carboxylates were synthesised and their structures were identified by 1H NMR, MS, and IR spectra. The anticoccidialactivities of these compounds were evaluated according to the ACI (the anticoccidial index) method. The results showed that two of these compounds exhibited anticoccidialactivities against Eimeria tenella in the chicken’ diet with a dose of 27 mg kg−1.
合成了八种新型 7-烷基-6-(2-芳氧基乙氧基)-4-羟基喹啉-3-羧酸乙酯,并通过 1 H 核磁共振、质谱和红外光谱鉴定了它们的结构。根据ACI(抗球虫指数)方法评价这些化合物的抗球虫活性。结果表明,其中两种化合物对鸡日粮中的艾美球虫表现出抗球虫活性,剂量为 27 mg kg-1。
