Preparation of radiolabeled sulfonamide HIV protease inhibitors, DMP852 and DMP853 is described. The C-14 labeling of DMP852 was accomplished by acylation of the intermediate amine with [1-14C]-chloroacetic anhydride followed by the treatment of the chloroacetyl derivative with methylamine. Due to the rapid loss of the methylglycine moiety during metabolism studies, a route that involved an oxidation-reduction sequence was employed to prepare tritium labeled DMP852. Similar methodology was utilized to prepare tritium labeled DMP853. Copyright © 2003 John Wiley & Sons, Ltd.
本文介绍了放射性标记磺
酰胺 HIV
蛋白酶抑制剂 DMP852 和
DMP853 的制备方法。
DMP852 的 C-14 标记是先用 [1-14C]-
氯乙酸酐酰化中间胺,然后用
甲胺处理
氯乙酰衍
生物。由于在代谢研究过程中
甲基甘
氨酸会迅速损失,因此采用了
氧化-还原顺序来制备氚标记的
DMP852。类似的方法也用于制备氚标记的
DMP853。Copyright © 2003 John Wiley & Sons, Ltd. All Rights Reserved.
