TITLE:
摘要: 目的:建立测定瑞戈非尼原料药中有关物质的方法。方法:采用高效液相色谱法。色谱柱为Waters Atlantis T3 C18,流动相为0.1%三氟乙酸-乙腈(梯度洗脱),流速为1.0 ml/min,检测波长为232 nm,柱温为35 ℃,进样量为10 μl。结果:AFP-PMA脲(杂质A)、FP-二甲基吡啶甲酰胺(杂质B)、3,4-双-CTF-氨基甲酰胺基-PMA(杂质C)与主成分瑞戈非尼及其他未知杂质均能达到很好的分离;杂质A、B、C和瑞戈非尼检测质量浓度线性范围分别为0.511~5.108 μg/ml(r=0.999 9)、0.287~2.869 μg/ml(r=0.999 5)、0.360~3.604 μg/ml(r=0.999 9)和1.444~14.442 μg/ml(r=0.999 8);检测限分别为0.052、0.022、0.084和0.071 μg/ml;精密度、稳定性、重复性试验的RSD<3%;杂质A、B、C加样回收率分别为102.7%~106.3%、98.2%~102.9%、98.6%~104.3%,RSD分别为1.09%、1.83%、1.57%(n=9)。结论:该方法灵敏、快速、准确、可靠,可用于瑞戈非尼原料药中有关物质的测定。
ABSTRACT: OBJECTIVE: To establish a method for the determination of related substances in regorafenib. METHODS: Gradient elution HPLC was performed on the column of Waters Atlantis T3 C18 with mobile phase A of 0.1% Trifluoroacetic acid solution and B of acetonitrile (gradient elution) at a flow rate of 1.0 ml/min, the detection wavelength was 232 nm and column temperature was 35 ℃, injection volume was 10 μl. RESULTS: AFP-PMA urease (impurity A), FP- dimethyl pyridine carboxamide (impurity B),3,4-bis-CTF-aminoformamido-PMA (impurity C), regorafenib and other impurities were well separated; the linear range was 0.511-5.108 μg/ml for impurity A(r=0.999 9), 0.287-2.869 μg/ml for impurity B(r=0.999 5), 0.360-3.604 μg/ml for impurity C(r=0.999 9) and 1.444-14.442 μg/ml for regorafenib (r=0.999 8); the detection limit were 0.052,0.022,0.084 and 0.071 μg/ml,respectively; RSDs of precision, stability and reproducibility tests were lower than 3%; recoveries of impurity A, B and C were 102.7%-106.3% (RSD=1.09%,n=9), 98.2%-102.9% (RSD=1.83%,n=9) and 98.6%-104.3% (RSD=1.57%,n=9). CONCLUSIONS: The method is sensitive, rapid, accurate and reliable, and can be used for the determination of related substances in regorafenib.
