【摘要】 本文通过对已有小分子库进行虚拟筛选, 得到了可与BACE1活性中心Asp228、Asp32形成氢键作用的苯甲脒片段, 并在其基础上, 设计出了3-苯乙基苯甲脒类BACE1抑制剂。虽然活性测试结果显示这些化合物对BACE1的抑制活性较弱, 但是可以通过进一步的结构优化3-苯乙基苯甲脒类化合物来提高对BACE1的抑制活性。更多还原

【Abstract】 Computer aided fragment-based lead discovery has been successfully applied to the design of inhibitors of aspartyl protease enzyme β-secretase(BACE1).A benzimidamide fragment,which binds to the two catalytic aspartic acid residues in the active site of the enzyme,was selected as the starting compound.A novel series of 3-phenethylbenzimidamide inhibitors were designed and synthesized.Although biological evaluation results showed that the compounds displayed poor inhibitory activity towards BACE1,3-phenethylbenzimidamide analogs might be modified as potential BACE1 inhibitors.更多还原
