anti-proliferative activity. Their DNA-binding properties were also studied using UV–Vis spectroscopy, fluorescence spectroscopy, and circular dichroism. The results showed that such tri-substituted NDI as DNA intercalators exhibited strong π–π stack binding capability and high binding affinities towards calf thymus (Ct) DNA and G-quadruplex (G4) DNA. The order of the binding constants is Ct-DNA > G4 DNA, which
摘要设计并合成了一系列新型的带有2-氨基乙氧基乙胺侧链末端标记有叔氨基的水溶性三取代萘二酰亚胺(NDI)衍生物。新型萘二酰亚胺对癌细胞系(K562,A549和HeLa)的细胞毒性表明,这些化合物具有出色的抗癌活性,并且发现侧链较短(具有一个氧化乙烯)有利于观察到的抗癌性。增殖活动。还使用紫外可见光谱,荧光光谱和圆二色性研究了它们的DNA结合特性。结果表明,这种三取代NDI作为DNA嵌入剂表现出强大的π–π堆栈结合能力以及对小胸腺(Ct)DNA和G-四链体(G4)DNA的高结合亲和力。 图形概要设计并合成了一系列带有2-氨基乙氧基乙胺侧链末端标记有叔氨基的新型水溶性三取代NDI衍生物。这些化合物具有优异的抗癌活性,并且短链的侧链(具有一个氧化乙烯)将有利于其抗增殖活性。
