CAY10594 (Cat No.: R064367) is a small-molecule inhibitor of TANK-binding kinase 1 (TBK1), a serine/threonine kinase that regulates innate immune signaling and interferon production. By blocking TBK1 activity, CAY10594 suppresses phosphorylation of IRF3 and downstream type I interferon responses. It is widely used as a research tool to study TBK1-dependent pathways in antiviral defense, inflammation, and cancer. Given TBK1’s involvement in autoimmunity and tumorigenesis, CAY10594 provides insights into therapeutic strategies aimed at modulating immune checkpoints and inflammatory signaling cascades.
