生物活性

(RS)-(Tetrazol-5-yl)glycine (D,L-(tetrazol-5-yl)glycine) is a highly potent and selective N-methyl-D-aspartate (NMDA) receptor agonist[1]. (RS)-(Tetrazol-5-yl)glycine has EC50s of 99 nM, 1.7 μM for GluN1/GluN2D and GluN1/GluN2A, respectively[2]. (RS)-(Tetrazol-5-yl)glycine induces seizure responses and Fos in mice[3].

IC50 & Target

NMDA Receptor

 

体外研究
(In Vitro)

(RS)-(Tetrazol-5-yl)glycine (D,L-(tetrazol-5-yl)glycine) is a agonist of N-methyl-D-aspartate (NMDA) subtype of excitatory amino acid receptor. (RS)-(Tetrazol-5-yl)glycine displaces NMDA receptor binding to rat brain membranes as measured using [3H]CGS19755 (IC50=98 nM) and [3H]glutamate (IC50=36 nM) as ligands[1].
(RS)-(Tetrazol-5-yl)glycine does not appreciably inhibit the binding of D,L-alpha-[5-methyl-3H] amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA), [3H]kainate, or [3H]glycine (IC50s>30 μM)[1].

体内研究
(In Vivo)

(RS)-(Tetrazol-5-yl)glycine 可用于动物建模,构建癫痫模型且可以穿透血脑屏障[4]

1. 诱导癫痫[4]
致病原理
(RS)-(Tetrazol-5-yl)glycine 可以激动 NMDA 受体,引起海马神经毒性损伤,导致癫痫。
具体造模方法:
大鼠:Sprague-Dawley • 雄性或雌性 • 2-6 月龄
给药方式:0.2 和 0.4 μL 的 0.7 mM (RS)-(Tetrazol-5-yl)glycine 溶液 • 脑室注射
Note
(1) 将 (RS)-(Tetrazol-5-yl)glycine 注入大鼠右侧脑室,10 分钟后拔出针头,缝合伤口和头皮。
(2) 在 11 只注射了 0.28 nmol (RS)-(Tetrazol-5-yl)glycine 的大鼠中,有 5 只在注射后数小时内死亡,无法对其进行灌注并确定海马病变程度。
(3) 在 4 只注射了 0.14 nmol (RS)-(Tetrazol-5-yl)glycine 的大鼠中,有 2 只没有海马神经元丢失,而另外 2 只 CA1 内侧部分的锥体神经元和齿状回中的颗粒神经元丢失。
造模成功指标
表型观测: 所有注射了 0.28 nmol (RS)-(Tetrazol-5-yl)glycine 的大鼠均表现出锥体神经元和 CA1-4 及齿状回中 GluR1 免疫活性的广泛丧失。
行为观测: 尾巴不断摆动、划动和抽搐。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
