SNIPER

"IAPs can inhibit apoptosis by inhibiting caspase, and also exhibits the activity of E3 ubiquitin ligase. Specific and nongenetic IAP-based protein erasers (SNIPERs) are hybrid molecules that designed based on IAPs, and used to degrade the target proteins closely associated with diseases. SNIPERs (PROTACs) degrade diseases-associated proteins through human inherent ubiquitin-proteasome system. So far, many SNIPERs have been developed to treat diseases that difficult to handle by traditional methods, such as radiotherapy, chemotherapy and small molecule inhibitors, and showed promising prospects in application.

PROTACs/SNIPERs are composed of three parts, including a ligand for target protein, a ligand for E3 ligase and a linker between them. All three parts are crucial for protein degradation activity of PROTACs/SNIPERs. In recent years, PROTACs (SNIPERs) have been universally used as inducers to degrade many target proteins, such as AR, ER, Era and etc."
