and bromo-substituted mansonone E derivatives with triazole moieties at the C-3 position were prepared by using copper-catalysed azide–alkyne cycloaddition click chemistry. These compounds were found as potent inhibitors of topoisomerase II (Topo II) and topoisomerase I (Topo I). The Topo II-mediated pBR322 DNA relaxation and cleavage assay showed that the derivatives might act as catalytic inhibitors
通过使用铜催化的叠氮化物-炔烃环加成点击化学,制备了两个在C-3位置带有三唑部分的新颖的C-9氯和溴取代的曼森酮E衍生物系列。发现这些化合物是拓扑异构酶II(Topo II)和拓扑异构酶I(Topo I)的有效抑制剂。Topo II介导的pBR322 DNA弛豫和裂解试验表明,这些衍生物可能起催化抑制剂的作用。评估了它们对A549,HL-60,K562和HeLa细胞的细胞毒活性,表明这些化合物是有效的抗肿瘤剂。它们的结构活性关系和分子对接研究表明,三唑的取代基对细胞毒性特别重要。
