non-camptothecin topoisomerase I (Top1) inhibitor by structure-based virtual screening. Herein, a series of 4-substituted derivatives were designed and synthesized. Most of them showed potent Top1 inhibitory activity. Their in vitro antiproliferative activity was also evaluated in A549, HCT-116 and ZR-75-30 human cancer cell lines. Compound 8s showed good antiproliferative activity with IC50 of 0.52μM and
以前,4-tosylanthra [1,2-c] [1,2,5]噻二唑-6,11-二酮(1)通过基于结构的虚拟筛选被鉴定为新型非喜树碱拓扑异构酶I(Top1)抑制剂。在此,设计并合成了一系列的4-取代的衍生物。他们中的大多数显示出强效的Top1抑制活性。还在A549,HCT-116和ZR-75-30人癌细胞系中评估了它们的体外抗增殖活性。化合物8s对HCT-116和ZR-75-30细胞株具有良好的抗增殖活性,IC50分别为0.52μM和0.42μM。Top1展开分析和分子建模研究使这种新型抑制剂的作用方式合理化。
