AZ 12216052 is a positive allosteric modulator of metabotropic glutamate receptor 8 (mGluR8). It potentiates glutamate-induced [S]GTPγS binding in GHEK cells expressing human mGluR8b (EC = 1 μM). In a cell-based model of Parkinson’s disease, AZ 12216052 inhibits MPP-induced decreases in the viability of undifferentiated SH-SY5Y cells when used at concentrations ranging from 0.001 to 1 μM and in retinoic acid-differentiated SH-SY5Y cells at 0.1 and 1 μM. AZ 12216052 (10 mg/kg) increases the time spent in the open areas of the elevated zero maze and reduces the acoustic startle response in mice, indicating anxiolytic-like activity in response to avoidable and unavoidable anxiogenic stimuli, respectively.
AZ 12216052 is a mGluR8 positive allosteric modulator, and helps mGluR8 modulate signaling inputing to retinal ganglion cells. AZ 12216052 exhibits antianxiety effect.

Dosage:
10 mg/kg
Administration:
Intraperitoneal injection; singel dose, 2 h prior to testing
Result:
Reduced measures of anxiety in the elevated zero maze without affecting the velocity of the mice.
