Thalidomide fluoride (Cereblon ligand 4) is the Thalidomide-based Cereblon ligand used in the recruitment of CRBN protein. Thalidomide fluoride (Cereblon ligand 4) can be connected to the ligand for IRAK4 protein by a linker to form PROTAC IRAK4 degrader-1.
BC-1215 is an inhibitor of F-box protein 3 (FBXO3, a ubiquitin E3 ligase component, IC50=0.9 μg/mL for IL-1β release). BC-1215 decreases Fbxo3-Fbxl2 interaction and prevents SCFFbxo3 catalyzed Fbxl2 ubiquitination.
