Abstract

We have identified and synthesized a series of 4-thiopyridyl acetophenones as positive allosteric potentiators of the metabotropic glutamate receptor 2. Structure-activity relationship studies directed toward replacement of the tetrazole in the initial lead led to the discovery of 16 (EC(50)=340 nM), which showed improved brain penetration over the initial lead.
