mGluR4 Activator

ADX88178 TFA is an orally active, blood-brain barrier-penetrant, selective positive allosteric modulator of mGluR4, with an EC₅₀ of 3.5 nM against hmGluR4. ADX88178 TFA modulates mGlu4 activity, enhances glutamate-mediated receptor activation, and increases the apparent affinity of glutamate for the receptor. ADX88178 TFA reverses haloperidol-induced catalepsy, potentiates the effects of levodopa (L-DOPA) and quinpirole, but fails to alleviate established abnormal involuntary movements, does not exacerbate L-DOPA-induced dyskinesia, and does not affect forelimb akinesia when administered alone. ADX88178 TFA can be used in research related to L-DOPA-induced dyskinesia and Parkinson's disease.

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 K_i of 10 nM for mGluR1R. Quisqualic acid is isolated from the fruits of Quisqualis indica.
