GtoPdb Ligand ID: 10531

Compound class: Synthetic organic
Comment: BSJ-04-132 is a PROTAC (proteolysis targeting chimera) [1]. It is a hybrid molecule that simultaneously inhibits CDK4/CDK6 kinase activity and recruits E3 ligase CRL4CRBN to target kinase protein destruction via E3 ligase-mediated ubiquitination and proteasomal degradation. BSJ-04-132 is a ribociclib-based degrader that selectively degrades CDK4.
