mGluR4 4 nM (EC50)

ADX88178 is developed as a potent and selective mGluR4 positive allosteric modulator. ADX88178 is used as a novel radioligand for imaging of metabotropic glutamate receptor subtype 4 (mGluR4). ADX88178 potentiates glutamate-mediated activation of human mGluR4 with EC50 values of 4 nM without significant effects on other mGluRs (EC50 > 30 μM). ADX88178 is novel potent, selective, and brain-penetrant positive allosteric modulator of the mGlu4. Microglia are pretreated with 1, 10 or 100 nM ADX88178 or 100 nM LAP4 for 30 min followed by LPS treatment for 24 h prior to collecting culture supernatant for ELISA measurement of TNFα levels. The pre-treatment with ADX88178 and LAP4 both significantly attenuate LPS-induced TNFα levels. As little as 1 nM of ADX88178 is sufficient to inhibit TNFα, and is as effective at concentrations of 10 and 100 nM.

In mice, ADX88178 (1-30 mg/kg p.o.) dose-dependently increases the number of open-arm entries. Specifically, at 3, 10, and 30 mg/kg ADX88178, there are 5-, 7-, and almost 13-fold increases in the number of open-arm entries, respectively, when compared with the vehicle-treated controls. Also, ADX88178 dose-dependently increases the time spent in the open arms. Specifically, at 3, 10, and 30 mg/kgADX88178, there are 8-, 12-, and 24-fold increases in the time spent in the open arms when compared with the vehicle-treated controls. In rats, ADX88178 (10-100 mg/kg p.o.) dose-dependently increases the number of open-arm entries in the rat EPM test. Specifically, at 10, 30, and 100 mg/kg ADX88178, there are 5-, 8-, and more than 10-fold increases in the number of open-arm entries, respectively, when compared with the vehicle-treated controls. Also, ADX88178 dose-dependently increases
