The enantiomers of the potent σ1 receptorantagonist (±)-1 were synthesized and evaluated for their affinity at σ1, σ2 receptors and dopamine transporter (DAT). Analogously to (±)-1, both of the enantiomers showed very high affinity for the σ1 receptor and unprecedented selectivity over both the σ2 receptor and DAT. The lack of enantioselectivity between (+)-1 and (-)-1 indicated that the center of
Conservative chemical modifications of the core structure of the lead spipethiane (1) afforded novel potentσ1ligands. σ1 affinity and σ1/σ2 selectivity proved to be favored by the introduction of polar functions (oxygen atom or carbonyl group) in position 3 or 4 (4−6) or by the elongation of the distance between the two hydrophobic portions of the molecule with the simultaneous presence of a carbonyl
