The kinase known as IKK-β activates NF-κB signaling pathway leading to expression of several genes contributing to inflammation, immune response, and cell proliferation. Modulation of IKK-β kinase activity could be useful for treatment and management of such diseases. Starting from a discovered weakly active hit compound, twenty four thiazolidinedione-scaffold based chemical entities belonging to five series have been designed, synthesized and evaluated as potential IKK-β modulators. Among them, compounds 6q, 6r and 6u showed low micromolar IC50 values while compounds 6v, 6w, and 6x elicited submicromolar IC50 values equal to 0.4, 0.7 and 0.9 μM respectively. These submicromolar IC50 values are 243, 139 and 105 folds the value of the reported IC50 of the starting hit compound. Kinetic study of compounds 6v and 6w confirmed this class of modulators as irreversible inhibitors. LPS-treated RAW 264.7 macrophages proved the anti-inflammatory activity of compounds 6q and 6v. Assay of hERG inhibition demonstrated a safe profile of compound 6q suggesting it as a lead for further development of IKK-β modulators.

Selective kinase inhibitors development is a cumbersome task because of ATP binding sites similarities across kinases. On contrast, irreversible allosteric covalent inhibition offers opportunity to develop novel selective kinase inhibitors. Previously, we
