  Various pyrazine derivatives were synthesized and their antiallergic activity was examined. The inhibitory activity on allergic histamine release of the compounds bearing a 5-tetrazolyl group was more potent than that of the corresponding carboxyl derivatives. The introduction of -CONH- or -NHCO- between the pyrazine ring and the 5-tetrazolyl group as a spacer greatly enhanced the activity. N-(1H-

  合成了各种吡嗪衍生物，并检查了它们的抗过敏活性。带有5-四唑基的化合物对过敏性组胺释放的抑制活性比相应的羧基衍生物更有效。在吡嗪环和5-四唑基之间作为间隔基引入-CONH-或-NHCO-大大提高了活性。N-（1H-替硝唑-5-基）-2-吡嗪甲酰胺（I-3）估计显示出与色甘酸二钠（DSCG）几乎相同的效价。研究了通过将一些取代基引入I-3的吡嗪环的3位，5位或6位而修饰的各种衍生物之间的构效关系。当取代基如甲基，氯，甲氧基，在3-或5-位引入甲基氨基和二甲基氨基。相反，具有各种烷基氨基的6-取代或多或少地增加了活性。其中，6-二甲基氨基（I-17c）和6-（1-吡咯烷基）（I-34）衍生物被证明是最有效的。测定I-17c和I-34的IC 50值（对变应性组胺释放产生50％抑制的浓度）分别为4.7×10（-10）和4.6×10（-10）M。这两种化合物不仅通过静脉内途径（两种化合物的ED50 =
