一般說明

研究领域:神经科学

應用

N-乙酰基-Asp-Glu已用于 N-乙酰化α-连接的酸性二肽酶(NAALADase)测定和亲和力实验。。它也被用作液相色谱-质谱(LC-MS)靶向代谢组学分析 和基于质谱分析的稳定同位素解析 代谢组学 (SIRM)与 13C515N2标记谷氨酰胺的代谢物标准。

生化/生理作用

N-乙酰-Asp-Glu(NAAG)是于哺乳动物大脑中发现的一种丰富的神经肽和神经递质。 NAAG用作代谢性谷氨酸受体mGluR3的激动剂。此外,它还作为N-甲基 -天冬氨酸(NMDA)受体的拮抗剂。它通过谷氨酸羧肽酶II(GCP II)依赖通路生成N-乙酰天门冬氨酸和谷氨酸。因此,它是癌细胞中的关键谷氨酸库。血浆NAAG水平可作为肿瘤进展的非侵入性生物标志物。
内源性神经递质定位于对代谢型谷氨酸受体 mGluR3 具有高亲和力的神经元中。它是 NMDA 受体的拮抗剂。它被星形胶质细胞膜上表达的羧肽酶 II 分解为 N-乙酰天门冬氨酸和谷氨酸。

To develop a robust method for brain metabolite quantification in proton magnetic resonance spectroscopy (1 H-MRS) using a convolutional neural network (CNN) that maps in vivo brain spectra that are typically degraded by low SNR, line broadening, and spectral baseline

This article introduces regularized lineshape deconvolution in conjunction with TE-averaged PRESS spectroscopy to measure N-acetyl-aspartyl-glutamate (NAAG). Averaging different echo times suppressed the signals of multiplets from strongly coupled spin systems near 2 ppm; thus, minimizing the interfering signals to detect

Current medicinal chemistry, 19(9), 1360-1364 (2012-02-07)
At central synapses, glutamate is the main excitatory neurotransmitter. Once released from presynaptic terminals, glutamate activates a number of different glutamatergic receptors one of which is the ligand gated ionophore glutamatergic subtype N-methyl-D-aspartate receptors (NMDARs). NMDARs play a crucial role

Ethanol modulates glutamate and γ-aminobutyric (GABA) function. However, little is known about the acute pharmacologic effects of ethanol on levels of GABA, glutamate, and other metabolites measurable in the human cortex in vivo with proton magnetic resonance spectroscopy ((1)H-MRS). Eleven
