| 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] |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
