Discovery of novel triazolobenzazepinones as γ-secretase modulators with central Aβ42 lowering in rodents and rhesus monkeys
摘要:
Synthesis and SAR studies of novel triazolobenzazepinones as gamma secretase modulators (GSMs) are presented in this communication. Starting from our azepinone leads, optimization studies toward improving central lowering of A beta 42 led to the discovery of novel benzo-fused azepinones. Several benzazepinones were profiled in vivo and found to lower brain A beta 42 levels in Sprague Dawley rats and transgenic APP-YAC mice in a dose-dependent manner after a single oral dose. Compound 34 was further progressed into a pilot study in our cisterna-magna-ported rhesus monkey model, where we observed robust lowering of CSF A beta 42 levels. (C) 2015 Elsevier Ltd.

Compounds of formula I: Selectively attenuate production of Aβ(1-42) and hence find use in treatment or prevention of diseases associated with deposition of Aβ in the brain, in particular Alzheimer's disease.
