IKKβ-IN-5

IKKβ-IN-5 is an orally active and selective IKKβ inhibitor with an IC₅₀ of 7.5 nM. IKKβ-IN-5 directly inhibits IKKβ phosphorylation and attenuates NF κB mediated inflammatory and survival signals while promoting autophagy flux. IKKβ-IN-5 exhibits a 6-fold selectivity forIKKβ over the homologous kinase IKKα. IKKβ-IN-5 exerts robust antiproliferative effects through a dual mechanism involving G₂/M phase cell cycle arrest and autophagy activation, even under inflammatory stimulation in vitro. IKKβ-IN-5 demonstrates favorable pharmacokinetics and suppresses tumor growth in vivo. IKKβ-IN-5 can be used for colorectal cancer and potentially other inflammation driven malignancies research.
