IKK-16 is a selective IκB kinase (IKK) inhibitor for IKK-2, IKK complex and IKK-1 with IC50 of 40 nM, 70 nM and 200 nM in cell-free assays, respectively.

Sodium salicylate(水杨酸钠) is used in medicine as an analgesic and antipyretic.

Ammonium pyrrolidine dithiocarbamate(吡咯烷二硫代甲酸铵盐) is a potent nuclear factor-κB (NF-κB) inhibitor that inhibits IκB phosphorylation, blocks NF-κB translocation to the nucleus and reduces the  of downstream cytokines.  

Cardamonin is a naturally occurring chalcone with strong anti-inflammatory activity. It is a novel TRPA1 antagonist with IC50 of 454 nM and also a NF-kB inhibitor.

Curcumenol(莪术烯醇), a sesquiterpene isolated from Curcuma zedoaria, is known to possess a variety of health and medicinal values which includes neuroprotection, anti-inflammatory, anti-tumor and hepatoprotective activities. It inhibits NF-κB activation by suppressing the nuclear translocation of the NF-κB p65 subunit and blocking IκBα phosphorylation and degradation.

Sodium 4-Aminosalicylate(4-氨基水杨酸钠二水合物) is an antibiotic used to treat tuberculosis via NF-κB inhibition and free radical scavenging.

SC-514 is an orally active, ATP-competitive IKK-2 inhibitor with IC50 of 3-12 μM, blocks NF-κB-dependent gene , does not inhibit other IKK isoforms or other serine-threonine and tyrosine kinases.
