series of 4-(3-1H-indazolyl)amino quinazoline derivatives were developed as PAK4 inhibitors based on a scaffold hopping strategy. Compounds 27e, 27g, 27i and 27j were found to exhibit potent inhibitory activity against PAK4 (IC50 = 10, 13, 11 and 9 nM, respectively). Subsequent cellular assay demonstrated that compound 27e possessed the strongest antiproliferative activity against A549 cells with an IC50
基于支架跳跃策略,开发了一系列新型 4-(3-1 H-吲唑基)氨基喹唑啉衍生物作为 PAK4 抑制剂。发现化合物27e、27g、27i和27j表现出针对PAK4的有效抑制活性(IC 50 分别=10、13、11和9nM)。随后的细胞实验表明,化合物27e对A549细胞具有最强的抗增殖活性,IC 50值为0.61 μM,略好于PF-3758309。进一步的抗癌机制研究表明,化合物27e以浓度依赖性方式显着诱导A549细胞凋亡,并阻断细胞周期G0/G1期。提出了化合物27e和PAK4之间的对接模型来阐明其可能的结合模式。作为一种有前景的PAK4抑制剂,化合物27e可作为开发新型PAK4靶向抗癌药物的候选药物。
