Iminoheterocycles as γ-secretase modulators

The synthesis of a novel series of iminoheterocycles and their structure–activity relationship (SAR) as modulators of γ-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 γ-secretase modulators, excellent rat pharmacokinetics, and lowering of Aβ42 levels in various in vivo models.
