The excitatory amino acid transporters (EAATs) play essential roles in regulating the synaptic concentration of the neurotransmitter glutamate in the mammalian central nervous system. To date, five subtypes have been identified, named EAAT1–5 in humans, and GLAST, GLT-1, EAAC1, EAAT4, and EAAT5 in rodents, respectively. In this paper, we present the design, synthesis, and pharmacological evaluation
兴奋性氨基酸转运蛋白(EAAT)在调节哺乳动物中枢神经系统中神经递质谷氨酸的突触浓度中起重要作用。迄今为止,已鉴定出五种亚型,在人类中分别命名为EAAT1-5,在啮齿动物中分别命名为GLAST,GLT-1,EAAC1,EAAT4和EAAT5。在本文中,我们介绍了UCPH-101 / 102的7个7- N-取代的类似物的设计,合成和药理学评估。类似物9在微摩尔范围内抑制了EAAT1(IC 50值为20μM),而类似物8和10没有活性(IC 50值> 100μM)。非对映体对11a / 11b和通过HPLC分离12a / 12b,通过VCD技术将绝对构型与从头算起的Hartree-Fock计算相结合。类似物11A(RS -异构体)和12B(RR异构体)抑制EAAT1(IC 50个值5.5和3.8μM,分别地),而类似物11B(SS -异构体)和12A(SR -异构体)不能抑制EAAT1摄取(IC
