GtoPdb Ligand ID: 11588

Compound class: Synthetic organic
Comment: Compound 17 is an alectinib-based PROTAC degrader of anaplastic lymphoma kinase (ALK) [1]. The alectinib analogue is conjugated to pomalidomide through a linker, to deliver ALK protein for degradation via the ubiquitously expressed E3 ligase receptor cereblon. Compound 17 is one of the chemical structures claimed in ShanghaiTech University's patent WO2019114770A1 [2].
