of BACE1 enzyme, the development of nonpeptide inhibitors with optimal pharmacological properties is still highly demanding. In this work, we have discovered 2-aminobenzimidazole-containg ether scaffolds having potent and selective inhibitory potentials against BACE1 enzyme. We have synthesized novel 29 compounds and optimization of aryl linker region resulted in highly potent BACE1 inhibitory activities
由于BACE1酶的催化活性位点尺寸大且灵活性高,开发具有最佳药理性质的非肽抑制剂仍然非常困难。在这项工作中,我们发现了含有 2-氨基苯并咪唑的醚支架,对 BACE1 酶具有有效和选择性的抑制潜力。我们合成了 29 种新型化合物,并对芳基接头区域进行优化,产生了高效的 BACE1 抑制活性,EC 50值为 0.05–2.71 μM。芳氧基苯基类似物20j在酶测定中显示EC 50值低至0.07μM,而苄氧基苯基衍生物24b在酶测定中相对较不有效。但有趣的是后者在细胞测定中更有效(EC 50值 1.2 μM)。在使用 PC12-APP SW细胞的细胞测定中比较合成的衍生物时,化合物27f似乎是最有效的 BACE1 抑制剂,其 EC 50值为 0.7 μM。该支架还表现出比 BACE2 酶和组织蛋白酶 D 更高的选择性。此外,通过分子对接、分子动力学和 DFT 研究的结合,研究结果得到了支持。我们
