  摘要：

  N-[(3R)-1-Azabicyclo[2.2.2] oct-3-yl] furo[2,3-c]pyridine-5-carboxamide (14, PHA-543,613), a novel agonist of the alpha 7 neuronal nicotinic acetylcholine receptor (alpha 7 nAChR), has been identified as a potential treatment of cognitive deficits in schizophrenia. Compound 14 is a potent and selective alpha 7 nAChR agonist with an excellent in vitro profile. The compound is characterized by rapid brain penetration and high oral bioavailability in rat and demonstrates in vivo efficacy in auditory sensory gating and, in an in vivo model to assess cognitive performance, novel object recognition.
