摘    要:目的 :建立HPLC分离和检测人血浆中吡喃霉素 (Pir)的分析方法 ,并研究Pir在乳腺癌患者体内的药代动力学。方法 :以正定霉素为内标 ,1ml血浆加0 1ml(0 4mol/L ,pH=9 0)的氯化铵缓冲液碱化后以氯仿 -甲醇 (2∶1 ,v/v)混合溶剂提取2次。在Phe nomenex(C18)柱上 ,以0 04mol/L磷酸二氢钾 (pH=3 0)∶乙腈=68∶32为流动相 ,荧光检测波长480nm/550nm(Ex/Em )。结果 :血浆中Pir的线性范围5~1000ng/ml(r=0 9997) ,方法回收率为95 3 % ,日内及日间变异性RSD均小于5 % ;Pir在人体的药代动力学特征为开放性二室模型 ,消除相半衰期T1/2β、清除率CLs、表观分布容积Vd及曲线下面积AUC分别依次为 (12 8±5 9)h、(128 3±52 6)L/(m2·h)、(1754 3±478 2)L/m2 和 (428 7±137 2)ng/(h·ml)。结论 :本方法适用于临床Pir的血药浓度监测和药代动力学研究。

Abstract:AIM: To estabish a HPLC assay for the determination of pirarubicin(Pir) in plasma.METHODS: Daunomycin(DM) was used as the internal standard.Plasma samples were extracted with CHCl3∶ CH3OH(2∶ 1) .0.4M NH4Cl buffer(pH=9.0) solution: CH2OH(1∶ 9) and the internal standard were added.Separation was carried out on a 250mm× 4.6mm(5μ m) phenomenex column with 0.04M KH2PO4(pH=3.0) ∶ CH3CN(68∶ 32) as mobile phase.Fluorescent detector was set at an excitation wavelength of 480nm and an emission wavelength of 550nm.RESULTS: The calibration curves for serum Pir was linear over the range of 5~1 000ng/ml(r=0.9 997) .The recovery of Pir was 95.3% .The within-day and between-day variations were less than 5% .T1/2β , CLs, Vd and AUC of Pir were(12.8± 5.9) h, (128.3± 52.6) L/(m2· h) , (1 754.3± 478.2) L/m2 and (428.7± 137.2) ng/(h· ml) , respectively.CONCLUSION: The method is suited for monitoring blood concentration and pharmacokinetic study of Pir.
