β-Spaglumic acid
Based on 1 publication(s) in Google Scholar
β-Spaglumic acid (β-NAAG) is a competitive NAAG peptidase inhibitor (Ki=1 µM) that protects spinal cord neurons from excitotoxicity and hypoxic damage. β-Spaglumic acid is also a selective mGluR3 antagonist (mGluR3 receptor functions to regulate activity-dependent synaptic potentiation in the hippocampus). β-Spaglumic acid can be used in neuroprotection-related studies.

Biological Activity
β-Spaglumic acid (63-1000 µM; 2 h) protects against NMDA-induced injury of spinal cord cells in a dose-dependent manner[1].
β-Spaglumic acid (0-1000 µM; 2 h) protects spinal cord cells against hypoxia[1].
β-Spaglumic acid (500 µM) significantly reduces intraneuronal free Ca2+ responses upon neuronal exposure to 25 µM NMDA[1].
β-Spaglumic acid (100 µM; 7 min) antagonizes mGluR3 in cerebellar granule cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:Spinal cord cells (NMDA-induced) (from spinal cords removed from prenatal day 15 Sprague-Dawley rat fetuses)
-
Concentration:63-1000 µM
-
Incubation Time:2 h
-
Result:Led to a significant attenuation of NMDA toxicity at a concentration of 63 µM and completely blocked NMDA toxicity with 500 and 1000 µM concentrations.
Apparently minimized the basal loss of cell viability associated with experimental handling of the cells (e.g. serum removal, media changes).
-
Cell Line:Spinal cord cells (hypoxic-induced)
-
Concentration:0-1000 µM
-
Incubation Time:2 h
-
Result:Provided 75% protection during hypoxia when at 8 µM and completely eliminated hypoxia-induced loss of viability (107.4-114.4% protection, respectively) when at 63-1000 µM.
-
Cell Line:Cerebellar granule cells (expressing group I-III mGluRs)
-
Concentration:100 µM
-
Incubation Time:7 min
-
Result:Blocked NAAG inhibition of forskolin-stimulated cAMP formation via mGluR3.
