Two different schemes of novel substituted quinoline derivatives were designed and synthesized via simple reaction steps and conditions. A comparative molecular docking study was carried out on two different types of EGFR enzymes which include wild-type (PDB: 4I23) and T790M mutated (PDB: 2JIV) respectively. Compounds were also validated upon T790M/C797S mutated (PDB ID: 5D41) EGFR enzyme at the allosteric
通过简单的反应步骤和条件设计并合成了两种不同的新型取代喹啉衍生物方案。对两种不同类型的 EGFR 酶进行了比较分子对接研究,分别包括野生型(PDB:4I23)和 T790M 突变型(PDB:2JIV)。还在变构结合位点的 T790M/C797S 突变(PDB ID:5D41)EGFR 酶上验证了化合物。进行自由能扰动以确定 ΔG结合形式的蛋白质 - 配体复合物的绝对结合自由能,这反过来提供4ab和5ad通过确定的初始支架中的结构增强成为最有潜力的竞争者。通过标准 MTT 分析检测合成衍生物对 HCC827、H1975 (L858R/T790M)、A549 和 HT-29 细胞系的抗癌活性。化合物4ad (6-chloro-2-( isoindolin -2-yl)-4-methylquinoline) 对突变型 EGFR 激酶显示出优异的抑制活性,IC 50值为 0.91 µM。 通过 insilico
