4.0mg/ml Taking the 1 mL working solution as an example, add 20 μL of 200 mg/ml clarified DMSO stock solution to 300 μL of PEG300, mix evenly to clarify it; add 20 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 660 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 SC-514 (GK 01140) is an orally active, ATP-competitive IKK-2 inhibitor with IC50 of 3-12 μM, blocks NF-κB-dependent gene expression, does not inhibit other IKK isoforms or other serine-threonine and tyrosine kinases.
in vitro 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. [1]
in vivo 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%. [1]

キナーゼアッセイ Kinase assay
IKK complexes are immunoprecipitated from IL-1β-treated RASF cell lysates (0.5 –2 mg) using a NEMO antibody (3–10μg) followed by the addition of protein A-agarose beads. Antibody complexes are pelleted by centrifugation and washed 3 times with 1 mL of cold whole-cell lysis buffer followed by 2 washes in kinase buffer (25 mM HEPES, pH 7.6, 2 mM MgCl2, 2mM MnCl2, 10 mM NaF, 5 mM DTT, and 1mM phenylmethylsulfonyl fluoride). 100 –200 μg of immunoprecipitated IKK is analyzed for kinase activity in a reaction containing 10 μM biotinylated IκBα peptide as substrate and 1 μM [γ-33P]ATP (2500 Ci/mmol). After incubation at room temperature for 30 min, 25 μL of the reaction mixture is withdrawn and added to a SAM 96 biotin capture plate. After successive wash steps the plate is allowed to air-dry, and 25 μL of scintillation fluid is added to each well. Incorporation of [γ-33P]ATP is measured using a Top-Count NXT.
