DUBs inhibitor 1 is primarily used in research to study the role of deubiquitinating enzymes (DUBs) in cellular processes. It helps in understanding protein degradation pathways, particularly in the ubiquitin-proteasome system. This inhibitor is valuable in cancer research, as it can be used to explore how DUBs influence tumor growth and survival. Additionally, it aids in identifying potential therapeutic targets for diseases where DUB activity is dysregulated, such as neurodegenerative disorders and immune-related conditions. Its application extends to drug discovery, where it serves as a tool to screen and develop new DUB-targeting compounds.
