synaptosomal [3H]D-aspartic acid uptake (IC(50) = 93 +/- 25 microM), as well as excitatory amino acid transporters (EAATs) EAAT1 (IC(50) = 100 +/- 30 microM) and EAAT2 (IC(50) = 300 +/- 80 microM). By contrast, compound 8b showed no appreciable affinity for Glu uptake sites, neither synaptosomal nor cloned. Compounds 9a-c and 10a,b, possessing 1-hydroxyimidazole as the terminal acidic function, were devoid
合成了多种1-羟基唑衍生物,作为(S)-谷氨酸(Glu)的生物等排体和AMPA受体激动剂(R,S)-2-氨基-3-(3-羟基-5-甲基- 4-异恶唑基)丙酸(AMPA,3b)。所有化合物均进行了体外药理研究,包括一系列Glu受体结合测定,天然和克隆Glu摄取系统的摄取研究以及电生理大鼠皮层切片模型。化合物7a,b(带有1-羟基-5-吡唑基部分作为远端羧基官能团的AMPA类似物)仅对[3H] AMPA受体结合位点具有中等亲和力(IC(50)= 2.7 +/- 0.4 microM和IC (50)分别为2.6 +/- 0.6 microM),与大鼠皮质楔形模型的电生理数据相关(EC(50)= 280 +/- 48 microM,EC(50)= 586 +/- 41 microM,分别)。化合物8a,b的AMPA的1-羟基-1,2,3-三唑-5-基类似物对[3H] AMPA受体结合位点表现出高亲和力(IC(50)=
