γ-Secretase Inhibitor IX-CAS 208255-80-5-Calbiochem

C₂₃H₂₆F₂N₂O₄

MFCD04974585

A cell-permeable dipeptide that suppresses Aβ production by blocking γ-secretase (Aβ_total 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.
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.
