Catalog Number: 2559
Chemical Name: 2-[(Aminocarbonyl)amino]-5-(4-fluorophenyl)-3-thiophenecarboxamide
Biological Activity
Potent, selective inhibitor of IκB kinase (IKK) β (IC50 = 17.9 nM) that displays > 22-fold selectivity over IKKα and > 550-fold selectivity over other kinases and enzymes. Inhibits production of pro-inflammatory cytokines in vitro and in vivo and inhibits NF-κB nuclear localization. Reduces the severity and onset of collagen-induced arthritis; anti-inflammatory.

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?
