NITROGEN-CONTAINING HETEROCYCLIC COMPOUNDS, SYNTHESIS AND USE THEREOF AS ANTIBACTERIAL MEDICINAL AGENTS

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to compounds of formula (I), having antibacterial properties, a method for synthesis thereof, use thereof and a pharmaceutical composition based on said compounds. In general formula (I) R₁ is a (CH₂)_n-NH₂ or (CH₂)_n-NHR radical, where R is (C₁-C₆)alkyl and n equals 1 or 2; R₂ is a hydrogen atom; R₃ and R₄ together form a nitrogen-containing aromatic 5-member heterocycle with 1, 2 or 3 nitrogen atoms, possibly substituted with one or more R' groups, where R' is selected from a group consisting of a hydrogen atom and alkyl radicals with 1-6 carbon atoms.;EFFECT: improved method.;13 cl, 4 ex
