New HEDGEHOG benchmark reveals limitations in AI drug discovery generators

A new benchmark called HEDGEHOG has been developed to rigorously evaluate molecular generators used in early drug discovery. This six-stage filtration process, inspired by industrial workflows, assesses compounds based on physicochemical properties, synthetic accessibility, binding affinity, and 3D pose. When applied to 23 molecular generators and over 230,000 generated molecules, HEDGEHOG found that only a small fraction, 0.65%, survived all stages. The benchmark highlights a significant limitation in current molecular generators, as compounds rarely satisfy medicinal chemistry, synthesis, docking, and 3D pose filters concurrently. AI

IMPACT Highlights a critical gap in current AI drug discovery tools, potentially guiding future model development towards more practical applications.
