Discovery, synthesis, and structure–activity relationships of 2-aminoquinazoline derivatives as a novel class of metabotropic glutamate receptor 5 negative allosteric modulators
摘要:
A virtual screening approach using various in silico methodologies led to the discovery of 2-(m-tolylamino)-7,8-dihydroquinazolin-5(6H)-one (1) as a moderately active negative allosteric modulator (NAM) of the metabotropic glutamate receptor subtype 5 (mGluR5) showing high selectivity against the subtype mGluR1. Modifications of the parent compound by rational design yielded a series of highly potent derivatives which will serve as valuable starting points for further hit-to-lead optimization efforts toward a suitable drug candidate for the treatment of L-DOPA induced dyskinesia.

functional activity at the α2-adrenoceptor, a G-protein-coupled receptor with relevance in several neuropsychiatric conditions. In this paper we describe the design, synthesis, and pharmacological evaluation of a new series of pyridine derivatives [para substituted 2- and 3-guanidino and 2- and 3-(2-aminoimidazolino)pyridines, disubstituted 2-guanidinopyridines and N-substituted-2-amino-1,4-dihydroquinazolines]
