  Synthesis, Dopamine Transporter Affinity, Dopamine Uptake Inhibition, and Locomotor Stimulant Activity of 2-Substituted 3β-Phenyltropane Derivatives

  摘要：

  A series of 2 beta-substituted 3 beta-phenyltropanes were synthesized as analogs of cocaine and tested in vitro for their ability to displace bound [H-3]WIN 35,428 (2b) and inhibit; dopamine uptake in rat caudate-putamen tissue. The analogs bound with high affinity (K-i = 11-22 nM) to the dopamine transporter. Increased lipophilicity at the beta-C(2)-position was found to lead to increased binding affinity and increased dopamine uptake potency. However, a direct correlation between clogP values and binding affinity and potency of uptake inhibition was not observed. The unsaturated ester 7 was found to possess weak dopamine uptake inhibition relative to the high binding affinity (IC50/K-i = 10.2). In vivo measurement of stimulated locomotor activity and drug discrimination against cocaine (10 mg/kg, ip) with selected analogs (4, 6, and 7) demonstrated that the behavioral effects of these drugs were approximately equipotent with those of cocaine, The structure-activity relationships of this series of cocaine analogs supports a pharmacophore model in which lipophilic interactions between the B-C(2)position of 3 beta-phenyltropanes and the cocaine binding site on the dopamine transporter lead to enhanced potency while electrostatic interactions have a nonspecific effect.

  摘要：

  在努力确定可能充当可卡因拮抗剂或可卡因部分激动剂的分子的过程中，我们参与了通过结构上的战略性修饰来进一步阐明可卡因与多巴胺转运蛋白（DAT）结合的性质的努力。在取代基位于托环环的2位的情况下，研究表明转运蛋白能够容纳多种结构的基团，包括酯，酮，烷基，烯基，杂环和芳基取代基，而不会损失DAT绑定亲和力。在本研究中，我们报告了有关DAT容纳WIN型结构的能力的结果，该结构在2位具有烷基或芳基，并且采用了环烷的椅子或船形。而且，我们讨论了这些化合物的立体化学对DAT相对于血清素转运蛋白（5HTT）的选择性的影响。此外，我们指出了在进行转运蛋白选择性的比较时，使用Ki值而不是IC50值的重要性。在本研究中鉴定出的最有趣的化合物之一是船形的2，3-二芳基托烷22，它对DAT的选择性比5HTT高（69倍）。通过我们基于氧化吡啶鎓甜菜碱的偶极环加成策略制备该化合物及相关结构的能力进一步强调了这种特殊化学
