The identification of highly selective small molecule di-substituted pyridinyl aminohydantoins as β-secretaseinhibitors is reported. The more potent and selective analogs demonstrate low nanomolar potency for the BACE1 enzyme as measured in a FRET assay, and exhibit comparable activity in a cell-based (ELISA) assay. In addition, these pyridine-aminohydantoins are highly selectivity (>500×) against
报道了鉴定出高选择性的小分子二取代的吡啶基氨基乙内酰脲作为β-分泌酶抑制剂。如在FRET分析中测得的那样,更有效和更具选择性的类似物对BACE1酶表现出低纳摩尔效价,并且在基于细胞的(ELISA)分析中显示出可比的活性。此外,这些吡啶-氨基乙内酰脲对其他结构相关的天冬氨酰蛋白酶BACE2,组织蛋白酶D,胃蛋白酶和肾素具有很高的选择性(> 500倍)。 我们的设计策略遵循传统的SAR方法,并得到了基于先前报道的氨基乙内酰脲3a的分子建模研究的支持。我们利用了S2'口袋处BACE1和BACE2之间的氨基酸差异(BACE1 Pro 70更改为BACE2 Lys 86)来构建对BACE2选择性> 500倍的配体。在此畸变附近在目标配体上添加大取代基已在配体和这两种蛋白质之间产生了空间冲突,从而影响了配体的亲和力和选择性。这些配体还显示出对组织蛋白酶D(> 5000倍)以及提到的其他天冬氨酰蛋白酶的
