  摘要：

  十二个亲脂性1,3-二甲苯基-21-crown-6大环聚醚2-羧酸，两个套索醚1,3-二甲苯基-21-crown-6大环聚醚2-羧酸和两个1,3-二甲苯基-28合成了-crown-8大环聚醚2-羧酸，并测试了它们在鸡中的体外抗菌活性，瘤胃丙酸生成的体外刺激作用和体内抗球虫活性。这些是与动物保健领域相关的生物学筛选，其中离子载体抗生素（如莫能菌素）已被发现。虽然没有亲脂性取代基的母体结构1在生物学上没有活性，但亲脂性大环化合物在两次体外试验中均具有活性，但对鸡球虫病却没有活性。在牛中测试了一种化合物，发现其在瘤胃发酵中会增加丙酸的水平。该效应被认为是提高离子载体抗生素莫能菌素所表现出的牛饲料利用效率的重要因素。这些亲脂性大环聚醚羧酸的碱金属盐非常溶于有机溶剂，不溶于水。提出这些化合物在上述生物系统中充当离子载体试剂和离子载体抗生素的功能模拟物。
