3 Figure S2. X-ray structure of 1 in complex with TAK1. A) The compound structure is superimposed on a Fo-Fc difference map contoured at 2.5σ (grey mesh). The map was calculated using initial phases after molecular replacement without including 1 in the model to avoid bias. B) Schematic overview of interactions between the TAK1 active site and 1. Hydrogen bonds are depicted by dashes and hydrophobic interactions by green contours. Figure S3. L929 cells were pre-treated with: A) indicated TAK1 (37), TAK1/MAP4K2 (1), selective MAP4K2 (12, 16, 17) and p38 inhibitors (38) at the concentration of 1 µm for 30 min; B) 1 at 0.1 µm and selective p38 inhibitor 39 at 0.1 and 1.0 µm and then TFα was added and incubated for 5 min. Samples were collected and subjected to Western blot. S3
