Successful use of LC-NMR and LC-MS for rapid identification of an impurity in a novel antifungal drug icofungipen has been demonstrated. Complementary information obtained from the two methods made it possible to determine the structure of A1 prior to its isolation and purification. Stop-flow LC-NMR ((1)H and DQFCOSY), LC-MS and LC-MS/MS spectra have shown that A1 is structurally related to icofungipen. It was later isolated and prepared synthetically and its structure was corroborated by high-resolution NMR spectroscopy.
已证明成功使用液相色谱-核磁共振联用仪(LC-NMR)和液相色谱-质谱联用仪(LC-MS)快速鉴定新型抗真菌药物艾考芬净中的一种杂质。从这两种方法获得的互补信息使得在分离和纯化之前确定A1的结构成为可能。停流LC-NMR((1)H和DQFCOSY)、LC-MS和LC-MS/MS光谱表明A1在结构上与艾考芬净相关。后来它被分离出来并通过合成制备,其结构通过高分辨率核磁共振光谱得到证实。
