Biological Activity

[Description]:

Quisqualic acid (L-Quisqualic acid), a natural analog of glutamate, is a potent and pan two subsets (iGluR and mGluR) of excitatory amino acid (EAA) agonist with an EC50 of 45 nM and a Ki of 10 nM for mGluR1R. Quisqualic acid is isolated from the fruits of Quisqualis chinensis[1][2].

[Target]

mGluR1R:45 nM (EC50)

mGluR1R:10 nM (Ki)

mGluR2R:108 μM (IC50)

mGluR2R:113 μM (Ki)

mGluR4R:593 μM (IC50)

mGluR4R:112 μM (Ki)

[In Vitro]

Quisqualic acid is an agonist of AMPA and metabotropic glutamate receptors. Quisqualic acid activates mGluR2R (EC50=108 μM; Ki=113 μM) and mGluR4R (EC50=593 μM; Ki=112 μM)[1].
