system (CNS), the action of sodium dependent excitatory amino acid transporters (EAATs) is responsible for termination of glutamatergic neurotransmission by reuptake of ( S) -glutamate (Glu) from the synaptic cleft. Five EAAT subtypes have been identified, of which EAAT1-4 are present in the CNS, while EAAT5 is localized exclusively in the retina. In this study, we have used an enantioselective chemo-enzymatic
在哺乳动物的中枢神经系统(CNS)中,钠依赖性兴奋性氨基酸转运蛋白(EAAT)的作用是通过从突触间隙再摄取(S)-谷氨酸(Glu)来终止谷氨酸能神经传递。已经鉴定出五种EAAT亚型,其中EAAT1-4存在于中枢神经系统中,而EAAT5仅位于视网膜中。在这项研究中,我们使用对映选择性化学酶策略合成了10个在4 R位置具有不同功能的新Glu类似物2a-k(2d被豁免),并表征了它们在人EAAT1-3上的药理特性。特别是,一种化合物2k作为EAAT2亚型的抑制剂比EAAT1,3表现出显着的优先性。该化合物对离子型和代谢型Glu受体的亲和力也很低,
