Description: Potent, selective inhibitor of IKKβ
Chemical Name: 2-[(Aminocarbonyl)amino]-5-(4-fluorophenyl)-3-thiophenecarboxamide
Purity: ≥97% (HPLC)
Biological Activity for TPCA-1
TPCA-1 is a 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.
Compound Libraries for TPCA-1
TPCA-1 is also offered as part of the Tocriscreen 2.0 Max, Tocriscreen Kinase Inhibitor Library and Tocriscreen Antiviral Library. Find out more about compound libraries available from Tocris.
