(A) were determined and values indicate that the cationic series is characterized by good surface‐active and self‐aggregation properties. For the first time, we reported the anthelmintic activities against the rodent gastrointestinal nematode Heligmosomoides polygyrus bakeri, in vitro for cationic gemini compounds. In the series of five tested cationic compounds (4a–e), three of them (4a, 4b and 4d)
制备了一系列新的阳离子二聚表面活性剂,包括缩酮化反应,Williamson醚化和与叔烷基胺的区域选择性环氧乙烷开环。通过使用柱色谱的简单纯化程序以高纯度获得合成的化合物。测定了临界胶束浓度(CMC),表面张力降低的有效性(γCMC),表面过量浓度(Γ)和界面上每分子的面积(A),这些值表明阳离子系列具有良好的表面活性-主动和自聚集属性。首次,我们报道了对啮齿动物胃肠线虫Heligmosomoides polygyrus bakeri的驱虫活性。,用于阳离子双子座化合物的体外。在一系列五个测试的阳离子化合物(4a - e)中,其中三个(4a,4b和4d)显示出在不同浓度下具有出色的体外驱虫活性。发现驱虫活性取决于阳离子化合物的类型,浓度和孵育时间。该系列的阳离子di-C 12(4a)衍生物是最好的驱虫剂,在最小浓度为50 ppm且孵育60分钟的情况下,使用最佳。
