Abstract

Herein, we detail the optimization of the mGlu2 negative allosteric modulator (NAM), VU6001192, by a reductionist approach to afford a novel, simplified mGlu2 NAM scaffold. This new chemotype not only affords potent and selective mGlu2 inhibition, as exemplified by VU6001966 (mGlu2 IC50 = 78 nM, mGlu3 IC50 > 30 μM), but also excellent central nervous system (CNS) penetration (Kp = 1.9, Kp,uu = 0.78), a feature devoid in all previously disclosed mGlu2 NAMs (Kps ≈ 0.3, Kp,uus ≈ 0.1). Moreover, this series, based on overall properties, represents an exciting lead series for potential mGlu2 PET tracer development.
