The invention relates to novel esters and in particular to some novel esters of glucuronide prodrugs of anthracyclines having tunable water-solubility, their synthesis and use in tumor-selective chemotherapy. It appeared that in the final step in the synthesis of these prodrugs, i.e. the coupling of the glucuronide spacer moiety to the parent drug molecule, protection of the sugar hydroxyls is, surprisingly, no longer required. A process for the preparation of these unprotected sugar spacer moieties is also disclosed.
本发明涉及新型
酯类,特别是一些具有可调

蒽环类药物
葡萄糖醛酸原药的新型
酯类,以及它们的合成和在肿瘤选择性化疗中的应用。在合成这些原药的最后一步,即
葡萄糖醛酸间隔物与母体药物分子的偶联过程中,似乎不再需要保护糖羟基,这一点令人惊讶。此外,还公开了制备这些未受保护的糖间隔物的工艺。
