Herein we report the discovery and SAR of a novel antagonist of metabotropic glutamate receptor 4 (mGlu(4)). The antagonist was discovered via a molecular switch from a closely related mGlu(4) positive allosteric modulator (PAM). This antagonist (VU0448383) displays an IC50 value of 8.2 +/- 0.4 mu M and inhibits an EC80 glutamate response by 63.1 +/- 6.6%. (C) 2011 Elsevier Ltd. All rights reserved.
