SC75741 is primarily used in research settings as a potent inhibitor of NF-κB activation. It is particularly valuable in studying inflammatory pathways and immune responses, as NF-κB plays a critical role in regulating these processes. Researchers utilize SC75741 to investigate its effects on various diseases, including cancer, autoimmune disorders, and chronic inflammatory conditions. By blocking NF-κB signaling, it helps elucidate the molecular mechanisms underlying these diseases and aids in the development of potential therapeutic strategies. Additionally, SC75741 is employed in preclinical studies to assess its efficacy and safety as a candidate for anti-inflammatory or anti-cancer treatments.
