this study, we design a series of theophylline derivatives as novel ATAD2 inhibitors through fragment-based screening and scaffold growth strategy. A novel potent ATAD2 inhibitor (compound 19f) is discovered with an IC50 value of 0.27 μM against ATAD2, which adopts a combination of classic and atypical binding mode. Additionally, compound 19f could impede ATAD2 activity and c-Myc activation, induced significant
摘要 ATP酶家族AAA结构域蛋白2(ATAD2)因其致癌表观遗传修饰与癌细胞增殖、凋亡、迁移和耐药性密切相关,已成为热门的抗癌药物靶点。在本研究中,我们通过基于片段的筛选和支架生长策略设计了一系列茶碱衍生物作为新型ATAD2抑制剂。我们发现了一种新型有效的 ATAD2 抑制剂(化合物19f) ,其针对 ATAD2的 IC 50值为 0.27 μM,采用经典和非典型结合模式的组合。此外,化合物19f可以阻碍 ATAD2 活性和 c-Myc 激活,诱导显着的细胞凋亡,并在 BT-549 细胞中显示出抗迁移作用。总的来说,这些结果为开发用于三阴性乳腺癌(TNBC)治疗的新型有效 ATAD2 抑制剂提供了新的启示。
