target protein-binding moiety

Ibrutinib (PCI-32765) is an irreversible inhibitor of BTK (IC50: 0.5 nM) that selectively blocks B cell activation.

Quizartinib (AC220) is an inhibitor of FLT3 (Kd: 1.6 nM) and demonstrates high selectivity for FLT3 when tested against a panel of 227 additional kinases.

(+)-JQ-1 (JQ1) is a specific, reversible BET bromine domain inhibitor that targets BRD4 (1/2) with IC50 values of 77/33 nM. (+)-JQ-1 induces cell autophagy and inhibits cell proliferation.

AR antagonist 1 is a potent antagonist of the androgen receptor. It binds to E3 ligase ligands with weak binding affinities to VHL protein in the synthesis of PROTAC ARD-266.

Navitoclax-piperazine (ABT-263-piperazine) is a B-cell lymphoma extra large (BCL-XL) inhibitor.

Desmorpholinyl Navitoclax-NH-Me (Desmorpholinyl ABT-263-NH-Me) is a Bcl-xL inhibitor, which can be employed alongside a CRBN ligand to synthesize XZ739, a PROTAC BCL-XL degrader [1] [2].

BI-4464 is a highly selective inhibitor targeting focal adhesion kinase (FAK). BI-4464 effectively blocks the catalytic activity of FAK by competitively binding to the ATP-binding site, with an IC₅₀ of 17 nM. In addition to its role as a kinase inhibitor, BI-4464 can also serve as a FAK-targeting ligand (warhead) for PROTAC design. By conjugation with an E3 ligase ligand via an appropriate linker, the resulting PROTAC molecule can induce the selective degradation of FAK through the ubiquitin–proteasome pathway, providing a valuable tool for cancer biology and related disease research.

DUPA (N,N''-Carbonylbis[L-glutamic acid]) is used as the targeting moiety to actively deliver DTX for treatment of Prostate-Specific Membrane Antigen (PSMA) expressing prostate cancer.

SLF-amido-C2-COOH (ZZY01-083) is an FKBP ligand with potential antimicrobial activity for the synthesis of PROTAC.

Dasatinib carbaldehyde (PROTAC ABL binding moiety 4) is based on Dasatinib which is an ABL inhibitor, binds to the IAP ligand via a linker, and forms SNIPER [1].

PROTAC FKBP Degrader-3 is a bifunctional PROTAC molecule composed of an FKBP ligand-binding group, a rationally designed linker, and a VHL E3 ligase-binding moiety, and functions as a potent FKBP degrader, enabling selective protein degradation studies and validation of FKBP as a therapeutic target.
