G. To evaluate effects of IKBKE/TBK1 inhibition on NF-κB signaling in Ewing, TC32 cells were incubated with CYT387 for six hours prior to stimulation with TNF-α (30 ng/mL). IκBα degradation was measured by harvesting TC32 cells thirty minutes after stimulation with TNF-α. TNF-α stimulation resulted in degradation of IκBα, and this effect was attenuated with CYT387 treatment. Parthenolide, an inhibitor of IκBα phosphorylation was used as a positive control. Similar effects of CYT387 activity were seen in HEK-293T cells which also express IKBKΕ. Nuclear extracts were prepared from TC32 cells harvested following forty-five minutes of TNF-α stimulation. Treatment with CYT387 resulted in decreased nuclear localization of NF-κB family proteins RelA/p65 and c-Rel. There was a modest impairment of p50 nuclear localization as compared to parthenolide and DMSO controls and no change in p52 nuclear localization. RelB (not shown) is not expressed in TC32 cells

Induction of apoptosis by HDAC and DNMT1 inhibitors. a-c/ Membrane permeability apoptosis and necrosis assays were performed in which apoptotic cells positively stain for YO-PRO1 and necrotic cells positively stain for PI. Cells undergoing late apoptosis positively stain for both YO-PRO1 and PI. Nuclei were counterstained with Hoechst 33342. Apoptosis assay results are shown for Daoy cells that were exposed to: a/DMSO, b/2 μMparthenolide and c/2 μMparthenolide plus 33 nM 5-azadC, each for 24 h and 48 h, as indicated. d–f Annexin Vapoptosis assays of Daoy cells exposed to (d) DMSO, (e) 2 μMparthenolide and (f) 2 μM parthenolide plus 33 nM 5-aza-dC for 24 h. Nuclei were counterstained with DAPI.

PAR inhibited the production of TNF-α and IL-17 in vitro in a dose dependent manner. Lymph node MNCs harvested from EAN rats on day 8 p.i. were cultured in the presence of BPM and a series of concentrations of PAR. 72 h later, culture supernatants were collected and the levels of TNF-α and IL-17 were detected by ELISA. The results are expressed as mean ± SD (*p < 0.05, **p < 0.01). Data represented three experiments.

* 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.
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).
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.
