GtoPdb Ligand ID: 10529

Compound class: Synthetic organic
Comment: TL13-112 is a PROTAC (proteolysis targeting chimera) [1]. It is a hybrid molecule that simultaneously inhibits ALK kinase activity and recruits E3 ligase CRL4CRBN to target ALK for destruction via E3 ligase-mediated ubiquitination and proteasomal degradation. The ALK targeting function is based on the ALK inhibitor NVP-TAE684, and the cereblon ligand component is derived from pomalidomide.
