General description

A cell-permeable ureidocarboxamido thiophene compound that acts as a potent, reversible, and ATP-competitive inhibitor of IKK-2 (IC50 = 18 nM) with selectivity over IKK-1, JNK and p38 MAPK. Inhibits TNF-α production in human monocytes (IC50 in the range of 0.15-2.5 µM) and blocks IL-8 and IL-6 production by synovial fibroblasts (IC50 = 100 nM). Further reduces paw oedema in rat arthritis model (~100% inhibition at a dose of 30 mg per kg). A 10 mM (500 µg/179 µl) solution of IKK-2 Inhibitor IV (Cat. No. 401484) in DMSO is available.

The NF-kappaB family of transcription factors has been implicated in the propagation of ovarian cancer, but the significance of constitutive NF-kappaB signaling in ovarian cancer is unknown. We hypothesized that constitutive NF-kappaB signaling defines a subset of ovarian cancer susceptible
