Description: ADX-47273 is a potent and selective mGluR5 receptor PAM (positive allosteric modulator), EC50 = 0.17 μm, with no effect on other mGluR subtypes. In vivo, ADX47273 increased extracellular signal-regulated kinase and cAMP-responsive element-binding protein phosphorylation in hippocampus and prefrontal cortex, both of which are critical for glutamate-mediated signal transduction mechanisms. The mGluR (metabotropic glutamate receptor) is a group of G-protein coupled receptors and is active through an indirect metabotropic process. It plays a critical role in regulating synaptic plasticity and neural network activity.
