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].
In Vivo (RS)-(Tetrazol-5-yl)glycine (D,L-(tetrazol-5-yl)glycine; 1.25, 1.5 mg/kg; IP) induces seizure responses and Fos in the NR1+/+ and NR1-/- mice[3]. (RS)-(Tetrazol-5-yl)glycine is a highly potent convulsant when given to neonatal rats (ED50=0.071 mg/kg; i.p.) [1]. Animal Model: C57BL/6 mice[3] Dosage: 1.25, 1.5 mg/kg Administration: IP Result: Induced seizure responses and Fos.
