Used in targeted protein degradation, it serves as a key component in PROTAC (Proteolysis Targeting Chimeras) molecules. It binds to E3 ubiquitin ligase, facilitating the degradation of specific proteins involved in disease pathways. This makes it valuable in research for treating cancers, neurodegenerative disorders, and other conditions driven by abnormal protein expression. Its application extends to drug discovery, where it helps study protein function and validate therapeutic targets.
