  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.

  Regiospecific Oxidative Nitration of 3,4-Dihydro-6,7-disubstituted Quinoxaline-2(1H)-ones Gives 1,4-Dihydro-5-nitro-6,7-disubstituted Quinoxaline-2,3-diones, Potent Antagonists at the NMDA/Glycine Site

  摘要：

  The regiospecific oxidative nitration of 3,4-dihydro-6,7-disubstituted quinoxalin-2(1H)-ones (15a-h, 20) utilizing fuming nitric acid in TFA gave 1,4-dihydro-5-nitro-6,7-disubstituted quinoxaline-2,3-diones (6a-i), respectively, in good yields. Compounds 15a-h were prepared from commercially available 1-halo-3,4-disubstituted benzenes 12a-h in three steps. These were nitration, nucleophilic substitution of the halogen ortho to the nitro group with sodium glycinate, and finally, reduction of the nitro group and concomitant cyclization, Compound 20 was prepared from 16 by a different route involving alkylation of substituted o-nitroaniline 18. The final oxidative nitration yields a single, predictable nitro isomer and is a significant improvement over the direct nitration of 6,7-disubstituted quinoxaline-2,3-diones.
