Abstract
We have identified and synthesized a brain penetrant propanoic acid as an allosteric potentiator of the metabotropic glutamate receptor 2. Structure-activity relationship studies directed toward improving the potency, level of potentiation and brain penetration led to the discovery of 8 (EC50=1200 nM, 77% potentiation, 119% brain/plasma in rat, 20 mpk i.p., brain level of 5700 nM).
