DNA 高阶结构的自组装特性和多样性使可编程工具能够用于在分子水平上构建算法。然而,基于 DNA 的可编程工具的实用性受到与天然核酸的低正交性的阻碍,特别是在复杂的分子系统中。为了应对这一挑战,我们在此报告了通过使用非自然碱基对 (UBP) 形成对 DNA 自组装的正交调节。我们新设计的 UBP An N : Sy N是结合抗和不寻常的顺式糖苷构象形成的,具有高热稳定性和选择性。此外,一个C作为一种 pH 敏感的人工核碱基,在弱酸性条件(pH 6.0)下与胞嘧啶形成强碱基对。正交An N : Sy N碱基对作为杂交链反应的触发器,以提供长切口双链 DNA(约 1000 个碱基对)。这项工作代表了正交 DNA 自组装的第一个例子,它对自然的四字母字母 DNA 触发器没有反应,并扩展了在复杂环境中工作的可编程工具的类型。
Xanthine oxidase-activated prodrugs of thymidine phosphorylase inhibitors
摘要:
Thymidine phosphorylase (TP) is over-expressed in various tumour types and plays an important role in tumour angiogenesis, growth, invasion and metastasis. The enzymatic activity of TP is required for the angiogenic effect of TP, therefore, inhibitors of TP are of significant interest in cancer chemotherapy. A series of xanthine oxidase (XO) activated prodrugs of known inhibitors of TP have been designed and synthesized with the ultimate intent of improving tumour selectivity and pharmacokinetic characteristics. These prodrugs were not inhibitors of TP, but were selectively oxidized by XO at C-2 and/or C-4 of the uracil ring moiety to generate the desired TP inhibitor. Molecular modelling of both the TP inhibitors and XO-activated prodrugs rationalized their binding in the active site of the human TP crystal structure. (c) 2007 Elsevier Masson SAS.
