inhibition, western blot assay and cell apoptosis detection. In summary, 9b effectively inhibited the activity of Topo I/II and induced DNA damage in CCRF-CEM cells and, moreover, significantly induced cell apoptosis in a concentration-dependent manner. These observations provide new information and guidance for the structural optimization of more novel acridine derivatives.
最初基于氨苯磺酸(m -AMSA)的结构设计和合成了一系列新型的N-苯基苯甲酰胺-4-甲胺a啶衍生物。分子对接表明,代表性化合物9a具有与DNA拓扑异构酶(Topo)II结合的亲和力,与m -AMSA相当,而且9a可以与Topo I发生优先相互作用。合成9a和类似物9b - 9f之后,这些都在体外进行了测试合成的化合物对三种不同的癌细胞系(K562,CCRF-CEM和U937)具有有效的抗增殖活性。其中,化合物9b,9c和9d对CCRF-CEM细胞表现出最高的活性,IC 50值为0.82至0.91μM。此外,9b和9d还显示出对U937细胞的高抗增殖活性,IC 50值分别为0.33和0.23μM。通过Topo I / II抑制,蛋白质印迹分析和细胞凋亡检测评估了这些化合物的药理学机理。综上所述,9b在CCRF-CEM细胞中有效抑制Topo I / II的活性并诱导DNA损伤,此外,以浓度依
