Discovery and SAR of novel mGluR5 non-competitive antagonists not based on an MPEP chemotype

Bioorg Med Chem Lett. 2009 Jun 15;19(12):3209-13. doi: 10.1016/j.bmcl.2009.04.110. Epub 2009 May 3.

Abstract

This Letter describes the discovery and SAR of three novel series of mGluR5 non-competitive antagonists/negative allosteric modulators (NAMs) not based on manipulation of an MPEP/MTEP chemotype. This work demonstrates fundamentally new mGluR5 NAM chemotypes with submicromolar potencies, and the first example of a mode of pharmacology 'switch' to provide PAMs with a non-MPEP scaffold.
