STING-IN-4 (Cat No.: I042456) is a potent small-molecule inhibitor of STING (Stimulator of Interferon Genes), a key adaptor protein in the innate immune response that mediates type I interferon production upon cytosolic DNA sensing. By inhibiting STING activation, STING-IN-4 modulates downstream signaling pathways such as TBK1-IRF3 and NF-κB, reducing pro-inflammatory cytokine release. It is a valuable tool for studying STING-related autoimmune and inflammatory diseases, including lupus and autoinflammatory syndromes. STING-IN-4 supports therapeutic exploration in conditions involving dysregulated innate immune activation.
