The syntheses of two novel glucuronide prodrugs of nitrogen mustard with a fluorine tag are reported. These prodrugs, which differ only by the presence or not of a spacer, were designed for selective activation in the necrotic area of tumors by β-glucuronidase. Kinetics of enzymatic hydrolysis of these prodrugs were determined by 19F-NMR and HPLC in vitro studies. The spacer-containing prodrug was found to be the more stable and more quickly cleaved than the other. Thereby it appeared to be a promising candidate for in vivo studies.
报道了两种带有氟标签的新型氮芥葡萄糖苷酸前药的合成。这些前药的区别仅在于是否存在间隔基,设计用于通过 β-葡萄糖醛酸酶选择性激活肿瘤坏死区域。通过 19F-NMR 和 HPLC 体外研究确定了这些前药的酶水解动力学。发现含有间隔基的前药比其他药物更稳定且裂解更快。因此,它似乎是体内研究的有希望的候选者。
