Here, we develop an empirical energy function based on quantum mechanical data for the interaction between methane and benzene that captures the contribution from CH−π interactions. Such interactions are frequently observed in protein–ligand crystal structures, particularly for carbohydrate ligands, but have been hard to quantify due to the absence of a model for CH−π interactions in typical molecular mechanical force fields or docking scoring functions. The CH−π term was added to the AutoDock Vina (AD VINA) scoring function enabling its performance to be evaluated against a cohort of more than 1600 occurrences in 496 experimental structures of protein–ligand complexes. By employing a conformational grid search algorithm, inclusion of the CH−π term was shown to improve the prediction of the preferred orientation of flexible ligands in protein-binding sites and to enhance the detection of carbohydrate-binding sites that display CH−π interactions. Last but not least, this term was also shown to improve docking performance for the CASF-2016 benchmark set and a carbohydrate set.
