A series of amide-coupled bisanthrapyrazole derivatives of 7-chloro-2-[2-[(2-hydroxyethyl)methylamino]ethyl]anthra[1,9-cd]pyrazol-6(2H)-one (AP9) were designed using molecular modeling and docking and synthesized in order to develop an anticancer drug that formed a strongly binding bisintercalation complex with DNA. Concentration dependency for the increase in the DNA melting temperature was used to
一系列酰胺偶联的7-氯-2- [2-[([2-羟乙基)甲基氨基]乙基]蒽[1,9 - cd ]吡唑-6(2 H)的联蒽并吡唑衍生物使用分子建模和对接设计一个(AP9)并合成,以开发一种抗癌药物,该药物与DNA形成强结合双嵌入复合物。DNA融解温度升高的浓度依赖性用于确定DNA结合强度以及新合成的类似物是否发生双嵌入。还测量了化合物抑制人红白血病K562细胞系生长和抑制DNA拓扑异构酶IIα的脱级活性的能力。最后,通过测量拓扑异构酶IIα介导的DNA双链切割,评估了这些化合物作为拓扑异构酶II毒物的能力。所有的双蒽吡唑均在低微摩尔范围内抑制K562细胞的生长和拓扑异构酶IIα。具有两个或三个亚甲基接头的化合物与DNA形成双插层络合物,并与阿霉素一样强或更强地结合。总之,设计,合成了一组新的酰胺偶联双插入蒽吡唑化合物,并评估了其作为潜在抗癌剂的理化和生物学特性。
