  • PubMed Abstract: 
  • Genetic evidence points to deposition of amyloid-β (Aβ) as a causal factor for Alzheimer's disease. Aβ generation is initiated when β-secretase (BACE1) cleaves the amyloid precursor protein. Starting with an oxazine lead 1 , we describe the discovery of a thiazine-based BACE1 inhibitor 5 with robust Aβ reduction in vivo at low concentrations, leading to a low projected human dose of 14 mg/day where 5 achieved sustained Aβ reduction of 80% at trough level ...
