BioAssay: AID 594387

Positive allosteric modulator activity at mGluR5 receptor expressed in HEK293A cells assessed as effect on glutamate-induced calcium flux preincubated for 140 secs before glutamate challenge by calcium fluorescence assay

This Letter describes a chemical lead optimization campaign directed at a weak mGlu(5) NAM discovered while developing SAR for the mGlu(5) PAM, ADX-47273. An iterative parallel synthesis effort discovered multiple, subtle molecular switches that afford potent mGlu(5) NAMs, mGlu(5) PAMs as well as mGlu(5) partial antagonists. ..more

Description:
Title: Discovery of molecular switches within the ADX-47273 mGlu5 PAM scaffold that modulate modes of pharmacology to afford potent mGlu5 NAMs, PAMs and partial antagonists.

Abstract: This Letter describes a chemical lead optimization campaign directed at a weak mGlu(5) NAM discovered while developing SAR for the mGlu(5) PAM, ADX-47273. An iterative parallel synthesis effort discovered multiple, subtle molecular switches that afford potent mGlu(5) NAMs, mGlu(5) PAMs as well as mGlu(5) partial antagonists.
