Valacyclovir, a potential prodrug for the treatment of patients with herpes simplex and herpes zoster, and its analogs were resolved on two chiral stationary phases (CSPs) based on (3,3’‐diphenyl‐1,1’‐binaphthyl)‐20‐crown‐6 covalently bonded to silica gel. In order to find out an appropriate mobile phase condition, various mobile phases consisting of various organic modifiers in water containing various
Valacyclovir是一种潜在的治疗单纯疱疹和带状疱疹患者的前药,其类似物在基于(3,3'-diphenyl-1,1'-binaphthyl)-20-的两个手性固定相(CSP)上拆分Crown-6与硅胶共价键合。为了找出合适的流动相条件,将含有多种酸性改性剂的水中各种有机改性剂组成的各种流动相应用于伐昔洛韦及其类似物的拆分。当使用含有0.05 M,0.10 M或0.15 M高氯酸的水溶液中的30%乙腈作为流动相时,伐拉昔洛韦及其类似物在两种CSP上的分离系数(α)在2.49〜6.35和分辨率(R S)在2.95〜12.21的范围内。在这两种CSP之间,发现在二氧化硅表面上含有保护正辛基基团的残留硅烷醇的CSP比含有残留硅烷醇基的CSP更好。手性27:268-273,2015。©2015 Wiley Periodicals,Inc.
