FUBP1–IN-1 is primarily used in research settings to study its role as an inhibitor of Far Upstream Element-Binding Protein 1 (FUBP1). This protein is involved in regulating gene expression, particularly in cancer cells. By inhibiting FUBP1, researchers aim to understand its impact on cancer cell proliferation and survival. This compound is valuable in exploring potential therapeutic strategies for cancers where FUBP1 is overexpressed or dysregulated. It is also utilized in biochemical assays to investigate the molecular pathways and mechanisms controlled by FUBP1, contributing to the development of targeted cancer therapies.
