γ-Secretase Inhibitor XI is a cell-permeable, active site directed, irreversible serine protease inhibitor that belongs to the class of isocoumarin analogs. The compound acts as a potent and selective inhibitor of γ-secretase and blocks the production of both amyloid-β40 and Aβ42 in HEK293 cells expressing wild-type and Swedish-mutant β-amyloid precursor protein (APP).
