The invention concerns nitrogenated heterocyclic compounds, their preparation and use as antibacterial drugs, compounds of general formula (I)
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;
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.
这项发明涉及氮
杂环化合物,它们的制备和用作抗菌药物,通式(I)中的化合物,其中R1代表(
CH2)n—NH2或( )n—NHR基团,其中R为(C1-C6)烷基,n等于1或2;R2代表氢原子;R3和R4共同形成一个具有5个顶点的芳香氮杂环,其中1、2或3个氮原子可以选择性地被一个或多个R′基团取代,其中R′选自由一个氢原子和含有1至6个碳原子的烷基基团的组成;以自由形式、离子缔合物形式和以药用可接受的无机或有机碱和酸的盐形式存在。
