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).

Cell permeable: yes

Primary Target
Aβ40 in vitro

Product does not compete with ATP.

Reversible: yes

Target IC₅₀: 7.9 µM for Aβ40; 7.6 µM for Aβ42 in vitro
