Notes: γ-Secretase is a multi-subunit aspartyl protease that cleaves amyloid precursor protein (APP) and many other type 1 transmembrane proteins, including Notch, E-cadherin, and ErbB4. The proteolysis of APP by secretases produces beta amyloid (Aβ), a 39- to 42-amino acid peptide which forms the amyloid plaques that are characteristic of Alzheimer’s disease. DAPT is an inhibitor of γ-secretase, blocking the production of total Aβ in human primary neuronal cultures with an IC50 value of 115 nM and Aβ42 with an IC50 value of 200 nM.{18537} DAPT is also effective in vivo, reducing brain levels of Aβ when given orally to mice that are transgenic for human APPV717F or to rats.{18537,18534,18535} Through its effects on γ-secretase, DAPT indirectly inhibits Notch, affecting cell signaling and cell differentiation.{18536,18538}
