  Novel ORL1-selective antagonists with oral bioavailability and brain penetrability

  摘要：

  Following the discovery of 5-chloro-6-[piperazin-1-yl]-1H-benzimidazole as a novel pharmacophore for potent and selective ORL1 antagonist activity, optimization of this new lead by introduction of a methyl substitution on the piperazine ring resulted in a highly potent and selective, orally available, and brain penetrable ORL1 antagonist, 2-(tert-butylthio)-5-chloro-6-[(2R)-4-(2-hydroxyethyl)-2-methylpiperazin-1-yl]-1 H-benzimidazole. Stereochemistry of the methyl substituent on the piperazine ring to control the functional activity of other opioid receptors is also described. (C) 2008 Elsevier Ltd. All rights reserved.
