Used in research as a potent and selective inhibitor of the enzyme TANK-binding kinase 1 (TBK1), which plays a key role in innate immune signaling pathways. It is primarily applied in studies related to inflammation, antiviral responses, and cancer immunology. The compound helps modulate signaling through the STING and NF-κB pathways, making it a valuable tool for investigating autoimmune diseases and tumor microenvironment regulation. It has also been explored in preclinical models to assess the therapeutic potential of TBK1 inhibition in oncology and chronic inflammatory conditions.
