    • The 3&agr; isomer of RTI-55, RTI-352, is an effective in vivo binding ligand that reflects greater selectivity for the dopamine transporter than is observed with RTI-55. In addition, there is also a more rapid achievement of apparent equilibrium in the striatal-to-cerebellar ratio (compared to RTI-55) as the ratio peaks at about 30 min and is maintained for about 20 min thereafter. Such apparent equilibrium is useful in developing an approach to measuring the number of dopamine transporters present in tissues. Moreover, these results indicate that the utilization of 3&agr; isomers of a variety of 3&bgr;-(substituted phenyl)tropanes will result in greater selectivity for dopamine transporters and a more rapid of achievement of apparent equilibrium.
    • RTI-55,RTI-352的3α异构体是一种有效的体内结合配体,其反映了对多巴胺转运蛋白的选择性高于用RTI-55观察到的选择性。 另外,纹状体与小脑的比例(与RTI-55相比)的表观平衡也更快,因为在30分钟左右的比例达到峰值,此后保持约20分钟。 这种表观平衡在开发测量组织中存在的多巴胺转运蛋白数量的方法中是有用的。 此外,这些结果表明,使用各种3'-巯基(取代苯基)托烷的3α异构体将导致对多巴胺转运蛋白的更高选择性和更快速地达到表观平衡。

    • An optically active tropinonemonocarboxylic acid ester derivative useful as an intermediate for synthesis of optically active tropane derivatives was obtained by reacting succindialdehyde with an organic amine and acetonedicarboxylic acid ester to obtain a tropinonedicarboxylic acid ester derivative, and then subjecting this derivative to enzyme-catalyzed asymmetric dealkoxy-carbonylation. Since anhydroecgonine methyl ester derived from the optically active tropinone-monocarboxylic acid ester derivative by reduction and dehydration had the same direction of optical rotation as in the case of anhydroecgonine methyl ester obtained from natural cocaine, it was proved that the obtained optically active tropinonemonocarboxylic acid ester derivative had the same absolute configuration as that of natural cocaine. The yield of the optically active tropinonemonocarboxylic acid ester derivative from the asymmetric dealkoxycarbonylation was 30 to 50 mol %, and its optical purity was 70 to 97% ee. In addition, it was found that a crystalline optically active anhydroecgonine carboxylic acid ester derivative can be obtained by reducing and then dehydrating the optically active tropinonemonocarboxylic acid ester derivative and that its optical purity can easily be increased by recrystallization.
