SN50 is primarily used in research and biomedical applications due to its ability to inhibit the nuclear factor kappa B (NF-κB) signaling pathway. This pathway plays a critical role in regulating immune responses, inflammation, and cell survival. By blocking NF-κB activation, it helps researchers study the effects of inflammation and immune responses in various diseases, such as cancer, autoimmune disorders, and chronic inflammatory conditions. It is also utilized in experimental settings to investigate potential therapeutic strategies for conditions where NF-κB activation is implicated. Its application is largely confined to laboratory studies and preclinical research.
