the present study describes compound BP44 with high selectivity for BRD4 and PARP1. Fortunately, BP44 inhibits the homologous recombination in triple-negative breast cancer (TNBC) and triggers synthetic lethality, thus leading to cell cycle arrest and DNA damage. In conclusion, we optimized the BRD4-PARP1 inhibitor based on previous studies, and we expect it to become a candidate drug for the treatment
聚(ADP-核糖)聚合酶(PARP)抑制剂的有效效力和抗性限制了它们的应用。在这里,基于先前发现的含溴结构域蛋白 4 (BRD4) 和 PARP1 之间潜在的合成致死效应,我们利用一种模拟乳腺癌易感基因 (BRCA) 突变的影响的新范例来触发合成致死的可能性。 . 因此,本研究描述了对 BRD4 和 PARP1 具有高选择性的化合物BP44 。幸运的是,BP44抑制三阴性乳腺癌 (TNBC) 中的同源重组并触发合成致死性,从而导致细胞周期停滞和 DNA 损伤。综上所述,我们在前期研究的基础上对BRD4-PARP1抑制剂进行了优化,我们期待它在未来成为治疗TNBC的候选药物。该策略旨在扩大 PARPi 在 BRCA 能力的 TNBC 中的使用,以创新方法解决未满足的肿瘤学需求。
