effect in the treatment of tumors but also provides a novel strategy for expanding the clinical application of PARP-1 inhibitors and overcoming resistance to PARP-1 inhibitors. Therefore, a series of dual PARP-1/2 and TNKS1/2 inhibitors were rationally designed, synthesized, and evaluated for their pharmacological properties. Among these candidates, compound I-9 showed excellent inhibitory activity as
聚(ADP-核糖)聚合酶-1 (PARP-1) 抑制剂是第一个也是最成功的药物,旨在利用 PARP-1 和 BRCA1/2 之间的合成致死率 (SL) 概念,为肿瘤治疗提供了一种新策略. 然而,适应证范围缩小和对 PARP-1 抑制剂的耐药性阻碍了其进一步的临床应用。通过靶向其他靶点诱导“BRCAness”,直接或间接干扰双链DNA断裂(DSBs)的同源重组(HR)修复途径,是扩大PARP-1抑制剂临床应用和克服耐药性的有前景的策略对这些抑制剂。Tankyrase1/2 (TNKS1/2) 通过调节 Wnt/β-catenin 信号传导参与非同源末端连接 (NHEJ) DNA 修复途径。TNKS1/2 还可以通过调节 Wnt 信号传导诱导“BRCAness”表型,从而增加具有 BRCA 能力的肿瘤细胞对 PARP-1 抑制剂的敏感性。这些结果表明,共同靶向 PARP1/2 和 TNKS1/2
