摘要

The present invention related to the ±7-selective ligand (2S,3R)-N-(2-((3-pyridinyl)methyl)-l-azabicyclo[2.2.2]oct-3-yl)-5-methylthiophene-2-carboxamide or a pharmaceutical acceptable salt thereof and (2S,3R)-N-(2-((3-pyridinyl)methyl)-1-azabicyclo[2.2.2]oct-3-yl)-5-methylthiophene-2-carboxamide or a pharmaceutical acceptable salt thereof, substantially free of (2R,3R)-N-(2-((3-pyridinyl)methyl)-1-azabicyclo[2.2.2]oct-3-yl)-5-methylthiophene-2-carboxamide or a pharmaceutical acceptable salt thereof, (2S,3S)-N-(2-((3-pyridinyl)methyl)-1-azabicyclo[2.2.2]oct-3-yl)-5-methylthiophene-2-carboxamide or a pharmaceutical acceptable salt thereof and (2R,3S)-N-(2-((3-pyridinyl)methyl)-1-azabicyclo[2.2.2]oct-3-yl)-5-methylthiophene -2-carboxamide or a pharmaceutical acceptable salt thereof.
