A series of N-substituted 9-azabicyclo[3.3.1]nonan-3alpha-yl phenylcarbamate analogs were synthesized. Among them, WC-26 and WC-59 were identified as the most potent sigma(2) receptor ligands (K(i)=2.58 and 0.82 nM, respectively) with high selectivity against sigma(1) (K(i) of sigma(1)/sigma(2) ratio=557 and 2087, respectively).
