Dual-target-directed 1,3-diphenylurea derivatives were designed by hybridizing BACE 1 inhibitor 1 with metal chelator LR-90. A database consisted of 1,3-diphenylurea derivatives was built and screened by the pharmacophore model (Hypo 1) of BACE 1 inhibitor. Based on the predicted results, 11 compounds (6a–d, 9a–g) with favorable Fitvalues were selected, synthesized and evaluated for their BACE 1 inhibitory
通过将BACE 1抑制剂1与金属螯合剂LR-90杂交,设计了双靶标的1,3-二苯脲衍生物。建立了由1,3-二苯脲衍生物组成的数据库,并通过BACE 1抑制剂的药效团模型(Hypo 1)进行了筛选。根据预测结果,选择,合成了11种Fitfit值合适的化合物(6a - d,9a - g),并对其BACE 1抑制活性进行了评估,表明预测结果与实验值非常吻合。此外,合成的化合物还显示出螯合金属离子的能力。最有效的BACE 1抑制剂9f选择(27.85±2.46μmol/ L)进行进一步的受体结合研究,结果表明在9f的脲基团和催化天冬氨酸Asp228之间形成了必不可少的氢键。
