GtoPdb Ligand ID: 11785

Synonyms: compound 23 [PMID: 32803978]
Compound class: Synthetic organic
Comment: This molecule is aproteolysis-targeting chimera (PROTAC) degrader of interleukin 1 receptor associated kinase 3 (IRAK3) [1]. It promotes ternary complex formation between IRAK3 and the cereblon (CRBN) E3 ubiquitin ligase. IRAK3 is a regulatory protein that suppresses proinflammatory signalling in monocytes, macrophages, and neutrophils. Blocking IRAK3's immunosuppressive function is being investigated as an anti-tumour mechanism [2].
