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

摘要

The present invention relates to the use of 6(7)-amino-substituted 5,8-quinolinediones of the general formula (I) IMAGE in which R1 represents substituted C1-C6-alkyl, and optionally substituted cycloalkylalkyl, cycloalkyl, aralkyl or aryl, where halogen, nitro, alkyl, alkylamino, aminoacyl, aryl, aryloxy, arylthio, aralkyl, haloalkyl, alkoxy, haloalkoxy, alkylthio, haloalkylthio, alkylsulphinyl, haloalkylsulphinyl, alkylsulphonyl or haloalkylsulphonyl may be mentioned as substituents, R2 represents hydrogen or alkyl or R1 and R2, together with the adjacent N atom, represent a carbocyclic 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, R4 represents alkyl, to combat endoparasites in medicine and veterinary medicine, and to novel 6(7)-amino-substituted 5,8-quinolinediones and their preparation.
