IKK-16 (IKK Inhibitor VII)
IKK-16 (IKK Inhibitor VII) is a novel inhibitor of IκB kinase (IKK) with the IC50 values of 0.04μM, 0.2μM and 0.07μM for IKK2, IKK1 and IKK complex, respectively [1].
IKK-16 (IKK Inhibitor VII) is a 2-benzamido-pyrimidines and selective inhibitor of IκB kinase (IKK). IKK-16 has been reported to effectively inhibit TNFα release into plasma upon LPS-challenge in the rat. In addition, IKK-16 has been found to be active at thioglycollate-induced peritonitis model in the mouse. Furthermore, IKK-16 has revealed to be an orally bio-available in rats and mice, and have significant in vivo activity in an acute model of cytokine release [1].

General tips | We do not recommend long-term storage for the solution, please use it up soon. |
Cell experiment [1]: | |
Cell lines |
HUVEC cells |
Preparation method |
The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
Reacting condition |
0.3-2μM |
Applications |
IKK-16 (IKK Inhibitor VII) inhibited IKK2 by the blockade of IκBα degradation and suppressed TNFα-stimulated expression of the adhesion molecules E-selectin, ICAM-1, and VCAM-1 in HUVEC cells. Moreover, IKK-16 also showed activity in the IFNγ-induced expression of the MHC molecules β2 microglobulin and HLA-DR, but its potency in these assays is 4- to 10-fold weaker than the adhesion molecules assay. |
Animal experiment [1]: | |
Animal models |
Rat model; thioglycollate-induced peritonitis model in the mouse |
Dosage form |
30 mg/kg, subcutaneous injection (sc) or oral administration for 5 h; or 10 mg/kg, sc |
Applications |
IKK-16 (IKK Inhibitor VII) inhibited TNFα release into plasma upon LPS-challenge in the rat model. Moreover, IKK-16 (IKK Inhibitor VII, 10 mg/kg, sc) resulted in a maximal inhibition of neutrophil extravasation in thioglycollate-induced peritonitis model. |
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
