CBP inhibitor 1 is primarily utilized in research settings to study the role of the CREB-binding protein (CBP) in various biological processes. It is employed to investigate the mechanisms of gene regulation, particularly in the context of transcriptional activation. Researchers use this compound to explore its effects on cellular pathways involved in development, differentiation, and disease states such as cancer. By inhibiting CBP, it helps in understanding the protein's contribution to epigenetic modifications and its interaction with other signaling molecules. Additionally, it serves as a tool to assess potential therapeutic strategies targeting CBP in conditions where its dysregulation is implicated.
