Emerging from Johns Hopkins professor Jun O. Liu’s laboratory, Rapafusyn Pharmaceuticals develops non-degrading molecular-glue medicines designed to reach hard-to-drug intracellular and transmembrane targets. Based on its RapaGlue™ platform, the Baltimore biotech is advancing an early pipeline that includes an ENT1 inhibitor for acute kidney injury, an area where the company says no approved preventive therapies exist. Its discovery engine combines AI-enabled machine learning with a DNA-encoded library containing more than 8 billion non-degrading glues.
