Bipiperidinyl compounds and salts thereof are disclosed. The compounds include high affinity ligands for σ
1
receptors. Some compounds are also highly selective for σ
1
receptor compared to σ
2
receptor. Compounds can comprise radioisotopes, including
18
F or
11
C. Radiolabeled compounds can be used as probes for imaging distribution of σ
1
receptor in a subject such as a human using positron emission tomography (PET) scanning.
双哌啶基化合物及其盐被披露。这些化合物包括对σ1受体具有高亲和力的配体。一些化合物相对于σ2受体也具有高选择性。化合物可以包含放射性同位素,包括18F或11C。放射标记的化合物可用作探针,用于通过正电子发射断层扫描(PET扫描)在受试者(如人类)中成像σ1受体的分布。
