Here, we explored large library docking for joint activity against target pairs. Retrospectively, as libraries grew, so too did the number of likely dual-activity molecules. In prospective docking of a 900-million molecule library against three target pairs (α/SERT, MOR/SERT, and α/MOR), we sought analgesic compounds. Both the α/SERT and SERT/MOR campaigns led to dual binders with low μM to high nM activities with high hit rates; tetrahydropyridines from the α/SERT campaign were also active against 5-HT. However, even though cryo-EM structures confirmed the docking-predicted poses, optimization struggled to improve potency. Still, in mouse behavioral assays, the most potent α/SERT compound (') was effective against pain without inducing conditioned place preference, and the molecule had potent antidepression and anxiolytic drug-like behavior, consistent with its SERT/5-HT activities. This study reveals both advantages and challenges of docking for polypharmacology. | ||||||||||||||||||||||||
