Molecular Glues (分子胶)

Protein degradation agents based on the ubiquitin-proteasome pathway include a part of molecular glues. Molecular glues are a class of small molecule compounds that can induce or stabilize the interaction between proteins. If one of the protein is ubiquitin ligase, molecular glue can cause another protein to undergo ubiquitin modification and degradation through the proteasome pathway, which is similar to PROTAC. However, these molecules are classified as ligand for E3 ligase as functional molecules in subsequent classification. Older drugs, thalidomide, lenalidomide, and pomalidomide, together with CC-90009 and CC-92480 reported later all belong to this category.
