Here we report the development of a proteolysis targeting chimera (PROTAC) based on the combination of the unique features of the sirtuin rearranging ligands (SirReals) as highly potent and isotype-selective Sirt2 inhibitors with thalidomide, a bona fide cereblon ligand. For the first time, we report the formation of a PROTAC by Cu(I)-catalyzed cycloaddition of a thalidomide-derived azide to an alkynylated inhibitor. This thalidomide-derived azide as well as the highly versatile linking strategy can be readily adapted to alkynylated ligands of other targets. In HeLa cells, our SirReal-based PROTAC induced isotype-selective Sirt2 degradation that results in the hyperacetylation of the microtubule network coupled with enhanced process elongation. Thus, our SirReal-based PROTAC is the first example of a probe that is able to chemically induce the degradation of an epigenetic eraser protein.
