Abstract

Compuşii cu formula generală (I):în care fie că R1 şi R2, care sunt identici sau diferiţi, reprezintă atom de hidrogen sau radical de hidrocarbură, saturat sau nesaturat, conţinând până la 24 atomi de carbon, fiind eventual întrerupt prin unul sau mai mulţi heteroatomi şi având una sau mai multe grupări funcţionale; fie că R1 şi R2, împreună cu atomul de azot, cuplat cu ei, formează un inel heterociclic, ce conţine eventual unul sau mai mulţi heteroatomi, selectaţi dintre azot, oxigen sau sulf; fie că R1 şi R2, luaţi împreună, formează un radical (a), în care R'1 şi R'2, care sunt identici sau diferiţi, reprezintă atom de hidrogen sau radical de hidrocarbură, saturat sau nesaturat, conţinând până la 23 atomi de carbon, fiind eventual întrerupt prin unul sau mai mulţi heteroatomi şi conţinând una sau mai multe grupări funcţionale, şi Z reprezintă un atom de hidrogen sau un rest de acid carboxilic, conţinând până la 18 atomi de carbon, precum şi sărurile lor aditive cu acizii compuşilor cu formula (I). Compuşii cu formula (I) posedă proprietăţi antibiotice valoroase.Compounds of general formula (I): wherein either R 1 and R 2, which are the same or different, represent a saturated or unsaturated hydrogen or hydrocarbon radical containing up to 24 carbon atoms, possibly interrupted by one or more many heteroatoms and having one or more functional groups; or that R 1 and R 2, together with the nitrogen atom, coupled thereto, form a heterocyclic ring, possibly containing one or more heteroatoms, selected from nitrogen, oxygen or sulfur; either R 1 and R 2, taken together, form a radical (a), wherein R 1 and R 2, which are the same or different, represent a saturated or unsaturated hydrogen atom or hydrocarbon radical containing up to 23 atoms. of carbon, possibly interrupted by one or more heteroatoms and containing one or more functional groups, and Z represents a hydrogen atom or a carboxylic acid moiety, containing up to 18 carbon atoms, as well as their additive salts with acids. of compounds of formula (I). The compounds of formula (I) possess valuable antibiotic properties.
