Four new derivatives of 8‐piperazine ethyl xanthine were synthesized and their bronchospasmolytic activity and A1‐adenosine affinity were studied. Their relaxant action in the tracheal muscle was lower than that of theophylline and that of theophylline derivatives substituted at the 7‐position. Only compound 9, where the methyl group in the 1‐position of the theophylline was substituted by an isobutyl
合成了 8-哌嗪乙基黄嘌呤的四种新衍生物,并研究了它们的支气管痉挛活性和 A1-腺苷亲和力。它们在气管肌肉中的松弛作用低于茶碱和 7 位取代的茶碱衍生物。只有化合物 9,其中茶碱 1 位的甲基被异丁基取代,对 A1-腺苷受体显示出良好的亲和力。
