title: Pharmacophore identification for sigma-1 (sigma1) receptor binding: application of the "deconstruction-reconstruction-elaboration" approach.
abstract: At least two different types of sigma (sigma1 and sigma2) receptors have been identified. A structural feature common to high-affinity (Ki <10 nM) sigma1 ligands is: C-N(R)-X-Ph; both C and Ph are associated with regions of bulk tolerance. Numerous other ligands bind, but typically do so with lower affinity.
