Virtual screening of ultra-large chemical libraries is a highly effective strategy for early-stage ligand discovery. However, these pipelines often yield thousands of molecules that pass computational filters, and in silico-derived interaction energies do not consistently predict experimental efficacy. Furthermore, many high-affinity hits do not necessarily function effectively in an organism with tissues, barriers, and extensive off-target possibilities. Here, we establish and apply an...
