Phenyl ureas of creatinine as mGluR5 antagonists. A structure-activity relationship study of fenobam analogues

Bioorg Med Chem Lett. 2006 Mar 1;16(5):1142-5. doi: 10.1016/j.bmcl.2005.11.092. Epub 2005 Dec 27.

Abstract

Fenobam (1) was developed by McNeil Laboratories as an anxiolytic agent with an unknown molecular target in the late 1970s. In a recent publication, it was revealed that fenobam is a non-competitive mGluR5 antagonist. Herein, we present the structure-activity relationship of fenobam and its analogues and similarities between the SAR of mGluR5 antagonism and the SAR of CNS properties originally reported by McNeil are discussed.
