compounds 4e and 5b into the binding site of EGFR tyrosine kinase was performed to explains their possible binding mode and to compare it with known inhibitors. Moreover, molecular dynamic simulations were estimated for deeper understanding of the binding mode of compounds 4e and 5b at the binding site of EGFR tyrosine kinase. The findings indicated that the novel ligands 4e and 5b were stable in the
合理设计并合成了一系列 5-(4-pyridyl)-1,2,4-triazoles 与苯乙酮及其肟衍生物的杂化物作为表皮生长因子受体 (EGFR) 激酶抑制剂。最初,评估了所制备化合物的药物相似性和药代动力学特性。之后,制备的化合物在体外筛选了它们抑制 NCI-60 人癌细胞系生长的能力,其中某些化合物显示出中等活性。化合物4e和5b作为该系列中最有效的化合物出现,进一步测试了它们的 EGFR 酶抑制活性。他们显示 IC 50值分别为 0.14 和 0.18 µM,与作为 IC 参考的吉非替尼相比50值为 0.06 µM。将化合物4e和5b对接到 EGFR 酪氨酸激酶的结合位点,以解释它们可能的结合模式并将其与已知抑制剂进行比较。此外,估计分子动力学模拟以更深入地了解化合物4e和5b在 EGFR 酪氨酸激酶结合位点的结合模式。结果表明,新型配体4e和5b在 EGFR 酪氨酸激酶活性位点稳定。
