                                A structure-activity relationship (SAR) study on the benzimidazole series of opioid receptor-like 1 (ORL1) antagonists related to 1 is described. Optimization of 1 by introduction of a hydrophilic substituent into the thioether part resulted in identification of potent ORL1 antagonists with high selectivity over binding affinity for hERG and other opioid receptors.
