Synthesis and evaluation of difluorophenylglycinols as new modulators of proteolytic processing of the amyloid‐β precursor proteins for Alzheimer's therapies were described. A range of N‐substituted (R)‐ and (S)‐difluorophenylglycinols, structured on the amino alcohol framework, were explored by incorporating the arylsulfonyl moieties and various N‐substituents. Evans' chiral auxiliary strategy was
描述了二氟苯基甘氨醇作为用于阿尔茨海默病治疗的淀粉样 β 前体蛋白的蛋白水解加工的新调节剂的合成和评估。通过结合芳基磺酰基部分和各种 N 取代基,探索了一系列在氨基醇框架上结构化的 N 取代的 (R)-和 (S)-二氟苯基甘氨醇。Evans 的手性辅助策略用于不对称合成这些对映体二氟苯基甘氨醇。在基于细胞的测定中评估了对 γ-分泌酶抑制和 ERK 介导的信号通路有影响的化合物。其中,N-环丙基甲基衍生物 R-12c 和 R-13c 表现出适度的 γ-分泌酶抑制以及 ERK 依赖性激活。
