PROTACARDegrader-4包含cIAP1配体结合基团,linker和雄激素受体(AR)配体结合基团。基于cIAP1的降解剂也被称为SNIPER。
PROTAC AR Degrader-4 comprises a cIAP1 ligand binding group, a linker and an androgen receptor (AR) binding group. PROTAC AR Degrader-4 is an AR degrader. Degradation inducers based on cIAP1 are called specific and non-genetic IAP-dependent protein erasers (SNIPERs)[1].
Specific and Nongenetic IAPs-dependent Protein Erasers (SNIPERs) are bifunctional compounds which are designed by conjugating an IAPs-recognition structure with a target protein-recognition structure. Targeting proteins for degradation involves three steps. 1, its two recognition structures allow SNIPER to form a complex linking IAPs, which have E3 ligase activity, with the target protein. 2, the target protein is polyubiquitinated by IAPs. 3, the polyubiquitinated protein is degraded by proteasome.
