Catalog Number: 3922
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.

Molarity Calculator
Calculate the mass, volume or concentration required for a solution

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)
An example of a molarity calculation using the molarity calculator:
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
