inhibitors, exhibiting pan activity at EAAT1–4 with IC50 values ranging from 0.49 to 15 μM. Comparisons between (dl-threo)-19a–c and (dl-erythro)-19a–c Asp analogues confirmed that the threo configuration is crucial for the EAAT1–4 inhibitory activities. Analogues (3b–e) of l-TFB-TBOA (3a) were shown to be potent EAAT1–4 inhibitors, with IC50 values ranging from 5 to 530 nM. Hybridization of the nonselective
天冬氨酸(Asp)衍生物是特权化合物,可用于研究谷氨酸能神经传递中兴奋性氨基酸转运蛋白(EAAT)的作用。在这里,我们报告了在C-3处带有(环)烷氧基和(杂)芳氧基取代基的各种Asp衍生物的合成。在EAAT1-4亚型中对它们的药理特性进行了表征。的升-苏-3-取代的天冬氨酸衍生物13A - ë和13克- ķ是nonsubstrate抑制剂,在表现出EAAT1-4锅活性与IC 50值范围为0.49至15μm。(dl - threo)-19a – c之间的比较和(DL -赤) - 19A - Ç天冬氨酸类似物证实,苏式配置是EAAT1-4抑制活性是至关重要的。1 -TFB-TBOA(3a)的类似物(3b - e)被证明是有效的EAAT1-4抑制剂,IC 50值为5至530 nM。非选择性EAAT抑制剂1 -TBOA与EAAT2选择性抑制剂WAY-213613或EAAT3优选抑制剂NBI-591
