Structure–Activity Studies of Diazabicyclo[3.3.0]octane-Substituted Pyrazines and Pyridines as Potent α4β2 Nicotinic Acetylcholine Receptor Ligands
摘要:
A series of diazabicyclo[3.3.0]octane substituted pyridines and pyrazines was synthesized and characterized at the alpha 4 beta 2 neuronal nicotinic acetylcholine receptor (nAChR). The compounds were designed to mimic the profile of ABT-089, high affinity binding ligand for the alpha 4 beta 2 nAChR, with limited agonist activity. Carboxamide derivatives of 3-(diazabicyclo[3.3.0]octane)-substituted pyridines or 2-(diazabicyclo[3.3.0]octane)-substituted pyrazines were found to have the desired binding and activity profile. The structure-activity relationship of these compounds is presented.
