Potent BRD9 degrader. Selectively binds BRD9 and elicits near complete degradation of BRD9 at nanomolar concentrations. Inhibits growth of synovial sarcoma cells in vitro and tumor progression in a synovial sarcoma xenograft mouse model.
Thalidomide-NH-PEG2-C2-NH-Boc, a synthesized E3 ligase ligand-linker conjugate, combines the cereblon-targeting Thalidomide ligand with a PEG linker for the synthesis of dBRD9 (compound 6). This selective BRD9 probe PROTAC degrader is utilized in researching BAF complex biology.
