小分子对核酸的调节是生命王国中的一个重要过程。用小分子靶向核酸代表了化学生物学前沿的重大挑战。核酸连接是自然界和设计材料中普遍存在的结构基序。在此,我们描述了一类新的基于三蝶烯骨架的结构特异性核酸连接稳定剂。三蝶烯提供DNA和RNA三向连接的显著稳定性,为构建具有增强的识别特性的核酸连接结合剂提供新的支架。此外,我们报告了两个人卵巢癌细胞系的细胞毒性和细胞摄取数据。
Nucleic acid modulation by small molecules is an essential process across the kingdoms of life. Targeting nucleic acids with small molecules represents a significant challenge at the forefront of chemical biology. Nucleic acid junctions are ubiquitous structural motifs in nature and in designed materials. Herein, we describe a new class of structure specific nucleic acid junction stabilizers based on a triptycene scaffold. Triptycenes provide significant stabilization of DNA and RNA three-way junctions, providing a new scaffold for building nucleic acid junction binders with enhanced recognition properties. Additionally, we report cytotoxicity and cell uptake data in two human ovarian carcinoma cell lines.
