Taking advantage of the structural similarity between aspartic proteases, small-molecule peptidomimetic inhibitors that already showed activity towards Secreted Aspartic Protease 2 as anti-Candida agents and HIV protease inhibitors were exploited as potential BACE1 inhibitors. A focused library of 6,8-dioxa-3-azabicyclo[3.2.1]-octane peptidomimetic scaffolds was synthesized and assayed towards BACE1
利用天冬氨酸蛋白酶之间的结构相似性,已利用小分子拟肽抑制剂作为潜在的BACE1抑制剂,该抑制剂已显示出对分泌天冬氨酸蛋白酶2的活性,并作为抗Candida药剂和HIV蛋白酶抑制剂。合成了一个聚焦的6,8-二氧杂-3-氮杂双环[3.2.1]-辛烷拟肽支架文库,并针对BACE1酶进行了分析,从而鉴定出了具有低微摩尔范围IC50的含硫内酰胺命中化合物,并且证实双环缩醛部分是与催化天冬氨酸残基相互作用的潜在过渡态类似物。
