Description

A-841720, a novel, potent and non-competitive mGluR1 antagonist in models of pain and of motor and cognitive function, is being under development by Merz Pharmaceuticals GmbH. It is a selective non-competitive mGlu1 receptor antagonist (IC50: 10 nM); showing 34-fold selectivity over mGluR5 and no significant activity at other mGluR receptors, neurotransmitter receptors, ion channels, and transporters. A-841720 demonstrated full efficacy in various in vivo animal pain models.
