derivatives and related compounds with substituent variations at the 2, 3, and 5--9 positions was prepared and evaluated for antiallergy activity using the rat PCA assay. These compounds were obtained by the condensation of the appropriately substituted 2-aminoquinoline-3-carboxamides with dialkyl oxalates, followed by further chemical transformations. More than two-thirds of the compounds prepared exhibited
制备了一系列50多种新的3,4-二氢-4-氧嘧啶基[4,5-b]喹啉-2-羧酸衍生物和相关化合物,这些化合物在2、3和5--9位具有取代基变化并使用大鼠PCA分析评估抗过敏活性。这些化合物是通过将适当取代的2-氨基喹啉-3-甲酰胺与草酸二烷基酯缩合,然后进行进一步的化学转化而获得的。所制备的化合物中有三分之二以上的静脉内活性为色甘酸二钠(DSCG)的1至400倍。结构活性数据表明,在2位上存在羧酸部分可提供最佳效价,并且酯对于良好的口服吸收是优选的。最佳口服活性,ED50值为0.3至3.0 mg / kg,
