Epidermal Growth Factor Receptor (EGFR) is a promising drug target for the discovery of cancer chemotherapeutics. EGFR tyrosine kinase inhibitors become resistant due to mutation after a certain period of clinical application. The objective of the present study is to identify edible mushrooms as EGFR inhibitors. Structure-based VS of mushroom compounds using Autodock Vina in PyRx, re-docking of top scored hits using Autodock 4.2 were performed. Molecular dynamics (MD) was carried out with top hits to investigate the dynamic nature of the active site followed by MMPBSA binding energy calculation and ADME study. Analysis of MD results revealed the stability of Ag_76, Ag_77, Ag_88 and Ag_340 in the active site of EGFR as potential binders. Comparison of docking and MD results with known inhibitors also claimed the effectiveness of these hits. The sources of these potential hits are , , and , which may be effective as anti-cancer food after in vitro studies.
表皮生长因子受体(EGFR)是发现癌症化疗药物的有前途的药物靶标。EGFR 酪氨酸激酶抑制剂在临床应用一定时间后会因突变而产生耐药性。本研究的目的是确定食用蘑菇作为 EGFR 抑制剂。使用 PyRx 中的 Autodock Vina 对蘑菇化合物进行基于结构的虚拟筛选,使用 Autodock 4.2 重新对接得分最高的命中。对 top hits 进行分子动力学 (MD) 研究,以研究活性位点的动态特性,然后进行 MMPBSA 结合能计算和 ADME 研究。MD 结果分析表明,Ag_76、Ag_77、Ag_88 和 Ag_340 在 EGFR 的活性位点中稳定,作为潜在配体。将对接和 MD 结果与已知抑制剂进行比较,也证明了这些命中的有效性。这些潜在命中的来源是 , , , ,它们在体外研究后可能作为有效的抗癌食品。
