Potent allosteric potentiator at the rat mGlu5 receptor (EC50 = 9 nM); binds to the MPEP (Cat. No. 1212) allosteric site (Ki app = 244 nM). Selective for mGlu5 over mGlu1 and mGlu2 receptors (EC50 values are 557 nM and 1.51 μM for mGlu1 and mGlu2 respectively). Potentiates both DHPG-induced LTP and threshold θ-burst stimulation (TBS)-induced LTP in rat hippocampal slices. Analog of CDPPB (Cat. No. 3235). Purity 99%. MW (observed): 384.39
