Sulphonylamino-benzimidazole compounds of formula (I), and their tautomers, stereoisomers and salts, are new. R1 = phenyl (optionally mono- to tri-substituted by F, Cl, Br, alkyl, CF3, OH, alkoxy, NH2, alkylamino, dialkylamino, alkylcarbonylamino, alkylthio, alkylsulphinyl, alkylsulphonyl, alkylsulphonylamino, COOH, alkoxycarbonyl, Ar, OAr, NHCOAr or NHSO2Ar), quinolyl or 1,2,3,4-tetrahydroquinolyl, (both bonded at the benzo ring, and optionally mono- or di- substituted in the aryl part by F, Cl, Br, alkyl or alkoxy), Ar-substituted ethenyl, NH2, alkylamino or dialkylamino, or a group of formula (a) (optionally substituted by alkyl); Ar = phenyl (optionally mono- or di-substituted, by F, Cl, Br, alkyl or alkoxy; R2, R4-R7 = H or alkyl; R3 = H, alkyl, OH or alkoxycarbonyl; A1 = O, S or NRa; A2, A3 = C(Rb) or N; Ra = H, alkyl or Ar; Rb = H, F, Cl, Br, alkyl, COOH, alkoxycarbonyl or alkylcarbonylamino; alkyl and alkoxy have 1-3 C. |
