MTEP hydrochloride


Product overview

  • Name
    MTEP hydrochloride
  • Short description
    Potent, highly selective, non-competitive mGluR5 antagonist
  • Biological description

    MTEP hydrochloride is a potent, highly selective and non-competitive mGlu5 receptor antagonist (IC50 = 5 nM and Ki = 16 nM in an in vitro Ca2+-flux assay).

    MTEP has no significant effect on other mGluRs and shows fewer off-target effects than MPEP hydrochlorideMTEP shows ~10-fold greater selectivity for mGlu5 than MPEP.

    MTEP also blocks induction of tLTP (timing-dependent long term potentiation) and has antidepressant, anxiolytic and neuroprotective properties.

    MTEP is active in vivo.
