Used in pharmaceutical research as a potent inhibitor of histone deacetylase enzymes (HDAC), particularly HDAC6. This compound shows promise in the development of treatments for cancer due to its ability to induce apoptosis and cell cycle arrest in tumor cells. It has also been investigated for potential applications in neurodegenerative diseases, where modulation of HDAC activity may help restore normal cellular function. Its hydroxamic acid group enables strong binding to the zinc ion in the active site of HDAC enzymes, enhancing its inhibitory effect. Due to its selectivity and potency, it serves as a valuable lead compound in drug discovery and optimization efforts.
