    Background
    
    DAPT, N-[N-(3,5-Difluorophenacetyl)-L-alanyl]-S-phenylglycine t-butyl Ester, is a potent and specific inhibitor of γ-secretase, a multimeric membrane protein complex that catalyzes proteolytic cleavage of amyloid precursor protein (APP) resulting in the accumulation of amyloi-β (Aβ) peptides which is associated with early on-set of familial Alzheimer’s disease (AD). It directly binds to the C-terminal fragment of the catalytic center of γ-secretase, presenilin (PS), especially within the transmenbrane domain 7 or more C-terminal region, resulting in the synthesis of a photoactivable DAPT derivative. Through oral administration, DAPT dose-dependently reduced Aβ peptides levels in vivo in Plasma and cerebrospinal fluid in young (6 months old, plaque-free) and aged (17 months old, plaque-bearing) Tg2576 mice.
