Novel tricyclic sulfones as γ-secretase inhibitors have been reported by this laboratory for the treatment of Alzheimer’s disease. Compounds in this series have comparable or better in vitro activities and in vivo efficacies than sulfonamide analogues reported previously by this laboratory. Based on the previously reported tricyclic sulfone scaffold, additional SAR studies of C ring were carried out. Various C-ring structures including cyclohexane, pyran, and piperidine were tolerated. Additionally, the 7- and 8- positions of the C-ring were identified as the best sites to introduce substituent for modulating the pharmacokinetic properties of compounds from this series.
该实验室报告了新型三环砜作为γ-分泌酶抑制剂治疗阿尔茨海默氏症的情况。与该实验室之前报告的磺酰胺类似物相比,该系列化合物具有相当或更好的体外活性和体内功效。基于之前报告的三环砜骨架,对C环进行了额外的结构活性关系研究。包括环己烷、吡喃和哌啶在内的各种C环结构均被接受。此外,C环的7位和8位被确定为引入取代基以调节该系列化合物药代动力学特性的最佳位置。
