This article describes recent medicinal chemistry progress toward selective potentiators of the metabotropic glutamate receptor 2 (mGluR2). Groups at Lilly and Merck have identified new classes of potentiators that exhibit selectivity for mGluR2 over the seven other subtypes of mGluRs. Structure-activity relationships as well as pharmacokinetic properties and in vivo activity are reviewed.
