Epidermal growth factor receptor (EGFR) and vascular endothelial growth factor receptor 2 (VEGFR2) play an important role in cancer growth. Both of them have close relationships. Expression of EGFR will induce an angiogenic factor (VEGF) release for binding with VEGFR2. However, the existence of VEGF up-regulation independent of EGFR leads to cancer cell resistance to anti-EGFR. Therefore, a therapeutic approach targeting EGFR and VEGFR2 simultaneously may improve the outcome of cancer treatment. The present study was designed to identify potential compounds as a dual inhibitor of EGFR and VEGFR2 by the computational method. Firstly, the ligand-based pharmacophore model for each target was setup to screen of ZINC database of purchasable compounds. The hit compounds obtained by pharmacophore screening were then further screened by molecular docking studies. Taking erlotinib (EGFR inhibitor) and axitinib (VEGFR2 inhibitor) as reference drugs, six potential compounds (ZINC08398597, ZINC12047553, ZINC16525481, ZINC17418102, ZINC21942954, and ZINC38484632) were selected based on their docking scores and binding interaction. However, molecular dynamics simulations demonstrated that only ZINC16525481 and ZINC38484632 which have good binding free energy and stable hydrogen bonding interactions with EGFR and VEGFR2. The result represents a promising starting point for developing potent dual tyrosine kinases inhibitor of EGFR and VEGFR2.
表皮生长因子受体(EGFR)和血管内皮生长因子受体 2(VEGFR2)在癌症生长中起着重要作用。它们都有密切的关系。EGFR 的表达会诱导血管生成因子(VEGF)释放,与 VEGFR2 结合。然而,VEGF 的上调独立于 EGFR 的存在导致癌细胞对抗 EGFR 的耐药性。因此,同时针对 EGFR 和 VEGFR2 的治疗方法可能会改善癌症治疗的结果。本研究旨在通过计算方法鉴定潜在的化合物作为 EGFR 和 VEGFR2 的双重抑制剂。首先,为每个靶标建立基于配体的药效团模型,以筛选可购买化合物的 ZINC 数据库。通过药效团筛选获得的命中化合物然后通过分子对接研究进一步筛选。以厄洛替尼(EGFR 抑制剂)和阿昔替尼(VEGFR2 抑制剂)为参考药物,根据对接评分和结合相互作用,选择了六个潜在化合物(ZINC08398597、ZINC12047553、ZINC16525481、ZINC17418102、ZINC21942954 和 ZINC38484632)。然而,分子动力学模拟表明,只有 ZINC16525481 和 ZINC38484632 与 EGFR 和 VEGFR2 具有良好的结合自由能和稳定的氢键相互作用。该结果为开发有效的 EGFR 和 VEGFR2 双重酪氨酸激酶抑制剂提供了有希望的起点。
