General description
A cell-permeable dipeptide that inhibits γ-secretase activity and suppresses Aβ production (Aβ total IC50 = 115 nM; Aβ42 IC50 = 200 nM). Reported to be functionally active in both HEK293 cells overexpressing human APP751 and neuronal cultures, however, it does not affect the secretion of amyloid-b precursor protein (APP). Effective in acutely lowering Ab in APPV717F-transgenic mice. Also effective in inhibiting the production of a ~6 kDa C-terminal cleavage product (CTFg) in HEK293 cells stably transfected with the Swedish mutant, βAPP695. Reported to reduce extracellular Aβ plaques and intracellular Aβ accumulation in 3xTgAD transgenic mice.
