GtoPdb Ligand ID: 9964

Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: NIK SMI1 is a selective inhibitor of the NF-κB-inducing kinase, NIK (MAP3K14) [1]. NIK is a kinase that operates downstream of several TNF family receptors, including BAFF (TNFRSF13C), TWEAK (TNFRSF12A), CD40 (TNFRSF5), and OX40 (TNFRSF4), and which mediates non-canonical NF-κB signaling. Inhibition of NIK recapitulates the inhibition of BAFF that is observed for example using the anti-BAFF, SLE approved biologic belimumab. The compound has no effect on canonical NF-κB signaling.

Bioactivity Comments
In a screening panel NIK SMI1 inhibited just 3 off-target kinases, KHS1 (MAP4K5), LRRK2, and PKD1 (PRKD1), by >75% at 1 μM, out of 222 kinases tested. Ki determination established NIK SMI1's selectivity over these off-targets [1].
