摘要: 目的: 建立同时测定格列美脲(Glimepiride,G)及其活性代谢物羟基格列美脲(Hydroxyl-glimepiride,M1)血浆浓度的高效液相色谱-串联质谱(HPLC-MS/MS)法。方法: 血浆样品酸化后,经乙酸乙酯萃取后浓集进样,色谱柱为Phenomenex Gemini C18 (50 mm×3.0 mm,5 μm),甲醇∶水∶甲酸(80∶20∶0.1)为流动相,流速为 0.2 mL/min,柱温为室温,采用电喷雾(ESI) 离子源,多反应离子检测模式, 以格列齐特(Gliclazide,IS)为内标。G、M1和IS的检测离子对分别为质荷比(m/z) 491.4→352.4、507. 4→352.4、324.4→127.2。结果: G和M1的线性范围分别为 1.25~400 ng/mL 和 0.313~100 ng/mL,最低定量限分别为 1.25 和 0.313 ng/mL;批内批间精密度均小于10%,方法回收率均在 96.4% ~102.5%之间。结论: 该方法简便快速、特异性高,可用于同时测定G和M1血药浓度及其人体药代动力学的研究。

Abstract: AIM: To develop a sensitive liquid chromatography tandem mass spectrometry(HPLC-MS/MS)method for analyzing glimepiride(G)and its active metabolite hydroxyl-glimepiride(M1)in human plasma.METHODS: G and M1 were extracted from plasma samples by ethyl acetate after acidification,with gliclazide (IS) serving as an internal standard. The analytes went through the column of Phenomenex Gemini C18 (50 mm× 3.0 mm,5 μm) with mobile phase methanol-water-formic acid (80∶20∶0.1) and were analyzed under the multiple reaction monitoring mode using the eletrospray ionization (ESI) technique. The ion pairs being detected were( m/z) 491.4→352.4,507.4→352.4,324.4→127.2,respectively.RESULTS: The standard curves of G and M1 were linear in the range 1.25-400 ng/mL and 0.313-100 ng/mL,with a low limit of quantification of 1.25 and 0.313 ng/mL.The intra and inter day RSD were below 10%,with recovery rates ranging from 96.4% to 102.5%.CONCLUSION: The method is simple, rapid, sensitive, and suitable for the determination of glimepiride and its metabolite in human plasma.
