Abstract: This letter describes the further optimization of a series of mGlu3 NAMs based on an N-aryl phenoxyethoxy pyridinone core. A multidimensional optimization campaign, with focused matrix libraries, quickly established challenging SAR, enantiospecific activity, differences in assay read-outs (Ca2+ flux via a promiscuous G protein (Gα15) versus native coupling to GIRK channels), identified both full and partial mGlu3 NAMs and a new in vivo tool compound, VU6017587. This mGlu3 NAM showed efficacy in tail suspension, elevated zero maze and marble burying, suggesting selective inhibition of mGlu3 affords anxiolytic-like and antidepressant-like phenotypes in mice.
