The excitatory amino acid transporters (EAATs) are expressed throughout the central nervous system, where they are responsible for the reuptake of the excitatory neurotransmitter (S)-glutamate (Glu).(1) Recently, we have reported the discovery of the first subtype selective EAAT1 inhibitor 2-amino-4-(4-methoxyphenyl)-7-(naphthalen-1-yl)-5-oxo-5,6,7,8-tetrahydro-4H-chromene-3-carbonitrile (UCPH-101)
兴奋性氨基酸转运蛋白(EAAT)在整个中枢神经系统中表达,它们负责兴奋性神经递质(S)-谷氨酸(Glu)的再摄取。(1)最近,我们报道了第一个亚型的发现。选择性EAAT1抑制剂2-氨基-4-(4-甲氧基苯基)-7-(萘-1-基)-5-氧代-5,6,7,8-四氢-4 H-亚甲基-3-腈(UCPH- 101)(1b)并进行了结构-活性关系(SAR)的入门研究。(2)在这里,我们通过类似物1g - 1t的设计,合成和药理学评估给出了详细的SAR 。通过比较1b,1h和1i的效能与1j相比,很明显,效力很大程度上受R 1取代基的化学性质影响。该研究还表明,官能团的任何化学变化或亲本支架的变化都会导致化合物在EAAT1处的抑制活性完全丧失。最终,UCPH-101的生物利用度研究确定其在血清(大鼠)中的半衰期为30分钟,但它也无法显着穿透血脑屏障。
