Use of 6(7)-amino-substituted quinoline-5,8-quinones for combating endoparasites, new 6(7)-amino-substituted quinoline-5,8-quinones and processes for their preparation A b s t r a c t The present invention relates to the use of 6(7)-amino-substituted quinoline-5,8-quinones of the general formula (I) (I) in which R1 represents substituted C1-C6-alkyl or optionally substituted cycloalkylalkyl, cycloalkyl, aralkyl or aryl, substituents which may be mentioned being halogen, nitro, alkyl, alkylamino, aminoacyl, aryl, aryloxy, arylthio, aralkyl, halogenoalkyl, alkoxy, halogenoalkoxy, alkylthio, halogenoalkylthio, alkylsulphinyl, halogenoalkylsulphinyl, alkylsulphonyl or halogenoalkylsulphonyl, R2 represents hydrogen or alkyl, or R1 and R2, together with the adjacent N atom, represent a carbocyclic Le A 28 421 5-, 6- or 7-membered ring, which can optionally also be interrupted by O, N or S and is optionally substituted by C1-4-alkyl, R3 represents halogen or -S-R4 and R4 represents alkyl, for combating endoparasites in medicine and veterinary medicine, and to new 6(7)-amino-substituted quinoline5,8-quinones and their preparation.
