FKBP12 PROTAC RC32, also known as RC32, is a powerful FKBP12 degrader developed using PROTAC (Proteolysis Targeting Chimera) technology. RC32 combines two key components: Rapamycin (HY-10219), which serves as the ligand for FKBP12, and Pomalidomide (HY-10984), which acts as the ligand for an E3 ubiquitin ligase. This design allows RC32 to recruit the E3 ubiquitin ligase to FKBP12, leading to the targeted ubiquitination and subsequent degradation of FKBP12. RC32 demonstrates potential as a novel therapeutic approach for diseases where FKBP12 plays a critical role.
