Abstract
The present invention relates to diazabicyclic compounds, and preferably N-aryl diazabicyclic compounds. Of particular interest are 2-pyridyl diazabicyclic compounds, such as (1S,4S)-2-(3-pyridyl)-2,5-diazabicyclo[2.2.1]heptane. Other exemplary compounds of the present invention include: (1S,4S)-2-(5-(4-methoxyphenoxy)-3-pyridyl)-2,5-diazabicyclo[2.2.1]heptane, (1S,4S)-2-(5-pyrimidinyl)-2,5-diazabicyclo[2.2.1]heptane and (1S,4S)-2-(6-chloro-3-pyridazinyl)-2,5-diazabicyclo[2.2.1]heptane. The present invention also relates to prodrug derivatives of the compounds of the present invention.
