is a leading cause of death in humans. Molecular targeted therapy for cancer has become a research hotspot as it is associated with low toxicity and high efficiency. In this study, a total of 36 derivatives of 4-(4-aminophenoxy)pyridinamide were designed and synthesized, based on the analysis of the binding patterns of cabozantinib and BMS-777607 to MET protein. Most target compounds exhibited moderate
癌症是人类死亡的主要原因。癌症分子靶向治疗因其低毒、高效而成为研究热点。本研究基于卡博替尼和BMS-777607与MET蛋白的结合模式分析,设计并合成了总共36种4-(4-氨基苯氧基)吡啶酰胺衍生物。大多数目标化合物对三种不同的细胞系(A549、HeLa 和 MCF-7)表现出中等至优异的抗增殖活性。共有7种化合物比卡博替尼具有更强的抑制活性,其中最有前景的化合物对A549细胞的IC50值为0.26 μM,是卡博替尼活性的2.4倍。对目标化合物的构效关系进行了分析和总结,并探讨了作用机制。吖啶橙(AO)染色实验和细胞周期凋亡分析表明,化合物剂量依赖性地诱导A549细胞凋亡,并主要将细胞阻滞于G0/G1期。化合物对 c-Met 激酶的 IC 值为 46.5 nM。进一步的对接研究和分子动力学模拟表明,该化合物与c-Met激酶形成了四个关键氢键,这些关键氨基酸在结合自由能方面发挥了重要作用。此
