This compound is primarily used in biochemical research to study the role of HDAC6, a specific histone deacetylase enzyme, in cellular processes. It serves as a potent and selective inhibitor of HDAC6, making it valuable for investigating its function in diseases like cancer, neurodegenerative disorders, and inflammatory conditions. Researchers utilize it to explore how HDAC6 inhibition affects protein acetylation, cellular signaling pathways, and disease progression. Its selectivity allows for targeted studies without significantly impacting other HDAC isoforms, providing insights into potential therapeutic strategies. Additionally, it is employed in drug discovery efforts to develop HDAC6-specific inhibitors for clinical applications.
