oocytes expressing rat brain NMDA and AMPA receptors. THHBADs are antagonists of NMDA and AMPA receptors with functional potency being dependent upon the substitution pattern on the tetrahydrobenzene moiety. The 7,8-dichloro-6-methyl (18a) and 7,8-dichloro-6-ethyl (18b) analogs are the most potent THHBADs prepared and have apparent antagonist dissociation constants (Kb values) of 0.0041 and 0.0028 microM
描述了几种外消旋的6,7,8,9-四氢-3-羟基-1H-1-苯并ze庚因-2,5-二酮(THHBADs)的合成和药理特性。通过与5,6,7,8-四氢-2-甲氧基萘-1,4-二酮(THMND)的施密特反应完成合成,然后进行去甲基化。通过与2-甲氧基苯醌(5)或2-溴-5-甲氧基苯醌(14)和取代的1,3-丁二烯的Diels-Alder反应制备THMND。THHBADs的药理学特征是在非洲爪蟾卵母细胞中表达大鼠脑NMDA和AMPA受体的电记录。THHBAD是NMDA和AMPA受体的拮抗剂,其功能效力取决于四氢苯部分上的取代方式。7,8-二氯-6-甲基(18a)和7
