Abstract
The "Notch-sparing" γ-secretase inhibitor (GSI) BMS-708,163 (Avagacestat) is currently in phase II clinical trials for Alzheimer's disease. Unlike previously failed GSIs, BMS-708,163 is considered to be a promising drug candidate because of its reported Notch-sparing activity for the inhibition of Aβ production over Notch cleavage. We now report that BMS-708,163 binds directly to the presenilin-1 N-terminal fragment and that binding can be challenged by other pan-GSIs, but not by γ-secretase modulators. Furthermore, BMS-708,163 blocks the binding of four different active site-directed GSI photoaffinity probes. We therefore report that this compound acts as a nonselective γ-secretase inhibitor.Entities:
