Tubacin is primarily used in research settings to study the role of histone deacetylase 6 (HDAC6) in cellular processes. It is a selective inhibitor of HDAC6, which makes it valuable for investigating the impact of HDAC6 on protein aggregation, cell motility, and stress responses. Researchers utilize Tubacin to explore its potential in treating diseases such as cancer, neurodegenerative disorders, and autoimmune conditions. By inhibiting HDAC6, Tubacin helps in understanding the mechanisms of protein degradation and the regulation of cellular pathways, providing insights into therapeutic strategies. Additionally, it is employed in studies focusing on the role of HDAC6 in immune system modulation and its influence on microtubule dynamics.
