Boc-C1-PEG3-C4-OBn (PROTAC Linker 15) is a PROTAC linker characterized by its PEG composition. It can be utilized in the synthesis of various PROTACs, such as PROTAC SGK3 degrader-1 (HY-125878). PROTACs consist of two distinct ligands connected by a linker: one ligand targets an E3 ubiquitin ligase, and the other targets a specific protein. PROTACs function by leveraging the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
- Characterized by PEG composition
- Used in the synthesis of various PROTACs
- Utilizes the intracellular ubiquitin-proteasome system
- Selectively degrades target proteins
