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 an ~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.
A cell-permeable dipeptide that suppresses Aβ production by blocking γ-secretase (Aβtotal IC50 = 115 nM, Aβ42 IC50 = 200 nM). Prevents Aβ34 generation in murine N2a cells and hAPP/hBACE-1 transfected human HEK 293 cells. Reported to be functionally active in both HEK 293 cells and neuronal cultures without affecting the secretion of amyloid-β precursor protein (APP). Also shown to lower Aβ levels acutely in APP-transgenic mice. Reported to reduce extracellular Aβ plaques and intracellular Aβ accumulation in 3xTgAD transgenic mice. A 25 mM (5 mg/462 µl) solution of γ-Secretase Inhibitor IX (Cat. No. 565784) in DMSO is also available.
