NIK SMI1 is a potent, selective small molecule inhibitor of NF-κB inducing kinase (NIK) with Ki of 230±170 pM; only inhibits 3 out of 222 off-target kinases (KHS1, LRRK2, and PKD1) with >75% inhibition at 1 uM; potently inhibits anti-LTβR-induced nuclear p52 levels in anti-LTβR-stimulated HeLa cells, with no effect on canonical signaling; inhibits BAFF and CD40 signaling, suppresses immune responses in vivo; suppresses disease biomarkers and improves survival and renal function in NZB/W F1 mice.
