3-D-QSAR/CoMFA methodology and computational simulation of ligand recognition have been successfully applied to explain the binding affinities of a series of benzimidazole derivatives 1-24 acting at serotonin 5-HT(4)Rs. Both derived computational models have facilitated the identification of the structural elements of the ligands that are key to high 5-HT4R affinity. The results provide the tools for predicting the affinity of related compounds, and for guiding the design and synthesis of new ligands with predetermined affinities and selectivity.

methods, we have studied the prototropic equilibrium present in the benzimidazole ring of a series of derivatives acting at serotonin 5-HT4 receptors. The structural study has allowed us to get insight into the bioactive conformation of the novel 5-HT4 receptor ligands which has been supported by biological data. This will help the docking of the ligands into a 3-D model of the receptor binding site
