M. Rowley et al., 5,6,7,8-TETRAHYDROQUINOLONES AS ANTAGONISTS AT THE GLYCINE SITE OF THE NMDA RECEPTOR, Bioorganic & medicinal chemistry letters, 5(18), 1995, pp. 2089-2092
The effect of reducing the benzo ring of a series of 4-hydroxyquinolon
e Glycine/NMDA antagonists is described. It is important that the ring
be present, but not that it is aromatic. Provided that the correct li
pophilic interactions are present, high affinity is found in 4-hydroxy
-5,6,7,8 -tetrahydroquinolones.
