DUB inhibitors
DUB (deubiquitinating enzyme) inhibitors are compounds designed to inhibit the activity of deubiquitinases, a class of enzymes that reverse the process of protein ubiquitination by cleaving ubiquitin molecules from substrate proteins. Ubiquitination is a post-translational modification crucial for regulating protein stability, localization, and function within cells. DUB inhibitors interfere with this process by preventing deubiquitinases from removing ubiquitin tags, thereby leading to the accumulation of ubiquitinated proteins. This accumulation can have various cellular consequences, including altered protein degradation pathways, impaired DNA repair mechanisms, and dysregulated signaling pathways. Research into DUB inhibitors spans multiple therapeutic areas, including cancer, neurodegenerative diseases, and immune disorders, aiming to exploit the role of ubiquitination in disease mechanisms and develop targeted therapies that modulate protein turnover and cellular homeostasis for therapeutic benefit.
