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.

Technical Data

Soluble to 100 mM in DMSO and to 10 mM in ethanol
>97 %
Desiccate at -20°C
