series of 4-anilinoquinazoline derivatives were designed and synthesized as novel c-myc promoter G-quadruplex binding ligands. Subsequent biophysical and biochemical evaluation demonstrated that the introduction of aniline group at 4-position of quinazoline ring and two side chains with terminal amino group improved their binding affinity and stabilizing ability to G-quadruplex DNA.

设计并合成了一系列4-苯胺基喹唑啉衍生物,作为新型c-myc启动子G-四链体结合配体。随后的生物物理和生化评估表明,在喹唑啉环的4位上引入苯胺基和两个带有末端氨基的侧链可提高它们对G-四链体DNA的结合亲和力和稳定能力。RT-PCR和Western blot结果表明,化合物7a可以下调Hela细胞中c-myc基因的转录和表达,这与靶向c-myc癌基因的有效G-四链体配体的行为一致。更重要的是,RTCA和菌落形成试验表明7a明显抑制Hela细胞增殖,而不影响正常的原代培养的小鼠肾小球系膜细胞。流式细胞仪检测表明7a诱导Hela细胞以时间依赖性和剂量依赖性方式停滞在G0 / G1期。
