are still on the way to human health. In this report, a series of novel thiosemicarbazone derivatives containing indole fragment were designed and synthesized. Most compounds exhibited excellent antiproliferative activity against PC3, MGC803 and EC109 cell lines with low micromolar IC50 (0.14-12μM). Especially, compound 5j can selectively inhibit PC3 cells in three tested tumor cells with IC50 value of
高效,安全的抗癌药物的研发仍在促进人类健康。在本报告中,设计并合成了一系列新型的含吲哚片段的硫半碳环素衍生物。大多数化合物对PC3,MGC803和EC109细胞系均表现出优异的抗增殖活性,且IC50(0.14-12μM)低。特别地,化合物5j可以选择性地抑制三个测试的肿瘤细胞中的PC3细胞,IC50值为0.14μM,这可能归因于将吲哚片段引入TSC结构后的协同作用。同时,与3-AP和DPC相比,化合物5j在PC3细胞中对两种正常的WPMY-1和GES-1细胞系表现出更高的选择性。我们还发现5j可以有效抑制PC3细胞增殖,定植并诱导细胞凋亡。更重要的是,5j可能通过阻止EMT过程来显着抑制迁移和侵袭,但对细胞周期没有影响。总体而言,我们的研究结果表明,具有吲哚硫半脲的结构的5j可以用作进一步优化和开发的有用的抗癌药物。
