| abstract |
The invention concerns nitrogenated heterocyclic compounds, their preparation and use as antibacterial drugs, compounds of general formula (I) n n n n n n n n n n wherein R 1 represents a (CH 2 ) n —NH 2 or (CH 2 ) n —NHR radical, where R is a (C 1 -C 6 ) alkyl and n is equal to 1 or 2;n R 2 represents a hydrogen atom; R 3 and R 4 together form an aromatic nitrogenated heterocycle with 5 apexes with 1, 2 or 3 nitrogen atoms optionally substituted by one or several R′ groups, R′ being selected in the group composed of a hydrogen atom and alkyl radicals with 1 to 6 carbon atoms; in free form, as zwitterions, and in the form of salts of pharmaceutically acceptable inorganic or organic bases and acids. |
