Bipiperidinyl compounds and salts thereof are disclosed. The compounds include high affinity ligands for σ1 receptors. Some compounds are also highly selective for σ1 receptor compared to σ2 receptor. Compounds can comprise radioisotopes, including 18F or 11C. Radiolabeled compounds can be used as probes for imaging distribution of σ1 receptor in a subject such as a human using positron emission tomography (PET) scanning.
本文披露了Bipiperidinyl化合物及其盐。这些化合物包括σ1受体的高亲和力
配体。一些化合物与σ2受体相比高度选择性地作用于σ1受体。化合物可以包含放射性同位素,包括18F或11C。放射性标记的化合物可用作探针,通过正电子发射断层扫描(PET扫描)成像研究主体(如人体)中σ1受体的分布。
