  3-Hydroxy-quinolin-2-ones: Inhibitors of [3H]-glycine binding to the site associated with the NMDA receptor

  摘要：

  A series of substituted 3-hydroxy-quinolin-2-one derivatives 6 was synthesized and evaluated as inhibitors of [H-3]-glycine and [H-3]-AMPA binding to rat cortical membranes. These compounds were generally found to be more potent ligands for the NMDA-associated glycine binding site than the AMPA receptor. Affinity for the glycine site was found to be influenced by both the electronic and steric properties associated with the C-4 substituent and the nature and pattern of substitution of the aromatic ring. The most active compound in this series, 6y, displaces [H-3]-glycine with an IC50 of 29 nM.

  Several 3-hydroxyquinolin-2(1H)-ones. derivatives were synthesized and evaluated as inhibitors of 2009 pandemic H1N1 influenza A endonuclease. All five of the monobrominated 3-hydroxyquinolin (1H)-2-ones derivatives were synthesized. Suzuki-coupling of p-fluorophenylboronic acid with each of these brominated derivatives provided the respective p-fluorophenyl hydroxyquinolin (1H)-2-ones. In addition to 3-hydroxyquinolin-2 (1H)-one, its 4-methyl, 4-phenyl, 4-methyl-7-(p-fluorophenyl), and 4-phenyl-7-(p-fluorophenyl) derivatives were also synthesized. Comparative studies on their relative activity revealed that both 6- and 7-(p-fluorophenyl)-3- hydroxyquinolin-2(1H)-one are among the more potent inhibitors of H1N1 influenza A endonuclease. An X-ray crystal structure of 7-(p-fluorophenyl)-3-hydroxyquinolin-2(1H)-one complexed to the influenza endonuclease revealed that this molecule chelates to two metal ions at the active site of the enzyme.
