hydroxyanthraquinone derivatives containing nitrogen-mustard and thiophene group were designed to covalently bind to topoisomerase II, and their structures were confirmed by nuclear magnetic resonance and high resolution mass spectrometer technologies in this article. The in vitro cytotoxicity against different cancer cell lines and one normal liver cell line (L02) was evaluated by MTT assay. Compound
设计了新型的含氮芥子基和噻吩基的羟基蒽醌衍生物与拓扑异构酶Ⅱ共价结合,并通过核磁共振和高分辨率质谱技术确定了它们的结构。通过MTT测定评估了针对不同癌细胞系和一种正常肝细胞系(L02)的体外细胞毒性。化合物A1是最有效的抗人肝癌HepG-2细胞的抗增殖剂(IC50 = 12.5μM),并且对正常肝组织L02细胞没有明显的生长抑制作用。化合物A1的良好细胞毒性和选择性表明它可能是进一步优化的有前途的线索。通过细胞凋亡的分析,进一步研究了化合物A1和A4的作用机理。共聚焦显微镜可追踪化合物A1在细胞中的位置,该化合物可进入细胞质和细胞核,并引起细胞核严重变形。对接研究表明,A1可以与拓扑异构酶II中的催化活性位点相互作用。
