VU0357121 is a novel positive and highly selective allosteric modulator (PAM) of mGlu5R with EC50 of 33 nM.IC50 Value: 33 nM(EC50)Target: mGluR5in vitro: VU0357121 do not bind at the MPEP allosteric site of mGlu5, thus do not possess mGlu5 NAM activity. The A809V/rmGlu5 mutation inhibited the ability of VU0357121 to shift the glutamate concentration response curve, whereas the response to VU0357121 is not altered by the F585I/rmGlu5 mutation. VU0357121 show weaker cooperativity in the Ca2+ mobilization assay in the low-expressing HEK293A-mGlu5 cell line. in vivo:
