Rimonabant with high binding affinity for the cerebral cannabinoid receptor (CB1) and with optimized lipophilicity have been synthesized as potential positron emission tomography (PET) ligands. The best ligands of the series are optimal targets for the future radiolabeling with PET isotopes and in vivo evaluation as radioligands with enhanced properties for PET imaging of CB1 receptors in human subjects.

已经合成了对脑大麻素受体 (CB1) 具有高结合亲和力并具有优化的亲脂性的利莫那班氰基类似物,作为潜在的正电子发射断层扫描 (PET) 配体。该系列中最好的配体是未来用 PET 同位素进行放射性标记和体内评估作为具有增强的人类受试者 CB1 受体 PET 成像特性的放射性配体的最佳目标。啮齿动物脑切片的细胞外电生理记录表明,新系列的先导化合物JHU75528, 4具有功能性 CB 拮抗剂特性,与其与利莫那班的结构关系一致。分子建模分析揭示了氰基与 CB1 结合口袋的结合的重要作用。
