Echinoderm microtubule-associated protein-like 4 (EML4)-anaplastic lymphoma kinase (ALK) is a valid therapeutic target for the treatment of EML4-ALK-positive non-small cell lung cancer (NSCLC). We discovered 12c as a novel and potent EML4-ALK inhibitor through structural optimization of 5a. In mice xenografted with 3T3 cells expressing EML4-ALK, oral administration of 12c demonstrated potent antitumor
棘皮动物微管相关蛋白样4(EML4)-间变性淋巴瘤激酶(ALK)是治疗EML4-ALK阳性非小细胞肺癌(NSCLC)的有效治疗靶标。通过5a的结构优化,我们发现12c是一种新型且有效的EML4-ALK抑制剂。在异种移植了表达EML4-ALK的3T3细胞的小鼠中,口服12c表现出有效的抗肿瘤活性。本文介绍了吡嗪-2-羧酰胺衍生物的合成和生物学评估,以及使用计算模型研究其结构-活性关系(SAR)。
