  Structure−Activity Relationships of 1,4-Dihydro-(1H,4H)-quinoxaline-2,3-diones as N-Methyl-d-aspartate (Glycine Site) Receptor Antagonists. 1. Heterocyclic Substituted 5-Alkyl Derivatives

  摘要：

  A series of 6,7-dichloro-1,4-dihydro-(1H, 4H)-quinoxaline-2,3-diones (1-17) were prepared in which the 5-position substituent was a heterocyclylmethyl or 1-(heterocyclyl)-1-propyl group. Structure-activity relationships were evaluated where binding affinity for the glycine site of the N-methyl-D-aspartate (NMDA) receptor was measured using the specific radioligand [H-3]- L-689,560, and functional antagonism was demonstrated by inhibition of NMDA-induced depolarizations of rat cortical wedges. The ability to prevent NMDA-induced hyperlocomotion in mice in vivo was measured for selected compounds. Binding affinity increased significantly if the heterocyclic group, e.g. 1,2,3-triazol-1-yl could participate in accepting a hydrogen bond from the receptor. It was difficult to obtain compounds with adequate aqueous solubility and strategies to improve it were investigated. The most potent compound in this series, 6,7-dichloro-5-[1-( 1,2,4-triazol-4-yl)propyl]-1,4-dihydro-(1H, 4H)-quinoxaline-2,3-dione (17) (binding IC50 = 2.6 nM; cortical wedge EC50 = 90 nM), inhibited NMDA-induced hyperlocomotion in mice (6/9 protected at 20 mg/kg iv). Pharmacokinetic parameters, including extent of brain penetration, for 11 and 17 are reported.
