體外研究
SC-514 inhibits the native IKK complex or recombinant human IKK-1/IKK-2 heterodimer and IKK-2 homodimer similarly. SC-514 inhibits transcription of NF-κB-dependent IL-6, IL-8, and COX-2 genes in IL-1β-induced rheumatoid arthritis-derived synovial fibroblasts (RASFs) with IC50s of 20, 20 and 8 μM. 100 μM SC-514 blocks the phosphorylation and degradation of IκBα and also reduces the level of translocation of p65 into the nucleus in IL-1β-treated RASFs SC-514 does not inhibit the phosphorylation and activation of the IKK complex. SC-514 induces a delay but not a complete blockade in IκBα phosphorylation and degradation. SC-514 treatment cells shows a slightly slowed, decreased import of p65 into the nucleus and a faster export of p65 from the nucleus. SC-514 inhibits the phosphorylation of either IκBα or p65 similarly.
體內研究
SC-514 is efficacious in an acute model of inflammation, namely LPS-induced serum TNF-α production. SC-514 (50 mg/kg, i.p.) inhibits TNF-αproduction in vivo by ~70%
