Used in epigenetic research to selectively inhibit the ATPase activity of BRM and BRG1 proteins, which are subunits of the SWI/SNF chromatin remodeling complex. This inhibition helps modulate gene expression by preventing chromatin structure changes, making it a valuable tool for studying transcriptional regulation. It is commonly applied in cellular assays to investigate the role of SWI/SNF complexes in cancer, differentiation, and cell cycle control. Its selectivity allows researchers to dissect specific pathways involved in tumor suppression and oncogenesis, supporting the development of targeted therapies for cancers with SWI/SNF mutations.
