NF-κB inducing kinase is a therapeutic target for systemic lupus erythematosus.

NF-κB-inducing kinase (NIK) mediates non-canonical NF-κB signaling downstream of multiple TNF family members, including BAFF, TWEAK, CD40, and OX40, which are implicated in the pathogenesis of systemic lupus erythematosus (SLE). Here, we show that experimental lupus in NZB/W F1 mice can be treated with a highly selective and potent NIK small molecule inhibitor. Both in vitro as well as in vivo, NIK inhibition recapitulates the pharmacological effects of BAFF blockade, which is clinically efficacious in SLE.

Thermodynamic profiling of inhibitors of Nrf2:Keap1 interactions.

Keap1 binds to the transcription factor Nrf2 and negatively modulates the expression of genes involved in cellular protection against oxidative stress. Small molecules have been discovered to inhibit the Nrf2:Keap1 interactions and act as antagonists of Keap1. The affinities of these small molecules are not very high and need further improvement in follow up hit-to-lead programs.
