ADX47273 causes a concentration-dependent increase in the response to 50 nM glutamate in HEK 293 cells expressing rat mGlu5, the maximal increase in the response is approximately 9-fold, with an EC50 of 0.17 ± 0.03 μM. ADX47273 causes a concentration-dependent increase in the response to 300 nM glutamate with an EC50 value of 0.23 ± 0.07 μM in primary astrocyte cultures. ADX47273 at concentration of 0.1 or 1 μM decreases the EC50 for glutamate for 4- and 9-fold, respectively, in HEK 293 cells expressing rat mGlu5. ADX47273 at concentration of 1 or 3 μM decreases the EC50 for glutamate for 4- and 9-fold, respectively, in primary astrocyte cultures. ADX47273 inhibits binding of MPEP to membranes prepared from HEK 293 cells expressing mGlu5 receptors with Ki of 4.3 ± 0.5 μM. ADX-47273 at concentration of 0.3 μM elicited an enhancement of NMDA-receptor dependent long-term potentiation in rat hippocampal slices, the effect can be blocked in the presence of 10 μM specific mGlu5 receptor antagonist MPEP.
