Toolkit/molecular glues
molecular glues
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Between 2020 and 2025, major progress has been achieved across five modalities: proteolysis-targeting chimeras (PROTACs), molecular glues... Each exploits endogenous degradation or regulatory pathways using chemically engineered bifunctional or monofunctional small molecules.
Usefulness & Problems
Why this is useful
Molecular glues are presented as an induced-proximity modality that uses small molecules to engage endogenous degradation or regulatory pathways. The review compares them mechanistically and chemically with other degrader classes.; induced-proximity control of cellular processes; targeted degradation or regulatory pathway engagement
