GtoPdb Ligand ID: 8880

PDB Ligand
Compound class: Synthetic organic
Comment: Compound IU1 is a reversible, small molecule inhibitor, discovered in a high-throughput study to identify inhibitors of the human proteasome-associated deubiquitinating enzyme USP14 [1]. Based on in vitro and in vivo results, the authors hypothesise that inhibition of USP14 may protect cells from the toxic effects of oxidised proteins produced in cells experiencing oxidative stress and that this may be a useful strategy for limiting the damaging effects of certain proteasome substrates associated with neurodegenerative diseases.
