TBK1/IKKε inhibitor

TBK1/IKKε signaling inhibition by MRT67307
TBK1/IKKε signaling inhibition by MRT67307

MRT67307 is a potent, reversible kinase inhibitor specifically blocking the function of TBK1 (TANK-binding kinase 1) and I-kappa-B kinase (IKK) epsilon (IKKε, or IKBKE), thereby preventing the phosphorylation of IRF3 (interferon regulatory factor 3) and subsequent expression of interferon-stimulated genes (ISGs)  [1]. Unlike BX795 from which it is derived, MRT67307 has no noted effect on the canonical IKKs, IKKα, or IKKβ, that are involved in the activation of NF-κB [1]. Additionally, MRT67307 is a highly potent inhibitor of ULK1, a key component of the autophagy pathway [2].
 

Key features:

  • MRT67307 potently inhibits IRF signaling in a dose-dependent manner.
  • MRT67307 does not affect NF-κB signaling.
  • InvitroFit™ grade: each lot is highly pure (≥95%) and functionally tested.

Inhibition of 3p-hpRNA and 2’3-cGAMP-induced responses in THP1-Dual™ Cells

2x105 THP1-Dual™ cells were transfected with 1 μg/ml 3p-hpRNA/LyoVec™ or incubated with 30 μg/ml 2’3’-cGAMP in the presence or absence of increasing concentrations of MRT67307. After overnight incubation, activation of IRF was assessed by measuring Lucia luciferase activity in the supernatant, using QUANTI-Luc™ detection reagent. Percentages of the maximal response for the ligand with no inhibitor are shown

2x105 THP1-Dual™ cells were transfected with 1 μg/ml 3p-hpRNA/LyoVec™ with or without 1 μg/ml BX795 or 3 μg/ml MRT67307. After overnight incubation, activation of IRF was assessed by measuring Lucia luciferase activity in the supernatant using QUANTI-Luc™ detection reagent. Percentages of the maximal response for the ligand with no inhibitor are shown on the left axis. The activation NF-κB was assessed by measuring SEAP activity in the supernatant using QUANTI-Blue™ Solution detection reagent. OD at 630 nm are shown on the right axis.
