Chemical Name: 3-(4-Chlorophenyl)-4-[[[(4-chlorophenyl)amino]carbonyl]hydroxyamino]-5,5-dimethyl-2-oxo-1-imidazolidineacetic acid 2-[3-(5-nitro-2-furanyl)-2-propen-1-ylidene]hydrazide

Biological Activity

Potent inhibitor of endoplasmic reticulum associated protein degradation (ERAD). Specifically targets the p97-associated deubiquinating process (PAD) and inhibits ataxin-3 (atx3)-dependent deubiquitination. Also inhibits Sec61-mediated protein translocation at the ER. Displays cytotoxic activity preferentially against cancer cells; induces cell death via the proapoptotic protein NOXA.

Technical Data

Soluble to 100 mM in DMSO
>98 %
Desiccate at +4°C
