We have identified potent isophthalic acid derivatives armed with imidazol and indolyl groups as potent β-secretase inhibitors. The most effective analogs demonstrated low nano-molar potency for the BACE1 (β-secretase cleaving enzyme) as measured by FRET (Fluorescence Resonance Energy Transfer) and cell-based (ELISA) assays. Our design strategy followed a traditional SAR approach and was supported
我们已经确定,带有咪唑和吲哚基的有效间苯二甲酸衍生物是有效的β-分泌酶抑制剂。通过FRET(荧光共振能量转移)和基于细胞的(ELISA)分析法测定,最有效的类似物显示出BACE1(β-分泌酶裂解酶)的纳摩尔浓度低。我们的设计策略遵循传统的SAR方法,并基于先前报道的衍生自间苯二甲酸I的羟乙烯过渡态抑制剂的分子建模研究得到了支持。在FRET分析中,最有效的化合物10a的BACE1的IC 50值为75 nM,并且具有细胞活性,EC50值为0.81μM。另一方面,化合物11b被发现是基于细胞的测定中最有效的化合物,EC 50值为0.29μM。
