PROTAC IRAK4 degrader-1 is a PROTAC interleukin-1 receptor-associated kinase 4 (IRAK4) degrader extracted from patent US20190192668A1 Compound I-210, makes <20%, >20-50%, and >50% IRAK4 degradation at 0.01, 0.1, and 1 μM in OCI-LY-10 cells, respectively.

GNE-987 is a highly active chimeric BET degrader. GNE-987 exhibits picomolar cell BRD4 degradation activity (DC50=0.03 nM for EOL-1 AML cell line). GNE-987 binds equipotently to the BD1 and BD2 bromodomains of BRD4 with low nanomolar affinities (IC50=4.7 and 4.4 nM, respectively). GNE-987 incorporates a potent BET binder/inhibitor, a VHL-binding fragment, and a ten methylene spacer moiety. GNE-987 can be used in PROTAC-Antibody Conjugate (PAC).

(S)-GNE-987 (compound 4), the GNE-987 (a chimeric BET degrader) hydroxy-proline epimer, abrogates binding to VHL and does not degrade BRD4 protein. (S)-GNE-987 binds to the BRD4 BD1(IC50=4 nM) and BD2 (3.9 nM) bromodomains and can be used to design PROTAC-Antibody Conjugate (PAC).

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.

XY028-133 (example 14) is a PROTAC-based CDK4/6 degrader with anti-tumor activity, extracted from patent WO2018106870A1.

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.

SNIPER(ABL)-062 is a novel, potent SNIPER molecule that tethers BCR-ABL inhibitor to a ligand of IAP, causes potent BCR-ABL degradation.

QCA570 is a novel, highly potent efficacious BET degrader (PROTAC).

HDAC6 degrader 9c (dHDAC6 9c) is a bifunctional molecule (dHDAC6) that could selectively degrade HDAC6, by conjugating non-selective HDAC inhibitor to a thalidomide-type E3 ligase ligand.

BTK PROTAC 9 is a novel potent PROTAC for BTK with DC50 of 5.9 nM in cultured Ramos cells, requires simultaneous engagement of BTK and CRBN to effectively degrade BTK.

BTK PROTAC 10 is a novel potent PROTAC for BTK with DC50 of 1.1 nM in cultured Ramos cells.
