  描述：

  10-hydroxyimino-imidazo[1,2-a]indeno[1,2-e]pyrazin-2-carboxylic acid 在 ammonium acetate 、 氨 、 锌 作用下， 以 乙醇 为溶剂， 反应 5.0h， 生成 16-Amino-7-oxo-2,5,8-triazatetracyclo[7.7.0.02,6.010,15]hexadeca-1(9),3,5,10,12,14-hexaene-4-carboxylic acid

  Synthesis of anticonvulsive AMPA antagonists

  摘要：

  The overstimulation of excitatory amino acid receptors such as the glutamate AMPA receptor has been implicated in the physiopathogenesis of egilepsy as well as ill acute and chronic neurodegenerative disorders. An original series of readily water soluble 4-oxo-10-substituted-imidazo[1,2-a]indeno[1,2-e]pyrazin-2-carboxylic acid derivatives was synthesized. The most potent derivative 6a exhibited nanomolar binding affinity (IC50=35nM) and antagonist activity (IC50-6nM) at ionotropic AMPA receptor. This compound also demonstrated potent anticonvulsant properties in MES in mice and rats with long durations of action with ED50 values in the 1-3 mg/kg dose range following ip and iv administration.
