HPN-01 (IKK inhibitor XII) is a selective IKK inhibitor that inhibits IKK-α, IKK-β, and IKK-ε. HPN-01 reduces the severity of the disease, attenuates the immune imbalance, and prolongs the lifespan of mice in a model of autoimmune encephalomyelitis, and can be used to study immune disorders.

IKK2-IN-4(IKK2 Inhibitor VI) is a highly potent IKK-2 inhibitor with an IC50 value of 25 nM. IKK2-IN-4 inhibited the production of TNF-α in PBMC induced by LPS.

TBK1/IKKε-IN-5 ?is a dual TBK1 and IKKε inhibitor(IC50 of 1 nM and 5.6 nM respectively).
