This chemical is primarily used in the development of PROTACs (Proteolysis Targeting Chimeras), which are innovative molecules designed to target and degrade specific proteins within cells. Its structure allows it to serve as a linker, connecting the target protein-binding moiety to the E3 ubiquitin ligase-binding moiety, facilitating the ubiquitination and subsequent degradation of the target protein. This application is particularly valuable in drug discovery and therapeutic research, especially for targeting proteins that are traditionally considered "undruggable." It is also utilized in chemical biology studies to explore protein function and signaling pathways, aiding in the understanding of disease mechanisms and the development of novel treatments.
