Used in cancer research, particularly for its potential as a histone deacetylase (HDAC) inhibitor. It shows activity against various tumor types by promoting cell cycle arrest and apoptosis in cancer cells. Studied in preclinical models for hematological malignancies and solid tumors due to its ability to alter gene expression involved in cell growth and differentiation. Its high potency and broad HDAC isoform selectivity make it a candidate for epigenetic therapy development.
