has always been used in its racemic form. To establish whether or not its beneficial therapeutic actions are enantiospecific, a practical total synthetic route was developed to yield each enantiomeric form to allow their chemical and pharmacological characterization. We briefly summarize the total synthesis of TBZ and report a detailed procedure for resolution of TBZ into its enantiomers, (+)-TBZ and
作为治疗多动性运动障碍的临床药物,在亨廷顿病等疾病中,丁苯那嗪 (TBZ) 一直以其外消旋形式使用。为了确定其有益的治疗作用是否具有对映特异性,开发了一种实用的全合成路线来产生每种对映体形式,以对其进行化学和药理学表征。我们简要总结了 TBZ 的全合成,并报告了将 TBZ 拆分为其对映体 (+)-TBZ 和 (-)-TBZ 的详细程序。这允许基于 X 射线晶体学分析确定每个 TBZ 对映异构体的旋光度和绝对构型,同时表征它们对囊泡单胺转运蛋白 2 的抑制作用,其中 (+)-TBZ 证明比活性高 3 倍(-)-TBZ。
