Abstract: In recent years, the role of inhibitor kappa B kinaseβ (IKKβ) in the process of tumorigenesis has gradually been elucidated. IKK is involved in tumor cell proliferation and survival by acting on multiple molecular pathways. Inhibition of IKKβ has been identified as a promising treatment for cancer. Researchers have developed a series of IKKβ inhibitors and found that they can effectively inhibit tumor growth, but no IKKβ inhibitors have been used clinically to treat cancer. We discuss progress in understanding the role of IKKβ in tumorigenesis and review the recent development of main inhibitors of IKKβ.

Key words: inhibitor kappa B kinaseβ, inhibitor kappa B kinaseβ inhibitors, tumorigenesis
