Pomalidomide - Peg2-azide is a synthetic E3 ligand -linker conjugate containing Pomalidomide based cereblon ligand and 2-unit PEG linker. PROTAC can be synthesized to target protein degradation[1].
The IC50 value of protac compound 21[(BRD4 BD1, IC50 = 41.8 nM) composed of Pomalidomide - Peg2-azide] was 0.81 µM in inhibiting THP-1 cell line growth. At the concentration of 1 µM, compound 21 can effectively degrade BRD4 protein and inhibit c-Myc[1].
