[摘要]：We report the discovery and optimization of a novel series of dihydrobenzofuran amides as gamma-secretase modulators (GSMs). Strategies for aligning in vitro potency with drug-like physicochemical properties and good microsomal stability while avoiding P-gp mediated efflux are discussed. Lead compounds such as 35 and 43 have moderate to good in vitro potency and excellent selectivity against Notch. Good oral bioavailability was achieved as well as robust brain A beta 42 lowering activity at 100 mg/kg po dose. (C) 2012 Elsevier Ltd. All rights reserved.
