Ligands for cereblon: 2017–2021 patent overview

The chemical space of CRBN ligands which is related to the classical IMiDs (thalidomide/lenalidomide/pomalidomide) is comprehensively covered by the current patent literature. The promising area of research is in the identification of non-thalidomide-like chemotypes capable of binding to CRBN. Rational, crystallography-driven approaches currently exploited in academia will significantly aid in this endeavor.
