Biological Data

Biological description

MPEP hydrochloride is a potent, selective and non-competitive mGlu5 receptor antagonist (IC50 = 36 nM) and also a mGlu4 receptor positive allosteric modulator (PAM).

MPEP prevents induction of various types of long term potentiation (LTP) and long term depression (LTD).

MPEP also suppresses addiction-like behaviour for cocaine, ethanol and nicotine in various models of addiction. MPEP is blood-brain barrier (BBB) permeable and is active in vivo.

Water soluble MTEP hydrochloride is also available.
