YO-01027, also known as dibenzazepine or DBZ, is a potent inhibitor of γ-secretase, a multisubunit aspartyl protease catalyzing the cleavage of numerous type I integral membrane proteins (such as amyloid precursor protein (APP) and Notch). YO-01027 also potently blocks amyloid precursor protein-like (APPL) and Notch cleavage, with estimated inhibition constant IC50 of 2.640.30 nM and 2.920.22 nM respectively, through interaction with the N-terminal fragment of Presenilin in a dose-response manner. Recent studies show that YO-01027-induced inhibition Notch signaling pathway leads to a rapid conversion of proliferative crypt cells into postmitotic cells and impairs MUC16 biosynthesis in a concentration-dependent manner in undifferentiated cells instead of postmiotic stratified cells at both preconfluent and confluent stages.
