InSolution γ-Secretase Inhibitor X-Calbiochem

产品说明

一般描述

A cell-permeable hydroxyethylene dipeptide isostere that acts as a potent and highly specific inhibitor of γ-secretase (Aβ total IC₅₀ = 17 nM; Aβ₄₀ IC₅₀ = 48 nM; and Aβ₄₂ IC₅₀ = 67 nM in SH-SY5Y cells overexpressing spβA4CTF). Binds to presenilin and blocks Notch intracellular domain production. Also reported to block the formation of εCTF, resulting in the accumulation of α- and βCTF. Functions as a transition state analog mimic at the catalytic site of an aspartyl protease, however, it exhibits over 100-fold greater selectivity for γ-secretase than for cathepsin D.
