    • IKK-β activity: To measure the IKK-β activity we utilized the ELISA-based (K-LISA™) IKK-β activity assay (Calbiochem, V., Austria) with the conditions recommended by the manufacturer. The GST-IκBα 50-amino acid peptide that includes the Ser32 and Ser36 IKK-β phosphorylation sites is used as a substrate and incubated for 30 min at 30 °C with human recombinant IKK-β in a glutathione-coated 96-well plate, which allows substrate phosphorylation and capture in a single step. The phosphorylated GST-IκBα substrate was subsequently detected using anti-phospho IκBα (Ser32/Ser36) as first antibody, followed by the HRP-conjugated secondary antibody. The color development of the HRP substrate was monitored at 450 nm on a GeniosPro plate reader (Tecan, Austria) and the absorbance intensity was used as a measure for the IKK-β activity.

    • 2 overnight. On the next day, the cells were treated with the respective test compounds for 30 minutes, and further stimulated with 2 ng/ml human recombinant TNF-α for 6 h. After a lysis step, the luminescence of the firefly luciferase and the fluorescence of EGFP were quantified on a GeniosPro plate reader (Tecan, Austria). The luciferase signals derived from the NF-κB reporter were normalized by the EGFP-derived fluorescence to account for differences in the cell number and/or transfection efficiency.
