Compounds that respond to the structural formula (see Formula) their pharmaceutically acceptable salts, prodrugs or derivatives thereof, wherein R1 is selected from H, a linear or branched (C1-C5) alkyl group and a COR4 R2 group is selected from H, a linear or branched (C1-C5) alkyl group and a COR5 R3 group is selected from H, a linear or branched (C1-C5) alkyl group, a linear or branched (C1-C5) alkyl group , a cycloalkyl of (C5-C6) carbons, an aryl group, an alkyl (C1-C5) aryl group and where the aryl group may be unsubstituted or substituted by one or more R6 groups and an NHCOR5 or R2 and R3 group together they form with the N a piperidino group, a morpholino group or a piperazino group, substituted or unsubstituted; R4 is selected from H and a (C1-C5) alkyl group; R5 is selected from substituted or unsubstituted aryl by one or more R6, pyridyl, linear or branched (C1-C5) alkyl groups and a pyridino group, R6 is selected from (C1-C5) alkyl, halogen and nitro groups, with the except that R1, R2 and R3 cannot be at the same time H. The compounds have antibacterial activity. |
