  烷基和烷氧基取代的1,4-二氢喹喔啉-2,3-二酮的结构活性关系：NMDA受体甘氨酸位点的有效和全身活性拮抗剂。

  摘要：

  我们报告了一系列烷基和烷氧基取代的1,4-二氢喹喔啉-2,3-二酮（QXs），作为我们对QXs作为甘氨酸位点拮抗剂的结构-活性关系（SAR）研究的延续而编写N-甲基-D-天冬氨酸（NMDA）受体。这些拮抗剂的体外药效是通过在大鼠大脑皮膜中置换甘氨酸位点放射性配体[3H] -5,7-二氯基尿酸（[3H] DCKA）来确定的。通常，甲基可以很好地取代6位的氯或溴，烷氧基取代的QX的效能比烷基或卤素取代的QX低。乙基取代的QX通常不如甲基取代的QX强，特别是在5,6,7-三取代的QX的6位上。环系统在6,7位融合的结果导致QX的效能低下。几种甲基取代的QXs是有效的甘氨酸位点拮抗剂，在小鼠的最大电击（MES）测试中具有令人惊讶的高体内活性。其中，7-氯-6-甲基-5-硝基QX（14g）（IC50 = 5 nM）和7-溴-6-甲基-5-硝基QX（14f）（IC50 = 9 nM）至6,7-二氯-5-硝基QX（2）（ACEA

  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.
