Metabolism studies with ethyl [5-amino-1,2-dihydro-2-methyl-3-phenylpyrido[3,4-b]pyrazin-7 - yl]carbamate (1) in mice were reported previously to give a hydroxylated metabolite, which was methylated to give a methoxy derivative. The metabolite and its derivatives were considered to be 4-(substituted)phenyl compounds, which have been confirmed by the synthesis of the [1,2-dihydro-3-(4-hydroxyphenyl)-
先前曾有报道称[5-氨基-1,2-二氢-2-甲基-3-苯基吡啶并[3,4-b]吡嗪-7-基]氨基甲酸酯乙酯在小鼠中的代谢研究产生羟基化代谢物,甲基化得到甲氧基衍生物。代谢物及其衍生物被认为是4-(取代)苯基化合物,已通过[1,2-二氢-3-(4-羟苯基)-和[1,2-二氢-3]的合成得到证实。 -(4-甲氧基苯基)吡啶并[3,4-b]-吡嗪-7-基]氨基甲酸酯(17和16)。17的S和R异构体在几种生物系统中均具有活性,但是S异构体比R异构体更有效。17的S和R异构体之间的活性差异与1的S和R异构体所观察到的相似。
