Abstact

Previous structure based optimization in our laboratories led to the identification of a novel, high-affinity cyclic sulfone hydroxyethylamine-derived inhibitor such as 1 that lowers CNS-derived Aβ following oral administration to transgenic APP51/16 mice. Herein we report SAR development in the S3 and S2' subsites of BACE1 for cyclic sulfoxide hydroxyethyl amine inhibitors, the synthetic approaches employed in this effort, and in vivo data for optimized compound such as 11d.
