KB02-JQ1 is a highly selective and PROTAC-based BRD4 degrader (molecular glue), but does not degrade BRD2 or BRD3. KB02-JQ1 promotes BRD4 degradation by covalently modifying DCAF16 (E3 ligase) and can improve the durability of protein degradation in biological systems. JQ1 binds ubiquitin E3 ligase ligand KB02 via a linker to form KB02-JQ1.

Halo PROTAC 1 is a PROTAC, which is a ligand having activity to bind to an intracellular proteins fused with HaloTag and a structure having activity to induce autophagy of an intracellular molecule are linked via a PEG linker.

KB02-SLF is a PROTAC-based nuclear FKBP12 degrader (molecular glue). KB02-SLF promotes nuclear FKBP12 degradation by covalently modifying DCAF16 (E3 ligase) and can improve the durability of protein degradation in biological systems. SLF binds ubiquitin E3 ligase ligand KB02 via a linker to form KB02-SLF.

SIAIS178 is a potent and selective BCR-ABL degrader based on PROTAC technology with an IC50 of 24 nM. SIAIS178 causes effective degradation of BCR-ABL protein by recruiting Von Hippel-Lindau (VHL) E3 ubiquitin ligase. SIAIS178 has anticancer activity.

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.

MD-224 is a first-in-class and highly potent small-molecule human murine double minute 2 (MDM2) degrader based on the proteolysistargeting chimera (PROTAC) concept. MD-224 induces rapid degradation of MDM2 at concentrations <1 nM in human leukemia cells, and achieves an IC50 value of 1.5 nM in inhibition of growth of RS4;11 cells. MD-224 has the potential to be a new class of anticancer agent.
