    摘要:
    一组新的5,6-二氢-吡唑并[1,5-c]喹唑啉-2-羧酸酯(2-18),在位置-上带有不同的取代基(COOEt,Cl,Br,CH(3)和COOH)为了研究在该特定位置上的各个基团对Gly / NMDA受体亲和力和/或选择性的影响,合成了图1的化合物。评价所有本文报道的化合物在Gly / NMDA,AMPA和KA受体上的结合。还测试了一些选定的化合物在AMPA和NMDA受体离子通道上的功能拮抗活性。在这项研究中获得的结果表明,吡唑并[1,5-c]喹唑啉-2-羧酸酯核上的C-1亲脂取代基使选择性向Gly / NMDA受体转移,而C-1阴离子羧酸酯残基能够以增加对该受体亚型的亲和力。特别是,在位置1处带有氯原子的2-羧酸15和16不仅有效(分别为K(i)= 0.18和0.16μM),而且相对于AMPA选择性具有很高的Gly / NMDA选择性(选择性比> 500) )。此外,在吡唑并喹唑啉系列

    Reactions of 3-diazo-1,3-dihydro-2H-indol-2-one derivatives with enaminones. A novel synthesis of 1,2,3-triazoles
    摘要:
    A new and efficient method of 1,2,3-triazole synthesis is described in which these heterocyclics are formed through a novel nitrogen transfer from diazocarbonyl compounds to enaminones. Thus, the reaction of 3-diazo-1,3-dihydro-2H-indol-2-one derivatives 1 (X = NR3) and 3-diazobenzo[b]-thiophen-2(3H)-one 5 (X = S) with enaminones 2 and 7 leads to the formation of mainly 1,2,3-triazoles 4 and pyrazoloquinazolinones 3. Both the phenyl substituents (Y and Z in 1) and the nature of the X group affects the reaction rate and product distribution. Rate increases with an increase in the electron-withdrawing ability of the substituents Y and Z. The dinitro derivative 1g is shown to be the most efficient in promoting 1,2,3-triazole 4 formation while pyrazoloquinazolinones 3 are often competitively formed when other derivatives of 1 are employed.
