Used in pharmaceutical research as a potent histone deacetylase (HDAC) inhibitor, particularly showing activity against cancer cell lines. It modulates gene expression by increasing histone acetylation, leading to cell cycle arrest and apoptosis in tumor cells. Investigated for its potential in treating hematological malignancies and solid tumors due to its ability to penetrate cell membranes and exert strong anti-proliferative effects. Also employed in epigenetic studies to understand chromatin remodeling and gene regulation mechanisms.
