Application

SC-514 has been used to study its effect on lipopolysaccharide (LPS)-induced phosphorylation of NF-κB (nuclear factor-κB) p65 and p38 MAPK (mitogen-activated protein kinase).

Biochem/physiol Actions

SC-514 is a cell-permeable, potent and selective ATP competitive inhibitor of nuclear factor kappa-B kinase-2 (IKK-2) that specifically blocks NF-?B-dependent gene expression. SC-514 exhibits anti-inflammatory properties.
SC-514 is an amino-acetamide compound. It is selective for IKKβ with an IC50 value of 3−12 μM. SC-514 also inhibits cytokines such as interleukin-6 (IL-6) and IL-8, mediated by IKKβ. IKKβ is responsible for osteoclast survival, hence its inhibition affects osteogenesis.
