derivatives with structure-specific binding towards dsRNA, indicating its potential for structure-selective ligands. Herein, we report the synthesis of novel fluorene/fluorenone derivatives and their selectivity towards various DNA structures, particularly G-quadruplexes, two of which showed strong affinity to the proto-oncogene c-myc promoter G-quadruplex.
能够选择性识别 G-四链体的荧光染料的开发对于研究其定位和生物学功能至关重要。然而,考虑到 G-四链体拓扑结构可能会有很大差异,合成显示出选择性和强荧光特性的化合物仍然是一个巨大的挑战。最近,我们开发了与 dsRNA 具有结构特异性结合的芴/芴酮衍生物,表明其具有结构选择性配体的潜力。在此,我们报告了新型芴/芴酮衍生物的合成及其对各种 DNA 结构的选择性,特别是 G-四链体,其中两种对原癌基因 c-myc 启动子 G-四链体显示出很强的亲和力。
