Protein degradation through covalent inhibitor-based PROTACs†
Abstract
Tremendous advancements in proteolysis targeting chimera (PROTAC) technology have been made in recent years. However, whether a covalent inhibitor-based PROTAC can be developed remains controversial. Here, we successfully developed chimeric degraders based on covalent inhibitors to degrade BTK and BLK kinases, demonstrating that covalent inhibitor-based PROTACs are viable and useful tools.
