    Product Description

    ADX-88178 is a positive allosteric modulator (PAM) of metabotropic glutamate receptor 4 (mGluR4).1 It enhances glutamate-induced intracellular calcium mobilization in HEK293 cells expressing human or rat mGluR4 (EC50s = 3.5 and 9.1 nM, respectively). ADX-88178 is selective for mGluR4 over mGluR1, mGluR2, mGluR3, mGluR5, mGluR7, and the GABAB receptor at 30 µM, mGluR6 at 10 µM, and mGluR8 (EC50 = 2.2 µM). It is also selective for mGluR4 over a panel of 71 receptors, transporters, enzymes, and ion channels at 10 µM. ADX-88178 (10 mg/kg) reverses catalepsy induced by haloperidol (Item No. 12014) in rats. It enhances L-DOPA-induced decreases in motor impairments in 6-OHDA-lesioned rats in a dose-dependent manner. However, it does not reverse L-DOPA- and benserazide-induced dyskinesia in 6-OHDA-lesioned rats.2
