Reaction of 3-amino derivatives of the nematocides tetramisole and levamisole with variously substituted benzoylisocyanates gave a series of benzoylureas I which were tested for activity against helminths and ectoparasites. Compounds bearing 2,6-difluoro and 4-trifluoromethyl substituents had potent nematocidal activity in both mice and sheep. No antiectoparasitic activity was observed.
线虫杀虫剂四咪唑和左旋咪唑的3-氨基衍生物与各种取代的苯甲酰基异氰酸酯的反应产生了一系列苯甲酰脲I,测试了其对蠕虫和体外寄生虫的活性。带有2,6-二氟和4-三氟甲基取代基的化合物在小鼠和绵羊中均具有有效的杀线虫活性。没有观察到抗寄生虫活性。
