Used in epigenetic research as a potent inhibitor of histone deacetylases (HDACs), Trapoxin A helps study gene expression regulation by preventing histone deacetylation. It is valued in cancer research for its ability to induce cell cycle arrest and apoptosis in tumor cells. Due to its stability and specificity, it serves as a tool compound for validating HDAC-targeted therapies and understanding chromatin remodeling mechanisms.
