AbstractIn this study, new quinazoline–chromene hybrid compounds were synthesized. The cytotoxic effects on cell viability of the hybrid compounds were tested against A549 human lung adenocarcinoma and BEAS‐2B healthy bronchial epithelial cell lines in vitro. In addition, the ability of the active compounds to inhibit cell migration was tested. Molecular docking studies were performed to evaluate the ligand–protein interactions, and molecular dynamics simulations were performed to determine the interactions and stability of ligand–protein complexes. In silico absorption, distribution, metabolism, and excretion (ADME) studies were conducted to estimate the drug‐likeness of the compounds. Compounds 4 (IC50 = 51.2 µM) and 5 (IC50 = 44.2 µM) were found to be the most active agents against A549 cells. They are found to be more selective against A549 cells than the reference drug doxorubicin. They also have the ability to significantly inhibit cell migration. They have the best docking scores against epidermal growth factor receptor (EGFR) (−11.300 and −11.226 kcal/mol) and vascular endothelial growth factor receptor 2 (VEGFR2) (−10.987 and −11.247 kcal/mol), respectively. In MD simulations, compounds 4 and 5 have strong hydrogen bond interactions above 80% of simulation times and showed a low ligand root mean square deviation (RMSD) around 2 Å. According to the ADME analysis, compounds 4 and 5 exhibit excellent drug‐likeness and pharmacokinetic characteristics.
摘要 本研究合成了新的喹唑啉-色烯杂化化合物。在体外测试了混合化合物对 A549 人肺腺癌和 BEAS-2B 健康支气管上皮细胞系细胞活力的细胞毒性作用。此外,还测试了活性化合物抑制细胞迁移的能力。分子对接研究评估了配体与蛋白质之间的相互作用,分子动力学模拟确定了配体与蛋白质复合物的相互作用和稳定性。还进行了吸收、分布、代谢和排泄(ADME)硅学研究,以估计化合物的药物亲和性。研究发现,化合物 4(IC50 = 51.2 µM)和化合物 5(IC50 = 44.2 µM)是对 A549 细胞最有效的药物。与参考药物多柔比星相比,它们对 A549 细胞的选择性更强。它们还能显著抑制细胞迁移。它们与表皮生长因子受体(EGFR)(-11.300 和 -11.226 kcal/mol)和血管内皮生长因子受体 2(VEGFR2)(-10.987 和 -11.247 kcal/mol)的对接得分最高。在 MD 模拟中,化合物 4 和 5 的氢键相互作用强度超过模拟次数的 80%,配体均方根偏差(RMSD)在 2 Å 左右,显示出较低的配体均方根偏差。根据 ADME 分析,化合物 4 和 5 表现出了极佳的药物相似性和药代动力学特征。
