HPLC) method, suitable for the pharmacokinetic studies in vivo, to determine the concentrations of2-amino-6-cyclopropylamino-9-(2,3-dideoxy-β-D-glyceropent-2-enofuranosyl)purine (Cyclo-D4G, IMGprodrug) in rat plasma, urine and liver homogenates. Methods Chromatography was performed with C-18Hypersil ODS column and a mobile phase of 7% (v/v) acetonitrile in phosphate buffer, pH 7.40, withUV detection at 283 nm. Results The average extraction recovery of Cyclo-D4G in rat plasma and urinewas 100.1% over its linear range of 0.5 - 80 μg·mL^(-1). The accuracy of the assay was 99.4% .The intra-and inter-day RSDs were less than 9.0% . Conclusion The analytical method was found to beapplicable, reliable and suitable for pharmacokinetic studies.
