NUEVOS COMPUESTOS HETEROCICLICOS NITROGENADOS, SU PREPARACION Y SU UTILIZACION COMO MEDICAMENTOS ANTIBACTERIANOS

LA PRESENTE INVENCIÓN TRATA DE COMPUESTOS HETEROCÍCLICOS NITROGENADOS, SU PREPARACIÓN Y SU UTILIZACIÓN COMO MEDICAMENTOS ANTIBACTERIANOS, ESPECIALMENTE CONTRA PSEUDOMONAS AUREGINOSA Y SOBRE MODELOS DE INFECCIÓN ANIMAL POR CEPAS RESISTENTES A LOS AGENTES ANTIBACTERIANOS COMÚNMENTE UTILIZADOS. The invention concerns nitrogenated heterocyclic compounds, their preparation and use as antibacterial drugs, compounds of general formula (I) wherein R1 represents a (CH2)n-NHR2 or (CH2)n-NHR radical, where R is a (C1-C6) alkyl and n is equal to 1 or 2; R2 represents a hydrogen atom; R3 and R4 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.
