analogues were resolved on a CSP based on (+)-(18-crown-6)-2,3,11,12-tetracarboxylic acid. Fendiline was resolved quite well with the separation factor (α) of 1.25 and resolution (RS) of 1.55 when a mobile phase consisting of methanol-acetonitrile-trifluoroacetic acid-triethylamine at a ratio of 80/20/0.1/0.5 (v/v/v/v) was used. The comparison of the chromatographic behaviors for the resolution of fendiline
芬迪林是一种有效的抗心绞痛治疗冠心病的药物,其十六种类似物在基于(+)-(18-crown-6)-2,3,11,12-四羧酸的CSP上拆分。当流动相由比例为80/20 / 0.1 / 0.5(v / v)的甲醇-乙腈-三氟乙酸-三乙胺组成的流动相时,芬迪林的分离度(α)为1.25,分离度(RS)为1.55 / v / v)。色谱分析法比较了芬迪林及其类似物的拆分行为,表明与芬迪林仲氨基键合的3,3-二苯丙基在手性识别中很重要,而苯基与苯丙氨酸之间的空间体积差异也很重要。芬迪林手性中心的甲基在手性识别中也很重要。
