Dendritic DNA molecules, referred to as DNA dendrons, consist of multiple covalently linked strands and are expected to improve the cellular uptake and potency of therapeutic oligonucleotides because of their multivalency. In this study, we developed an efficient synthetic method for producing DNA dendrons using strain-promoted azide–alkyne cycloaddition. Integration of the antitumor aptamer AS1411
树突状 DNA 分子(称为 DNA 树突)由多个共价连接的链组成,由于其多价性,有望提高治疗性寡核苷酸的细胞摄取和效力。在这项研究中,我们开发了一种利用菌株促进的叠氮-炔环加成反应生产 DNA 树枝的有效合成方法。将抗肿瘤适体 AS1411 整合到 DNA 树突中可增强癌细胞的细胞摄取和抗增殖活性。这些发现表明,将多价适体掺入DNA树突中可以有效增强其治疗效果。
