KB02-SLF is a PROTAC-based nuclear FKBP12 degrader, known as a molecular glue. It facilitates the degradation of nuclear FKBP12 by covalently modifying DCAF16, an E3 ligase. Moreover, KB02-SLF enhances the longevity of protein degradation in biological systems. The compound SLF acts as a linker, binding to the ubiquitin E3 ligase ligand KB02, resulting in the formation of KB02-SLF[1].
FKBP12 PROTAC dTAG-7 (dTAG-7) is a heterobifunctional compound that selectively degrades the BET bromodomain transcriptional co-activator BRD4 by connecting BET bromodomains to the E3 ubiquitin ligase CRBN. Additionally, it serves as a degrader of FKBP12F36V when FKBP12F36V is expressed in-frame with a targeted protein.
ILS-920 is a Rapamycin analog characterized by diminished immunosuppressive effects but remarkable neuroprotective properties. It exhibits selective binding affinity towards the immunophilin FKBP52 as well as the β1-subunit of L-type voltage-gated calcium channels (VGCC). ILS-920 displays a notable 200-fold preference for FKBP52 over FKBP12.
dFKBP-1 is a potent and PROTAC-based FKBP12 degrader. dFKBP-1 incorporates the ligand SLF of FKBP12, the Thalidomide based cereblon ligand and a linker[1].
AP1867-2-(carboxymethoxy), a moiety based on the synthetic FKBP12F36V-directed ligand AP1867, connects to the CRBN ligand through a linker to generate dTAG molecules[1].
