is a dipeptidic gamma-secretase inhibitor with IC50 of 2.6 and 2.9 nM for the and Notch, respectively. YO-01027 is used as an anti-Alzheimer agent. YO-01027 the gamma-secretase complex. Unlike other gamma-secretase inhibitors,YO-01027 functional domain of the complex. YO-01027 targets the N-terminal Presenilin fragment gamma-secretase inhibitor Compound E (Cpn E), whereas DFK167 and DAPT, another inhibitors, bind to the catalytic site of the Presenilin aspartyl protease subunit
