Used primarily in biochemical and biomedical research as a potent histone deacetylase (HDAC) inhibitor. It modulates gene expression by increasing histone acetylation, making it a valuable tool in studying epigenetic regulation. Commonly applied in cancer research due to its ability to induce cell cycle arrest, differentiation, and apoptosis in various tumor cell lines. Also utilized in studies related to inflammation, neurodegenerative diseases, and cardiac hypertrophy because of its regulatory effects on non-histone proteins involved in signaling pathways. Its cell permeability and stability make it suitable for in vitro and in vivo experimental models.
