enantiomerically pure diasteroisomers of γ-benzyloxy-S-glutamic acid was performed using trans-4-hydroxy-l-proline as a source of chirality, while the erythro and threo isomers of β-benzyloxy-S-glutamic acid were prepared starting from (R)-Garner's aldehyde. All new derivatives were tested for their inhibitory activity against excitatory amino acid transporters in a rat synaptosomal preparation and their
γ苄氧基的两个对映体纯非对映异构的有效立体选择性制备小号使用进行谷氨酸反式-4-羟基-升-脯氨酸作为手性源,而赤和苏β苄氧基的异构体小号-从(R)-加纳醛开始制备谷氨酸。测试了所有新衍生物在大鼠突触体制剂中对兴奋性氨基酸转运蛋白的抑制活性,并将其IC 50值与TBOA(一种通常用作谷氨酸转运蛋白的参考阻滞剂的低碳同系物)的IC 50值进行了比较。
