Used in research as a potent and selective inhibitor of bromodomain and extra-terminal (BET) proteins. It is applied in epigenetic studies to modulate gene expression, particularly in cancer research where BET proteins play a role in oncogene regulation. Shows utility in cellular assays to probe chromatin remodeling and transcriptional control. Also employed in studies related to inflammation and immune response due to its ability to suppress key inflammatory genes. Commonly used in vitro to evaluate potential therapeutic strategies in leukemia, solid tumors, and other diseases driven by dysregulated transcription.
