Bioorg Med Chem Lett. 2013 Mar 1;23(5):1472-6. doi: 10.1016/j.bmcl.2012.12.056. Epub 2012 Dec 22.

Abstract

We described here the synthesis and biological evaluation of mGluR5 antagonists containing a quinoline ring structure. Using intracellular calcium mobilization assay (FDSS assay), we identified compound 5n, showing high inhibitory activity against mGluR5. In addition, it was found that compound 5n has excellent stability profile. Finally, this compound exhibited favorable analgesic effects in spinal nerve ligation model of neuropathic pain, which is comparable to gabapentin.
