We report herein the design and synthesis of bioisosteres of spirooxindole (MI-63/219), a small-molecule inhibitors of the MDM2–p53 interaction as anti-breast cancer agents. Compound 5b has been exhibiting significant anti-proliferative activity in nude mice bearing MCF-7 xenograft tumor. The compound 5b was found to act via modulation of MDM2 and p53 expression in breast cancer cells expressing wild
我们在此报告螺环吲哚(MI-63 / 219)(一种作为抗乳腺癌药物的MDM2-p53相互作用的小分子抑制剂)的生物等排体的设计和合成。化合物5b已经在带有MCF-7异种移植肿瘤的裸鼠中表现出显着的抗增殖活性。发现化合物5b在表达野生型p53的乳腺癌细胞中通过调节MDM2和p53表达起作用。化合物5b刺激p53激活,引起下游调节子p21,pRb和细胞周期蛋白D1的调节,从而调节细胞周期。因此,化合物触发了G1-S期细胞周期停滞,这在治疗的乳腺癌细胞的流式细胞仪分析中很明显。因此,化合物5b 恢复p53功能,该功能触发与G1 / S期细胞周期停滞相一致的分子事件。
