(S,R,S)-AHPC-PEG2-NH2 dihydrochloride is primarily utilized in the field of targeted protein degradation. It serves as a key component in the development of PROTACs (Proteolysis Targeting Chimeras), which are designed to selectively degrade disease-causing proteins. This compound is particularly effective in facilitating the recruitment of E3 ubiquitin ligases to specific target proteins, marking them for degradation by the proteasome. Its application is significant in cancer research, where it helps in the degradation of oncogenic proteins, potentially offering a novel therapeutic strategy. Additionally, it is used in biochemical studies to explore protein function and regulation, providing insights into cellular processes and disease mechanisms.
