  Synthesis and transporter binding properties of (R)-2β,3β- and (R)-2α,3α-diaryltropanes

  摘要：

  (R)-2-Aryl-2-tropinone (9) was synthesized from (R)-2-carbomethoxy-3-tropinone (5) and was used as the key intermediate for the synthesis of (R)-2 beta,3 beta- and (R)-2 alpha,3 alpha-diaryltropanes. Inhibition of radioligand binding studies at the dopamine, serotonin, and norepinephrine transporters showed that the (R)-3 beta-(4-methylphenyl)-2 beta-phenyltropane (3b, RTI-422) possessed an IC50 value of 1.96 nM at the dopamine transporter and was highly selective for this transporter relative to the serotonin and norepinephrine transporters.

  present work is a 2, 3-diaryltropane 22 in a boat conformation that is highly selective (69-fold) for the DAT over the 5HTT. The ability to prepare this compound as well as related structures by our oxidopyridinium betaine-based dipolar cycloaddition strategy further underscores the versatility of this particular chemical approach to the preparation of diverse tropane analogues. The use of the optically

  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

  Synthetic procedures were developed for the synthesis of 2 beta,3 beta- and 2 alpha,3 alpha-diaryltropanes. These compounds are analogues of the 3-aryltropane-2 beta-carboxylic acid methyl ester class of monoamine uptake inhibitors, where the 2 beta-carbomethoxy group has been replaced by an aryl group. The compounds were evaluated for inhibition of radioligand binding at the dopamine, norepinephrine, and serotonin transporters (DAT, NET, and 5-HTT, respectively). The results showed that the replacement of the 2 beta-carbomethoxy group in the 3-aryltropane class with a 2 beta-aryl group led to compounds possessing very similar monoamine transporter binding properties. However, the 2 beta,3 beta-diaryltropanes tended to be more potent at the DAT and more selective for the DAT relative to the NET and 5-HTT. One of the most interesting compounds was 3 beta-(4-methylphenyl)-2 beta-(4-methylphenyl)tropane (3d), which showed an IC50 of 1.23 nM at the DAT with 289- and 185-fold selectivity for the DAT relative to the NET and 5-HTT. The 2 alpha,3 alpha-diaryltropanes were much less potent at all three transporters than 2 beta,3 beta-diaryltropanes.
