Structure-activity studies on benzimidazole lead 1 obtained from library screening led to the discovery of potent and selective ORL1 antagonist 28, 5-chloro-2-[(1-ethyl-1-methylpropyl) thio]-6-[4-(2-hydroxyethyl) piperazin-1-yl]-1H-benzimidazole, which is structurally distinct from conventional non-peptide antagonists known to date.
