adopting a DFG-in conformation, where the benzimidazole scaffold occupied the hinge region, the central aromatic ring occupied hydrophobic region I adjacent to the hinge region, and the hydrogen bond donor/acceptor bound to the hydrogen-bond-rich region. In comparison to lenvatinib, which had a docking score of −12.47 kJ mol−1 and a Glide E-model value of −132.68 kcal mol−1, compound 17 had a decent
目前用于药物发现和开发的方法之一是通过分子杂交从现有结构基序合成新型小化合物。本研究合成了一系列新的苯并咪唑[1,5- a ]咪唑、苯并咪唑[1,2- c ]噻唑、苯并咪唑三嗪和苯并咪唑[1,2- c ]喹唑啉支架。C-H 环胺化,使用无金属合成途径,作为针对乳腺癌 (MCF-7) 和肺癌 (A549) 癌细胞系的有效抗增殖抗血管生成分子。具有杂环的苯并咪唑支架的扩展导致占据 ATP 结合位点和相邻疏水口袋的三齿环状系统,通过额外的 H 键并完全占据入口区域,引发对 VEGFR2 的有希望的亲和力和选择性。分子对接研究表明,大多数设计的化合物与 VEGFR-2 结合采用 DFG-in 构象,其中苯并咪唑支架占据铰链区,中心芳环占据与铰链区相邻的疏水区 I,氢键供体 /受体与富含氢键的区域结合。与乐伐替尼相比,-1和-132.68 kcal mol -1的Glide E -模型值,化合物17具有-8
