[摘要]：The synthesis of a novel series of iminoheterocycles and their structure-activity relationship (SAR) as modulators of gamma-secretase activity will be detailed. Encouraging SAR generated from a monocyclic core led to a structurally unique bicyclic core. Selected compounds exhibit good potency as gamma-secretase modulators, excellent rat pharmacokinetics, and lowering of A beta(42) levels in various in vivo models. (c) 2010 Elsevier Ltd.
