γ-Secretase Inhibitor XII-Calbiochem

C₂₀H₃₀N₂O₄

362.46

A cell-permeable, reversible dipeptide aldehyde that reduces Aβ production by blocking γ-secretase activity in vitro (Aβ₄₀ IC₅₀ = 7.9 µM; Aβ₄₂ IC₅₀ = 7.6 µM) and in cultured CHO 2b-7 cells that stably overexpress APP695 (Aβ₄₀ IC₅₀ = 11.5 µM; Aβ₄₂ IC₅₀ = 8.3 µM). Also blocks the generation of CTFγ (γ-secretase-generated carboxyl-terminal fragment). Does not affect the formation of amyloid-β-precursor protein (APP).
A cell-permeable, reversible dipeptide aldehyde that reduces amyloid-β protein (Aβ) production by blocking γ-secretase activity in vitro (Aβ₄₀ IC₅₀ = 7.9 µM; Aβ₄₂ IC₅₀ = 7.6 µM) and in cultured cells that stably over-express APP695 (Aβ₄₀ IC₅₀ = 11.5 µM; Aβ₄₂ IC₅₀ = 8.3 µM). Also shown to block the generation of γCTF (γ-secretase-generated carboxy-terminal fragment).
