Cat. No. 3318
Chemical Name: 4-Amino-[2',3'-bithiophene]-5-carboxa
Biological ActivityOrally active, ATP-competitive IKKβ inhibitor (IC50 = 3 - 12 μM) that displays > 10-fold selectivity over 28 other kinases including JNK, p38, MK2 and ERK. Attenuates NF-κB-induced gene expression of IL-6, IL-8 and COX-2 in synovial fibroblasts (IC50 values are 20, 20 and 8 μM respectively). Reduces iNOS induction and exhibits anti-inflammatory activity in vivo.
