Chemical Name: 5-Chloro-1-[(2,5-dichlorophenyl)methyl]-1H-indole-2,3-dione 3-(O-acetyloxime)

Biological Activity

Inhibitor of ubiquitin C-terminal hydrolase-L1 (UCH-L1) activity (Ki = 0.4 μM). Causes cell death through the apoptosis pathway; increases levels of highly ubiquitinated proteins and decreases ubiquitin proteasome activity. Activity leads to dramatic alterations in synaptic protein distribution and spine morphology in vivo.

Technical Data

Soluble to 50 mM in DMSO
>98 %
Desiccate at +4°C
