possible explanation of the effects induced by the nature of the substituents and of their position. Some of the compounds were tested for their ability to inhibit human platelet aggregation in vitro induced by arachidonic acid. Only compound 26 showed interesting antiplatelet activity.
几种1,8-萘啶衍生物已被重氮化以获得相应的羟基衍生物或羟基和羟基硝基衍生物的混合物。羟基和羟基硝基衍生物的各自量取决于取代基的性质,它们在萘啶核上的位置,亚硝酸钠的量以及反应温度。对某些分子的电子密度的研究表明,可能是由取代基的性质及其位置引起的影响的解释。测试了某些化合物在体外抑制花生四烯酸诱导的人血小板聚集的能力。仅化合物26显示出令人感兴趣的抗血小板活性。
