Patent

CA 2259217

The invention concerns new quinolone carbonic acids substituted by 7-(3-vinyl- 1,4-piperazine-1-yl) of general formula (I) in which R1 stands for hydrogen or alkyl optionally substituted by hydroxy, methoxy, amino, methylamino or dimethylamino with 1 to 4 carbon atoms or (5-methyl-2-oxo-1,3-dioxol-4-yl)- methyl; R2 stands for hydrogen or fluorine when at the same time R4 is a different hydrogen or fluorine, or stands for amino, methyl or vinyl; R3 stands for hydrogen, benzyl, alkyl with 1 to 3 carbon atoms, groups of -CH=CH- COOR5, -CH2CH2-COOR5, -CH2CH2CN, -CH2CH2COCH3, -CH2COCH3, in which R5 stands for methyl or ethyl or stands for a group of the general structure R6-(NH-CHR7- CO)n- in which R6 stands for hydrogen, alkyl with 1 to 3 carbon atoms or stands for the -COO-tertiary butyl group, R7 stands for hydrogen, alkyl with 1 to 4 carbon atoms, hydroxyalkyl with 1 or 2 carbon atoms, CH2-phenyl, aminoalkyl or thioalkyl with 1 or 2 carbon atoms and n = 1 or 2; and R4 stands for hydrogen or flourine when R2 stands for amino, methyl or vinyl or stands for chlorine, methoxy, difluoromethoxy, CN or ethinyl. The invention also concerns a method for their use and their use in antibacterial substances.

L'invention concerne de nouveaux acides quinolone-carboxyliques substitués par 7-(3-vinyl-1,4-pipérazin-1-yle), de formule générale (I), dans laquelle R?1¿ représente hydrogène, alkyle comportant 1 à 4 atomes de carbone, éventuellement substitué par hydroxy, méthoxy, amino, méthylamino ou diméthylamino, ou (5-méthyl-2-oxo-1,3-dioxol-4-yl)-méthyle; R?2¿ représente hydrogène ou fluor (quand en même temps R?4¿ ne représente pas hydrogène ou fluor) ou représente amino, méthyle ou vinyle; R?3¿ représente hydrogène, benzyle, alkyle comportant 1 à 3 atomes de carbone, des résidus de structure -CH=CH-COOR?5¿, -CH¿2?CH¿2?-COOR?5¿, -CH¿2?CH¿2?CN, -CH¿2?CH¿2?COCH¿3?, -CH¿2?COCH¿3?, dans lesquels R?5¿ représente méthyle ou éthyle, ou un résidu de structure générale R?6¿-(NH-CHR?7¿-CO)¿n?, dans laquelle R?6¿ représente hydrogène, alkyle comportant 1 à 3 atomes de carbone ou le résidu COO-butyle tertiaire, R?7¿ représente hydrogène, alkyle comportant 1 à 4 atomes de carbone, hydroxyalkyle comportant 1 ou 2 atomes de carbone, CH¿2?-phényle, aminoalkyle ou thioalkyle comportant 1 ou 2 atomes de carbone, et n vaut 1 ou 2; R?4¿ représente hydrogène ou fluor quand R?2¿ représente amino, méthyle ou vinyle, ou représente chlore, méthoxy, difluorméthoxy, CN ou éthinyle. L'invention concerne également l'utilisation desdits acides comme agents antibactériens.
