Molecular glue degraders, discovered serendipitously, have opened a new field of drug discovery, attracting Big Pharma investments. These small molecules enhance protein destruction by interacting with ligases, targeting 'undruggable' proteins. Major deals in 2024 include collaborations between Biogen, Novartis, Takeda, and Novo Nordisk, potentially worth over $6 billion. The therapeutic potential spans oncology, neurodegeneration, autoimmune, and cardiometabolic diseases. The discovery of cereblon as thalidomide's target in 2010 was pivotal, leading to further research and development in this space.
