Identification of Selective IKZF2 Degraders That Reprogram Suppressive Regulatory T Cells in Solid Tumors
Targeted protein degradation (TPD) using the endogenous Ubiquitin Proteasome System (UPS) is a rapidly growing drug discovery strategy to eliminate pathogenic proteins. Molecular glues are small molecules that promote a novel interaction between a protein of interest with an E3 ubiquitin ligase leading to proximity induced protein degradation. This has enabled targeting undruggable proteins, such as the zinc-finger transcription factor Helios (IKZF2), that have no known small molecule binding pocket…
