NEW 4-AMINOPYRIDINES, PROCESS FOR PREPARING THE SAME AND MEDICAMENTS CONTAINING THE SAME

摘要

New 4-aminopyridines have general formula (I), in which R<1> stands for the groups R<6>-SO-NR<7>, R<6>-SO2-NR<7>, R<6>-NR<7>-SO-, R<6>-NR<7>-SO2-, R<6>-SO-O-, R<6>-SO2-O-, R<6>-O-SO- or R<6>-O-SO2; R<2> stands for a hydrogen or halogen atom, a cyano, alkyl, alkoxy or halogen alkyl group; X stands for an oxygen atom, a sulphur atom or the NH group; R<3> and R<4> are the same or different and stand for hydrogen atoms or alkyl groups; R<5> stands for a hydrogen atom, an alkyl group or the aralkyl group; R<6> stands for an aliphatic or cyclic, if required substituted residue; R<7> stands for a hydrogen atom or an aliphatic or cyclic, if required substituted residue; Y stands for a linear or branched alkylene chain; R<8> and R<9> are the same or different and stand for hydrogen atoms, aralkyl, cycloalkyl or alkyl groups which may be substituted once or several times by halogen, hydroxy, alkoxy, alkylcarbonyloxy, amine or carboxy, or R<8> and R<9> form together with the N atom to which they are bound a saturated ring which may contain an additional oxygen, sulphur or nitrogen atom. Also disclosed are the hydrates, solvates and physiologically acceptable salts of these compounds, their optically active forms, racemates and diastereomer mixtures, a process for preparing said compounds, medicaments containing said compounds and the use of said compounds for producing medicaments.
