PROTAC Bcl-xL degrader-2（Cat No.:I044423）is a bifunctional molecule designed to selectively degrade the anti-apoptotic protein Bcl-xL via the ubiquitin-proteasome system. It consists of a Bcl-xL ligand linked to an E3 ligase recruiter, typically targeting VHL or CRBN, enabling proximity-induced ubiquitination and proteasomal degradation of Bcl-xL. This PROTAC circumvents the dose-limiting platelet toxicity associated with direct Bcl-xL inhibitors by offering cell-type selectivity. It is a valuable tool in cancer research, particularly in hematologic malignancies and solid tumors dependent on Bcl-xL for survival, supporting the development of targeted protein degradation therapies.
