This compound is widely utilized in the field of targeted protein degradation, particularly in the development of PROTACs (Proteolysis Targeting Chimeras). Its structure allows it to effectively bind to E3 ubiquitin ligase, facilitating the degradation of specific proteins of interest. This application is crucial in research focused on understanding disease mechanisms, especially in cancer, where it helps in the selective elimination of oncogenic proteins. Additionally, it is employed in the study of protein function and regulation, providing insights into cellular processes and potential therapeutic targets. Its PEG3 linker enhances solubility and stability, making it suitable for various biochemical and cellular assays.
