The invention relates to novel 5-phenylcarbamoylthiobarbituric acid derivatives of the general formula ##STR1## wherein R.sub.1 and R.sub.2 are each independently C.sub.1 -C.sub.5 alkyl or methoxy, R.sub.3 is unsubstituted phenyl, unsubstituted pyridyl, or phenyl which is substituted by 1 to 3 identical or different members selected from the group consisting of C.sub.1 -C.sub.5 alkyl, C.sub.1 -C.sub.4 cyanoalkyl, halogen, nitro and C.sub.1 -C.sub.5 haloalkyl containing 1 to 5 halogen atoms, or is pyridyl which is substituted by 1 to 3 identical or different members selected from the group consisting of C.sub.1 -C.sub.5 alkyl, halogen, nitro and C.sub.1 -C.sub.5 haloalkyl containing 1 to 5 halogen atoms and R.sub.4 and R.sub.5 are each independently hydrogen, halogen, C.sub.1 -C.sub.5 alkyl, C.sub.1 -C.sub.2 haloalkyl containing 1 to 3 halogen atoms, or are C.sub.1 -C.sub.3 -alkoxy or nitro, and to the tautomers and salts thereof, as anthelmintics. The compounds may be used by themselves or together with suitable carriers and further adjuvants for controlling helminths which are parasites of animals.
该发明涉及一种新颖的通式为 ##STR1## 的5-苯基羰基硫代异恶唑酸衍生物,其中R.sub.1和R.sub.2分别独立地为C.sub.1-C.sub.5烷基或甲氧基,R.sub.3为未取代的苯基、未取代的吡啶基或被1到3个相同或不同的成员取代的苯基,这些成员选自C.sub.1-C.sub.5烷基、C.sub.1-C.sub.4氰基烷基、卤素、硝基和含有1到5个卤素原子的C.sub.1-C.sub.5卤代烷基,或者是被1到3个相同或不同的成员取代的吡啶基,这些成员选自C.sub.1-C.sub.5烷基、卤素、硝基和含有1到5个卤素原子的C.sub.1-C.sub.5卤代烷基,R.sub.4和R.sub.5各自独立地为氢、卤素、C.sub.1-C.sub.5烷基、含有1到3个卤素原子的C.sub.1-C.sub.2卤代烷基,或者为C.sub.1-C.sub.3-氧烷基或硝基,以及其互变异构体和盐,作为驱虫剂。这些化合物可以单独使用,也可以与适当的载体和其他辅助剂一起用于控制寄生在动物体内的蠕虫。
