NG25 is a potent dual TAK1 and MAP4K2 inhibitor, with IC₅₀s of 149 nM and 21.7 nM, respectively.

NG25 is a potent dual TAK1 and MAP4K2 inhibitor, with IC₅₀s of 149 nM and 21.7 nM, respectively. NG25 also potently suppresses several kinases such as LYN, CSK, FER, p38α, ABL,ARG and SRC, with IC₅₀s of 12.9, 56.4, 82.3, 102, 75.2, and 113 nM, respectively^[1]. NG25 is very potent suppressor of CpG B- or CpG A-stimulated secretion of IFNα and CL097-stimulated secretion of IFNβ, with complete inhibition by 400 nM^[2]. NG25 treatment reduces cell viability of all tested breast cancer cell lines in a dose dependent manner. NG25 (2 μM) enhances the cytotoxic effect of Dox on breast cancer cells^[3].

IRF7 is expressed in Escherichia coli as a glutathione S-transferase (GST) fusion protein with a PreScission proteinase cleavage site between the GST and the IRF7. The GST-IRF7 is captured on glutathione-Sepharose and IRF7 released from GST and glutathione-Sepharose by digestion with PreScission proteinase. His6-tagged IKKβ and TBK1 are expressed in their active phosphorylated forms in insect Sf21 cells and purified by affinity chromatography on nickel nitrilotriacetate-agarose. Active GST-IKKα is purchased from Millipore and assayed.

3.5×10⁵ Gen2.2 cells or Flt3-DCs are incubated for 1 h in 96-well plates without or with the indicated concentrations of inhibitor, then stimulated with 1 μM CpG (type A or B) or 1 μg/mL of CL097 or R848. After 5 or 12 h the cell culture supernatants are collected, clarified by centrifugation, and frozen at −80°C until cytokine levels are analyzed. For cell viability assays, unstimulated cells are incubated for 12 h in the absence or presence of inhibitors. Cells are then fixed and the percentage of live cells analyzed by flow cytometry.
