S8922 TBK1/IKKε-IN-1(compound 1) TBK1/IKKε-IN-1 (compound 1) is a dual inhibitor of TANK-binding kinase 1 (TBK1) and IκB kinase-ε (IKKε/IKK-i) with IC50 of 1.0 nM and 5.6 nM for TBK1 and IKKε, respectively. TBK1/IKKε inhibition enhances response to PD-1 blockade, which effectively predicts tumor response in vivo.

S8935 BAY-985 BAY-985 is a potent and highly selective TBK1/IKKε inhibitor. BAY-985 shows high potency toward TBK1 (IC50 = 2 nM, low ATP assay; 30 nM, high ATP assay) and IKKε(IC50 = 2 nM), as well as high potency in the mechanistic pIRF3 assay (IC50 = 74 nM), and an antiproliferative effect on SK-MEL-2 cells (IC50 = 900 nM).
S9042 Wedelolactone Wedelolactone, a medicinal plant-derived natural compound, is an inhibitor of IKK that is critical for activation of NF-κB by mediating phosphorylation and degradation of IκBα. Wedelolactone is also an inhibitor of caspase-11.

S9184 Forsythoside B Forsythoside B is a phenylethanoid glycoside isolated from the leaves of Lamiophlomis rotata Kudo, a Chinese folk medicinal plant. Forsythoside B has potent neuroprotective effects and has anti-inflammation, antioxidant, and antisepsis properties. Forsythoside B could inhibit TNF-alpha, IL-6, IκB and modulate NF-κB.
S9417 Homoplantaginin Homoplantaginin (Hispidulin-7-glucoside), a main flavonoid from a traditional Chinese medicine Salvia plebeia, has anti-inflammatory and anti-oxidant properties. Homoplantaginin inhibits TNF-α and IL-6 mRNA expression, IKKβ and NF-κB phosphorylation.
S7441 WS3 WS3 is a β cell proliferation inducer via modulation of Erb3 binding protein-1 (EBP1) and the IκB kinase pathway.

S7442 WS6 WS6 is a β cell proliferation inducer via modulation of Erb3 binding protein-1 (EBP1) and the IκB kinase pathway.
S6386New MRT67307

MRT67307 (IKKε/TBK1 Inhibitor II) inhibits IKKε and TBK1 with IC50 values of 160 nM and 19 nM at 0.1 mM ATP in vitro, but does not inhibit IKKα or IKKβ even at 10 μM. MRT67307 also is a highly potent ULK1 and ULK2 inhibitor with IC50s of 45 and 38 nM, respectively. MRT67307 can blocks autophagy in cells.
