We herein report the discovery of a new γ-secretase modulator class with an aminothiazole core starting from a HTS hit (3). Synthesis and SAR of this series are discussed. These novel compounds demonstrate moderate to good in vitro potency in inhibiting amyloid beta (Aβ) peptide production. Overall γ-secretase is not inhibited but the formation of the aggregating, toxic Aβ42 peptide is shifted to smaller
我们在此报告了从HTS命中开始具有氨基噻唑核心的新型γ-分泌酶调节剂类别的发现(3)。讨论了该系列的合成和比吸收率。这些新型化合物在抑制淀粉样β(Aβ)肽产生方面显示出中等到良好的体外效力。总体上,γ-分泌酶没有被抑制,但是聚集的,有毒的Aβ42肽的形成转移到了较小的非聚集的Aβ肽上。化合物15以30 mg / kg po的剂量在APPSwe转基因小鼠体内降低了大脑Aβ42的含量
