Selective mGlu2 receptor positive allosteric modulator (EC50 values are 199 and 206 nM for human and rat receptors, respectively). Exhibits negligible activity against a range of neurotransmitter targets, except 5-HT2B and MAO-B (72 and 92% inhibition at 10 μM, respectively). Potentiates inhibitory effect of DCG IV on excitatory postsynaptic potentials in hippocampal slices and ketamine- and methamphetamine-induced increases in locomotor activity in rats and mice.
