novel 5-hydroxyalkylamino-1,2-dihydrothieno[2,3-h][1,6]naphthyridines were prepared by the reaction of 5-chloro-1,2-dihydrothieno[2,3-h][1,6]naphthyridine derivatives with some aminoalcohols in the presence of base. These derivatives were cyclized to the corresponding imidazo or pyrimido derivatives. The bronchodilatory activity of these compounds was evaluated on the basis of their relaxation activity
一些新颖的5-羟基烷基-1,2-二氢[2,3- ħ ] [1,6]通过5-氯-1,2-二氢[2,3-反应制备萘啶ħ ] [1,6在碱的存在下]萘啶衍生物与一些氨基醇。这些衍生物被环化为相应的咪唑或嘧啶衍生物。这些化合物的支气管扩张活性是根据它们对氨甲酰胆碱氯化物诱导的气管收缩的松弛活性进行评估的,以此作为主要的体外测定方法。还评估了一些萘啶对氨基甲酰胆碱氯化物诱导的气管收缩的影响,该反应存在或不存在作为磷酸二酯酶III或IV抑制剂的米力农或4-(3-丁氧基-4-甲氧基苯基)咪唑啉-2--2-酮。
