SC-514 is a cell-permeable and selective inhibitor of IKK-2 with IC50 value of 3-12μM [1, 2].

SC-514 inhibits all forms of recombinant human IKK-2 with IC50 values in the 3–12μM range. It also inhibits the native IKK complex. SC-514 specifically binds at the ATP-binding site of IKK-2 and exerts a reversible and competitive inhibition with ATP. However, SC-514 shows non-competitive inhibition with the IκB site. As an inhibitor of IKK-2, SC-514 is found to block the phosphorylation and degradation of IκBα and reduce the translocation level of p65 into the nucleus in IL-1β-treated RASFs. Additionally, SC-514 shows dose-dependent inhibition in the transcription of NF-κB-induced genes, including IL-6, IL-8, and COX-2. Moreover, SC-514 shows efficacious in reduction of LPS-induced TNFα production in the acute model of inflammation. SC-514 is also reported to inhibit the osteoclastogenesis in BMM cells through attenuating RANKL-induced activation of NF-κB [1, 2].
