Description: Dibenzazepine, also known as YO-01027 and Iminostilbene, is a potent γ-secretase inhibitor. Dibenzazepine also potently blocks amyloid precursor protein-like (APPL) and Notch cleavage. γ-Secretase is a fascinating, multi-subunit, intramembrane cleaving protease that is now being considered as a therapeutic target for a number of diseases. Potent, orally bioavailable γ-secretase inhibitors (GSIs) have been developed and tested in humans with Alzheimer's disease (AD) and cancer.
