摘　　要：目的采用骨架跃迁策略设计非核苷类NEDD8活化酶(NAE)抑制剂,并测试其抗肿瘤活性。方法通过23步反应以较高收率合成双磺酰胺类化合物14,通过1H NMR和MS确证其化学结构,采用MTT法测试体外抗肿瘤活性。结果化合物14对多种肿瘤细胞株显示出较好的活性,并呈剂量依赖性引起UBC12蛋白累积。结论化合物14是全新骨架的NAE抑制剂,在前列腺肿瘤细胞PANC-1中能显著引起细胞凋亡和细胞周期阻滞,为后续NAE抑制剂研究提供了一个有价值的先导化合物。Objective To develop novel NAE inhibitors with non-nucleoside scaffold by a scaffold hopping strategy and study the in vitro antitumor activities.Methods Disulfonamideindazole 14 was synthesized through 23 steps with a good yield.Its chemical structure was confirmed by 1H NMR and MS.MTT method was used to determine the in vitro antitumor activities.Results Compound 14 exhibited moderate antitumor activities against various cancer cells and promoted significant UBC12 accumulation in a dose-dependent manner.Conclusion Compound 14 is a potent NAE inhibitor with remarkable apoptosis induction and cell cycle arrest in prostate cancer PANC-1 cells.Our work provides a valuable leading compound for the further design and development of NAE inhibitors.
