The present invention relates to new antimicrobial compounds, their synthesis and their use for treatment of mammalian infections. The present invention aims at the generation of new compounds with activity against mycobacteria as potential new tuberculosis drugs to overcome problems concerning resistance and drug intolerance. This aim has been solved by providing compounds of the formula 1 wherein R1 and R2 are, independently of each other, NO2, NR7R8, NHOR9, COOR9, CN, CONR10R11, CHO, F, Cl, Br, SO2NR12R13, lower alkoxy, OCF3, mono-, di or trifluoromethyl; R3 and R4 are, independently of each other, H, a saturated or unsaturated, linear or branched aliphatic radical having 1 -3 chain members, F, Cl, Br, lower alkoxy; R5 is H, a saturated or unsaturated, halogenated or unhalogenated, linear or branched aliphatic radical having 1-7 chain members; R is a radical: wherein X is saturated or unsaturated, halogenated or unhalogenated, linear or branched aliphatic radical having 1-5 chain members, or R5 and R6 together represent bivalent radicals wherein n is 1-4: R7 - R13 are, independently of each other H or a saturated or unsaturated, halogenated or unhalogenated, linear or branched aliphatic radical having 1 -5 chain members, phenyl, benzyl or R7 and R8 together R10 and R11 together, R12 and R13 together represent a linear or branched aliphatic bivalent radical having 1 -7 chain members; R14 and R15 are, independently of each other, H, linear or branched aliphatic radical having 1 -5 chain members, F, Cl, Br, NO2, NH1, CF3. |
