polymerase (PARP) inhibitors have achieved great success in clinical application, especially for the prolonged survival of cisplatin-sensitive ovarian cancer patients. However, there are still many patients who do not respond to PARP inhibitors. Novel PARP inhibitors with higher activity are urgently needed. Herein we report a series of compounds by molecular hybridization PARP-1 inhibitor Olaparib (Ola)
聚(ADP-核糖)聚合酶(PARP)抑制剂在临床应用中取得了巨大成功,尤其是对于顺铂敏感型卵巢癌患者的延长生存期。但是,仍然有许多患者对PARP抑制剂无反应。迫切需要具有更高活性的新型PARP抑制剂。本文中,我们通过分子杂交PARP-1抑制剂Olaparib(Ola)与HSP90抑制剂C0817(一种姜黄素衍生物)报告了一系列化合物。评估了所有合成的化合物的体外抗增殖活性,并进一步评估了其对PARP酶的抑制活性和HSP90亲和力。我们的结果表明,化合物4可以与HSP90结合并引起静态淬灭,这表明化合物4能够与HSP90结合,下游分子乳腺癌1(BRAC-1)减少。总之,PARP和HSP90的双重靶标抑制剂对癌症表现出更强的选择性细胞毒性。
