serves as an indispensable tool for the investigation of the physiological roles of the transporters. To examine the precise interaction between a blocker and the transporters, we synthesized the optically pure isomers (L- and D-TBOA) and its erythro-isomers. L-TBOA is the most potent blocker for the human excitatory amino acid transporters (EAAT1-3), while D-TBOA revealed a difference in the pharmacophores
DL-苏-β-苄氧基天冬氨酸(DL-TBOA)是谷氨酸转运蛋白的不可转运的阻滞剂,它是研究转运蛋白的生理作用必不可少的工具。为了检查阻滞剂和转运蛋白之间的精确相互作用,我们合成了光学纯的异构体(L-和D-TBOA)及其赤型异构体。L-TBOA是人类兴奋性氨基酸转运蛋白(EAAT1-3)的最有效阻滞剂,而D-TBOA显示出EAAT1和EAAT3之间的药效基团有所不同。我们还合成了L-TBOA的取代基变体(甲基或萘基甲基衍生物)。此处获得的结果表明,庞大的取代基对于不可运输的阻滞剂至关重要。
