Used in immunology and oncology research to modulate the STING (stimulator of interferon genes) pathway, C-178 helps suppress excessive immune activation. It is applied in studies involving autoimmune diseases, chronic inflammation, and cytokine storms where uncontrolled STING signaling contributes to pathology. By inhibiting this pathway, C-178 allows researchers to dissect immune responses and evaluate therapeutic strategies for conditions driven by aberrant interferon production. It also serves as a tool compound in cancer immunotherapy research, helping to understand how STING modulation affects tumor microenvironments and response to treatments.
