effects, and evaluate their capabilities for conformational photoregulation. 4,4′-Diaminoazobenzene derivatives were found to moderately stabilize quadruplex structures but not affect conformational photoregulation. This work further develops the design and general understanding of the stabilization effects of small molecules with telomeric G-quadruplex DNA.
稳定G-四链体结构的小分子的发展已引起抗癌药物发现的极大关注。本文中,我们报道了几种具有不同取代基的4,4'-二氨基偶氮苯衍生物的合成及其结合和稳定端粒G-四链体DNA的能力。进行圆二色性(CD)光谱来表征四重体拓扑,测量稳定化效果并评估其构象光调节的能力。发现4,4'-二氨基偶氮苯衍生物可适度稳定四链体结构,但不影响构象光调节。这项工作进一步发展了对端粒G-四链体DNA小分子的稳定作用的设计和一般理解。
