A simple, rapid and sensitive LC-MS/MS method for determination of trace amount of new antifungal drug iodiconazole in human plasma was developed (1-(1H-1,2,4-triazole)-2-(2,4-diflurophenyl)-3-[N-methyl-N-(3-chlor-benzyl)amino]-2-propanol), was used as internal standard (IS). The analytes were extracted by liquid-liquid extraction with n-hexane after internal standard spiked. The separation was performed by a ZORBAX SB-C(18) column (3.5 microm, 2.1 mm x 100 mm) with an isocratic mobile phase consisting of methanol-water-formic acid (50:50:0.05, v/v/v) at a flow rate of 0.3 mL/min. The lower limit of quantification (LLOQ) was 0.10 ng/mL. This method was successfully used to determine the concentration of iodiconazole in human plasma following dermal administration.
建立了一种简单、快速且灵敏的液相色谱-串联质谱法,用于测定人血浆中痕量新型抗真菌药物碘康唑(1-(1H-1,2,4-三唑)-2-(2,4-二氟苯基)-3-[N-甲基-N-(3-氯苄基)氨基]-2-丙醇),使用其作为内标(IS)。内标加入后,通过正己烷液-液萃取法提取分析物。采用ZORBAX SB-C(18)柱(3.5微米,2.1毫米×100毫米)进行分离,等度流动相由甲醇-水-甲酸(50:50:0.05,v/v/v)组成,流速为0.3毫升/分钟。定量下限(LLOQ)为0.10纳克/毫升。该方法成功用于测定经皮给药后人血浆中碘康唑的浓度。
