MC1568 is primarily utilized in the field of biomedical research as a selective inhibitor of class II histone deacetylases (HDACs), particularly HDAC4 and HDAC6. Its application is significant in studying epigenetic regulation and cellular processes such as differentiation, proliferation, and apoptosis. Researchers employ MC1568 to investigate the role of HDACs in various diseases, including cancer, neurodegenerative disorders, and inflammatory conditions. It is also used to explore potential therapeutic strategies by modulating gene expression and protein function through HDAC inhibition. Additionally, MC1568 aids in understanding the mechanisms of chromatin remodeling and its impact on cellular behavior, providing insights into targeted drug development.
