factor (VEGF)-neuropilin-1 (NRP1) interaction have been implicated in cancer, but reports on small-molecule inhibitors of VEGF-NRP1 interaction are scarce. Herein, we describe the identification of 1, a novel nonpeptide small-molecule NRP1 antagonist with moderate activity via structure-based virtual screening. Ensemble docking and molecular dynamics (MD) simulations of 1 were carried out and an interesting
血管内皮生长因子(VEGF)-神经纤维蛋白1(NRP1)相互作用的多方面作用已与癌症有关,但关于VEGF-NRP1相互作用的小分子抑制剂的报道很少。在这里,我们描述1,通过基于结构的虚拟筛选具有中等活性的新型非肽小分子NRP1拮抗剂的鉴定。进行了1的整体对接和分子动力学(MD)模拟,并获得了有趣的结合模型。我们发现,NRP1的Tyr297,Trp301和Tyr353所包围的“芳香盒”对于NRP1-1结合至关重要。基于源自MD模拟的结合模型对1的进一步结构修饰导致鉴定了具有显着改善的活性的12a。
