  Regulatory molecules for the 5-HT3 receptor ion channel gating system

  摘要：

  Substituted benzoxazole derivatives which possess a nitrogen containing heterocycle at C2 are selective partial agonists of the 5-HT3 receptor. Alteration of substituents on the benzoxazole nucleus affords both agonist-like and antagonist-like compounds, and uniquely modifies the function of the 5-HT3 receptor ion channel gating system. SAR and corroborative computational docking study for these partial agonists successfully explained structure and function of the 5-HT3 receptor. (c) 2007 Elsevier Ltd. All rights reserved.

  phenylalanine with a cyclohexyl group greatly enhance potency. Several ester bioisosteres that retain potency and enantiomeric selectivity are described. Lead optimization culminated in (S)-N-[2-cyclohexyl-1-(2-pyridinyl)ethyl]-5-methyl-2-benzoxazolamine+ ++ (43b), IC50 0.001 microM. The compounds described are not inhibitors of 5-lipoxygenase but, rather, act at the level of arachidonic acid release.
