PDB Ligand
Compound class: Synthetic organic
Comment: Semagacestat is a small-molecule γ-secretase inhibitor that was developed by Eli Lilly as a potential treatment for Alzheimer's disease but it failed in Phase 3 clinical trials. NOTCH is also a γ-secretase substrate [3], and on-target inhibition of NOTCH receptor-related signalling by semagacestat treatment is proposed to be (at least in part) responsible for the unacceptable side effects that were noted in clinical trials, and which lead to termination of the trials [1].
