beta-phenyl-2-substituted-9-azabicyclo[3.3.1]nonane derivatives were synthesized and evaluated as cocaine-binding site ligands at the dopamine transporter (DAT). The conformation of the bicyclic structures and the stereochemistry of the substituents were determined by NMR and X-ray crystallography. The in vitro binding affinity (Ki) of the 9-azabicyclo[3.3.1]nonane derivatives was measured in rat caudate-putamen
合成了一系列9-甲基-3β-苯基-2-取代的9-氮杂双环[3.3.1]壬烷衍生物,并在多巴胺转运蛋白(DAT)上作为可卡因结合位点配体进行了评估。通过NMR和X射线晶体学测定双环结构的构象和取代基的立体化学。在大鼠尾状丘脑组织中测量了9-氮杂双环[3.3.1]壬烷衍生物的体外结合亲和力(Ki),发现其效力比可卡因低100倍(Ki = 2-14 microM)和其他托烷类似物。从这些结果可以看出,DAT上的可卡因结合位点对可卡因和可卡因样化合物的未取代亚甲基桥[C(6)-C(7)]的结构修饰非常敏感。
