IκB / IKK inhibitors

IκB (inhibitor of κB) / IKK (IκB kinase) inhibitors are compounds that target the NF-κB signaling pathway, a key regulator of inflammation, immune response, and cell survival. In this pathway, IκB proteins bind to NF-κB transcription factors in the cytoplasm, preventing their translocation into the nucleus and subsequent activation of target genes. Upon stimulation by various signals such as cytokines or stress, IKK complexes phosphorylate IκB proteins, marking them for degradation and allowing NF-κB to translocate to the nucleus and initiate gene transcription. IκB / IKK inhibitors work by blocking IKK-mediated phosphorylation of IκB proteins, thereby inhibiting NF-κB activation and downstream inflammatory responses. These inhibitors are studied for their therapeutic potential in diseases characterized by chronic inflammation, autoimmune disorders, and certain cancers where NF-κB signaling is dysregulated.
