DNA interstrand cross-links (ICLs) are the clinically most relevant adducts formed by many antitumor agents. To facilitate the study of biological responses triggered by ICLs, we developed a new approach toward the synthesis of mimics of nitrogen mustard ICLs. 7-Deazaguanine residues bearing acetaldehyde groups were incorporated into complementary strands of DNA and cross-link formation induced by
DNA 链间交联 (ICL) 是临床上最相关的加合物,由许多抗肿瘤药物形成。为了促进对 ICL 引发的生物反应的研究,我们开发了一种合成氮芥ICL 模拟物的新方法。带有乙醛基团的 7-脱氮鸟嘌呤残基被整合到 DNA 的互补链中,并通过双还原胺化诱导形成交联。我们的策略能够以高产率和纯度合成大沟交联。
