摘要:

泽漆是一种天然植物, 因其抗肿瘤的特性而被广泛研究。然而, 对于淋巴结转移阳性的胃癌, 其治疗能力仍有待进一步研究。本研究旨在通过结合网络药理学、分子对接和分子动力学模拟的综合方法, 阐明泽漆在胃癌淋巴结转移治疗中的作用。首先, 确定并系统分析了泽漆与淋巴结转移阳性胃癌的共同靶点数据。随后进行分子对接, 验证主要成分与靶点之间的相互作用。最后, 采用分子动力学模拟, 通过MM-PBSA算法进行结合自由能的计算。结果表明, 在这种情况下, 泽漆主要的生物活性成分包括槲皮素和木犀草素, 靶向核心分子如EGFR和MMP9。其作用机制涉及的主要通路包括对EGFR酪氨酸激酶抑制剂的耐药性等。分子对接显示活性成分与关键靶点之间具有良好结合亲和力, 分子动力学和结合自由能分析显示木犀草素与MMP9之间具有稳定的相互作用。综上所述,在淋巴结转移阳性胃癌的治疗中, 泽漆具有多成分、多靶点、多途径的特点。该研究结果为其在肿瘤学中的潜在临床应用提供了有价值的理论依据。

Abstract:

Euphorbia helioscopia, a natural plant recognized for its anti-tumor properties, has been extensively investigated in various cancers. However, its therapeutic potential in gastric cancer with positive lymph node metastasis remains underexplored. This study aimed to elucidate the role of E. helioscopia in treating gastric cancer with lymph node metastasis using an integrative approach that combined network pharmacology, molecular docking, and molecular dynamics simulations. Initially, shared target data between E. helioscopia and gastric cancer with positive lymph node metastasis were identified and systematically analyzed. Subsequently, molecular docking was conducted to validate the interactions between key components and targets. Finally, molecular dynamics simulations were employed, with binding free energy calculations performed using the MM-PBSA algorithm. The findings revealed that the primary bioactive compounds of E. helioscopia in this context included quercetin and luteolin, targeting core molecules such as EGFR and MMP9. Key pathways implicated in its mechanism of action included resistance to EGFR tyrosine kinase inhibitors, among others. Molecular docking demonstrated robust binding affinity between the active compounds and critical targets, with molecular dynamics and binding free energy analyses highlighting a particularly stable interaction between luteolin and MMP9. In conclusion, E. helioscopia exhibited a multi-component, multi-target, and multi-pathway therapeutic profile in treating gastric cancer with positive lymph node metastasis. These findings offered valuable theoretical insights supporting its potential clinical application in oncology.
