Human DNA topoisomerase II (TopoII) is highly correlated with cell proliferation, and involved in tumor biogenesis and development. The classic chemotherapeutic agents etoposide (VP-16) and adriamycin (ADR) targeting TopoII are wildly used in clinical applications. Herein, fifty-eight pinosylvin (1,2-diphenylethene) derivatives as TopoII inhibitors were designed and synthesized through three generations
人类DNA拓扑异构酶II(TopoII)与细胞增殖高度相关,并参与肿瘤的生物发生和发展。经典的化疗药物依托泊苷 (VP-16) 和靶向 TopoII 的阿霉素 (ADR) 在临床应用中得到广泛应用。在此,基于内部化学库中初始命中A1的结构,通过三代结构优化设计并合成了 58 种作为 TopoII 抑制剂的松果素 (1,2-二苯基乙烯) 衍生物。与VP - 16 ( IC 50 _α 110.0, β 36.1 μM) 用于 pBR322 DNA 松弛,在 DNA 切割试验中没有明显的 TopoII 毒物。同时,与VP -16 ( IC 50 1.5–15.1 微米)。F2对正常鼠细胞系 CCL-226 (IC 50 > 50 μM) 的细胞毒性低于 VP-16 (IC 50 20.8 μM)。F2和 VP-16 在细胞系中的选择性指数分别大于 52.1 和 1.3-26.2。此外,F2在
